Kumkumadi Taila improves facial skin pigmentation, erythema, and elasticity: an instrument-based exploratory proof-of-concept study with phytochemical profiling for primary skin care

Introduction: is a classical Ayurvedic facial oil traditionally used in primary care as a routine preventive skincare product to enhance the complexion; however, clinical instrument-based data and detailed chemical profiling remain scarce. Methods: device. Results: < 0.05), indicating that the data deviates from a normal distribution and is skewed. Overall, Melanin and Erythema Index decreased significantly, indicating improved pigmentation and reduced redness. Skin elasticity declined over time, while skin hydration fluctuated. TEWL and skin thickness remained stable throughout the study. Discussion: was associated with changes in selected facial skin biophysical parameters over 15 days. The study supports its potential as a safe and accessible primary care intervention in the form of a routine preventive skincare product, and its findings highlight the relevance of traditional Ayurvedic topical formulations in routine skin care. The study also demonstrates a practical framework for evaluating non-invasive skin metrics and phytochemicals, serving as a proof of concept.
