Atrophic scarring is caused by the loss of collagen that occurs in the inflammatory process of acne. All scars have psychological consequences, as they can affect self-esteem and cause physical pain when moving the affected area. Chemical peels are widely used to treat acne and acne scarring. They cause an injury to the skin or accelerated exfoliation, induced by caustic agents that cause controlled damage, followed by the release of cytokines and mediators of inflammation, resulting in thickening of the epidermis, collagen deposition, reorganization of structural elements and increase in dermal volume. Among the therapeutic modalities of acne scars, subcision is a simple and safe procedure. Subcision frees the scar surfaces and induces the formation of connective tissue directly below the scar. Another method used is the application of plasma rich in platelets and fibrin that release growth factor, essential for wound healing and synthesis of extracellular matrix remodeling. Polydioxanone (PDO) threads induce collagen production, increasing the number of fibroblasts in the tissue where it was inserted. This work presented a case of acne scarring, firstly treated with two applications of 10% ATA peeling and 10% retinoic acid. Then a subcision was made with a duckbill cannula and insertion of PDO wires with PRP in the scar region.
