Buying Tretinoin in Thailand: OTC Prices, Brands & Where to Go (2026)

TL;DR

Tretinoin is sold over the counter in Thailand — but only at independent pharmacies. Chain pharmacies like Boots and Watsons officially require a prescription and rarely stock it. In Bangkok, head to independent pharmacies on Sukhumvit Road, in Silom/Sathorn, or near Khao San Road and ask for tretinoin or "Retin-A". Expect $2-3 for Thai-made Acnetin-A (10g), $3-5 for Stieva-A (25g), and $8-15 for international brands like Retin-A or Retacnyl. Thailand has the widest tretinoin brand selection in Southeast Asia.

Is Tretinoin Over the Counter in Thailand?

Yes — with one big caveat. Tretinoin availability in Thailand depends entirely on the type of pharmacy. Independent pharmacies sell it over the counter without a prescription; chain pharmacies follow stricter internal guidelines and usually won't.

Pharmacy Type	Sells Tretinoin OTC?	Notes
Independent pharmacies	Yes, usually	Best bet — tourist-area pharmacies are used to Western buyers
Boots / Watsons (chains)	No	Officially prescription-only; rarely on shelves at all
Hospital pharmacies	With prescription	Reliable stock but requires a doctor visit

Some independent pharmacists will still ask questions or occasionally refuse — it varies shop to shop. If one says no, the next one down the street usually says yes. This is the main practical difference from Cambodia, where buying is friction-free.

Where to Buy Tretinoin in Bangkok

Independent pharmacies on Sukhumvit Road: Best bet. Walk in, ask for tretinoin or 'Retin-A'. Most will sell without prescription.
Pharmacies near Khao San Road: Tourist-oriented, accustomed to Western buyers. Slightly higher prices.
Silom/Sathorn area pharmacies: Mix of chains and independents. Try the smaller shops.
Avoid: Boots, Watsons, and other chain pharmacies — they follow stricter guidelines and are unlikely to sell OTC.

The same chain-vs-independent rule applies outside Bangkok: in Chiang Mai, Phuket, Pattaya, or Hatyai, look for the small independent pharmacies rather than mall chains. Hatyai in southern Thailand is a popular pharmacy run for Malaysians, since tretinoin is prescription-only across the border in Malaysia.

Tretinoin Brands & Prices in Thailand

Thailand has the widest variety of tretinoin brands in Southeast Asia and some of the cheapest generics — Bangkok pharmacies stock everything from Thai-manufactured Acnetin-A to Korean formulations you won't find elsewhere in the region.

Brand	Origin	Strengths	Typical Price
Acnetin-A	Thailand	0.025%, 0.05%	$2-3 (10g)
Stieva-A (GSK)	Thailand	0.025%, 0.05%, 0.1%	$3-5 (25g)
Retin-A (Johnson & Johnson)	Various	0.05%	$8-12 (20g)
Retacnyl (Galderma)	France	0.05%	$12-15 (30g)

Looking for 0.1%?

Stieva-A is the most commonly stocked brand that goes up to 0.1% strength. Ask for it by name. If you've never used tretinoin before, don't start at 0.1% — start at 0.025% and work up (see our tretinoin strength guide).

Acnetin-A: The Thai Workhorse

Acnetin-A is Thailand's own generic tretinoin and the cheapest reliable option at $2-3 for a 10g tube. It's widely exported around the region — it's the same tube you'll find in Phnom Penh and Ho Chi Minh City pharmacies, usually at a small markup. Available in 0.025% and 0.05%.

Thailand vs Cambodia vs Vietnam

	Thailand	Cambodia	Vietnam
Prescription needed?	No (independents)	No	No
Ease of buying	Easy (varies by pharmacy)	Very easy	Moderate (language barrier)
English spoken	Yes (tourist areas)	Yes (major pharmacies)	Limited
Price range (generic)	$2-5	$2.50-4	$2-4
Price range (premium)	$8-15	$15-20	$5-8
Brand selection	Best	Good	Good

Thailand wins on brand selection and generic prices; Cambodia wins on ease; Vietnam wins on rock-bottom prices. If you're doing a multi-country Southeast Asia trip, any of the three works — see the full Southeast Asia tretinoin comparison.

Practical Tips for Buying in Thailand

Ask for 'tretinoin' or 'Retin-A' — both names are understood at tourist-area pharmacies.
Start with 0.025% if you've never used tretinoin. Apply every 2-3 nights for the first month.
Store it in the fridge. Thailand is hot and tretinoin degrades in heat — buy from air-conditioned pharmacies and refrigerate at your hotel.
Check the expiry date before paying. High-turnover pharmacies have fresh stock.
Apply at night only and wear SPF 50+ the next day. Tretinoin plus tropical sun is a bad combination.
Bring it home in original packaging. US, UK, EU, and Australian customs generally allow personal-use quantities (6-12 tubes).

Frequently Asked Questions

Can you buy tretinoin over the counter in Thailand?

Yes, at independent pharmacies. Chain pharmacies (Boots, Watsons) typically require a prescription and rarely stock it. Independent pharmacies in Bangkok tourist areas like Sukhumvit, Silom, and Khao San sell it openly for $2-15 per tube.

How much does tretinoin cost in Thailand?

Thai-made generics are the cheapest: Acnetin-A runs $2-3 for a 10g tube and Stieva-A $3-5 for 25g. International brands cost more — Retin-A around $8-12 and Retacnyl $12-15. Prices are slightly higher at tourist-area pharmacies.

Where can I buy tretinoin 0.1% in Thailand?

Ask for Stieva-A, which is stocked in 0.025%, 0.05%, and 0.1% strengths at independent pharmacies. Acnetin-A only goes up to 0.05%. Only use 0.1% if you're an experienced tretinoin user.

Do Boots or Watsons in Thailand sell tretinoin?

No — chain pharmacies follow stricter guidelines, officially require a prescription, and rarely have tretinoin on the shelf. Buy from independent pharmacies instead.

Is Acnetin-A the same as tretinoin?

Yes. Acnetin-A is a Thai-manufactured tretinoin generic, available in 0.025% and 0.05% strengths. The active ingredient is identical to prescription tretinoin sold in Western countries — only the regulatory classification differs.

Can I bring tretinoin home from Thailand?

Most customs agencies (US, UK, EU, Canada, Australia) allow reasonable personal-use quantities — typically up to 90 days' supply, around 10-12 tubes. Keep it in original packaging and declare it if asked.

Is tretinoin from Thailand safe and genuine?

Buying from licensed brick-and-mortar pharmacies in Thailand is the safe route — brands like Acnetin-A, Stieva-A, and Retacnyl are legitimate manufactured pharmaceuticals. The risks are with street markets and unverified online sellers, not licensed pharmacies. Check expiry dates and avoid tubes that have clearly sat in the heat.

Comparing Countries for Your Trip?

Cambodia is the easiest country in Southeast Asia for OTC tretinoin — English-speaking pharmacies, no pharmacist gatekeeping, and prices from $2.50 per tube.
