Vitamin

Niacinamide

Also known as Vitamin B3

A gentle, versatile form of vitamin B3 that helps balance oil, calm the look of redness and support a healthy skin barrier.

What is niacinamide?

Niacinamide is a water-soluble form of vitamin B3. It's one of the easiest active ingredients to use because it works well alongside most other skincare and rarely irritates.

What it does for your skin

  • Helps regulate the look of oil and shine
  • Supports the skin's natural barrier and moisture levels
  • Calms the look of redness and blotchiness
  • Helps pores look smaller and skin tone look more even

How to use it

Niacinamide works morning and night. You'll find it in cleansers, serums and moisturizers. A moisturizer with niacinamide is an easy way to get it into your routine every day.

Who it's for

Almost everyone. It's especially helpful for oily, acne-prone and redness-prone skin, and it's a good companion to stronger actives like retinol and salicylic acid.

Common questions

Can I use niacinamide with vitamin C?
Yes. Modern formulas work well together.
Is niacinamide good for acne?
It helps balance oil and calm the look of redness, so it's a helpful part of an acne routine alongside salicylic acid or benzoyl peroxide.
Can I use niacinamide every day?
Yes, morning and night.
