      Acne vulgaris je dugotrajno stanje kože koje uzrokuje razne vrste prištića poput mitesera i cista. Ako se ne liječi pravilno, može uzrokovati ožiljke. Ovaj pregled istražuje različite vrste ožiljaka od akni i načine za njihovo poboljšanje. Postoje tri glavne vrste: icepick, rolling, and boxcar scars , koje se razlikuju po dubini i izgledu. Dostupni su mnogi učinkoviti tretmani, uključujući lasers, radiofrequency, micro-needling, and chemical peels.
      Acne vulgaris is a chronic skin disease that, depending on its course, is characterized by the occurrence of various skin eruptions such as open and closed comedones, pustules, papules, and cysts. Incorrectly selected treatment or the presence of severe acne vulgaris can lead to the formation of atrophic scars. In this review, we summarize current knowledge on acne scars and methods for their improvement. There are three types of atrophic scars: icepick, rolling, and boxcar. They are of different depths and widths and have different cross-sections. Scars can combine to form clusters. If acne scars are located on the face, they can reduce the patient's quality of life, leading to isolation and depression. There are multiple effective modalities to treat acne scars. Ablative lasers, radiofrequency, micro-needling, and pilings with trichloroacetic acid have very good treatment results.
