Treatment of sunken acne scars
Inflammations or injuries that reach into the middle layer of the skin (dermis) can lead to scarring. Scratching or squeezing inflamed areas or pimples further encourages scarring. Scars can be thickened/protruded (hypertrophic) or retracted (atrophic). Typical retracted scars are the so-called “boxcar, rolling or ice-pick scars”. These can be treated efficiently with TCA (trichloroacetic acid) peeling.
Trichloroacetic acid is an acid which, depending on the concentration, has a more or less strong peeling effect and penetration depth into the skin. It dissolves the upper skin cells (keratinocytes) and leads to clumping (coagulation) of the skin proteins. A local inflammation is triggered, which leads to the formation of new collagen. This leads to a reduction in scar depth.
On average, 3-6 treatments are necessary (depending on the scar depth) at intervals of at least 4 weeks. An improvement in scar depth of 10-40% can be expected with each session. Exactly how many treatments are needed cannot be predicted. This depends very much on the skin type and how the therapy responds individually.
TCA peeling should only be done on untanned skin and it must be followed by consistent sun protection. Preferably, therefore, this treatment takes place in the winter months.
The procedure of a TCA peeling.
First, the skin is disinfected and degreased. In contrast to other peeling procedures, which are applied to the entire surface, the highly concentrated trichloroacetic acid is applied selectively to the depressions during the so-called TCA-Cross (Chemical Reconstruction Of Skin Scars)-peeling. During application and for a few minutes afterwards, the skin is cooled with a cooling device to relieve discomfort. A wound healing cream and sunscreen are then applied.
