Brush acid refers to changing the acidity of the skin surface, helping to remove excess waste keratin and promoting the normal metabolism of skin cells. Brush acid's principle is to use skin care products with a certain concentration of acidic ingredients to remove the closed mouth, blackheads and thick cuticles on the face, as well as dry lines, fine lines and uneven skin color formed after aging, which is equivalent to corroding the skin surface, promoting metabolism and dredging pores.
There are salicylic acid, fruit acid and A acid in brush acid. Brush acid's premise is that the skin barrier is healthy. If the skin is sensitive, it is best not to use brush acid. If your skin is healthy, you have some special skin care demands, such as brightening skin tone, keeping your mouth shut, acne and blackheads can be improved by brush acid, but again, brush acid should be careful and do his previous homework well.
Matters needing attention in brush acid:
Brush from a low concentration and gradually build up tolerance. Don't take strong medicine for the first time in brush acid, otherwise it will be counterproductive, not only failing to improve the skin condition, but also damaging the skin barrier. Dry skin should be moisturized before brush acid to reduce the irritation of acidic components to the skin. In case of intolerance, redness and allergy, it is recommended to stop using it immediately and seek medical attention immediately.
It's best to do it at night in brush acid and have strict sun protection in brush acid the next day. In addition to applying sunscreen products, you should also do hard sunscreen, such as umbrella and hat. The most direct reaction of skin after brush acid is dryness, so the moisturizing work after brush acid must keep up.
Brush acid frequency should not be too high. Often brush acid is wrong. If you are not careful, you may ruin your face. Generally speaking, dry skin can be done once a month, and oily skin can be done a little more frequently, once every two weeks.
