Under stimulation, it can promote the production of skin collagen and the metabolism of skin pigment, and play an anti-aging and whitening role. Therefore, fruit acid is widely used to remove acne, shut up, shrink pores and remove blackheads, and it is also a common dish in beauty salons for anti-aging and whitening. It means that you need to go to a beauty salon to do the brush acid project, and it should be operated by professionals. Medical beauty generally uses fruit acid with relatively high concentration, which takes effect quickly, but it is also expensive. And don't superimpose similar products when you are in brush acid (for example, after you brush the acid, it happens that your toner also contains acid, so you must avoid it to avoid intolerance).

Not everyone is suitable for brush acid, so girls should not just look at the market as if brush acid is very popular and buy it. You just have a pimple on your face. Please don't use it. Before use, you can use water emulsion as the base. Sensitive muscles must use water emulsion as the base, but remember that it is simple and ineffective water emulsion. If the emulsion in water contains anti-acne ingredients, essence and preservatives, the penetration promotion of salicylic acid may lead to organic solvents such as alcohol, ethanol and ethyl acetate in glycolic acid, which are slightly soluble in ether and insoluble in hydrocarbons. It has the duality of alcohol and acid, and decomposes when heated to boiling point. Used in organic synthesis and so on. Citric acid extracted from oranges and other citrus fruits also belongs to glycolic acid. Hydroxyl has a strong water absorption capacity, and at the same time, it can promote the generation of natural moisturizing factors after penetrating into dermis, so it can moisturize. Because its permeability is obviously related to concentration, the higher the concentration, the longer the residence time, the stronger the permeability and the stronger the effect. Its absorption rate exceeds the standard.

The second function of acid is whitening. The principle of action is to reduce the attachments on the epidermis of your skin and promote cell metabolism. But remember not to visit brush acid often, because your skin is very fragile, unlike steel. I have to find a professional skin management. If I want to stay in brush acid in order to save all kinds of service fees, I must control the time when I am in brush acid, and I must do a repair after brushing to avoid other skin conditions.
