After reading the above passage, many people still don't understand what brush acid is. Let me give you an example. I don't know if you have done foot membranes:

Look at the pedal:

Foot film is actually a non-woven fabric soaked in high concentration acid solution and made into the shape of socks. Usually apply it for ten or twenty minutes at a time like a mask. After several or more smears, the feet will peel off obviously, like this:

With the gradual completion of peeling, calluses and dead skin are peeled off, and the feet become tender, smooth and white.

The above process can be understood as brush acid's principle.

Of course, the facial brush acid can't be as "violent" as the foot membrane, and the facial brush acid process "comes slowly". It will not directly tear off a layer of skin like a foot, but will promote the metabolism of old waste cuticle more slowly and gently, and generally will not be peeled off with the naked eye.

Look, brush acid is meticulous as a whole, not trying to "close" that pore.

The first one is to go to a beauty salon, which is often called fruit acid skin rejuvenation. You should use high-concentration fruit acid products, such as 15%-75% or even higher, with high concentration and high risk. Be sure to go to a beauty salon and find a professional beautician to do it. You must not brush it privately.

Use high concentration of fruit acid products:

The general steps of fruit acid skin-changing:

As can be seen from the above steps, fruit acid peeling is very professional and operable. Everyone has different skin types and different problems, which concentration of fruit acid should be used, how long to apply it, when to neutralize it and so on. And there must be professional norms, which also has a lot to do with the experience of operators.

Not everyone can use fruit acid to rejuvenate the skin. First of all, test the skin to make sure that the skin tolerance is acceptable (the stratum corneum is too thin, so sensitive muscles must not be brushed), and then give you brush acid, which is usually brushed once every 4-6 weeks. During the process, there will be accompanying reactions or side effects such as skin explosion, peeling and acne explosion. The beautician must give a follow-up care plan in time to prevent uncontrollable consequences, which is one of the reasons why you should not go to brush acid privately.

Generally speaking, beauticians will gradually increase the concentration of brush acid. After changing skin with fruit acid every time, there are many precautions, including how to protect skin and how to clean it. Pay special attention to sun protection to prevent ultraviolet rays from burning the skin.

I often see some sister papers secretly "purchasing" some highly concentrated fruit acid products and keeping them in brush acid. This is actually a very risky behavior. I hope you don't follow suit.

Daily maintenance of brush acid actually has nothing to do with "brushing". It uses low-concentration acid-containing products, and some are low-concentration acid solutions (generally, the concentration of acid does not exceed 6%, and the concentration of salicylic acid does not exceed 3%). There is no need for special care like acid rejuvenation, and there is no need for neutralization. It is as simple and convenient to use as ordinary emulsion.

Daily maintenance of brush acid is much safer than professional fruit acid skin replacement, and there are few allergic reactions. The disadvantage is that it is slow to take effect and needs to be used consistently.

As you can understand, the daily maintenance in brush acid is broken into parts, the fruit acid is peeled once a month, and the daily maintenance in brush acid is used once in the morning and once in the evening. After one year, the skin will be obviously improved. From the perspective of skin care, brush acid's daily maintenance is more in line with the principle of slow work and fine work.

But fruit acids are actually a big category, including glycolic acid, malic acid, tartaric acid, citric acid, lactic acid, mandelic acid and so on. Different kinds of acids have different effects, and different concentrations of the same acid have different effects:

These acids are difficult for ordinary people to understand and unnecessary. You can directly use lazy compound fruit acid milk, which is composed of a variety of fruit acids. It is enough for general skin problems such as closed mouth, thick pores and thick cuticle.

Lazy compound fruit acid milk is mainly simple to use and can be used like ordinary emulsion. Generally speaking, after a period of time, the skin will become softer:

In addition, fruit acid milk also helps to improve the closed acne caused by thick keratin and blocked pores, which helps to soften and block keratin and dredge pores.

Besides brush acid, fine pores need all-round efforts, not just one kind of effort.

For example, when you were in brush acid, you went to the plateau to herd sheep. The water of Guanyin bodhisattva is hard to use when the wind blows and the sun shines.

Therefore, for skin with large pores, there are still many daily precautions, especially oil control+hydration+anti-aging.

Because the skin is moist and full, the pores are visually smaller, which is also helpful for meticulous skin.
