Niacinamide, also known as vitamin B3, is a multi-functional skincare ingredient prized for its ability to brighten, strengthen, and balance the skin. It is a water-soluble vitamin that works with the skin’s natural processes to improve hydration, reduce inflammation, minimize pores, and regulate oil production, making it suitable for all skin types—including sensitive, acne-prone, and aging skin.
Key Benefits of Niacinamide:
- Brightens Skin and Reduces Hyperpigmentation
Niacinamide inhibits melanin transfer, helping to fade dark spots, sun damage, and post-inflammatory hyperpigmentation (PIH). This makes it a popular ingredient in brightening treatments and products aimed at evening out skin tone. - Strengthens the Skin Barrier
By boosting the production of ceramides and lipids, niacinamide reinforces the skin barrier, reducing moisture loss (transepidermal water loss or TEWL) and improving overall skin resilience. This is particularly beneficial for those with dry, sensitive, or compromised skin conditions like eczema and rosacea. - Reduces Redness and Inflammation
Thanks to its anti-inflammatory properties, niacinamide helps calm irritated skin, making it effective for redness, acne, and sensitive skin conditions. It also soothes rosacea-prone skin by reducing flushing and inflammation. - Regulates Oil Production and Minimizes Pores
Niacinamide helps control sebum (oil) production, which can reduce clogged pores, blackheads, and breakouts. Over time, it also improves skin texture and reduces the appearance of enlarged pores, making it an excellent ingredient for oily and acne-prone skin. - Boosts Collagen and Fights Fine Lines
Studies have shown that niacinamide stimulates collagen synthesis, improving skin elasticity and reducing fine lines and wrinkles. This makes it a great addition to anti-aging formulations that focus on maintaining firm, youthful skin.
How to Use Niacinamide in Skincare
Niacinamide is commonly found in serums, moisturizers, toners, and even sunscreens, often at concentrations of 2% to 10%. It pairs well with hydrating ingredients like hyaluronic acid, barrier-strengthening ceramides, and brightening agents like vitamin C.
Because it is gentle and non-irritating, niacinamide can be used daily, both morning and night, and is suitable for all skin types. It is an excellent multi-tasking ingredient that addresses multiple skin concerns at once, making it a staple in modern skincare routines.
Nicotinamide (INN, BAN UK) or niacinamide (USAN US) is a form of vitamin B3 found in food and used as a dietary supplement and medication. As a supplement, it is used orally (swallowed by mouth) to prevent and treat pellagra (niacin deficiency). While nicotinic acid (niacin) may be used for this purpose, nicotinamide has the benefit of not causing skin flushing. As a cream, it is used to treat acne, and has been observed in clinical studies to improve the appearance of aging skin by reducing hyperpigmentation and redness. It is a water-soluble vitamin.

Side effects are minimal. At high doses, liver problems may occur. Normal amounts are safe for use during pregnancy. Nicotinamide is in the vitamin B family of medications, specifically the vitamin B3 complex. It is an amide of nicotinic acid. Foods that contain nicotinamide include yeast, meat, milk, and green vegetables.
Nicotinamide was discovered between 1935 and 1937. It is on the World Health Organization's List of Essential Medicines. Nicotinamide is available as a generic medication and over the counter. Commercially, nicotinamide is made from either nicotinic acid (niacin) or nicotinonitrile. In some countries, grains have nicotinamide added to them.
