Abstract
Background: Acne vulgaris is a prevalent chronic inflammatory skin condition that affects individuals across all age groups, with significant psychological and social impacts. Acne scarring, a common consequence of the disease, can lead to permanent physical disfigurement and emotional distress. Various treatment options, including microneedling, chemical peels, and laser therapies, have been proposed to improve acne scars. However, the comparative effectiveness of these therapies remains a topic of ongoing research and debate (Tan & Bhate, 2015; Bickers et al., 2006).
Objectives: This review aims to systematically evaluate the clinical and long-term outcomes of microneedling, chemical peels, and laser therapy for acne scarring. By analyzing existing literature, we seek to determine the most effective treatment modality based on various clinical metrics and patient outcomes.
Methodology
A comprehensive meta-analysis was conducted, focusing on studies comparing microneedling, chemical peels, and laser therapy for acne scarring. Relevant articles were sourced from databases such as PubMed, Scopus, and Google Scholar. Only randomized controlled trials (RCTs), cohort studies, and comparative studies published in peer-reviewed journals were included. Data on treatment efficacy, side effects, and long-term outcomes were extracted and analyzed (Fabbrocini et al., 2010; Gozali & Zhou, 2015).
Results
The results suggest that microneedling demonstrates superior efficacy in improving acne scars, particularly for atrophic scars, when compared to chemical peels and laser treatments. Chemical peels were found to be effective in reducing post-inflammatory hyperpigmentation but showed limited improvement in deeper scars. Laser therapies, while effective for both atrophic and hypertrophic scars, exhibited higher complication rates and longer recovery times (Connolly et al., 2017; Saadawi et al., 2019). Long-term follow-up data indicated that microneedling maintains scar improvement for up to 12 months, while chemical peels and laser therapies required more frequent maintenance treatments.
Conclusion
Microneedling appears to be the most effective and minimally invasive treatment for acne scarring, providing lasting results with fewer complications. While chemical peels offer benefits for superficial scars and pigmentation, laser treatments may be more appropriate for severe cases, despite higher risks and recovery times. Future studies with larger sample sizes and long-term follow-ups are needed to further solidify these findings (Ibrahim et al., 2017; Singh & Yadav, 2016).
