3 Reasons Why You Need Vitamin C in Your Skin-Care Routine – Cosmopolitan.com

1. It fades and prevents spots.

“Vitamin C blocks the effects of tyrosinase (an enzyme responsible for pigment production in skin cells) while simultaneously reducing oxidation of already present pigment, preventing it from getting darker,” explains dermatologist Shereene Idriss, MD. “Products with 10 to 20 percent of the ingredient are more likely to be effective on spots,” says NYC derm Julie Karen, MD. Anything under 10 percent functions as a powerful antioxidant.

2. It smooths lines.

Applied topically, vitamin C can stimulate collagen production to reduce wrinkles and increase skin’s firmness, says Ellen Marmur, MD, a derm in NYC. Same goes for diet: “Eating vitamin C-rich foods, like oranges and brussels sprouts, is essential for collagen production,” explains Dr. Marmur.

3. It boosts sunscreen.

SPF is critical for protecting skin — but it’s not perfect. That’s where vitamin C comes in. Layered under your sunscreen (or as a part of the formula), “it helps neutralize free-radical damage from UV exposure,” explains Dr. Karen.

Good to Know

  • Look for ascorbic acid on the label. This specific form of the vitamin penetrates skin best.
  • Buy it in opaque, airtight packaging. “When exposed to light and air, vitamin C will oxidize and can become inactive,” says Dr. Idriss.
  • Wait 10 minutes before or after applying products with AHAs or BHAs. “They may neutralize the effects of some forms of vitamin C,” says Dr. Marmur.
