Why do acid peels cause acne? Why do we need to use sunscreen when we peel acid peels?

There are many benefits of acid peeling, and it is also a very popular and beloved skin care method. One of the biggest effects of acid peeling is to thin the stratum corneum. When the stratum corneum becomes thinner, the skin will become more sensitive and irritated.

The characteristics of acid are to accelerate the shedding of keratin, regulate oil, and promote metabolism. Therefore, it is a good helper for unclogging pores. There are two reasons why you get acne when you use acid. One is that you choose the wrong acid, and the second is that you use it in the wrong way. Because we say that one of the types of acne is: when you do a skin slice, you can see that there are micro-acne deep in the hair follicles, all in the bottom layer of the skin. When you use acid, the keratin falls off, and the micro-acne will naturally come out. After they come out, they come into contact with the air and the wound is not well cared for, so they will naturally be infected with acne bacteria, thus forming acne. When brushing acid, it takes 2-3 days to observe and then adjust the dosage. Some people have a great reaction to acid, while some people have no reaction. So if you have a lot of acne, it is recommended to use it under the guidance of your nurse or dermatologist. Otherwise, the acne will break out, and the gain will outweigh the loss. In addition, A acid and salicylic acid are very irritating, so they are very uncontrollable. Then, fruit acid is relatively mild, and mandelic acid has the least molecules and is the mildest among fruit acids. And it can't thicken the dermis. The acid regenerates the collagen in the dermis to achieve a rejuvenation effect, which is also one of the anti-aging ingredients. However, it is also an acid after all, so you must be careful when using it. Excessive use really leads to symptoms of chronic dermatitis and contact dermatitis. Acne is generally red and swollen pustules or whiteheads. If you can clean it, it will get better faster if you use a professional needle to clean it (it is best to find a professional to do the needle cleaning, and do a good job of disinfection and anti-inflammatory). If you don't know how to do it, just be honest and don't touch it. You will regret it if you squeeze it with your hands and leave acne scars and acne pits. In addition, red and swollen acne requires anti-inflammatory and antibacterial, so it is better to use it with anti-inflammatory and antibacterial drugs. For example, Bansai, clindamycin, metronidazole, azelaic acid, etc. It is best to follow the doctor's advice on which one to use. These drugs can also be used alternately, but even if they are used alternately, they will take a few days or two weeks. Don't say it's ineffective if you don't see much reaction after using it for one day. If the drug works so quickly and so obviously, would you dare to use it?

Acid peeling is to use a certain concentration of acid to promote the exfoliation of the stratum corneum, help remove old dead skin cells, speed up the metabolism of the skin, and thus create a new healthy stratum corneum. Sensitive skin and thin skin do not need to consider acid peeling at all. Acid peeling must ensure that the skin is healthy enough. Pay attention to sun protection during acid peeling. Acid peeling causes the old dead skin cells on the face to fall off, and new cuticles have not yet been fully generated. The protection of the skin is relatively weakened, and the damage of ultraviolet rays will be more direct. The effect of acid peeling is obvious, but you must not be greedy. Acid peeling will bring obvious changes to the skin, but too fast a frequency will cause skin damage. Salicylic acid is very effective for blackheads, closed comedones. A acid is effective for large closed comedones, pustules, papules and even chicken skin, but this is a drug, it is best to use it under the guidance of a doctor. Azelaic acid, TO has this, whitening and anti-inflammatory, acne skin can be used, but it is relatively mild and not so obvious. Fruit acid, 3% can moisturize, and 4% can peel the stratum corneum. High concentrations of fruit acid can cause damage to the skin, thinning the skin and even burns. Four days before acid peeling, soak a cotton pad and wipe it locally after cleansing. If you are particularly sensitive, use it every other day, and then follow normal skin care, focusing on moisturizing. If there is no abnormal feeling, you can apply a local wet compress every day for less than ten minutes. Generally, a cycle is half a month to twenty days. If the effect is achieved earlier, you can stop, and the longest should not exceed twenty days. Oily acne skin can be acid-peeled within the time range, and dry skin is best within fifteen days. There should be at least one month between two acid peels.

If you choose to use acid peeling, you must insist on using it, use it at night, and use sunscreen during the day. It should be used for at least three to six months. If your acne is particularly severe, you can take Tels or Sanrui capsules orally, and you must take them for more than three months. But young ladies who are planning to have a child should never take it. I emphasize again that acid peeling will not work for a week. And if you don't stick to it after using it, and use it every three or five days, this will certainly not cure acne. Generally speaking, A acid treatment takes about three to six months, or even longer. But the time is fast enough for treating acne, so don't believe in products that can get rid of acne in just a few days. You must insist on using it even if it causes redness and peeling. And you must avoid using extra skin care products during use. You must also go to the hospital for follow-up visits regularly.

① Oily skin has strong oil secretion. Excessive oil cannot be metabolized, clogging pores and causing acne. Unclog pores and restore normal skin metabolism

② The stratum corneum grows too fast, the skin metabolism is slow, and old keratin accumulates, so as to achieve the effect of removing keratin.

③Acid can reduce inflammation to achieve the effect of removing acne

④Low concentration of fruit acid has whitening effect
