Ever wondered why two skin creams from the same vitamin A family can feel so different on your face? When it comes to adapalene vs tretinoin, one is the gentle newcomer and the other is the seasoned heavyweight, and choosing between them is less about “which is better” and more about which one your skin will actually get along with.
If you’ve been reading about retinoids online, you’ve probably seen both names crop up. Maybe a friend swears by tretinoin. Perhaps your GP mentioned an adapalene gel. And then there’s TikTok, where everyone seems to have a strong opinion and a ring light.
Here’s the thing. Most of what you’ll find was written for American readers. It talks about buying adapalene off the shelf and quotes brands you can’t get here. That’s not much use if you live in Leeds or Llandudno.
So in this guide, our pharmacists walk you through the real difference between adapalene and tretinoin. We’ll look at how each one works, what the research says for acne and ageing, and how irritating each tends to be. We’ll also cover what’s actually available in the UK, who should avoid them, and how to decide which suits you.
One quick note before we start. Both are prescription-only medicines in the UK, and neither should be used in pregnancy. Nothing here replaces a proper assessment.
Five key takeaways
- Adapalene and tretinoin are both topical retinoids, but they’re different medicines. Tretinoin is a natural form of vitamin A acid, while adapalene is a lab-designed retinoid built to be gentler.
- For acne, head-to-head trials found adapalene 0.1% works about as well as tretinoin 0.025%, with less redness, peeling and stinging.
- For wrinkles and sun damage, tretinoin has decades more research behind it. Adapalene shows promise, but the evidence is smaller.
- In the UK, both need a prescription. Licensed tretinoin only comes combined with an antibiotic, so plain tretinoin is supplied as an unlicensed or compounded medicine.
- Neither should be used in pregnancy or while trying for a baby, and daily SPF 30 or higher is part of the treatment with both.
Adapalene vs tretinoin at a glance
Is adapalene the same as tretinoin? No. They belong to the same family and do similar jobs, but they’re chemically different. Think of them as cousins rather than twins. Here’s a quick side-by-side.
| Adapalene | Tretinoin | |
| What it is | Synthetic third-generation retinoid | Natural first-generation retinoid (all-trans retinoic acid) |
| Main UK use | Acne | Acne (licensed); ageing and pigmentation (off-label) |
| Common strengths | 0.1% alone; 0.1% or 0.3% with benzoyl peroxide | 0.01% to 0.1% worldwide; 0.025% in UK licensed products |
| Irritation | Usually milder | Usually more noticeable, especially early on |
| Stable in light? | Yes | No, it breaks down in sunlight |
| UK status | Prescription-only | Prescription-only |
| Pregnancy | Avoid | Avoid |
The short version? Adapalene tends to be the easier ride. Tretinoin tends to be the stronger all-rounder, especially for ageing skin.
What is tretinoin?
The original retinoid
Tretinoin is all-trans retinoic acid, the active form of vitamin A that your skin cells respond to directly. It’s been used on skin for more than fifty years, which in medicine makes it something of a national treasure.
Because it’s already in its active form, tretinoin doesn’t need converting by your skin first. That’s why it’s far more potent than the retinol in shop-bought serums. We explain that difference in more detail in our guide to which tretinoin strength to use.
What tretinoin is used for
Tretinoin speeds up how quickly skin cells are made and shed. That stops dead cells clumping together inside pores, which is how blackheads and whiteheads begin. It also calms inflammation.
Over months, it nudges the deeper layers of skin to build more collagen. That’s why it’s so popular for fine lines, rough texture and uneven tone. In the UK, though, it’s only licensed for acne. Using it for ageing is off-label, which a prescriber can still choose to do. Our article on how tretinoin fights the signs of ageing covers this in depth.
What is adapalene?
A retinoid designed to be gentler
Adapalene arrived in the 1990s. Scientists developed it to keep the acne-clearing benefits of tretinoin while cutting down the irritation that made so many people give up. It’s often called a third-generation retinoid.
Here’s a simple way to picture it. If tretinoin is a classic sports car, powerful but a bit of a bumpy ride, adapalene is the modern hybrid. It gets you to the same place for most acne journeys, just with better suspension.
What adapalene is used for
Adapalene is licensed in the UK for acne, particularly where there are blackheads, whiteheads and red spots on the face, chest or back. You’ll find it on its own as Differin, or combined with benzoyl peroxide in gels such as Epiduo.
Some prescribers also use it off-label for things like keratosis pilaris and mild sun damage. However, its main job is keeping pores clear.
How adapalene and tretinoin work in your skin
A lock-and-key story
Both medicines work by switching on retinoic acid receptors inside your skin cells. You can think of these receptors as locks on the doors of your cells. When the right key turns, the cell changes how it grows and sheds.
Your skin has three main types of these locks, called alpha, beta and gamma. Tretinoin is a master key that fits all three. Adapalene is more selective, mainly fitting the beta and gamma locks. The gamma lock is the one that matters most for acne.
That selectivity is a big part of the difference between adapalene and tretinoin. Because adapalene doesn’t rattle every door in the building, it tends to cause less irritation while still doing the acne-clearing work.
Why light and benzoyl peroxide matter
There’s a practical difference too. Tretinoin breaks down when exposed to sunlight, which is one reason it’s applied at night. Older tretinoin formulations can also be broken down by benzoyl peroxide, so prescribers often suggest using them at different times of day.
Adapalene, by contrast, holds up well against light and oxygen and is chemically quite unreactive. That stability is exactly why it can be paired with benzoyl peroxide in a single gel. For many people, one tube instead of two makes a routine much easier to stick to.
Adapalene vs tretinoin for acne: what the evidence says
Head-to-head trials
This is where adapalene really earns its place. Researchers have compared the two directly in several large trials.
A review of three large, well-run studies involving nearly 900 patients found adapalene 0.1% gel and solution were at least as effective as tretinoin 0.025% gel, and better tolerated. A pooled analysis also suggested adapalene started working sooner.
The tolerability gap shows up clearly in the numbers. In a combined analysis of two 12-week trials with nearly 600 people, about 5% of the adapalene group reported side effects compared with about 9% of the tretinoin group. Roughly half as many people on adapalene stopped treatment because of side effects.
What about stronger tretinoin? A 12-week trial of 168 people compared adapalene 0.1% with a 0.1% tretinoin microsphere gel. Both cleared acne to a similar degree and started working at a similar pace, but skin tolerance scores were notably better with adapalene.
So for acne, adapalene vs tretinoin is closer to a draw on results. Adapalene usually wins on comfort.
What UK guidance recommends
NICE, which sets treatment standards for England and Wales, includes both medicines among its first-line options. Its acne guideline recommends a 12-week course of options including adapalene combined with benzoyl peroxide for any severity, or tretinoin combined with clindamycin for any severity.
NICE also flags that topical adapalene and benzoyl peroxide can cause irritation, sun sensitivity, and bleaching of hair and fabrics. So, a tip from experience: switch to white pillowcases. Your favourite navy set will thank you.
If your acne includes deep, painful lumps or is leaving scars, a cream alone may not be enough. See your GP, as you may need tablets or a specialist referral. Our acne page explains the wider options.
Adapalene vs tretinoin for ageing and sun damage
Here, tretinoin is the clear frontrunner. It has decades of research, including studies looking at skin under the microscope. In one well-known 48-week trial, both tretinoin 0.025% and 0.1% tretinoin improved sun-damaged skin by a similar amount. The higher strength simply caused more redness and peeling.
Adapalene’s anti-ageing evidence is younger and smaller. A randomised trial found adapalene gel improved sun spots and rough patches over several months. A later Brazilian study compared adapalene 0.3% with tretinoin 0.05% cream and found broadly similar improvements in photoaged skin.
That’s encouraging, especially for people whose skin won’t tolerate tretinoin. Even so, if fine lines are your main goal, tretinoin has the longer track record. In the UK, both uses are off-label, so your prescriber should explain this to you.
A word on dark marks. Irritated skin can make extra pigment, particularly in deeper skin tones. So the gentler option sometimes wins for pigmentation, simply because it causes less inflammation. Our guide to skin hyperpigmentation explains why, and our article on how tretinoin for scars works covers post-acne marks.
Side effects and irritation
What to expect in the first few weeks
Both medicines can cause dryness, tightness, flaking, redness and a stinging feeling, especially at the start. Your skin may also burn more easily in the sun. These effects usually peak in the first month and then settle as your skin adjusts.
With either one, spots can flare briefly before they improve. People often call this the purge. It happens because the medicine speeds up skin turnover, pushing blocked pores to the surface faster. Annoying? Yes. A sign it’s not working? Usually not.
In our experience, the people who do best are the ones who expect this phase and plan for it. The ones who quit in week three often do so because nobody warned them.
Practical tips to keep your skin on side
- Start slowly. Many prescribers suggest two or three nights a week at first, building up as your skin allows.
- Use a pea-sized amount for your whole face. More product won’t work faster, it’ll just irritate more.
- Apply to clean, fully dry skin. The NHS suggests waiting around 20 minutes after washing.
- Keep it away from your eyes, lips, nostrils and the corners of your mouth.
- Add a simple, fragrance-free moisturiser. It won’t stop the medicine working.
- Wear SPF 30 or higher every morning, even on a drizzly Tuesday in Derby.
- Pause scrubs, peels and strong acids while your skin settles.
Our step-by-step guide on how to apply tretinoin cream works well for adapalene too, as long as you follow the directions on your own label.
If you get burning that won’t ease, swelling, cracked skin or a spreading rash, stop and speak to your prescriber. You can also report side effects through the MHRA’s Yellow Card scheme.
Adapalene vs tretinoin in the UK: what you can actually get
Licensed adapalene products
In the UK, adapalene 0.1% is available on its own as a gel or cream. You’ll also find it combined with benzoyl peroxide 2.5%, at either 0.1% or 0.3% adapalene. All of these are prescription-only.
That surprises a lot of people. In the US, adapalene 0.1% gel has been sold over the counter since 2016. Here, you’ll still need a prescriber to assess you first.
Licensed tretinoin products
The UK picture for tretinoin is narrower. The only licensed tretinoin skin products here are Treclin gel, which contains tretinoin 0.025% with clindamycin 1%, and Aknemycin Plus solution, which pairs tretinoin 0.025% with erythromycin 4%. Both are for acne.
That’s fine if you have acne and an antibiotic suits you. But if you want tretinoin on its own, at a different strength, or for ageing skin, there’s no licensed option.
Plain tretinoin and compounding at Courier
When a prescriber decides plain tretinoin is right for you, it’s supplied as an unlicensed medicine. That means either an imported product or one prepared by a registered pharmacy for you as a named patient.
Unlicensed doesn’t mean illegal or unregulated. It means the MHRA hasn’t assessed that finished product in the way it would a licensed one. Your prescriber should explain this before anything is supplied.
Courier is a compounding pharmacy, so where it’s clinically appropriate, we can prepare tretinoin creams in a range of strengths, tailored to the person rather than the shelf.
One more thing. If a website offers to post either medicine to you without asking about your health, close the tab. A genuine UK pharmacy will always assess you first.
Compounding at Courier
When the standard option isn’t the right fit, we can make one to order
Courier is a compounding pharmacy. Where a prescriber decides it’s appropriate for you, we can prepare bespoke, made-to-order preparations — tailored to the individual, under full clinical governance. It’s the same principle that runs through everything we do.
Which is right for you?
Sensitive or first-time retinoid users
There’s no universal winner in the adapalene vs tretinoin debate. The better choice depends on your skin, your goals and how much irritation you’re willing to put up with. Here are three common situations we see.
Say you’re 19, with blackheads and a few angry spots on your chin, and your skin goes red if you look at it funny. Adapalene, often combined with benzoyl peroxide, is usually a sensible starting point. It’s gentle, well studied for acne and simple to use.
Acne plus early signs of ageing
Now picture someone in their early thirties with occasional breakouts, a few fine lines and some leftover marks. Tretinoin may make more sense here, because it tackles acne and ageing with one product. Starting low, around tretinoin 0.025%, keeps irritation manageable.
Mainly wrinkles, sun damage or texture
For someone in their forties or fifties focused on fine lines and rough texture, tretinoin has the strongest evidence. If their skin really can’t cope, adapalene is a reasonable alternative worth discussing.
Your prescriber will also think about your medical history, other medicines and any plans for pregnancy. That’s why a proper consultation matters more than any online quiz.
Who should avoid adapalene and tretinoin?
Neither medicine is right for everyone. Speak to a prescriber first if any of these apply.
- Pregnancy or trying for a baby. The Differin leaflet for professionals says it must not be used in pregnancy or by women planning one, and treatment should stop if pregnancy occurs. Tretinoin is avoided for the same reason. Only tiny amounts pass through the skin, but the risk can’t be ruled out.
- Breastfeeding. Very little adapalene reaches the bloodstream, but it shouldn’t be applied to the chest while breastfeeding. Tretinoin isn’t recommended. Ask your prescriber about safer options.
- Children. Age limits vary by product, so check the leaflet. Treclin, for example, is licensed from 12.
- Eczema, rosacea or perioral dermatitis. Retinoids can make these worse.
- Sunburnt, broken or freshly waxed skin. Wait until it has fully healed.
- Sunbeds and sun lamps. Avoid them while using either medicine.
Also tell anyone giving you facial waxing, peels or laser treatments that you’re using a retinoid. Skin on retinoids can be more fragile.
Can you switch between them?
Yes, and plenty of people do. Someone might start on adapalene, get their acne under control, and later move to tretinoin for ageing. Others go the other way after finding tretinoin too harsh.
The key is to switch, not stack. Using both at once doubles the irritation without doubling the benefit. When you change, it’s usually wise to drop back to a few nights a week and build up again.
Frequently asked questions about adapalene vs tretinoin
What is the main difference between adapalene and tretinoin?
The main difference between adapalene and tretinoin is how selective they are. Tretinoin switches on all three types of retinoid receptor in the skin. Adapalene targets mainly one or two, which usually makes it gentler while still clearing acne.
Is adapalene the same as tretinoin?
No. Adapalene is a synthetic retinoid, while tretinoin is a natural form of vitamin A acid. They work in similar ways, but they’re different medicines with different side effect profiles.
Which is better for acne, adapalene or tretinoin?
In head-to-head trials, adapalene 0.1% cleared acne about as well as tretinoin 0.025%, with less irritation. Both are NICE first-line options in combination products, so the best choice depends on your skin.
Which is better for wrinkles, adapalene or tretinoin?
Tretinoin has much more evidence for wrinkles and sun damage. Adapalene has shown promise in smaller studies, so it can be an option if tretinoin is too irritating. Both uses are off-label in the UK.
Is tretinoin stronger than adapalene?
Generally, yes. Tretinoin acts on more receptors and tends to cause more irritation. However, stronger doesn’t always mean better results, especially for acne, where adapalene performs similarly.
Can I buy adapalene or tretinoin over the counter in the UK?
No. Unlike in the US, both are prescription-only medicines in the UK. You’ll need an assessment from a GP, dermatologist or pharmacist prescriber.
Can I use adapalene and tretinoin together?
It’s not usually recommended. Using two retinoids at once increases dryness and irritation without adding much benefit. Pick one, and switch rather than combine if you need a change.
Do adapalene and tretinoin cause purging?
Both can cause a temporary flare of spots in the first few weeks. This happens because skin turnover speeds up. It usually settles within a month or two.
How long do adapalene and tretinoin take to work?
Most people see changes in acne after 8 to 12 weeks of regular use. NICE suggests reviewing acne treatment at 12 weeks. Improvements in fine lines take longer, often several months.
Can I use adapalene or tretinoin while pregnant?
No. Both should be avoided during pregnancy and while trying to conceive. If you become pregnant while using either, stop and speak to your prescriber.
