What affect does vitamin A have on acne?
What will be an ideal response?
Adolescents need to know that massive doses of vitamin A have no beneficial effect on acne. The prescription medicine Accutane is made from vitamin A but is chemically different. Taken orally, Accutane is effective against the deep lesions of cystic acne. It is highly toxic, however, especially during growth, and has caused birth defects in infants when women have taken it during pregnancy. For this reason, women taking Accutane must agree to pregnancy testing and to using two forms of contraception from at least 1 month before taking the drug through at least 1 month after discontinuing its use. Should they become pregnant, they need to stop taking Accutane immediately and notify their physician.
Another vitamin A relative, Retin-A, fights acne, the wrinkles of aging, and other skin disorders. Applied topically, this ointment smooths and softens skin; it also lightens skin that has become darkly pigmented after inflammation. During treatment, the skin becomes red and tender and peels.
