Chemical Peels as Field Therapy for Actinic Keratoses: A Systematic Review

BACKGROUND Actinic keratoses (AKs) are a common premalignant cutaneous neoplasm and can progress to squamous cell carcinoma. A variety of treatment options are available for field therapy of diffuse AKs. OBJECTIVE This review systematically analyzes the use of chemical peels for treatment of AKs. MATERIALS AND METHODS A systematic review of PubMed was performed searching from 1946 to March 2020 to identify the literature on chemical peels for AKs. RESULTS Of the 151 articles identified, 5 met inclusion criteria for review. Four of the reviewed articles demonstrated the efficacy of chemical peels in reducing AK count and minimal adverse effects. In some studies, chemical peels exhibited potential to prevent additional AK formation and development of keratinocyte carcinomas. CONCLUSION Chemical peels are an efficacious and affordable treatment option for field treatment of AKs. With improved patient tolerance and adherence, chemical peels are an attractive option for field therapy of AKs for both dermatologists and patients.
