A personalised topical cream containing tretinoin at 0.01%, the gentlest strength in the Gro Skin ladder. Designed for adults new to retinoid treatment, those with very sensitive skin, or patients who have needed to step down from 0.025%. Applied to clean, dry skin at night.
Compounded by APC Labs Ltd, Southampton (GPhC 9012301)
Single active ingredient at the gentlest starting concentration
Pack size: 30g tube, approximately one month at nightly use
Skin change is easy to dismiss until you catch yourself in a photo you didn’t expect. Firstly, the signs are familiar: fine lines building around the eyes, uneven tone across the cheeks, texture that never feels quite settled. However, the less visible impact is often harder to carry. Confidence dips at the wrong moments. Meanwhile, the frustration of trying yet another cream that doesn’t shift things becomes part of daily life.
The problem with standard retinoids
For many people, the frustration goes beyond the skin concern itself. In particular, it’s about the experience of trying to treat it. Standard over-the-counter retinols are often too weak to move the needle. Meanwhile, standard prescription tretinoin starts at 0.025%, which for sensitive skin can bring peeling, redness, and irritation that stops treatment in its tracks. As a result, after a few weeks of that, skipping nights starts to feel reasonable. Above all, skipping nights is exactly what stops retinoid treatment from working.
Why 0.01% tretinoin?
Not every patient should start at 0.025%. Firstly, some skin types react so strongly that the standard entry-level strength triggers weeks of irritation. Additionally, others have tried 0.025% before and needed to step down to something gentler. Meanwhile, some people simply want the slowest, most controlled introduction to retinoid treatment possible. As a result, the Gro Skin range now includes 0.01% as the gentlest option in the tretinoin ladder, sitting below the standard 0.025%, 0.05%, and 0.1% strengths. Above all, this is a considered clinical choice, not a compromise.
A medically responsible route
At Courier Pharmacy, treatment starts with a proper assessment. Firstly, suitability is checked. Additionally, the decision to prescribe this compounded cream is a clinical one, based on your skin, your history, and your goals.

This compounded topical cream contains tretinoin at 0.01% in a moisturising base. In particular, it’s designed for adults who need the gentlest possible introduction to retinoid treatment. Meanwhile, it also suits patients who have reacted to standard prescription tretinoin at 0.025%. Additionally, at 0.01%, the strength allows for gradual retinisation without the initial irritation that stops so many people from continuing. As a result, the aim is straightforward: give the skin the smoothest possible route into retinoid treatment, in a strength chosen specifically for the individual.

Safe prescribing still matters: this cream needs proper screening, review, and follow-up
Part of the Gro Skin range, designed for personalised compounded skincare
Skin concerns are personal
Skin concerns are common, but that does not make them any less personal. Firstly, many people first notice fine lines building, tone unevenness, or texture that stops feeling smooth. Additionally, many then try a product that does not suit their skin, see little result or worse, and quietly give up. Meanwhile, this is not because retinoids cannot work. As a result, it’s often because they were never on the right strength or the right base to begin with.
A cream for people who need a gentle start
This Gro Skin cream is aimed at people who want a considered, gentle-first approach to retinoid treatment. In particular, it’s relevant for those whose skin has always reacted strongly to actives. Meanwhile, it also suits those whose prescriber has identified 0.01% as the right starting point after a poor experience with stronger strengths. Additionally, it works for anyone who wants the slowest, most controlled introduction to tretinoin possible. As a result, it brings prescription-strength retinoid benefit with the smallest initial impact on the skin barrier.
The goal of treatment
Skin change affects more than appearance. Firstly, it chips away at how you feel in your own skin. Additionally, it makes ordinary moments feel oddly loaded, a harsh bathroom mirror, a photo taken from an unexpected angle, a video call under office lighting. Meanwhile, the goal of retinoid treatment is not perfection. As a result, it is to smooth texture, even tone, and build long-term skin health, with a plan that makes clinical sense and a strength that makes daily use something you can actually stick to.
The Gro Skin tretinoin ladder
Why a ladder exists
Not every skin should start at the same strength. Firstly, some skin types tolerate 0.025% straight away. Meanwhile, others need weeks at a lower concentration before they can move up. Additionally, some patients never need to move beyond 0.01% at all, because the gentlest strength gives them the results they want. As a result, the ladder is a clinical framework, not a marketing gimmick. Your prescriber selects the rung that matches your skin.
Where 0.01% sits
The Gro Skin tretinoin ladder runs 0.01%, 0.025%, 0.05%, and 0.1%. In particular, 0.01% is the gentlest entry point. Meanwhile, 0.025% is the standard prescription starting strength. Additionally, 0.05% is the mid-range, and 0.1% is the highest strength for established users or specific indications. As a result, starting at 0.01% gives room to move up in a controlled way, if and when your skin is ready.
Retinisation, not sensitisation
Retinisation is the process of your skin adapting to a retinoid. Firstly, it takes 4 to 12 weeks. Additionally, mild dryness, tightness, or fine peeling can occur even at 0.01%. Meanwhile, real irritation, stinging, or burning is a sign the strength is too high or the frequency is too much. As a result, the ladder approach and the low starting strength minimise the difference between retinisation and true sensitisation.
Why compounding?
What compounding means
Compounding means a medicine is prepared to order by a licensed pharmacy for an individual patient. In particular, it is not a mass-produced one-size-fits-all product. Meanwhile, in the UK, this sits within a regulated framework and should only be supplied when clinically appropriate.
Why compounding matters for this cream
Some people choose a compounded cream because the strength they need, such as tretinoin 0.01%, does not exist in any standard licensed product. Additionally, others come to compounding specifically because they want a fresh formulation rather than a jar that has been sitting on a shelf. Meanwhile, others need the flexibility to move up or down the strength ladder as their skin responds. As a result, compounding makes this ladder approach possible in the first place.
Personalised skincare in practice
Skin is not identical from one person to the next. Firstly, the right tretinoin strength for one patient is not the right strength for another. Additionally, skin sensitivity, previous retinoid history, and skin concern all matter. Meanwhile, compounding makes it possible to prescribe tretinoin 0.01%, a strength that simply does not exist in any standard licensed product, when clinical assessment indicates that this is the most appropriate starting point. As a result, the medicine is shaped around the patient, not the other way around.
Why a low-strength first approach can be the right choice
Not every patient needs to start at standard prescription strength. In particular, for some, a low-strength introduction is the most clinically appropriate way to begin. Meanwhile, it lets the skin adapt without the retinisation phase becoming a barrier to continuing. Additionally, it also allows the prescriber to review response before deciding whether to move up the ladder. As a result, starting low matches the biology of retinoid tolerance for patients who need this approach.
Why the 30-day shelf life
Tretinoin is unstable
Tretinoin degrades on exposure to light, air, and heat. Firstly, this is well-established chemistry. Additionally, even a well-sealed tube loses some active over time. Meanwhile, a jar or tube sitting on a shelf for months contains less active tretinoin than the label states. As a result, the shorter the time between compounding and use, the more of the labelled strength actually reaches your skin.
Made fresh, used within the month
APC Labs compounds each tube to order. In particular, this means it’s made close to the date you receive it. Additionally, the 30-day shelf life reflects the honest reality of how long the cream stays at labelled strength. Meanwhile, using it within the month means you get what’s on the label from first application to last. As a result, treatment isn’t undermined by an ageing tube.
Storage matters
Meanwhile, storing the cream correctly extends the useful life within that 30 days. Firstly, keep it cool, away from direct sunlight. Additionally, always replace the cap immediately after use. Above all, don’t leave the tube in a hot bathroom or by a sunny window. Furthermore, refrigeration is not required but is fine if you prefer it.
The Gro Skin range
What is Gro Skin?
Gro Skin is the compounded skincare range from Courier Pharmacy. Firstly, it’s the sister range to Gro hair loss. Additionally, it exists because skincare should not feel one-size-fits-all. Meanwhile, some people need a gentle low-strength retinoid. Others need a stronger option or a different active. Furthermore, some benefit from a combination cream. As a result, Gro Skin brings those options together under one brand, matching treatment to the person using it.
Why Gro Skin is different
Gro Skin was built around three practical goals. Firstly, personalisation: a ladder of strengths and combinations, chosen for you. Additionally, freshness: every cream compounded to order with a 30-day shelf life. Meanwhile, better tolerability: strengths and combinations designed to match your skin, not fight it.
Ingredients used across the Gro Skin range
Depending on the product selected, Gro Skin formulations may include:
Tretinoin (0.01%, 0.025%, 0.05%, or 0.1%)
Niacinamide (multiple strengths)
Azelaic acid (multiple strengths)
Combination creams (tretinoin plus niacinamide, plus azelaic acid, or all three)
These can be prescribed alone or in combination, depending on the individual treatment plan.
Gro Skin product options
The Gro Skin range includes tretinoin-only creams (0.01%, 0.025%, 0.05%, and 0.1%), niacinamide-only creams, azelaic acid-only creams, and combination creams that bring two or three actives together in a single formulation. Meanwhile, all Gro Skin products come in 30g tubes designed for around one month of use. Additionally, all Gro Skin creams are compounded fresh with a 30-day shelf life.
In simple terms
Gro Skin makes personalised skincare accessible. Firstly, you get a compounded cream, made fresh for your skin, at a strength chosen for you. Additionally, whether you need the gentlest tretinoin at 0.01% or the strongest at 0.1%, or a combination cream that layers actives without you having to buy three separate products, Gro Skin fits itself to your skin, not the other way around. As a result, whatever your concern, the range gives you more than one route without making the choice complicated.

Active ingredient in Gro Skin Tretinoin 0.01% Cream
Tretinoin 0.01%
Tretinoin is a vitamin A derivative, also known as all-trans retinoic acid. In particular, it binds to nuclear retinoic acid receptors in skin cells. Meanwhile, this triggers changes that speed up cell turnover, unclog pores, and stimulate collagen production. As a result, tretinoin is the most studied topical retinoid in dermatology. At 0.01%, this is the gentlest starting strength in the Gro Skin ladder, chosen by the prescriber when a slow, controlled introduction is the most appropriate approach.
Why the cream base matters
The cream base is designed for skin tolerance. Firstly, it delivers tretinoin without the alcohol-heavy vehicles that can worsen dryness. Meanwhile, it supports the barrier during retinisation. As a result, it makes daily application more comfortable, which supports the consistency retinoid treatment needs.
What is Gro Skin Tretinoin 0.01% Cream used for?
Early photoageing and fine lines
This cream is used for early photoageing, fine lines, and skin renewal support. In particular, tretinoin is the gold-standard topical retinoid for these concerns. Meanwhile, at 0.01%, the effect is gentler and slower than at higher strengths. Additionally, this suits patients who want to start conservatively. As a result, the aim is to support long-term skin health with the smallest initial impact.
Sensitive skin retinoid introduction
Many patients want the benefits of tretinoin but cannot tolerate 0.025% as a starting point. In particular, this includes patients with rosacea, eczema history, or generally reactive skin. Meanwhile, 0.01% allows retinisation to happen more slowly. Additionally, this reduces the likelihood of significant peeling, redness, or discomfort. As a result, treatment becomes sustainable rather than something that gets abandoned in the first month.
Step-down from a higher strength
Some patients start at 0.025% and find their skin cannot tolerate it. Additionally, others develop irritation months into treatment despite an initial good response. Meanwhile, stepping down to 0.01% for a period lets the skin recover while retinoid treatment continues. As a result, the ladder gives room to move both up and down as skin biology changes.
How does Gro Skin Tretinoin 0.01% Cream work?
Speeding up cell turnover
Tretinoin binds to receptors inside skin cells. Firstly, this signals cells to divide and shed more quickly than they would otherwise. Meanwhile, this speeded-up turnover clears dead cells that dull the surface. Additionally, it unclogs pores that would otherwise trap oil and debris. As a result, the skin surface becomes smoother and more even over weeks of use.
Stimulating collagen production
Meanwhile, tretinoin also signals the deeper layers of the skin to produce more collagen. Additionally, collagen is what gives skin its firmness and bounce. In particular, this collagen effect is why tretinoin softens fine lines over months rather than weeks. Furthermore, at 0.01% the collagen-stimulating effect is slower and more gradual than at higher strengths, but still present.
Retinisation over 4 to 12 weeks
Firstly, mild dryness, tightness, or fine flaking can occur in the first few weeks. Additionally, this is the skin adapting to the retinoid signal. Meanwhile, at 0.01% these effects are minimal for most patients but not zero. As a result, giving the skin time to adjust matters. Above all, this is retinisation, not damage.
How long until you see results
You may notice slight smoothness within 4 to 6 weeks. However, visible changes to fine lines and tone usually take 3 to 6 months. Meanwhile, collagen changes continue building well into the second year of consistent use. As a result, patience and consistency matter. Above all, retinoid results are cumulative.
How to use Gro Skin Tretinoin 0.01% Cream
Step-by-step application
Firstly, cleanse your face gently and pat completely dry. Then, wait about 20 to 30 minutes before applying the cream. This waiting step matters. Next, take a pea-sized amount of Gro Skin Tretinoin 0.01% Cream on your fingertip. After that, dot it across the areas being treated (forehead, cheeks, chin), then spread evenly with your fingertips. Finally, wait 10 to 15 minutes before applying moisturiser if you use one.
Starting frequency
Even at 0.01%, don't start with nightly use. Firstly, apply the cream every third night for the first week. Then every other night for the next week. Most patients can move to nightly use after 3 to 4 weeks. However, listen to your skin. If it feels irritated at any stage, drop back down until it settles.
Sun protection is not optional
Above all, tretinoin makes your skin more sensitive to UV. Firstly, always use SPF 30 or higher during the day when using tretinoin. Additionally, this applies even on cloudy days and even when you're mostly indoors. Meanwhile, unprotected sun exposure while using tretinoin will undo the benefits and increase risk of pigmentation and photoageing. As a result, a daily broad-spectrum sunscreen is essential.
What to avoid on the same night
Meanwhile, avoid using tretinoin on the same night as other actives such as AHAs, BHAs, or benzoyl peroxide. Additionally, these combinations increase irritation without adding benefit at 0.01%. Furthermore, use those actives on non-tretinoin nights if you want to include them in your routine. Above all, keep the tretinoin routine simple during retinisation.
Warnings and precautions for Gro Skin Tretinoin 0.01% Cream
Not for pregnancy or planning pregnancy
Above all, topical tretinoin should not be used during pregnancy. In particular, oral retinoids are known teratogens, and while topical absorption is low, the risk profile means tretinoin is avoided during pregnancy and planning. As a result, stop use if you become pregnant. Additionally, use effective contraception during treatment if you are sexually active and could become pregnant. Discuss this fully with your prescriber.
Not for breastfeeding
Similarly, avoid topical tretinoin during breastfeeding. Meanwhile, systemic absorption from topical application is low but not zero. Additionally, safer alternatives (such as azelaic acid) may be more appropriate during this period. As a result, discuss any pregnancy or breastfeeding status during your consultation.
Sun sensitivity
Tretinoin increases sensitivity to ultraviolet light. Firstly, always use SPF 30 or higher daily during treatment. Additionally, avoid deliberate sun exposure or sunbeds. Meanwhile, use hats and physical protection when outdoors for extended periods. As a result, sun protection is a non-negotiable part of retinoid treatment.
Don't use on broken or sunburned skin
Meanwhile, do not apply to broken, sunburned, or actively inflamed skin. Additionally, tretinoin will make any existing irritation significantly worse. Furthermore, wait until the skin has fully recovered before restarting treatment. Above all, if you develop persistent irritation, pause treatment and contact your prescriber.
Rosacea and eczema
Patients with active rosacea or eczema should approach retinoid treatment cautiously. In particular, 0.01% is the appropriate starting strength for these skin types when treatment is indicated. Meanwhile, some patients with rosacea find even 0.01% too active. Additionally, discuss any inflammatory skin condition during consultation.
Off-label considerations
Compounded tretinoin at 0.01% is an unlicensed special. Firstly, no standard licensed product exists at this strength in the UK. Additionally, off-label prescribing is legal and appropriate when clinically justified. Meanwhile, your prescriber will explain the reasoning, evidence, and alternatives during consultation.
Side effects of Gro Skin Tretinoin 0.01% Cream
Common side effects
Common side effects include mild dryness, tightness, fine flaking, and slight redness during retinisation. Meanwhile, these effects are milder at 0.01% than at higher strengths but not absent. Additionally, they typically settle over 4 to 12 weeks as the skin adapts. As a result, moisturising after tretinoin and building up frequency slowly reduces these effects.
Uncommon side effects
Uncommon side effects include stinging on application, temporary purging of underlying spots, and mild post-inflammatory pigmentation in darker skin tones. Furthermore, purging usually settles within 6 to 8 weeks. Additionally, if pigmentation appears, contact your prescriber for advice.
Rare side effects
Rare side effects include allergic contact dermatitis and marked photosensitivity reactions with unprotected sun exposure. Meanwhile, discontinue if a widespread rash develops. Above all, seek advice if the skin becomes significantly worse after starting treatment.
When to seek advice
Seek advice for persistent burning or stinging, significant peeling that doesn't settle, widespread rash, or new pigmentation changes. Additionally, discontinue and contact your prescriber if you develop any allergic reaction. Above all, don't push through severe irritation. It's a signal to pause and review.
Yellow Card reporting
You can report any suspected side effects directly via the MHRA Yellow Card Scheme at https://yellowcard.mhra.gov.uk. Reporting side effects helps provide more information on the safety of this medicine.
Drug interactions and compatibility with Gro Skin Tretinoin 0.01% Cream
Other topical actives
Firstly, avoid using tretinoin on the same night as AHAs (glycolic, lactic acid), BHAs (salicylic acid), or benzoyl peroxide. Additionally, these combinations increase irritation without adding benefit. Meanwhile, use those actives on non-tretinoin nights or wait for retinisation to complete before layering.
Other prescription topicals
Meanwhile, tell your prescriber about any other topical prescriptions you use, including topical steroids or topical antibiotics. In particular, layering multiple actives on sensitive skin needs careful sequencing. As a result, your prescriber can help you build a routine that works together.
Cosmetic products
Additionally, some cosmetic products can increase irritation with tretinoin. In particular, this includes exfoliating cleansers, alcohol-heavy toners, and physical scrubs. Meanwhile, switch to gentle, non-foaming cleansers during retinisation. Above all, keep the routine simple while your skin adapts.
Gro Skin Tretinoin 0.01% Cream: FAQs
What is tretinoin?
Tretinoin is a vitamin A derivative used topically for skin renewal. In particular, it speeds cell turnover and stimulates collagen production. Meanwhile, it's the most extensively studied topical retinoid in dermatology. Additionally, at 0.01% it's the gentlest strength in the Gro Skin range.
Why start at 0.01% instead of 0.025%?
0.01% is the gentlest starting strength. In particular, it suits patients with very sensitive skin, first-time retinoid users, or those who reacted badly to 0.025%. Meanwhile, most patients can move up the ladder once their skin has adapted. As a result, starting low means treatment gets a real chance rather than being abandoned in the first month.
How long does it take to see results?
You may notice slight smoothness within 4 to 6 weeks. However, visible changes to fine lines and tone usually take 3 to 6 months. Meanwhile, collagen changes continue for well over a year of consistent use. Additionally, at 0.01% the timeline may be slightly slower than at 0.025%.
Why is the shelf life only 30 days?
Tretinoin degrades on exposure to light, air, and heat. Firstly, this is well-established chemistry. Additionally, older jars contain less active than the label states. Meanwhile, APC Labs compounds each tube fresh to order. As a result, using it within 30 days means you get what's on the label from start to finish.
Should I moisturise before or after?
Apply moisturiser after tretinoin, waiting 10 to 15 minutes for the tretinoin to absorb. Meanwhile, some patients apply moisturiser both before and after (the sandwich technique) to reduce irritation. Additionally, either approach is fine at 0.01%. As a result, do what your skin tolerates best.
Can I use tretinoin during pregnancy?
No. Topical tretinoin is avoided during pregnancy and while planning pregnancy. Meanwhile, systemic absorption is low but the theoretical risk means it's not used in these situations. Additionally, discuss safer alternatives with your prescriber if pregnancy is a possibility.
Do I really need SPF every day?
Yes. Tretinoin makes your skin more sensitive to UV. Firstly, unprotected sun exposure while using tretinoin will undo the benefits. Additionally, it increases risk of pigmentation and photoageing. Meanwhile, use SPF 30 or higher daily during treatment, even on cloudy days.
Can I use it around my eyes?
Approach with care. Firstly, the skin around the eyes is thinner and more sensitive. Additionally, apply only a very small amount if using near the orbital area. Meanwhile, keep it away from the immediate eyelid and lash line. As a result, your prescriber can advise if you have specific concerns about the eye area.
What's the difference between tretinoin and retinol?
Tretinoin is prescription-strength retinoic acid. Meanwhile, retinol is an over-the-counter precursor that the skin converts to retinoic acid. In particular, retinol is much weaker and slower-acting than tretinoin. As a result, tretinoin at 0.01% is stronger than most retinol products despite being the gentlest prescription strength.
Can I combine tretinoin with niacinamide?
Yes. Niacinamide pairs well with tretinoin and can reduce irritation. In particular, the Gro Skin range includes combination creams that bring both into a single formulation. Meanwhile, if using them separately, apply niacinamide first, wait a few minutes, then apply tretinoin. Additionally, or use them on alternating days.
Can I combine tretinoin with vitamin C?
Yes, but not at the same time of day. Firstly, use vitamin C serum in the morning under sunscreen. Additionally, use tretinoin at night. Meanwhile, keeping them apart avoids irritation and gives both actives the best chance to work.
How can I minimise dryness and peeling?
Firstly, build up frequency slowly (every third night, then every other, then nightly). Additionally, always moisturise after tretinoin. Meanwhile, use gentle non-foaming cleansers. Furthermore, avoid other actives during retinisation. As a result, most patients find the initial adjustment period is milder than they expected.
Should I stop using tretinoin during winter?
Not necessarily. Meanwhile, cold and central heating can dry the skin, so some patients reduce frequency during winter. Additionally, others use richer moisturisers. Above all, consistency matters year-round for tretinoin to work.
What if I miss a night?
Just resume at the next scheduled night. Firstly, don't apply extra to make up for it. Additionally, don't apply two nights in a row if you missed a night, unless you're already on nightly use. Meanwhile, consistency over months matters far more than any single missed night.
Can I move up to 0.025% eventually?
Possibly. In particular, if your skin adapts well to 0.01% and your prescriber agrees that a stronger strength is appropriate, you can move up the ladder. Meanwhile, some patients stay at 0.01% long-term because it delivers everything they need. Additionally, the ladder allows for both directions.
Is Gro Skin Tretinoin 0.01% Cream licensed?
No. This specific compounded strength is an unlicensed special. Meanwhile, no fixed-strength tretinoin at 0.01% carries a UK marketing authorisation. Additionally, unlicensed does not mean unregulated. As a result, APC Labs compounds under GPhC regulation and the prescriber decides suitability.
Can I use it if I have rosacea?
Cautiously. In particular, some rosacea patients tolerate 0.01% well. Meanwhile, others find even this strength too active. Additionally, discuss your rosacea history in detail during consultation. Above all, be prepared to stop if flushing or redness worsens.
Will it help with acne?
Possibly. Tretinoin is licensed for acne at higher strengths (0.025% and above). Meanwhile, at 0.01% the anti-acne effect is milder. Additionally, if acne is your primary concern, your prescriber may recommend a higher Gro Skin ladder strength or a different active. As a result, discuss your main concern during consultation.
How much cream should I use?
A pea-sized amount for the whole face is enough. Meanwhile, using more does not give better results and increases irritation. Additionally, if you're only treating specific areas, use even less. Above all, tretinoin follows the less-is-more principle.
Will I need a prescription from Courier Pharmacy?
Yes. Gro Skin Tretinoin 0.01% Cream is a Prescription Only Medicine. Meanwhile, our partner prescriber Majad Mahroof (GPhC 2049335) or another UK-qualified prescriber reviews every request. Additionally, you can complete the consultation at courierpharmacy.co.uk.
