Here’s what to look for in a double-duty product: The anti-acne ingredient: Look for salicylic acid, a mild peeling agent that helps clear away dead skin cells so they don’t clog your pores. Other common acne fighters like tea tree oil, sulfur, and benzoyl peroxide target flare-ups caused by bacteria, meaning they’re not always effective for later-in-life breakouts, which tend to be hormonally driven, says Diane Walder, MD, a cosmetic dermatologist based in Miami. And stick with non-oil moisturizers like glycerin and hyaluronic acid that hydrate skin without clogging pores. The anti-aging ingredient: Look for retinoids, a vitamin A derivative listed as “retinol” in over-the-counter products. “Retinoids stimulate collagen growth to make skin appear firmer and less wrinkled,” Walder says. Another good anti-wrinkle option to hunt for? Peptides, which also tell your skin cells to pump up the collagen production. Find both in the Neutrogena All-in-1 Acne Control Facial Treatment ($11, neutrogena.com), which blends salicylic acid and retinol, and Hydropeptide Redefining Serum ($130, hydropeptide.com), which contains a cocktail of salicylic acid, hyaluronic acid, and five different types of peptides.
