All studies were clinical trials, most of them recruited women only and 67% had an intra‐patient study design. About half of the active cosmetic creams tested only contained one active ingredient among xanthenes, herbals or retinoids. The other studies tested cosmetic creams with more complex formulations and most of them included xanthenes. A total of seven controlled trials satisfied the inclusion criteria for the meta‐analysis. The pooled mean difference of thigh circumference reduction between the treated and the controlled group was −0.46 cm (95% confidence intervals, CI: −0.85, −0.08), with significant heterogeneity between studies (<italic>P</italic> < 0.001).</p> </sec> <sec id="jdv12193-sec-0005" sec-type="section"> <title>Conclusion</title> <p>This article provides a systematic evaluation of the scientific evidence of the efficacy of cosmetic products in cellulite reduction and supports a moderate efficacy in thigh circumference reduction.</p> </sec> </abstract>
