Do You Actually Need Vitamin C Serum? A Dermatologist Explains

Dermatologist Dr. Dray breaks down the science behind topical vitamin C, including what vitamin C does for the skin, how it may help with wrinkles, collagen production, photoaging, dark spots, and hyperpigmentation, and whether a vitamin C serum is actually necessary for an effective skincare routine. Vitamin C, also known as ascorbic acid, is a powerful antioxidant that can help neutralize free radicals generated by UV radiation, pollution, and other environmental exposures. It also plays an important role in collagen synthesis and may help reduce melanin production, making it an interesting ingredient for both anti-aging skincare and hyperpigmentation. But how strong is the clinical evidence? And is vitamin C actually better than ingredients like tretinoin, retinoids, niacinamide, hydroquinone, or sunscreen? Dr. Dray discusses the research, the limitations of vitamin C studies, the importance of formulation and stability, potential skin irritation, and whether expensive vitamin C serums are worth the money.
