Herbal Anti-Aging Creams: Pathophysiology, Molecular Mechanisms, Formulation, And Testing: A Comprehensive Review

Skin aging is a complex biological process driven by intrinsic factors such as cellular senescence and genetic regulation, along with extrinsic influences including ultraviolet radiation, oxidative stress, and environmental pollutants. These factors collectively contribute to molecular and structural changes in the skin, including excessive reactive oxygen species generation, activation of inflammatory mediators, degradation of extracellular matrix proteins, and impairment of dermal signaling pathways. Growing safety concerns associated with long-term use of synthetic anti-aging agents have increased interest in herbal-based topical formulations.This review provides a comprehensive overview of the pathophysiology of skin aging with particular emphasis on underlying molecular mechanisms relevant to pharmacological intervention.Furthermore, formulation approaches for herbal anti-aging creams are outlined, including extract standardization, excipient selection, and strategies to enhance skin permeation and formulation stability. Common evaluation and testing methods, including physicochemical characterization, in vitro antioxidant and anti-inflammatory assays, ex vivo skin penetration studies, and safety assessments, are also summarized. Overall, the review highlights the pharmacological relevance of herbal anti-aging creams and supports their potential as safe and effective topical therapies.
