INTRODUCTION & OBJECTIVES

Today, state-of-the-art sunscreen formulas can efficiently filter UV wavelengths up to 370/380 nm but have limited absorption in the 370/380–400 nm range of wavelengths. Recently, a new cyclic merocyanine UVA1 absorber, Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate (MCE), exhibiting a maximal peak of absorption at 385 nm was approved by the Scientific Committee on Consumer Safety (SCSS) for use in sunscreen products. This study was to evaluate in vivo global anti-aging benefits of a higher and broader UVA1 protection with the daily application of a sunscreen formulation enriched with MCE in Brazilian and Chinese populations.
