The best niacinamide serum in 2019

Niacinamide (or the artist formerly known as vitamin B3) is a do-it-all ingredient that helps a variety of skin types. Rosacea-prone? Niacinamide can help soothe red patches. Breaking out? Niacinamide can help fight acne. Worried about fine lines? Niacinamide can help minimize the appearance of fine lines and wrinkles.

While no skin-care ingredient is right for everyone, I personally find niacinamide to be extremely effective and gentle enough for my fairly reactive skin. Before you dive in head-first, perform a patch test on a small, non-visible area, or see your dermatologist.

Niacinamide can be found in a ton of products like moisturizers and makeup primers. But the simplest, most direct way to incorporate it into your routine is a serum. They usually contain higher concentrations of active ingredients than other types of products, and can be rotated in and out of your routine depending on your skin’s current needs.

There are fantastic options to be found at every price point from department store to drugstore, but the one that’s right for your skin will depend on your budget, individual skin type, concerns, and preferences.
