So what are the specific properties that make witch hazel so popular as an anti-inflammatory acne-fighter? “It has tannins naturally, which make it an astringent and contains anti-inflammatory properties that may help acne,” says board-certified dermatologist Morgan Rabach, M.D., and co-founder of LM Medical NYC. Tannins have been shown in research to be beneficial for the skin barrier1, too, so it’s not just anecdotal evidence to support these claims. So how can you tell if it’s a good ingredient for you? First, spot test on your arm. This is a good rule for any skin care product, but it tends to be even more important for stronger actives (like acids, enzymes, and astringents). Then, slowly introduce the product to your skin care routine. Start with a few times a week and build as tolerated. Always stop if your skin gets red or too dry—and “if you notice any stinging or burning, discontinue immediately,” says Nazarian.
