TCA is an organic acid which, when applied to the skin, causes the targeted denaturation of proteins. This leads to the controlled removal of the upper layers of skin (exfoliation).<\/p>\n\n<p class=\"wp-block-paragraph\">This triggers a powerful wound-healing and regenerative process, which leads to the formation of new collagen and elastin and, consequently, to smoother, more even and firmer skin.<\/p>\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/4beauty.de\/en\/service-information\/contact\/\">Contact us for a no-obligation enquiry<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"das-wirkprinzip-eine-kontrollierte-verletzung-fur-eine-bessere-haut\">How it works: A controlled injury for better skin<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The principle behind a TCA peel is to trigger a healing response. A controlled chemical injury is inflicted on the skin to force it to regenerate itself into a better, healthier state.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Replacement:<\/strong> The acid breaks down the bonds between the old, damaged skin cells, causing the outermost layers of skin to peel off in the days following the treatment.<\/li>\n\n\n\n<li><strong>Recovery:<\/strong> The body responds to this \u201einjury\u201c by producing new collagen and elastin \u2013 the basic building blocks of firm and supple skin.<\/li>\n\n\n\n<li><strong>Result:<\/strong> The new skin is fresher, smoother, more evenly pigmented and has a finer texture.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"die-starke-des-peelings-entscheidet-oberflachlich-bis-tief\">It all comes down to the strength of the exfoliant: from superficial to deep<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The key factor in a TCA peel is the concentration of the acid used by the doctor. This determines the depth of penetration and, consequently, the intensity of the peel and the length of the recovery period.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Exfoliation depth<\/th><th>Superficial<\/th><th>Medium-low<\/th><\/tr><\/thead><tbody><tr><td><strong>TCA concentration<\/strong><\/td><td>10\u201320 %<\/td><td>25\u201335 %<\/td><\/tr><tr><td><strong>Penetration depth<\/strong><\/td><td>Only the outermost layer of skin (epidermis)<\/td><td>Down to the upper dermis<\/td><\/tr><tr><td><strong>Ideal for\u2026<\/strong><\/td><td>Dull complexion, fine lines, mild acne<\/td><td>Pronounced wrinkles, acne scars, pigmentation problems, sun damage<\/td><\/tr><tr><td><strong>Downtime<\/strong><\/td><td>Short (approx. 5\u20137 days)<\/td><td>Significant (approx. 7\u201314 days)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"608\" height=\"576\" src=\"https:\/\/4beauty.de\/wp-content\/uploads\/2026\/08\/2025-12_tca-peeling-ablauf.svg\" alt=\"Diagram: TCA peel process\" class=\"wp-image-374 size-full\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<h2 class=\"wp-block-heading\" id=\"der-ablauf-was-sie-beim-tca-peeling-erwartet\">The procedure: What to expect from a TCA peel<\/h2>\n\n<p class=\"wp-block-paragraph\">A TCA peel is a multi-stage process that requires careful preparation and aftercare.<\/p>\n<\/div><\/div>\n\n\n\n<ol class=\"wp-block-list is-style-step-list\">\n<li><strong>Preparation (2\u20134 weeks in advance)<\/strong> A special cream (e.g. containing vitamin A acid) is often prescribed to prepare the skin for the peel and ensure an even result.<\/li>\n\n\n\n<li><strong>The treatment (at the surgery)<\/strong> The skin is thoroughly cleansed and degreased. The doctor then applies the TCA solution. This may cause a burning sensation. A typical sign that the reaction is proceeding correctly is \u201efrosting\u201c \u2013 a temporary whitening of the skin.<\/li>\n\n\n\n<li><strong>The recovery period (at home)<\/strong> This is the most intense phase. The skin is very red, feels tight and begins to peel over a large area after 2\u20133 days. It is <strong>absolutely crucial<\/strong>, do not peel the skin off manually to avoid scarring. It must be looked after using special creams.<\/li>\n\n\n\n<li><strong>Post-operative care (weeks to months afterwards)<\/strong> The new skin is initially rosy and extremely sensitive. Exfoliation can make the skin appear lighter (bleaching effect). A daily, high <strong>Sun protection (SPF 50+) is therefore essential for at least 3 months<\/strong>, to prevent patchy darkening (post-inflammatory hyperpigmentation).<\/li>\n<\/ol>\n\n\n\n<div class=\"wp-block-media-text has-media-on-the-right is-stacked-on-mobile\"><div class=\"wp-block-media-text__content\">\n<h2 class=\"wp-block-heading\" id=\"risiken-und-die-bedeutung-der-absicherung\">Risks and the importance of insurance cover<\/h2>\n\n<p class=\"wp-block-paragraph\">A TCA peel is highly effective, but it is not without risks.
