When used correctly, medial peels demonstrate excellent clinical efficacy in the treatment of fine lines, chronic actinic photodamage, superficial hyperpigmentation disorders (e.g., melasma), superficial acne scars.

Medium peels are used for facial rejuvenation, as they start intensive regeneration processes.

On estet-portal.com read which acids are used for median peels, as well as the correct technique for this procedure.

Is trichloroacetic acid effective for medium peeling

The original reference for medium depth chemoexfoliation was 50% trichloroacetic acid (TCA) solution.

TCA used at higher concentrations has a relatively high risk of complications, including dyschromia, scarring, sometimes bacterial superinfection, and herpes simplex virus reactivation.

Thus, the use of only one exfoliating agent in the form of highly concentrated TCA (> 50%) has fallen out of favor today.

The most common chemical agents currently used for medium depth peels are 70% glycolic acid and 35-50% TCA, with or without adjuvant combination products (e.g., Jessner's solution or solid carbon dioxide).

Combined median peeling: advantages of the technique

Higher concentrations of acids, layered application will produce deeper chemical peels. Therefore, it is preferable to carry out peeling in two stages:

  1. Pretreatment (e.g. Jessner's solution or solid CO2);
    2. Follow-up acid peel
  2. at a lower concentration (e.g. 50-70% glycolic acid or 35% TCA).
    3. These combination treatments provide
more even and controlled peeling

and reduce the incidence of dyschromia and scarring. Follow us on

Instagram! Applying Jessner's solution or solid CO2 with acetone before glycolic acid or TCA results in a more

uniform breakdown

of the epidermal barrier and a more thorough removal of natural oils from the skin. This allows acids to penetrate deeper into the skin. Medium Peeling Technique

Medium depth peels are often performed with

mild pre-procedure sedation. 

For medium depth peels correct application technique is critical to avoid unnecessary, unintentional reapplication of excess solution.

"frost" Level II-III. 

When using glycol and TCA peels , keratocoagulation will continue as long as the peeling agent remains on the skin. Completion of the reaction is achieved by neutralization with an alkaline agent such as sodium bicarbonate. Careful peeling technique and observation of procedure time and clinical signs of completion of the reaction (eg, erythema and icing) are essential to the safety of the procedure.

It is important to note that the neutralization of any acid with any base is
exothermic

; thus, during neutralization, patients may experience a temporary increase in the sensation of mild warmth, burning or tingling in the treatment area.

After a median peel, there may be

edema, erythema and desquamation.  

The nuances in concentration, different types of combinations and treatment methods can be adjusted depending on the phototype and skin condition of the patient. More useful information on our
