      Acne vulgaris adalah kondisi kulit kronis yang menyebabkan berbagai jenis jerawat seperti komedo terbuka dan tertutup, pustula, papula, dan kista. Jika tidak ditangani dengan baik, dapat menimbulkan bekas luka atrofi. Ulasan ini mengeksplorasi berbagai jenis bekas jerawat dan cara memperbaikinya. Ada tiga tipe utama: bekas luka tipe icepick (icepick scar), rolling (rolling scar), dan boxcar (boxcar scar), yang kedalaman dan tampilannya bervariasi. Ada banyak perawatan efektif yang tersedia, termasuk laser, radiofrekuensi, mikro‑needling, dan peeling dengan asam trikloroasetat (TCA) (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.
