There are a lot of people who will run up and ask me about the acid brush, and I will make a sneer with corrugated eyes [I don’t have that knowledge reserve.]
How to calculate that the knowledge reserve is enough? When you don’t need to ask others, it is enough.
The purpose of this article is to tell you that don’t do it yourself.

Is acid brushing really good for skin?
Now all kinds of skin care products manufacturers say that cutin on the face is [heinous]. All kinds of skin problems, cutin is the main culprit. Sisters of all walks of life regard cutin as the enemy of life and need to remove it quickly. The concept of [fruit acid for skin] [brush acid] is becoming more and more popular.
As long as it is acid brushing, it is like peeling the tree. The old bark of the tree is scraped off, and the new bark is fresh and smooth, but once the hand is confiscated, the bark is scraped off, and the scraped area will either grow a deformed tumor or rot off.
Brushing acid and exfoliating the skin on the face is really the same as peeling trees.
So what about what? Analogous to the analogy of bark peeling, the significance of exfoliating cutin lies in removing the old and exposing the new cutin. The new cutin must be young and tender, and the young and tender vision looks even if the skin is good.
Many girls who try to brush acid for the first time, brush acid for one night and wash their faces the next day, and their skin immediately looks better. But must this be a good thing?
Not necessarily.
The metabolic capacity of the skin is limited. When you brush acid indefinitely and constantly force the epidermis to metabolize, once the metabolic capacity of the skin cannot be sustained, the skin will first lose its protective barrier, become infected and inflamed, and the metabolic function of the skin will be disordered.
Maybe you brush acid for a week and a month, and you will be beautiful. Then you will have to spend several years or even the rest of your life to repay the slack and aging of your skin, because you do not have a healthy skin to resist the damage of ultraviolet rays and environmental pollution.
If you still don’t give up and want to reserve more knowledge to brush your acid, you can continue to look down:
What are the acids in skin care products?
Commonly used acids mainly include salicylic acid, tartaric acid and almond acid, which can penetrate into the interstitium of epidermal cells, affect the connection between cells and make keratinous fall off.
Salicylic acid
Salicylic acid has some obvious advantages over other acids. Salicylic acid is found in many products with oil control and acne removal formulas.
It is bioactive, fat-soluble and has appropriate molecular weight. Salicylic acid can mostly stay in the epidermis to play a role, which is easy to control. Due to its fat-soluble characteristics, salicylic acid can be dissolved in the oil secreted by the skin, penetrate along the pores, and clean up the lipid in the pores.
In addition, bacteriostasis can relieve the symptoms of acne and some of the pores are bulky.
The disadvantage of salicylic acid is also obvious, that is, it is difficult to make superior formula.
This is because salicylic acid is insoluble in water. To maintain its activity, many formulas currently use alcohol to dissolve salicylic acid.
Dissolution of alcohol will bring a problem. When the alcohol solution of salicylic acid is smeared on the skin, alcohol will evaporate rapidly, salicylic acid will remain on the skin in the form of crystals, and salicylic acid crystals are extremely stimulating.
At present, most salicylic acid-containing products on the market are either greasy in formula, alcoholic in flavor or very irritating to skin. Perfect products are very rare.
In the “Hygienic Standard for Cosmetics” issued by our country in 2007, salicylic acid is a restricted substance. In products such as toner, emulsion, cream and bath products that are not washed off, the concentration shall not exceed 2.0%, and the label must be marked [containing salicylic acid].
When you go to buy acne removal products, you must see clearly.
Tartaric acid
This component is commonly used in acid brushing trend and has two characteristics: small molecular weight; Water soluble.
- Because it is soluble in water, it is especially simple to make in the formula, so there are many fruit acid products on the market, and there are many tricks. However, the molecular weight is small. Compared with other acids, it is really easy to penetrate and difficult to control in use. Just like scraping bark, it will be scraped by accident and various skin problems will occur.
Fruit acid skin replacement is a very mature operation in medical cosmetology, also known as [Fruit Acid Chemical Exfoliation]. This is an operation with strict requirements. There are very strict regulations on the applicable population, solution concentration, residence time, postoperative care and frequency of use, in order to prevent skin problems and adverse consequences.
It’s really not that you can buy a bottle of high-concentration fruit acid skin care products at home.
In medical cosmetology, the key to changing skin with tartaric acid is not tartaric acid, but to make skin metabolism reach a more reasonable level under the intervention of medical means.
Attention, skin metabolism is the core, don’t fool around at home!
Almond acid is a special fruit acid with large molecular weight, fat solubility and less irritation than other fruit acids, so the concentration of almond acid products on the market is quite high.
However, as an acid product, it still has a lot of irritation. Therefore, China’s specifications require that the concentration of fruit acid products in cosmetics should not exceed 6%. If the concentration is greater than 3%, it is required to be marked [used at the same time as sunscreen products].
As far as I know, the concentration of several skin care products commonly used in the acid brushing field is mostly 10% ~ 15%. Although the concentration is lower than that of the solution used in the hospital [fruit acid chemical exfoliation], it also exceeds the national standard.
Everyone must be cautious and cautious. If you don’t have a detailed understanding of the skin care after acid brushing and don’t have the perfect equipment of the hospital at home, don’t do it yourself.
If you want to brush acid, whether you feel that your skin needs [skin change] or the shopping guide says you need it, please go to the dermatology department first. Don’t be lazy, listen to the doctor, save trouble, and the probability of bad face is much smaller.
