Is tretinoin prescription-only in Malaysia?
Not in the way many guides say. The Poisons List, which is the First Schedule to the Poisons Act 1952 as updated by P.U.(A) 125/2024, puts tretinoin in Group C, not Group B. Group B is the prescription group. The list and the Act were read on the Ministry of Health pharmacy website before this was written, because online guides contradict one another.
Group C is still a controlled category. Section 22 of the Act says a Group C poison may not be sold by retail except as a dispensed medicine, or where the sale would have been allowed for a Group B poison. The Act defines a dispensed medicine as one supplied by a doctor to his or her own patient, or supplied for the treatment of a particular individual by a licensed pharmacist on licensed premises. So tretinoin is handed to a named person by a doctor or a pharmacist. It is not something you take from a shelf.
What does the Poisons List say about each product?
Here is each one as the source states it.
Tretinoin: Group C, all preparations.
Adapalene: Group B, all preparations. Under section 21 it is supplied by a doctor, or by a pharmacist on a prescription.
Isotretinoin: Group B, all preparations. This is the acne medicine covered in the piece on oral isotretinoin.
Retinol and its esters: three lines. Group B applies to pharmaceutical dosage forms for human use containing more than 10,000 international units of vitamin A per dosage unit. Group C applies to preparations for parenteral administration, which means by injection, unless they fall in Group B. Every other preparation is listed as exempt. A skincare product containing retinol is not in Group B or C, so the Poisons List does not control it. It is regulated as a cosmetic instead.
What is the difference between Group B and Group C?
Group B needs a prescription. Section 21 lets a pharmacist supply a Group B poison only as a dispensed medicine on a prescription from a registered medical practitioner, dentist or veterinary officer, written, signed and dated, naming the patient and stating the amount and dose. A doctor may also supply it directly to his or her own patient. The Act text for Group C does not carry that prescription wording, and it still limits supply to dispensed medicine.
That is a plain reading of the text, and it has limits. The list and the Act set who may supply and how. They do not tell you how any single registered product is conditioned, and they cannot settle from the list alone what happens at a given counter. The ministry's copy of the Act is the 1989 revision with amendments to 2009. If a product's status matters to you, ask the pharmacist.
Can a cosmetic contain tretinoin or retinol?
A cosmetic cannot contain tretinoin. Retinol is treated differently. NPRA's cosmetic guidelines follow the ASEAN Cosmetic Directive annexes. In the Annex II release of 10 June 2026, the list of substances that must not form part of a cosmetic, tretinoin (retinoic acid and its salts) is entry 375. A skincare product that lists tretinoin or retinoic acid has stepped outside the guidelines.
No entry for retinol was found in Annex II, or in Annex III, the list of substances allowed only within limits. So no Malaysian strength cap for retinol in cosmetics can be pointed to here, and none is quoted from memory. Cosmetics are notified to NPRA through its Quest3+ system. They are not registered as medicines.
How do I check a product before I use it?
Read the ingredient list for retinol, retinyl compounds, tretinoin or retinoic acid, and check the label for a notification or registration number. The steps for looking a product up on the NPRA system are in how to check a cream in Malaysia. Do not treat a marketing word such as clinical or medical-grade as a legal category. The categories above are the legal ones.
Is tretinoin stronger than retinol, and which works better?
Tretinoin is the medicine and the better studied of the two. A 2025 network meta-analysis pooled 23 randomised trials with 3,905 people. It found that both tretinoin and retinol improved fine wrinkles and did better than the other options for hyperpigmentation, and that tretinoin had the most favourable safety profile of the agents compared. The authors name limited racial diversity and possible commercial bias as limits.
A 2024 systematic review calls tretinoin the gold standard for photoaging and says its poor tolerability often limits its use. Among the 25 studies, the agents compared with it were better in 7, equivalent in 13 and worse in 3, and most were less irritating. The same review says most of these comparison studies are of poor quality or biased, so no alternative has been shown to be a better first choice. Retinol is a vitamin A relative that many people tolerate better, though the reviews do not settle which suits whom. Neither review says which one suits your skin. That is a diagnosis question, as in adult acne or pigmentation that keeps returning.
Can I use these in pregnancy?
Not without your doctor's advice. NPRA's 2019 safety alert says oral retinoids are highly teratogenic, meaning they can cause birth defects, and that topical retinoids, despite negligible absorption into the body, are as a precaution contraindicated in pregnant women and in women planning a pregnancy. It names adapalene and tretinoin among the registered retinoids.
The alert is about retinoid medicines. It does not address retinol in skincare, so a doctor is the person to ask. Whatever goes on your skin, sun protection belongs under it, and what SPF leaves out covers the tropical detail.
So what can I actually buy?
Retinol skincare, as a cosmetic, from any shop that sells notified products. Tretinoin, only by supply from a doctor or a pharmacist to you as a dispensed medicine. Adapalene, on a prescription. Which one, at what strength, and whether a retinoid suits the problem at all are the decisions a doctor makes, and they include the pregnancy question.
A cream can be lawful and still wrong for the skin in front of it, and a strong claim on a jar is not a legal status.
