Mae Acne vulgaris yn gyflwr croen hirdymor sy'n achosi gwahanol fathau o pimples fel pennau duon a systiau. Os na chaiff ei drin yn iawn, gall achosi creithiau. Mae'r adolygiad hwn yn archwilio gwahanol fathau o greithiau acne a ffyrdd i'w gwella. Mae tri phrif fath: icepick, rolling, boxcar scars , sy'n amrywio o ran dyfnder ac ymddangosiad. Mae llawer o driniaethau effeithiol ar gael, gan gynnwys lasers, radiofrequency, micro-needling, 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.

Archwiliodd yr astudiaeth hon 6 phapur ynghylch pa mor dda y mae'r laser ffracsiynol CO2 ultra-pwls yn trin creithiau acne isel. Dangosodd y canlyniadau fod y driniaeth laser hon yn fwy effeithiol o gymharu â dulliau eraill, gan arwain at ganlyniadau gwell o ran cyfraddau gwella a pha mor llyfn y teimlai croen cleifion.
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.
