Key takeaways
Adapalene is a topical retinoid and a first-line treatment for mild-to-moderate acne: it unclogs pores and calms inflammation rather than masking spots.
In head-to-head trials it matched or beat tretinoin 0.025% while causing significantly less dryness and irritation, which is why doctors usually start with it.
In Thailand it is pharmacist-dispensed. Menscape does not keep it on the shelf: it is stocked on request after a pharmacist or doctor checks it suits your skin.
Results take 8–12 weeks of nightly use, and skin often looks slightly worse in weeks 2–4 before it looks better. That phase is normal and passes.
01
What adapalene is & how it works
Adapalene is a topical retinoid used to treat acne: the blackheads, whiteheads and inflamed spots that block pores on the face, chest and back. Dermatology guidelines list topical retinoids as first-line treatment for almost every grade of acne,⁴ and adapalene is usually the one doctors reach for first because it is the gentlest of the class.
Acne starts inside the pore. Dead skin cells stick together with oil and block the follicle; bacteria multiply behind the blockage and the spot turns red and sore. Adapalene binds to retinoid receptors in the skin and normalises how cells turn over inside the pore, so existing blockages clear and new ones form less often. It also has a direct anti-inflammatory effect, which is why it helps angry red acne and not just blackheads.⁶
It is a treatment you commit to, not a spot cream. Skin often looks slightly worse in the first 2–4 weeks, results show at 8–12, and stopping early is the most common reason it "fails". A pharmacist or doctor can tell you whether adapalene alone is enough, or whether it should be paired with benzoyl peroxide or stepped up to something stronger.
A pore blocks
Dead skin cells and oil stick together inside the follicle, forming the microcomedone that every spot starts from.
Adapalene resets cell turnover
It binds retinoid receptors in the skin and normalises how cells shed inside the pore.⁶
Blockages clear
Existing comedones lift out and new ones form less often, so blackheads and whiteheads thin out over weeks.
Inflammation cools
Adapalene also damps the skin's inflammatory response, shrinking the red, sore spots.⁶

Getting adapalene in Thailand
Thai FDA status
Registered with the Thai FDA and classified as a dangerous drug (ยาอันตราย): a licensed pharmacist can dispense the 0.1% strength without a doctor's prescription. Both the original brand and registered generics are sold in Thai pharmacies.⁷
How to get it through Menscape
Menscape does not keep adapalene on the shelf. It is stocked on request: message the clinic or walk in, a pharmacist or doctor checks it actually suits your skin, and the product is ordered in for pickup or delivery.
Buy from a licensed source
Adapalene is easy to find in licensed Bangkok pharmacies, which makes the grey market pointless. Marketplace sellers offering unmarked tubes or "stronger" retinoids carry counterfeit and storage-damage risks, with nobody accountable for what arrives.
Thai FDA warning. The regulator has repeatedly warned against buying medicines from unlicensed online sellers. A licensed pharmacy or clinic is accountable for what it dispenses; a marketplace seller is not.
03
Does it work? The evidence
Adapalene has one of the deeper evidence bases in acne care. In a randomised 12-week trial of 323 patients, adapalene 0.1% gel reduced total lesion counts by 49%, versus 37% with tretinoin 0.025% gel, and caused significantly less dryness and irritation.² Multicentre comparisons in Europe and the US repeated the pattern: equal or better clearance, better tolerability.³ US dermatology guidelines list topical retinoids as first-line for nearly all acne.⁴
Two honest caveats. First, timelines: lesion counts fall steadily over 8–12 weeks, and skin can look slightly worse in weeks 2–4 before it looks better. Second, scope: adapalene alone suits mild-to-moderate acne. For more inflamed or widespread acne, combining it with benzoyl peroxide clears significantly more lesions than either alone,⁵ and severe nodular acne needs a doctor, not a shelf product.

Side effects & who shouldn't take it
Common side effects
Dryness, peeling, redness and mild stinging or burning where it is applied. This peaks in weeks 2–4 as the skin adjusts, then settles. A plain moisturiser and starting every other night make most of it manageable.
When to stop and get reviewed
Severe redness, swelling, blistering or crusting is not normal adjustment: stop and see a doctor. True allergic contact reactions to adapalene are rare but documented.
Not suitable for
Broken, sunburned or eczema-affected skin, and anyone with a known allergy to adapalene. Women who are pregnant or trying to conceive should not use it: topical retinoids are avoided in pregnancy as a precaution. Deep, painful nodular acne needs a doctor rather than a retinoid alone.
Interactions & practical warnings
Hold off on strong exfoliants (AHA/BHA acids, scrubs) while your skin adjusts, and skip waxing on treated areas because the skin can tear. Adapalene raises sun sensitivity, so daily sunscreen matters under Bangkok UV. Unlike older retinoids it stays stable alongside benzoyl peroxide, though using both increases dryness.
05
Alternatives & combinations
OTC · often combined
Benzoyl peroxide
An antibacterial wash or gel that kills acne bacteria. Adapalene is chemically stable alongside it, so the two are often used together, and fixed combinations of both exist as a single gel.
Rx · stronger retinoid
Tretinoin
The oldest and most-studied topical retinoid. Comparable results to adapalene in head-to-head trials but harder on the skin, and it degrades in sunlight and next to benzoyl peroxide. A doctor may step up to it if adapalene stalls.
Rx · severe acne
Isotretinoin
The oral retinoid for severe, nodular or scarring acne. Highly effective but needs blood-test monitoring and strict precautions, so it is prescription-only and doctor-managed at the clinic.

Get your skin checked properly today.
Message us or walk in
Send photos of your skin by chat or come to the clinic at Asoke. Tell us what you have already tried and what you currently put on your face.
Skin check first
A pharmacist or doctor confirms it is acne, grades it, and checks a retinoid is the right call. Fungal folliculitis and razor bumps look similar and need different treatment.
Stocked on request
Adapalene is not kept on the shelf. If it suits you, the clinic orders it in for pickup or delivery. Severe or scarring acne is booked with the doctor instead.
How-to-use guidance
You leave knowing the routine: a pea-sized amount at night, moisturiser, morning sunscreen, and what weeks 2–4 will feel like. Check in if your skin is not settling.
The pharmacist and doctor decide. Asking about adapalene is not a purchase; if it is not right for your skin, we will say so and point you to what is.

“Half the men I see have spent years buying acne products at random without ever using a retinoid properly. Adapalene applied nightly for twelve weeks does more than a shelf of cleansers.”

Frequently asked questions
Can I buy adapalene over the counter in Thailand?
More or less. It is classified as a dangerous drug (ยาอันตราย), which means a licensed pharmacist can dispense it without a doctor's prescription. You will find it in most Bangkok pharmacies, and the pharmacist should still check it suits your skin. Unlicensed online sellers remain illegal and a counterfeit risk.
How long until adapalene works?
Plan for 8–12 weeks of nightly use before judging it. Some men see change earlier, but trials measure results at 12 weeks, and quitting at week 4 is the most common way to waste the effort.
Why did my skin get worse when I started?
The first 2–4 weeks often bring dryness, peeling and a flush of new spots as blocked pores clear out. It is a known adjustment phase, not a sign the treatment is failing. Moisturiser and every-other-night use help; if it is severe, stop and get reviewed.
Adapalene vs tretinoin: which should I use?
Head-to-head trials show similar or better results with noticeably less irritation from adapalene, which is why it is the usual starting point. Tretinoin is a reasonable step up if adapalene plateaus, but that is a doctor's call, not a shelf upgrade.
Can I use adapalene with benzoyl peroxide?
Yes. Adapalene is chemically stable next to benzoyl peroxide, unlike tretinoin, and the combination clears more lesions than either alone in trials. Expect more dryness at first; build up slowly.
Do I really need sunscreen with it?
Yes. Adapalene makes skin more sun-sensitive, and Bangkok UV is high year-round. A morning SPF protects your results and stops the dark marks acne leaves behind from getting darker.
Will adapalene fade acne scars and dark marks?
It helps the flat dark marks (post-inflammatory hyperpigmentation) fade over months, and there is evidence of modest improvement in mild atrophic scarring with long-term use. Deep or pitted scars need in-clinic procedures rather than a cream.
Does Menscape have adapalene in stock?
Not on the shelf. It is stocked on request: message the clinic first, a pharmacist or doctor confirms it suits your skin, and it is ordered in for pickup or delivery. Severe or scarring acne goes to the doctor instead.
