Niacinamide is a form of vitamin B3 that can be taken as a supplement or applied topically to the skin. It is found in many foods including meat, fish, milk, eggs, green vegetables, and cereals. Niacinamide has several benefits for the skin, including:
Positive effects:
- Helps build keratin, a protein that maintains skin health.
- Helps retain moisture by growing a ceramide (lipid) barrier, which is beneficial for all skin types, especially if you have eczema or mature skin.
- Reduces inflammation, which may help ease redness from eczema, acne, and other inflammatory skin conditions.
- Minimizes pore appearance by keeping skin smooth and reducing oil production.
- May help treat hyperpigmentation and damage related to sun exposure.
- Makes skin stronger, smoother, and brighter.
Negative effects:
- Niacinamide cream might cause mild burning, itching, or redness when applied to the skin.
Niacinamide concentration can vary across products, though most formulations are 5 percent or less. Some reports suggest that 5 percent formulas are effective in treating hyperpigmentation and damage related to sun exposure. If you have sensitive skin, you may want to start with a lower concentration. Formulas with 2 percent niacinamide may help ease symptoms of eczema and similar conditions. Niacinamide may be listed as “niacin” and “nicotinamide” on product labels.
Niacinamide may be used alongside other active ingredients for optimal results. For example, some reports suggest that it is helpful to pair niacinamide with other skin care products to maximize its benefits, such as anti-aging formulas. It is important to read each product label carefully and follow all instructions for use.
