At one time, the concept of "rejuvenation" was very popular. Fruit acid peeling is one of them.
But now, when people talk about fruit acid, what they can think of is: irritation, skin thinning, allergies and even disfigurement. This is because, over the years, many people have accepted unprofessional fruit acid "skin rejuvenation", and the operator can't tell the concentration, cortex and dosage, which leads to scars instead of beauty.
In fact, fruit acid is recognized as a good cook in the medical and aesthetic circles, which can cure acne, fade spots and improve fine lines. But beauty is not the premise of disfigurement, but the proper use.
Cleopatra used fruit acid.
It can be said that fruit acid is one of the really effective ingredients in the field of cosmetics at present.
The use history of fruit acid can be traced back to more than 2000 years ago. Legend has it that Cleopatra is an expert in skin care, who loves to bathe with milk and wash her face with wine. At that time, people didn't know why milk and wine could whiten skin. Until 1974, American dermatologist Scott and Chinese-American chemist Dr. Yu Ruijin found that fruit acid had a significant effect on treating skin diseases and resisting aging. Lactic acid in milk and tartaric acid in wine are both fruit acids.
Since then, fruit acid has become famous. In the early 1990s, fruit acid was praised as the most magical product for skin care and beauty.
Fruit acid, abbreviated as AHA, is actually the general name of many chemicals, and their chemical structures all contain hydroxyl groups. Because most of them can be found in natural fruits, they are collectively called fruit acids.
Besides lactic acid and tartaric acid, there are glycolic acid extracted from sugarcane, malic acid extracted from apples, mandelic acid extracted from almonds and citric acid extracted from citrus fruits.
Professor Hu Kuikui introduced that the role of fruit acid in skin beauty or treatment includes the treatment and daily maintenance of skin aging. "Fruit acid can promote skin metabolism, promote the synthesis of collagen and hyaluronic acid, and significantly improve skin aging, such as fine lines, roughness and large pores."
Can be used for treating acne, improving acne and micro-acne skin, removing post-acne pigmentation, improving acne scar, and regulating oil secretion by promoting the exfoliation of the outermost aged stratum corneum and dissolving keratin plugs accumulated at the hair follicle mouth, especially suitable for mild and moderate acne.
Can remove spots, "fruit acid has a strong whitening effect and brightens the skin color, so it can be used for the treatment of chloasma, sunburn and post-inflammatory pigmentation, which can improve uneven skin color and eliminate dull skin color".
It can also treat various skin diseases, such as ichthyosis, fillet disease, amyloidosis of skin, erythema and melanosis of face and neck, etc. These diseases are characterized by dry and rough skin, keratinized papules and so on. This greatly affects the appearance, but there is no very effective and safe treatment. The appearance of fruit acid has brought beauty and hope to these patients.
A beauty salon is definitely not a place where you can "change your skin"
Hu Kuikui told reporters that fruit acid skin rejuvenation is called "chemical skin rejuvenation" in medicine. The word "peeling" is scary.
Fruit acid can be divided into first generation fruit acid, second generation fruit acid and third generation fruit acid. Different kinds of fruit acids and different concentrations of fruit acids have significant differences on the skin. Among them, the first generation of fruit acid can play the role of changing skin, that is, peeling and changing skin.
The first generation of fruit acid includes more than twenty different substances, different substances have different characteristics, different substances have different concentrations and different functions.
"The concentration of fruit acid is more than 20%. The indications, treatment timing, treatment concentration and the ratio of different kinds of fruit acids should be strictly controlled during operation. During the operation, we should race against time, closely observe the treatment reaction and terminate the treatment in time, otherwise chemical burns may occur. Therefore, fruit acid skin rejuvenation must be used by experienced medical staff and carried out in hospitals and beauty institutions with medical qualifications. "
The first-generation fruit acid with the concentration below 10% can be used as household products.
However, Hu Kuikui reminded that low-concentration first-generation fruit acid is still irritating to the skin, and some people's skin will not adapt, so it should be used under the guidance of a specialist.
The second-generation and third-generation fruit acids belong to household skin care products, which have the functions of moisturizing and repairing, and have a mild effect, but they do not have the function of changing the skin. "You can use it at home or in a beauty salon. But so far, the patents of the second-generation fruit acid and the third-generation fruit acid still belong to Maxim Cui Company, and its products are positioned as medical skin care products, which are only sold in hospitals and beauty institutions with medical qualifications. "
Hu Kuikui said that although the second and third generation of fruit acids are safe and can be purchased by themselves, it is still recommended to consult a professional doctor and use them reasonably, so as to exert the greatest effect of fruit acids from the supporting process of skin rejuvenation and overall skin care.
Regular course of treatment is 4~5 times, not once and for all.
What kind of feeling is it to make fruit acid to change skin?
"Fruit acid is an acidic substance with slight exfoliation, so it is slightly irritating to the skin. There is a brief tingling and burning sensation after being applied to the face, which usually disappears within a few minutes after the end. After treatment, there may be slight desquamation or even scabbing, and it feels dry and rough for several days. "
Hu Kuikui said that general treatment 1~2 times can see the curative effect. If the effect is obvious, it is recommended to treat according to the course of treatment. The routine course of treatment is 4-5 times with an interval of 3-4 weeks. After fruit acid treatment, the skin returned to normal in about 5~7 days. Treatment can be repeated every 1~2 years.
Fruit acid peeling is not a once-and-for-all thing. Hu Kuikui said that after changing skin with fruit acid, problems such as photoaging, acne, pigmentation and large pores can be significantly improved, and then the skin will continue to age on this basis. Therefore, continuous maintenance is needed to maintain a good state of youth for a long time.
Therefore, she suggested that some second-generation and third-generation fruit acid household products with moisturizing and repairing functions can be generally used, and the skin rejuvenation course of fruit acid can be repeated every 1~2 years.
As far as she knows, the manufacturers of fruit acid are different, the varieties are different, the concentration is different, and the supporting household products are also different, so the cost varies greatly, generally ranging from several hundred yuan to several thousand yuan at a time.
Side effects you need to know: burns, dryness, easy sunburn.
The reason why it is emphasized that you should be cautious in making fruit acid skin-changing, and you should do it in an institution with medical qualifications, is because once the operation is improper, the consequences will make you regret, and you would rather have such a "rough" face.
The most serious side effect is skin burns. This is related to the concentration of fruit acid. It is characterized by skin congestion, edema, flushing, burning pain, running water and desquamation. If it is not well controlled, infection may occur, or even fester and scar.
In addition, when the fruit acid peels off the aged stratum corneum, if the peeling degree is too deep, it will damage the stratum corneum of the skin, leading to the decrease of the water-locking function and defense ability of the skin, and it is easy to appear dehydration, drying, peeling and other phenomena.
In addition, Hu Kuikui said that after a period of treatment, the skin's sensitivity to ultraviolet rays has increased, so it is necessary to do a good job of moisturizing and sun protection, avoid external products that may be irritating, and avoid strong friction.
Professor Hu Kuikui reminded that people in the following situations are not suitable to try fruit acid rejuvenation:
● Locally active herpes or wart virus infection.
● Fungal infection, bacterial infection, allergic diseases, etc. They are all local.
● There are fresh wounds healing in the skin changing area.
● Sensitive skin
● Recently received radiotherapy.
● Those who can't cooperate with postoperative care for sun protection
● People who have unreasonable expectations for treatment.
