What Niacinamide Is

The Basics

Niacinamide, also known as nicotinamide, is a water-soluble form of vitamin B3. It's naturally present in the body and found in foods like meat, fish, and grains.

How It Works

It supports the skin barrier, regulates oil production, reduces inflammation, and inhibits the transfer of melanin to skin cells.

Concentrations

Most skincare products contain 2% to 10% niacinamide. Higher concentrations don't necessarily work better and may irritate sensitive skin.

Why It's Popular

It's gentle, well tolerated, and compatible with most other ingredients.

How Niacinamide Supports Brighter Underarms

Reduces Pigmentation

Niacinamide inhibits the transfer of melanin to skin cells, helping to fade pigmentation over time.

Supports the Skin Barrier

A healthy barrier is better equipped to resist irritation, which is a common contributor to underarm pigmentation.

Reduces Inflammation

Niacinamide has anti-inflammatory properties that calm redness and irritation.

Regulates Oil Production

For those prone to folliculitis or odor, niacinamide can help regulate oil production.

Improves Skin Texture

It supports skin quality and smoothness.
