What Are Those Ingredients in Your Skin-Care Products?
Dermatologists give a crash course on what goes into skin-care products.
Alpha Lipoic Acid
Also known as: Lipoic acid.
Good for: All skin types, except very sensitive skin.
What it treats: Sun damage, aging.
How it works: Alpha lipoic acid "helps with exfoliation and the stimulation of collagen, which may lead to a smoother appearance of the
skin," says Ronald R. Brancaccio, a clinical professor of dermatology at the New York University School of Medicine, in New
York City. Since it's a powerful exfoliator, avoid it if your skin is sensitive or prone to redness.
