Discover how niacinamide works on the skin, improving texture and tone and fighting ageing.
What is niacinamide?
Niacinamide, or vitamin B3, is an amine derived from vitamin B3 (nicotinamide). It is widely used in the cosmetics industry for its beneficial properties on the skin. Its molecular structure gives it powerful antioxidant, anti-inflammatory and moisturising properties, which make it a valuable ingredient in many face and body care products.
How it is used and how it works on the skin
Niacinamide is usually incorporated into creams, serums, masks and other skincare products. Applied topically, this substance penetrates the surface layers of the skin, where it works on several levels.
It increases the synthesis of ceramides, lipids that are essential for the skin's barrier function, thereby improving its hydration and protection.
It also stimulates the production of collagen and elastin, helping to reduce wrinkles and improve skin elasticity.
What it pairs with: from salicylic acid to retinol to vitamin C.
Niacinamide combines well with a variety of other ingredients to enhance its effects.
Pairing it with salicylic acid, for example, can be effective in treating acne, since salicylic acid exfoliates the skin and penetrates the pores, while niacinamide reduces inflammation and normalises sebum production.
Retinol, a derivative of vitamin A, can be combined with niacinamide to improve skin texture and reduce the signs of ageing, while vitamin C, for example, could enhance its antioxidant effect.
It also works well with hyaluronic acid to improve the hydration of the epidermis, and with zinc to reduce excess sebum.
Combining it with glycolic acid in high concentrations should however be avoided, to prevent skin irritation.
What niacinamide is for
Niacinamide offers a wide range of benefits for the skin:
- It regulates sebum production, making it ideal for acne-prone skin.
- It protects against damage caused by free radicals thanks to its antioxidant properties, which slow down the skin ageing process.
- It is effective in treating hyperpigmentation and dark spots, evening out the tone of the skin tissue.
- It has moisturising capabilities that make it suitable for dry skin too.
- It improves hair health: thanks to its moisturising and strengthening properties, it promotes growth, makes hair stronger and shinier, and also regulates sebum on the scalp.
- It reduces the appearance of fine lines and irregularities on the skin's surface.
What kinds of products on the market contain niacinamide
A wide range of products containing niacinamide are available on the market, formulated to meet a variety of skin needs.

Frequently asked questions
What are the contraindications of niacinamide?
Niacinamide is generally considered safe for most people, but individuals with extremely sensitive skin, a known allergy or sensitivity to other products containing B vitamins may experience irritation or skin reactions. It is advisable to perform a patch test on a small area of skin before large-scale use and to consult a dermatologist if in doubt. In any case, it is always best to consult a professional before use if you are already using specific treatments on the epidermis that may have unknown interactions with this ingredient.
What should not be mixed with niacinamide?
- In general it is best to avoid combining niacinamide with products containing ascorbic acid (vitamin C) in high concentrations, as this could reduce its effectiveness. Alpha hydroxy acids (AHA) and beta hydroxy acids (BHA) can also reduce the effectiveness of niacinamide if used at the same time in high concentrations.
How many times a week can niacinamide-based products and/or treatments be used?
- The frequency of use of niacinamide obviously depends on the individual needs of the skin, the dosage and the concentration of the product. In general, it is advisable to start with moderate use, for example two or three times a week, and then adjust the frequency according to the skin's tolerance and the desired results. It is always a good idea to consult the product instructions and, if necessary, seek advice from a dermatologist or another professional in the field.
