Acne vulgaris は、黒ずみや嚢胞などさまざまなタイプのニキビを引き起こす慢性皮膚疾患です。適切に治療しないと傷跡が残る恐れがあります。本稿では、ニキビ跡の種類とその改善方法について検討します。主なタイプは icepick、rolling、boxcar scars の 3 種類で、深さや外観が異なります。lasers、radiofrequency、micro‑needling、chemical peels など、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にどの程度効果があるかを、6 件の論文で検証しました。その結果、他の治療法と比較して本レーザー治療の方が効果的であり、改善率や肌の滑らかさにおいてより良い結果が得られることが示されました。
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.
