What are chemical peels, how often they need to be done and whether pigmentation can appear after, says Rosa Gerliani, dermatocosmetologist at the DMC Center for Innovative Medicine.

Dermatologist explains who urgently needs a chemical skin peel

Chemical peeling is based on the effect of acids on the skin, which not only remove the stratum corneum of the epidermis and excess sebum, but also have a stimulating effect. No cleanser from the everyday skin care range is able to give such an intense effect.

There are three types of chemical peels depending on the depth of action:

  • Surface. These are delicate peels that cleanse the top layer of the epidermis. As a rule, they are absolutely atraumatic, that is, they do not require special training and a rehabilitation period. They can be done all year round. But they do not give a wow effect. The key advantage of such peels is that they allow you to comfortably maintain the result after more serious beauty procedures and prevent unwanted skin changes.
  • Median. In such peels, acids are able to penetrate to the depth of the dermis, providing a more pronounced effect on the skin. After such a peeling, there is a rehabilitation period that requires special care, since the process of restoration and transformation of the skin is accompanied by its peeling and sometimes redness.  
  • Deep. These are procedures with a highly noticeable effect, which can even out pronounced scars and post-acne on the skin, significantly lighten pigmentation or remove it completely, reduce the depth of wrinkles and, in general, noticeably rejuvenate the face. Acids in such peels affect the lower layer of the dermis. Rehabilitation after them requires constant monitoring by a doctor.

The most popular are superficial and median peels. With their help, you can:

  • reduce the depth of wrinkles and scars;
  • get rid of uneven terrain;
  • correct hyperkeratosis;
  • prevent acne and pimples;
  • clean and narrow pores;
  • eliminate traces of photoaging;
  • prepare the skin for more intense treatments.

Skin pigmentation after peeling is a possible but rare occurrence. Most often it is associated with non-compliance with recommendations for care during the rehabilitation period. Since chemical peeling is inherently a skin burn, it requires careful treatment during the recovery period. First of all, sun protection with products with an SPF of at least 30, and preferably 50. If you do not apply the product on the skin or do not renew it for a long time, then the skin damaged as a result of peeling is exposed to additional ultraviolet radiation, which provokes the development of pigmentation.

During the rehabilitation period after peeling, it is not recommended to visit the bathhouse, solarium and swimming pool, as well as being in the open sun, since in such conditions the risk of infection of sensitive and damaged skin increases. Elevated temperatures also interfere with tissue repair after the procedure.

In order for the peeling to have the desired effect, it is important to take some measures before the procedure. For example, do not drink alcohol, since the interaction of acids and alcohol can cause burns and swelling, excessive redness of the skin and pigmentation. And if your plans do not include the fight against serious "problems" of the skin, then you can use home remedies for cleansing.

To refresh the skin, prevent acne or early age-related changes, 1-2 superficial chemical peels per month are enough. If it is necessary to solve the problem of pronounced skin defects or intensively tone up aging skin, then a median peeling is recommended once every six months.
