Is It Safe to Combine Skincare with Niacinamide and Vitamin C?

Niacinamide, it turns out, is also a vitamin. According to Glamour UK, niacinamide is the topical version of vitamin B3. The derivative soothes a wealth of skin issues, from excess oil and acne to fine lines and a weak skin barrier. The anti-inflammatory ingredient prevents moisture loss and gets rid of irritation.

There are various types of vitamin C, says 100% Pure, with ascorbic acid being the most prominent one in skincare use. The antioxidant fights toxins, such as pollution, that touches your skin and can help to prevent sun damage. As a brightening ingredient, it's often used to reduce the appearance of hyperpigmentation, wrinkles and fine lines, and acne (via Harvard Medical School.)

Due to the fact that both ingredients share so many benefits, they can be used together, complementing one another and possibly strengthening the effects. However, if you have sensitive skin, you may want to ask a dermatologist before layering the two, according to MindBodyGreen. If you're using them in the same routine, Vogue India suggests applying the vitamin C before the niacinamide, followed by a moisturizer and sunscreen during the day.
