Abstract

Atrophic acne scars, the most common sequel of acne vulgaris are always a challenge to treat. Though many new modalities including chemical peels, soft tissue augmentation, lasers (non-ablative, ablative and fractional), subcision and radio frequency have been used. Microneedling stands out to be the cheapest, easiest and most efficacious modality in Indian skin type. We evaluated its effectiveness as the sole modality for treating atrophic acne scars. We found that there was an overall improvement in 91.8% patients by at least one grade. There were no serious complications except transient pain, erythema and oedema for 3-6 hours.

萎縮性痤瘡疤痕是尋常痤瘡治療上最常見的後續挑戰。雖然現今一眾新式療法如化學換膚、軟組織增大、激光如非剝離性、剝離性和分段式、皮下分離和射頻等都有效用,但微針在印度皮膚類型中因其最便宜、最簡單及高成效而排眾而出。我們評估其作為萎縮性痤瘡疤痕的單一治療方法的有效性。我們發現91.8%的患者至少有一個級別的總體改善。除了為時三至六小時的短暫疼痛、紅斑和水腫,沒有嚴重併發症發生。
