The concept of beauty in Ayurveda is present as early as in *Caraka Samhitā* in the form of *varnya dashemani*.

However, many people have forgotten its anti-aging properties. Valuable components of *L. barbarum* are not limited to its colored components containing zeaxanthin and carotene but include polysaccharides and small molecules such as betaine, cerebroside, β-sitosterol, p-coumaric acid, and various vitamins. Despite the fact that L. barbarum has been used for centuries, its beneficial effects on our bodies have not been comprehensively studied using modern technology to unravel its therapeutic effects at the biochemical level. Recently, our laboratory has demonstrated its...

Research Summary: Background: Skin aging manifests in various forms such as wrinkles, uneven skin tone, and dryness. Both intrinsic and extrinsic factors, especially ultraviolet light-induced oxidative radicals, contribute to the etiology of aging. Human skin requires both water- and lipid-soluble nutrient components, including hydrophilic and lipophilic antioxidants. Vitamins C and E play important protective roles in the aging process and must be supplied exogenously. Raspberry leaf extracts contain botanical actives with the potential to hydrate and moisturize the skin. Topical products containing these ingredients may therefore provide enhanced anti-aging effects compared to single-ingredient formulations.Objectives: This study aimed to evaluate the...
