Tretinoin, also known as Retin-A (the pharmaceutical form), or all-trans retinoic acid (ATRA), is a form of well-known vitamin A, particularly the carboxylic acid. It belongs to group of retinoids, and is one of the most important basic medicines, included in the List of Essential Medicines by WHO. Tretinoin is essential in curing acne, and is commonly used by people to get rid of the blackheads on their face. There are other possible uses of this drug, see below.
Retin-A can come in several medical forms: as a gel or a cream or ointment for topical application, and as tablets or pills for oral use. Usually, people buy Retin-A online with no rx in form, depending on their needs: for acne treatment, the ointment is most convenient. This medication is not very affordable: if you want to buy cheap Retin-A, you will have to look for it in an online pharmacy.
Most common medical use of Tretinoin is the prevention and treatment of acne vulgaris: this is a skin disease resulting in blackheads, appearing on face of the patient. Applying Retin-A in form of gel or ointment on the skin makes such blackheads disappear within some period of time, refreshing the skin due to its mechanism of action that will be disclosed later in this article. Because of it, some people also use the drug to fight the stretch marks on skin.
Mechanism of action of Tretinoin is based on induction of division of epithelial cells, which makes the skin refresh and renew more often and effectively. The medication also has an effect that prevents the epithelial cells from sticking together, thus preventing the formation of blackheads, the main acne symptom. It has a natural effect similar to the effect of vitamin A on body, but it works better. This is why it is hard to find low cost Retin-A in local drug stores.
If you are eager to make the most of your treatment, you should be careful using it. It is recommended to consult your doctor before you start using Retin-A; there are several important precautions you have to fulfill. Tretinoin (Retin-A) should not be used by pregnant women, or those women who plan to become pregnant; some forms of the medication have pregnancy category D and may harm the fetus. You should not use any other cream or ointment along with Retin-A, in case it contains alcohol, spices, sulfur, lime or aspirin, or has a drying effect: such creams may cause side effects in patients using the drug.
Possible side effects of Tretinoin can manifest in the following forms: irritation, swelling, redness or blistering. The ointment makes the skin more sensitive to ultraviolet and thus increases the risk of sunburn.
