Key Facts

What Is Niacinamide?

Niacinamide, also known as nicotinamide, is a water-soluble form of vitamin B3 (niacin). Unlike nicotinic acid, which can cause flushing and irritation, niacinamide is well-tolerated by most people and is widely used in skincare and nutritional supplements. It's an essential nutrient that your body needs for proper functioning and maintaining good health.

Health Benefits

Niacinamide supports energy production within cells by playing a crucial role in metabolic processes. It helps convert food into energy that your body can use effectively. Additionally, niacinamide supports healthy cholesterol and triglyceride levels, making it beneficial for cardiovascular health when taken as a supplement.

Skin Health Benefits

In skincare, niacinamide has become increasingly popular due to its multiple benefits. It strengthens the skin barrier, reducing transepidermal water loss and improving skin hydration. For those with oily or acne-prone skin, niacinamide reduces sebum production and minimizes pore appearance. It's also effective for reducing redness and irritation, improving skin texture and tone, minimizing fine lines and wrinkles, and providing anti-inflammatory effects.

Anti-Inflammatory Properties

Niacinamide's anti-inflammatory properties make it beneficial for various skin conditions including rosacea, eczema, and psoriasis. It helps calm irritated skin and reduces the appearance of redness. These properties extend beyond the skin, as niacinamide may help reduce inflammation throughout the body when taken as a supplement.

Safety and Usage

Niacinamide is considered safe for regular use in both supplements and skincare products. It's generally well-tolerated with minimal side effects and can be used by most skin types, including sensitive skin. In skincare, concentrations typically range from 4-5%, and it pairs well with other active ingredients like hyaluronic acid and retinol.
