Acne vulgaris は、黒ずみや嚢胞などのさまざまな種類のニキビを引き起こす長期的な皮膚疾患です。適切に治療しないと傷跡が残る可能性があります。このレビューでは、さまざまな種類のニキビ跡とその改善方法を検討します。主要なタイプは icepick, rolling, and boxcar scars の 3 つで、深さと外観が異なります。 lasers, radiofrequency, micro-needling, and chemical peels をはじめ、多くの効果的な治療法が利用可能です。
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.

この研究では、ウルトラパルス CO2 フラクショナル レーザーが陥没ニキビ跡をどの程度治療するかについて 6 つの論文を調査しました。その結果、このレーザー治療は他の方法と比較してより効果的であり、改善率と患者の肌の滑らかさの点でより良い結果につながることがわかりました。
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.
