Nicotinamide Nicotinamide, also known as vitamin B3, has good stability, small molecular weight and strong permeability. Different concentrations of nicotinamide can play different roles, such as moisturizing, oil control, acne removal and whitening. The whitening effect is mainly reflected in the third link: inhibiting the transmission and transportation of melanin. It should be reminded here that nicotinamide also needs to slowly establish tolerance!
1, Olay white bottle 40mlProX essence Olay white bottle is a double explosion of 1 1 every year, and many girls have included it in the list of Double Eleven. In addition to nicotinamide, amide is added in a breakthrough way, which can intercept the signal of melanin production and inhibit melanin production.
If the light-sensitive white bottle of Olay focuses on removing yellow and brightening, then this ProX is mainly for whitening and brightening spots. Personally, I prefer this one. The small white bottle is a very clear egg white texture, which is absorbed quickly and has a good skin feeling. I feel that all skin types can be easily controlled, and there is no photosensitive component, so I can use it safely during the day.
2. Avon Avon's new living nicotinamide clear essence 50ml small crystal bottle Avon's nicotinamide small crystal bottle is smaller than the small white bottle of Olay. The main components are nicotinamide and arbutin with a concentration of 6%, and patented anti-sugar components. The formula is good, and there are two ways to whiten, which are both reducing and inhibiting. However, the new version of the formula removes VC, which is a bit regrettable.
In addition, I want to remind you that the alcohol content in the small crystal bottle is a little high. I'm a mixed oil skin. I don't care much about alcohol, but I should pay attention to sensitive muscles.
3. The 30ml nicotinamide stock solution in the 3.MG Beauty Light bottle is firstly 4.5% boson, which is a patented anti-aging ingredient of L 'Oré al. Simply put, it can stimulate the synthesis of collagen and make the skin full and firm, so you see, it is different to lean on Ou Niangniang. Then, nicotinamide can whiten skin, caffeine can promote blood circulation, ethyl VC can whiten skin and resist oxidation, and finally salicylic acid can exfoliate and metabolize melanin. Does this look gorgeous?
4. UNISKIN Youshiyan #6.3 Anti-sugar Whitening Essence 30g This #6.3 Whitening Essence is the star product of Youshiyan's family, featuring 6% pro-Vitage, in which Albizia Albizia bark extract can resist sugar yellowing, grape vine extract can improve photoaging, and nicotinamide can whiten, brighten and fade spots.
We know that sugar molecules attached to protein can easily form glycated products AGEs, which will make collagen and elastin very fragile and make the skin dull, rough and slack. If the antioxidant system is weak, saccharified products are more likely to accumulate and stimulate the formation of melanin.
This whitening essence can achieve the purpose of whitening and anti-aging through the combination of anti-sugar and anti-oxygen. Known as the savior of the tea party, it was recommended by Li Jiaqi and Wang Feifei. The texture is translucent and curd-like, and it will turn into water drops after being wiped open. Moist and not greasy, it is quite suitable for oil skin.
You Yan Shijia also has a #5.2 Clear and Fading Essence Dew, the main component of which is nicotinamide, that is, melanin cannot be transported to the epidermis. Glycyrrhiza glabra can inhibit the production of melanin from the source, and cactus extract is actually a kind of botanical fruit acid, which can peel off old and waste keratin, thus basically covering the three ways of whitening, thus achieving the effect of whitening and lightening spots.

Finally, I want to say that it is very necessary to equip some whitening products in daily skin care products. Most whitening products can resist oxidation, inflammation and photoaging, even if they can't completely remove spots, they are essential as prevention. But whitening products are dazzling and confusing, so don't care too much about the price when choosing whitening products.
