1, UNISKIN excellent vision #5. 1. Looking at the ingredients alone, you prefer this one among several essences of Youshiyan. In addition to the favorite 377, there is amide amine, officially known as Sepiwhite whitening factor, and its chemical name is undecenyl phenylalanine. Forget it, let's call it amide.
Amide can block the signal tyrosinase of melanin production and inhibit melanin production from the source. ProX, a small white bottle of Olay, also added this ingredient. In addition, there is also a skin cleaning ingredient-condensed acid, whose main function is to prevent melanin accumulation and reduce pigmentation. Finally, there are oil-soluble VC derivatives, which, together with other ingredients, enhance whitening and antioxidant effects.
2. Canil Garnier377 Full-effect Instant Whitening Essence 30ml To be the king of 377 whitening products, we have to mention this 377 Full-effect Instant Whitening Essence from Canil. In addition to 377, there are nicotinamide, ethyl VC, lemon essence, pomegranate peel extraction and so on. Seeing the ingredients is quite touching. It can be seen that Canil, as a cockfighting in the essence of parity whitening, is by no means empty talk.
However, I need to remind you that this bottle of Canil is rich in essence, and with the third-ranked alcohol, the essence MS has also been added a lot, so the irritation is not low. Personally, I suggest oily tolerant skin, and sensitive muscles are best avoided. Compared with the old version, the texture of the new version is much fresher, and the skin feeling of oily skin or mixed skin should still be ok.
3. Peptide amido (isobutyl thiazolyl resorcinol) sulfhydryl peptide amido is a patented whitening ingredient researched by Beiersdorf Group for many years. Its molecular weight is 278, which is known as the strongest whitening component on the surface. It can act on the first step of whitening and prevent the production and activity of tyrosinase. In fact, as long as you look for resorcinol, it is basically a whitening ingredient with strong effect. Like peptide amino, when the concentration reaches 0.2%, it has excellent speckle reduction effect.
4. Youselin Clear Spot Essence (Baiyaoguan) In addition to the main component peptide Amydol, Youselinguan also added sodium ascorbate phosphate SAP, which can act on the second link of whitening spots: antioxidation. In addition, there are licorice, glucoside, isoquercitrin and so on. So as to enhance the antioxidant and free radical scavenging effects. Among them, isoquercitrin can not only resist oxygen, but also play an anti-inflammatory and analgesic role. There is also hyaluronic acid with large and small molecules in the small double tube, which is mainly used for moisturizing, but this macromolecular hyaluronic acid is easier to rub mud, otherwise it will be perfect. I actually like this essence.
Another thing to say here is that the small double tube lacks targeted components in the reduction and metabolism of melanin and does not cover all the pathways of whitening. It may not be a comprehensive whitening essence, so the official positioning of it is a bottle of freckle essence. It should also be reminded that Yosemite small double tubes contain alcohol, essence and preservatives, and the smell of alcohol is quite high, so it is best to try a sample of sensitive muscles first.
There is Selin and a stylus, which is the same as a small double tube. If you want to dilute the spots locally, then I personally recommend using a light spot pen to smear them, which is more targeted, and secondly, you don't have to worry about rubbing mud. It's perfect.
