TL;DR
Why This Guide Exists
If you're Googling "where to buy tretinoin in Southeast Asia," you already know the deal: tretinoin is the gold standard anti-aging ingredient, and it costs a fortune with a prescription back home. Southeast Asia sells it over the counter for the price of a coffee.
But "Southeast Asia" is three very different experiences depending on where you go. We've bought tretinoin in all three countries and this guide covers the practical differences — not just price, but how easy it actually is to walk in, buy it, and walk out.

Cambodia: Easiest for English Speakers
Cambodia is the most friction-free option. Walk into any major pharmacy in Phnom Penh, ask for tretinoin by name, and pay. No awkward negotiations, no language barriers at the main pharmacies, no pharmacist gatekeeping.
Where to Buy in Phnom Penh
- Ucare Pharmacy (BKK1, Street 51): The default choice. English-speaking staff, air-conditioned, consistent stock. Multiple branches across the city.
- Pharmacie de la Gare (near Central Market): French-run, stocks premium European brands like Retacnyl by Galderma.
- Aeon Mall pharmacies: Convenient, reliable stock of common brands.
Brands & Prices
| Brand | Origin | Strength | Price |
|---|---|---|---|
| Acnetin-A | Thailand | 0.025-0.05% | $2.50-4 (10g) |
| Tretin (H&H) | India | 0.025-0.05% | $8-12 (30g) |
| Retacnyl (Galderma) | France | 0.05% | $15-20 (30g) |
| A-Ret (Menarini) | India | 0.1% | $7-10 (20g) |
Cambodia Bottom Line
Best for: first-time buyers, English speakers, combining with a dermatologist consultation ($40-80 at Phnom Penh clinics). Read our full tretinoin Cambodia guide for pharmacy-by-pharmacy details.
Thailand: Best Brand Selection
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.
The catch: it depends on the pharmacy. Chain pharmacies like Boots and Watsons officially require a prescription (they rarely have tretinoin on shelves). Independent pharmacies in tourist areas (Sukhumvit, Silom, Khao San) are where you buy OTC — but some pharmacists will ask questions or refuse.
Where to Buy 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.
Brands & Prices
| Brand | Origin | Strength | Price |
|---|---|---|---|
| Acnetin-A | Thailand | 0.025-0.05% | $2-3 (10g) |
| Stieva-A (GSK) | Thailand | 0.025-0.1% | $3-5 (25g) |
| Retacnyl (Galderma) | France | 0.05% | $12-15 (30g) |
| Retin-A (Johnson & Johnson) | Various | 0.05% | $8-12 (20g) |
Thailand Bottom Line
Best for: brand-conscious buyers, those already visiting Bangkok, people who want the widest selection. Slightly more effort than Cambodia due to pharmacy variability.
Vietnam: Cheapest Overall
Vietnam edges out Cambodia and Thailand on pure price — generics can be as low as $2 for a tube. Ho Chi Minh City and Hanoi both have pharmacies that sell tretinoin over the counter without hesitation.
The challenge is language. Outside of tourist districts, English is limited in Vietnamese pharmacies. Know the brand name or bring a picture of what you want. The Google Translate camera feature is your friend here.
Where to Buy in Ho Chi Minh City
- Pharmacies on Hai Ba Trung Street (District 1): Tourist-accessible, some English spoken. Ask for tretinoin or show the brand name on your phone.
- Pharmacity / Long Chau chains: Vietnam's pharmacy chains. Stock is consistent, but staff English is limited.
- Hospital pharmacies: Reliable stock, often cheaper, but require navigating hospital complexes.
Where to Buy in Hanoi
- Pharmacies in the Old Quarter: Most accessible for tourists. Higher prices than local areas.
- Ba Dinh district pharmacies: Local prices, less English.
Brands & Prices
| Brand | Origin | Strength | Price |
|---|---|---|---|
| Tretinoin (local generics) | Vietnam | 0.025-0.05% | $2-3 (10g) |
| Acnetin-A | Thailand | 0.025-0.05% | $3-4 (10g) |
| Retin-A | Various | 0.05% | $5-8 (20g) |
Vietnam Bottom Line
Best for: budget buyers, those already visiting Vietnam, people comfortable navigating language barriers. Cheapest prices but least convenient experience.
Which Country Should You Choose?
| If you... | Go to |
|---|---|
| Want the easiest experience | Cambodia |
| Want the cheapest price | Vietnam |
| Want the most brand options | Thailand |
| Speak only English | Cambodia |
| Are combining with a skin consultation | Cambodia (cheapest derm consultations) |
| Are already on a SE Asia trip | Whichever country you're in — all work |
| Want to stock up (10+ tubes) | Cambodia or Vietnam (least hassle for bulk) |
Price Comparison: SE Asia vs Western Countries
The real comparison that matters — what you'd pay at home vs here.
| Country | Generic Tretinoin | Prescription Required? |
|---|---|---|
| Cambodia | $3-15 | No |
| Thailand | $2-8 | No |
| Vietnam | $2-5 | No |
| Singapore | $25-50 | Yes |
| Australia | $40-80 | Yes |
| UK | $50-100+ | Yes |
| USA | $80-300+ | Yes |
The savings are staggering. A year's supply of tretinoin in Cambodia costs less than a single tube in the US — and you skip the dermatologist appointment and insurance paperwork.
Universal Tips (All Countries)
- Start with 0.025% if you've never used tretinoin. This is true regardless of where you buy it.
- Store in the fridge. All three countries are hot — tretinoin degrades in heat. This is not optional in tropical climates.
- Apply at night only. Tretinoin + sunlight = bad. Always use SPF 50+ the next day.
- Bring it home in original packaging. Customs in the US, UK, EU, and Australia generally allow personal-use quantities (6-12 tubes is fine).
- Check expiry dates before buying. High-turnover pharmacies have fresh stock; quiet ones may not.
- Budget for sunscreen too. The best tretinoin routine is wasted without daily SPF. La Roche-Posay Anthelios is widely available in all three countries.
Other OTC Skincare Worth Grabbing
While you're at the pharmacy, these are also prescription-free in SE Asia:
| Product | What It Does | Approx Price |
|---|---|---|
| Hydroquinone 2-4% | Melasma & hyperpigmentation | $3-8 |
| Azelaic acid 20% (Skinoren) | Rosacea, acne, pigmentation | $5-12 |
| Adapalene 0.1% (Differin) | Acne (retinoid alternative) | $3-6 |
| Clindamycin gel | Topical antibiotic for acne | $2-5 |
