Science
Mechanism of Action
Hippophae Rhamnoides Water, a botanical distillate, delivers trace amounts of beneficial compounds such as vitamins (e.g., C), flavonoids, and carotenoids. These components act as mild antioxidants, neutralizing free radicals and offering protection against environmental stressors. It also provides light hydration, aiding in skin moisture retention and contributing to overall skin conditioning. Furthermore, it serves as an excellent solvent, facilitating the even distribution of other active ingredients and improving formulation texture.

Key findings
- 01 An oil-in-water emulsion formulated with 5% Hippophae rhamnoides extract demonstrated extremely significant improvements in skin hydration (p=0.0003) and reduction in transepidermal water loss (TEWL) (p=0.0087) over an 84-day period compared to a placebo, indicating benefits for skin barrier function. While this study utilized a concentrated extract, Hippophae Rhamnoides Water provides a gentle source of similar beneficial compounds.
- 02 A water-soluble sea buckthorn extract is commonly incorporated into cosmetic formulations at concentrations ranging from 0.5% to 5% to enhance their properties.
