      Acne vulgaris ni hali ya ngozi ya muda mrefu na husababisha aina mbalimbali za chunusi kama vile weusi na uvimbe. Ikiwa haijatibiwa vizuri, inaweza kusababisha makovu. Tathmini hii inachunguza aina tofauti za makovu ya chunusi na njia za kuyapunguza. Kuna aina tatu kuu: icepick, rolling, na boxcar scars, ambazo hutofautiana kwa kina na muonekano. Kuna matibabu mengi madhubuti yanayopatikana, ikijumuisha lasers, radiofrequency, micro‑needling, na 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.
       A systematic review and meta-analysis on the effects of the ultra-pulse CO2 fractional laser in the treatment of depressed acne scars 35249351
      Utafiti huu ulichunguza karatasi sita kuhusu jinsi laser ya CO2 Ultra‑pulse inavyoshughulikia makovu ya chununi yaliyopungua. Matokeo yalionyesha kuwa matibabu haya ya laser yalikuwa na ufanisi zaidi ikilinganishwa na njia zingine, na kusababisha matokeo bora katika viwango vya uboreshaji na jinsi ngozi ya wagonjwa ilivyobadilika.
      This study examined 6 papers about how well the ultra-pulse CO2 fractional laser treats depressed acne scars. The results showed that this laser treatment was more effective compared to other methods, leading to better outcomes in terms of improvement rates and how smooth patients' skin felt.
