Effectiveness was not significantly different: trichloroacetic acid versus salicylic acid (SA) (percentage of total improvement: risk ratio (RR) 0.89; 95% CI 0.73 to 1.10), glycolic acid (GA) versus amino fruit acid (the reduction of inflammatory lesions: mean difference (MD), 0.20; 95%\u2009CI \u22123.03 to 3.43), SA versus pyruvic acid (excellent or good improvement: RR 1.11; 95%\u2009CI 0.73 to 1.69), GA versus SA (good or fair improvement: RR 1.00; 95%\u2009CI 0.85 to 1.18), GA versus Jessner\u2019s solution (JS) (self-reported improvements: RR 1.00; 95%\u2009CI 0.44 to 2.26), and lipohydroxy acid versus SA (reduction of non-inflammatory lesions: 55.6%vs48.5%, p=0.878). Combined SA and mandelic acid peeling was superior to GA peeling (percentage of improvement in total acne score: 85.3%vs68.5%, p&lt;0.001). GA peeling was superior to placebo (excellent or good improvement: RR 2.30; 95%\u2009CI 1.40 to 3.77). SA peeling may be superior to JS peeling for comedones (reduction of comedones: 53.4%vs26.3%, p=0.001) but less effective than phototherapy for pustules (number of pustules: MD \u22127.00; 95%\u2009CI \u221210.84 to \u22123.16).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Limitations<\/jats:title>\n                  <jats:p>The methodological quality of the included RCTs was very low to moderate.
