Vitamin A is also available in topical forms, known as a retinoids, that are used as medications to treat skin conditions. Retinoids were initially marketed and approved to combat very severe acne. But researchers soon discovered another valuable property of retinoids: They could reduce the signs of photoaging (aging of the skin from sun exposure) and were soon used as a wrinkle treatment.
Isotretinoin (formerly marketed under the brand name Accutane) is an oral medication that may be prescribed for people who cannot control severe acne through topical treatments or with antibiotic medications. Though it's been found to be extremely effective in managing acne, it has serious side effects, including birth defects if taken by pregnant women. Generic isotretinoin may cause depression and, rarely, thoughts of suicide. And while new information is emerging that it could contribute to or worsen irritable bowel disease, a study found that isotretinoin use did not affect the incidence of IBD.
Tretinoin (Retin-A, Avita, Renova) is a topical vitamin A prescription acne treatment. It's also used to help reverse damage to the skin from sun exposure. Tretinoin works as an irritant, which results in more rapid turnover of skin cells, causing old cells to die more quickly. Tretinoin helps acne disappear as it sheds old skin cells. While it also minimizes the appearance of wrinkles and dark spots on the skin, exactly how it works against wrinkles and sun damage isn't completely understood.
The uses of vitamin A have evolved over the years, from the body's natural needs to man-made treatments that get rid of pimples and minimize wrinkles and dark spots on the skin. Whether you seek acne or wrinkle treatment, buy it over-the-counter or with a doctor's prescription, be aware of possible side effects, and make sure to follow all instructions carefully.
