Tretinoin is a vitamin A derivative used to reduce symptoms of acne, wrinkles and other minor skin blemishes, and, in higher doses, to treat certain types of skin cancer.

While the medication is available in a tablet and oral solution, the vast majority of patients buy tretinoin as a topical cream or gel which is applied directly to the skin. Because it is a relatively potent medication which may cause harmful side effects, many areas require a prescription to buy tretinoin in any form.

The medication is sold under quite a few brand names, including Retin-A, Tretin-X, Rejuva-A, Avita and many others. It is also available as a generic.

Genuine Skin Rejuvenation

Tretinoin has been prescribed for skin rejuvenation since the early 1970s, and continues to be widely used today, while countless other skin treatments have come and gone. This is a testament to the medication's effectiveness--it really does work, and evidence of it working on a molecular level has been demonstrated in numerous studies.

Most skin treatments advertise how the product moisturizes, supplies the skin with essential vitamins or minerals, and other such skin supplementation. Tretinoin takes a different approach; it irritates skin cells, causing them to grow and die quicker than usual. Dead cells are then replaced with new, healthy skin cells. This process continues as long as treatment does; rapid replacement of skin cells prevents new blemishes from forming.

The medication also promotes retention, health and formation of collagen, which keeps skin firm and supple. Collagen breaks down with age and sun exposure, resulting in dry, saggy skin. In studies, patients using tretinoin have shown to have significantly more new collagen formed than those not using the product, and the new collagen is retained for years even if treatment stops.

People buy tretinoin to treat a range of blemishes, including:

• Acne or pimples
• Keratosis pilaris
• Wrinkles or fine lines
• Freckles
• Darkened skin
• Rough skin
• Stretch marks

Treatment typically lasts several months at minimum, depending on the condition being treated and its severity. Effects may be noticeable after 3 or 4 weeks of use, but it sometimes takes upwards of 6 months of treatment to be significant. Some conditions, particularly acne, may briefly worsen when treatment starts; this should pass within a few days.

Tretinoin's effectiveness also depends on the cause of the condition; it may produce only minor improvements in deep wrinkles from aging or some genetic conditions.

Before you Buy Tretinoin

As this medication's primary effect is to irritate and destroy skin cells, use requires some caution. As long as the product is being used and for several months after treatment stops, be aware that:

• Skin may be considerably more sensitive to sunlight or other sources of UV rays, increasing the risk of severe sunburn and development of certain types of cancer if exposed.
• Skin may be thinner than before, and more sensitive to abrasive materials, astringents, or other mild irritants that aren't normally noticed.
• Mild burning, stinging, redness and inflammation may occur when the product is applied, and this may continue throughout treatment.

The most important thing to keep in mind while using tretinoin is that more is not necessarily better. Patients usually start with a very low dose in very small amounts--about the size of a pea to cover the whole face--and the product may be applied only once every few days. Dosage and frequency may gradually be increased over time if needed, but it should always be done with caution.
