How to Feel Better Every Day
If your skin has dark patches, or melasma, which is notoriously difficult to fade, you may want to add vitamin C to your skin-care regimen. According to a 2012 study from Cairo University, topical vitamin C was shown to be more effective at lightening melasma than a glycolic acid peel—the previous gold standard for fighting splotchiness. You’ll get the best results with daily use, so try swapping your regular moisturizer or serum for one that contains vitamin C, says Elizabeth Hale, M.D., an associate professor of dermatology at New York University Langone Medical Center, in New York City. But choose your products carefully: Because vitamin C is photosensitive (meaning it starts to degenerate when exposed to light), it’s important to pick formulas that are kept in opaque bottles. Two to try: Avalon Organics Vitamin C Renewal Facial Cream ($22, avalonorganics.com) and Kiehl’s Powerful-Strength Line-Reducing Concentrate ($58, kiehls.com).
