Topical Management of Cellulite (Edematous-Fibro-Sclerotic Panniculopathy, EFSP): Current Insights and Emerging Approaches

Cellulite, or edematous-fibro-sclerotic panniculopathy (EFSP), is a multifactorial condition affecting most postpubertal women, characterized by surface irregularities with significant psychosocial impact. Its pathogenesis involves adipocyte metabolism, fibrous septa, microvascular dysfunction, extracellular matrix (ECM) remodeling, oxidative stress, and low-grade inflammation. Topical therapies remain among the most accessible approaches, acting on specific biological pathways. Osmotic and vSSasomodulatory formulations reduce edema and improve microcirculation, while methylxanthines such as caffeine and aminophylline promote lipolysis and enhance cutaneous blood flow. Retinoids mainly target the ECM, stimulating neocollagenesis and dermal thickening, with greater efficacy in early EFSP. Botanicals, including Centella asiatica, Rosmarinus officinalis, and Ginkgo biloba, provide antioxidant, anti-inflammatory, and venotonic effects. Randomized controlled trials consistently report modest but reproducible benefits: localized circumference reductions and improved elasticity, echogenicity, and orange-peel scores, all with excellent tolerability. Recent innovations, such as lipid nanoparticles, ultradeformable vesicles, and microneedle-assisted delivery, aim to enhance penetration, stability, and sustained bioactivity of established actives. Nonetheless, most studies are small, short-term, and heterogeneous, with limited ability to isolate the role of individual components or control for massage-related effects. Artificial intelligence offers opportunities to standardize outcome measures, optimize formulations, and personalize protocols. Overall, topical therapies are best positioned as safe, biologically active adjuncts within multimodal cellulite management.
