Daily use of a bakuchiol and squalane-containing face serum impacts skin esthetics

Abstract

Objectives: The objective is to determine the impact of an oil-based face serum containing bakuchiol and squalane in improving skin esthetics such as texture and tone upon daily use. Material and Methods: A non-comparative, single-arm study on 50 females (aged 18–50 years) with Fitzpatrick skin types III and IV was conducted for four weeks. The impact of the formulation on skin-related parameters was determined by instrumental analysis and dermatologist evaluation. Cosmetic acceptability and safety of the preparation were recorded through self-evaluation questionnaires. Results: The formulation was safe and well tolerated throughout the study duration. A significant reduction in the appearance of age/dark spots (ITA°), Δ ITA° = 38.28% compared to baseline, was observed in two weeks. Up to 11.9% improvement in skin elasticity was noted in four weeks of usage. The continuous once-a-day application also helped in reducing the transepidermal water loss throughout the study. Conclusion: Regular use of facial oil serum can help improve skin texture and tone.
