Niacin goes by many names—niacinamide, nicotinic acid and myristyl nicotinate, just to name a few—but these are all just fancy terms for different forms of vitamin B3, an essential nutrient which just so happens to do wonders for your skin.

1. Niacin helps smooth wrinkles.

Niacin benefits your skin by stimulating production of collagen and elastin, which helps to smooth those pesky fine lines and wrinkles. One of our favorite niacin anti-agers is SkinCeuticals Metacell Renewal B3, which combines 5% niacinamide with a tri-peptide concentrate and advanced moisturizers to smooth wrinkles and increase skin elasticity for a more toned facial contour.

2. It’s also great for acne-prone skin.

If you’re constantly dealing with acne blemishes, adding a niacin product to your routine is one of the best ways to get clear skin. Niacinamide heals acne by targeting the first step in the acne cycle, reducing the inflammation that would otherwise lead to sebum oxidation, clogged pores, bacteria growth and eventually an angry pimple. We recommend EltaMD UV Clear Broad-Spectrum SPF 46 Sunscreen – Untinted because it soothes, heals and protects acne-prone skin with niacinamide in a fragrance, paraben and oil-free formula.

3. Niacin promotes an even skin tone.

If you’ve spent a lot of time in the sun, you know that it can lead to dark spots and other forms of hyperpigmentation. Niacin helps brighten these dark spots over time because it stops melanin from rising through the cells of the dermis to the epidermis. Epionce Intense Defense Serum is one of our picks because it combines a complete vitamin complex (A, B, C, D, and E) with potent botanicals to strengthen skin and minimize signs of aging. Your complexion is left soft, smooth and even-toned.

4. Niacin keeps your skin moisturized.

By now you know that vitamin B3 helps to strengthen your skin barrier, and that leads to our next niacin benefit: with consistent use, this ingredient helps your skin stay hydrated. Skin with a healthy barrier keeps moisture from being lost through evaporation, and this means less dry, flaky and irritated skin. For the delicate eye area, we love Replenix Enriched Eye Repair Cream. This silky hydrating cream features niacinamide, vitamin C, hyaluronic acid, retinol, peptides, caffeine (we could go on and on)—all these ingredients work synergistically to smooth lines, strengthen skin, reduce dark circles and depuff for younger-looking eyes.

5. It soothes rosacea symptoms.

Rosacea is cyclical and incurable, but using niacin in your skin care routine can help reduce the redness, bumps and irritation that are common with this condition. NIA24 Intensive Recovery Complex works with 5% Pro-Niacin, peptides, hyaluronic acid and antioxidants to soothe and strengthen skin while alleviating rosacea symptoms. This advanced hydrating cream is also a great all-around anti-aging product, and is ideal for all skin types, including sensitive skin.
