Today's whitening products, without niacinamide, have almost been swept into the ranks of low-end products.
Whitening, anti-aging, oil control, pore shrinkage, acne removal, the effect of niacinamide covers almost all skin shortcomings, well-deserved problem skin savior.
Niacinamide (VB3)
The first to apply niacinamide to skin care products is definitely a genius, as a member of the vitamin family, compared to the long-famous vitamin c and e, vitamin B3 (also known as vb3) has a bumpier road to fame.
VB3 is widely present in animals and plants, but it really began to be used in cosmetics in 1974, when the British girish parsad mathur first used 1-5% niacinamide in sunscreen cream to achieve an unexpected whitening effect.
Since then, as if opening the door to a new world, the world's major skin research institutions have invested in the study of niacinamide, after several years of research and certification, niacinamide for the whitening effect is reliable.
But the success of the research and the launch of the market, the middle of the time to consume a long time, niacinamide really began to be used in large quantities in skin care products, and put on the market, starting from P&G olay oil launched products containing niacinamide. The success of Olay, other brands under Procter & Gamble have also begun to launch niacinamide products, and other companies have followed suit, which has led to such a huge market share of niacinamide.
Although the effect is powerful, the accompanying irritation is often criticized, and when using high concentrations of niacinamide products, there will be different degrees of intolerance.
Redness, swelling, itching, and tingling often make you lose confidence in niacinamide.
Since the ingredients have such a good effect, it would be a pity if they were discarded because of the disadvantage of irritation.
We began to study the concentration critical point that will cause irritation, niacinamide, the irritating component is mainly niacin, when the pH value is 6, niacinamide is very stable, when the ph is higher or lower than 6, niacinamide will be hydrolyzed to form niacin.
The pH of human skin is about 4.5 to 6.5, which is a weakly acidic environment, only in this environment, the skin can be in the best state of nutrient absorption, and at this time, the skin's ability to resist external invasions and elasticity, radiance, moisture, etc., are the best state.
And most skin care products have their own pH, acidic or alkaline, when using niacinamide products, do not mix with other products, if mixed, will lead to skin pH change, release a lot of niacin, cause irritation to the skin.
Now the more famous niacinamide products:

According to the feedback of use, the whitening effect of niacinamide is still good, the disadvantage is that it is irritating, and some skin is intolerant, especially sensitive skin, which is more susceptible to irritation.
Whitening is a long-term process, can not expect to be fast, 28 days a skin's own metabolic law or to follow, can not because of the use of 2, 3 days no effect on the effect of nicotinamide.
If a product is used once or twice, there is a very obvious whitening effect, often adding heavy metals, hormones and other ingredients, the effect can refer to the Wei and Jin Dynasty fifty scatters, doped with a large amount of lead mercury, after taking the skin quickly whitening, delicate, but after a while it will quickly decay, can only apply heavy powder to cover up the aging of the skin.
If you want to whiten, you still have to honestly see the ingredients and take care of it safely.
