Retin-A

Retin-A is a brand name for the medication tretinoin, a derivative of Vitamin A. It is primarily used in the treatment of acne, but has also been found to reduce the appearance of fine wrinkles and mottled skin discoloration, and to make rough facial skin feel smoother.

History

Retin-A was first developed by Albert Kligman in the 1960s as an acne treatment, and was later found to have significant anti-aging effects. It was approved by the Food and Drug Administration (FDA) in 1971.

Uses

Retin-A is used to treat acne and keratosis pilaris. It works by increasing the speed at which surface skin cells are replaced. This helps to unclog pores and decrease the formation of comedones, which are often the precursor to pimples.

In addition to its use in treating acne, Retin-A is often used as an anti-aging treatment. It has been shown to reduce the appearance of fine lines and wrinkles, improve skin texture, and lighten dark spots and freckles caused by sun exposure.

Side Effects

Common side effects of Retin-A include skin redness, dryness, itching, and scaling. These side effects are usually mild and improve over time as the skin adjusts to the medication. More serious side effects can include severe burning, redness, or irritation. If these occur, use of the medication should be discontinued and a healthcare provider should be consulted.

Precautions

Retin-A should not be used by individuals who are pregnant or planning to become pregnant, as it can cause birth defects. It should also not be used by individuals with eczema or sunburned skin, as it can cause severe irritation.
