General information
Tretinoin is a retinoid. Retinoids are drugs that are derived from vitamin A. On the skin it acts to cause a reduction of natural skin oil, thereby assisting in the treatment of acne.

In South Africa tretinoin is registered for the treatment of acne.

In some patients acne may worsen during the first few weeks of treatment with this medication. This, together with symptoms such as very dry, flaky and itchy skin, usually improves as treatment continues.

Tretinoin may also leave your skin more susceptible to sunlight and sunburn. It is advised to keep sun exposure to the minimum and wear sunscreen and protective clothing whenever exposed to the sun while using this medication. If sunburn occurs, discontinue use until the skin is fully recovered.

Avoid contact with the mucous membranes, eyes, mouth, angles of the nose and areas with eczema, as tretinoin’s excessive drying effects here may cause irritation.

Severe caution is advised to prevent falling pregnant while taking this medication as this group of drugs can cause abnormalities in the foetus. Tretinoin should not be used in women of childbearing age, unless they are using effective contraception as a precaution.

For this medication to be effective, it has to be applied regularly, even if you do not notice an immediate effect. Excessive application will not produce better or more rapid results. Optimal results may only be acquired after a few weeks of use.

Tell your doctor about all other medicines you are taking, including prescription and non-prescription medicines, vitamins and herbal supplements.

How does tretinoin work?
Tretinoin reduces the production of sebum, the oily substance produced by sebaceous glands in the skin. This causes drying and peeling of the skin, making it useful in treating acne. It is also believed to have mild anti-inflammatory and antibacterial properties. It may furthermore unblock blackheads and reduce the formation of them.
