On the market, there are thousands of skin care ingredients used for whitening, but they have been proven to be effective and widely accepted by the public, and niacinamide is counted as one! Since niacinamide was "popular" by Procter & Gamble, it quickly blew a fierce wind in the skin care industry, and the niacinamide suddenly became a popular "whitening spot artifact" for the whole people.
<h1 class="pgc-h-arrow-right" > what is niacinamide? </h1>
Niacinamide is a derivative of vitamin B3, also known as vitamin B3, is a member of the vitamin family, and is also recognized by the field of cosmetic skin science to date as a skin anti-aging factor. Its small molecular weight allows it to quickly pass through the surface layer of the skin and penetrate deep into the skin, blocking melanin transmission and accelerating metabolism.
<h1 class="pgc-h-arrow-right" > the whitening and spotting principle of niacinamide</h1>
Melanin determines the black and white color of the skin tone, and also makes people grow spots. However, after melanin is generated, only the skin that is transported to the stratum corneum will become black, and if melanin accumulates in large quantities in the epidermis, it will also grow good spots. Niacinamide can block the transport of melanin and accelerate the shedding of pigment cell keratin, thereby avoiding skin darkening or long pigment spots.
Two major roles of niacinamide:
1. Prevention: prevent blackening and prevent long pigmentation
2. Dilution: fade the pigmentation spots that have grown out, brighten and whiten the skin
Although niacinamide can indeed bring about visible skin changes, less pigmentation and acne marks, it also has drawbacks: that is, it is irritating! In order to achieve the effect of whitening, the concentration of niacinamide must be above 2%, and the greater the concentration, the better the relative effect, but the greater the stimulation.
Therefore, for the first time to use niacinamide skin care products, it is recommended to choose a low concentration and do a good tolerance test behind the ear. Niacinamide can be tolerated slowly, so your concentration can increase as your skin can withstand it.
