Niacinamide's anti-inflammatory properties are responsible for its effectiveness in treating acne-prone skin. By reducing the inflammation of pimples, it helps alleviate mild to moderate forms of acne. Additionally, its smoothing properties help tighten skin pores, limiting the infiltration of bacteria and the proliferation of pimples.

Vitamin B3 also regulates sebum production, making it a valuable ally for oily and combination skin prone to blemishes. This triple anti-acne action positions niacinamide as a gentle and effective ingredient for treating problem skin.

Numerous studies have confirmed the anti-acne and sebum-regulating effects of niacinamide.

Although some hopes may be dashed, certain cosmetic ingredients, such as niacinamide, offer the potential to reduce the signs of skin aging. Thanks to its antioxidant action and ability to stimulate the production of skin collagen, this vitamin has remarkable anti-aging effects. Indeed, sagging skin is largely caused by the oxidation of epidermal cells due to free radicals. By slowing oxidative stress, vitamin B3 helps preserve the skin's youthfulness.

Niacinamide can play a crucial role in mitigating the effects of environmental damage by improving the skin barrier. This helps reduce the skin's susceptibility to pollution, UV rays, and chemicals and household products, which can accelerate the skin's aging process.

From the age of 40, when sun exposure begins to gradually diminish, brown spots, often called "sun spots" or "age spots," begin to appear on the skin. These spots are caused by excess melanin accumulating in the epidermis and are often perceived as unsightly and unpleasant.

Niacinamide has the ability to regulate melanin production, thus limiting the appearance of dark spots. A 2005 study confirmed niacinamide's anti-aging and anti-pigment spot effects.

Vitamin B3, moisturizing, soothing, and anti-inflammatory, is particularly effective in treating intense dryness and strengthening the skin barrier, which helps prevent eczema. By stimulating the synthesis of keratin and ceramides, it improves skin permeability and helps soothe atopic skin.

Niacinamide has the advantage of being very well tolerated by all skin types, including the most sensitive, a rare characteristic among anti-aging and anti-acne active ingredients. It is stable and non-photosensitizing, which allows it to be used both morning and evening.

To be effective, products containing niacinamide should ideally contain between 2 and 5%. It is recommended to apply the treatment regularly for several weeks, even if you don't see immediate visible results.

It's important to note that niacinamide is less active than some other ingredients with similar effects, which contributes to its very good tolerance. To see the effects on the skin, it is necessary to be patient and persevere, as it can take a little longer to work.

Furthermore, it is important to know that niacinamide is not very compatible with vitamin C, as their respective actions tend to cancel each other out. Therefore, it is advisable not to use products containing vitamin C at the same time as niacinamide products.
