Classification of the various types of peeling
- Very superficial peeling: removes only the superficial horny layer.
- Surface peeling: creates necrosis of part or all of the epidermal layer reaching the basal layer of the epidermis.
- Medium depth peeling: creates necrosis of the epidermis and part of the papillary dermis.
- Deep peeling: produces necrosis of the epidermis, papillary dermis and can extend to the reticular dermis; the chemicals used are: retnoic acid, 5-Fluorouracil (5-Fu), Jessner's solution, resorcinol, salicylic acid, trichloracetic acid, a-hydroxy-acids, a-keto-acids (pyruvic acid), phenol.
The depth of the peeling depends on numerous factors, such as:
- the type of substance used;
- the concentration of the substance used;
- the number of passes with the chosen substance on the same area of skin;
- the application technique;
- the preparation of the skin in the phase preceding the treatment;
- the type of skin treatment in the period preceding the peeling;
- the type of skin of the patient;
- the area of skin treated;
- the exposure time of the chosen chemical agent on the skin.
Considering all these variables, it is natural to understand that any classification relating to the various types of peeling cannot be classified mathematically, since, with the same substance, it is possible to obtain a superficial result on a certain type of skin, and on a another subject a deeper peeling.
Of course, the experience, competence and sensitivity of the doctor are indispensable conditions for the success of the therapy.
