19 years old mixed skin. Purchase method: I bought it online, and pimples broke out as soon as I used it. I don't like it anymore.
By 25-year-old mixed leather purchase method: other channels, I don't know if I bought a fake or something, it will explode when I use it, and it has always worked! I have bought it for a long time, and there is still more than half of the bottle. Don't waste it What should I do with you? ...
27-year-old dry skin sensitive to sleep. Purchase method: from other channels, many bottles have been used. This is the last stock in the house. I use it with a recycling series, and the brightening effect is great, and the whitening effect is lost again and again. The cost performance is not high. Never give up the new version after using this bottle. If the whitening effect of the new version is still gone, then you are completely dead.
By Miss Yu, who is running, is 27 years old and has mixed skin. How to buy: In other channels, running out of a bottle has no magical effect. Summer is over and I still cry in the dark.
Composition analysis of small light bulb
1. Fermented extract (Pitra)
Pitera is a patented component of SK-II. It is a special liquid extracted by yeast during fermentation. Contains vitamins, free amino acids, minerals, organic acids, inorganic acids and other natural ingredients, which are indispensable for healthy skin. It has excellent moisturizing and special moisturizing function.
Pitera? Very similar to natural moisturizing factor (NMF) of skin, it is an important element to improve and maintain skin brightness, softness and smoothness.
Pitera is the core component of SK2, which is mainly introduced in the article "Fairy Water". Pitra may contain some organic acids with exfoliating effect, especially kojic acid (the contribution of Aspergillus in wine brewing). After use, the epidermis can be corroded evenly and slowly, showing a special effect of softening and brightening the skin, which can also be seen from the feedback from users.
However, long-term use may cause skin thinning and sensitivity. . Dry skin and sensitive skin with thin cuticle should not be used, and other skin should be used with caution.
2. Whitening ingredients (nicotinamide)
The conclusion that nicotinamide can whiten skin comes from an experiment: putting melanocytes in a Petri dish with a certain concentration of nicotinamide around it, and then finding that the secretion of melanin is reduced. . . It is concluded that nicotinamide can whiten skin.
Sounds like a very reliable whitening ingredient. But when I think about it carefully, I feel wrong. Take drugs as an example. If all drugs adopt this experimental method, do you dare to use it? . . . Drugs are to be tested in human clinical trials, that is, to find a group of volunteers to take orally or externally for a certain period of time to observe the efficacy and side effects of drugs. . . If the curative effect is good and the side effects are small, it can be further produced and sold.
Do you understand a little? Nicotinamide has no human clinical trial report, so the so-called whitening effect should be quoted. . .
From the feedback of users, most people don't feel that the skin turns white or the spots become lighter, which also proves that nicotinamide is difficult to whiten.
