Extracted from Swiss glacial snow algae with unique stress response molecules, this powerful, moisturizing active improves skin structure and barrier function, promotes longevity, and evens skin tone for a protected, hydrated complexion.
How does it work?
STUDY #1: REDUCING THE EFFECTS OF AGING AT THE PROTEIN LEVEL
Primary human keratinocytes were cultured in this pro-aging medium with or without 0.0625% Snow Algae extract.
MRM proteomic analysis revealed changes in protein expression for the cells cultured in the pro-aging medium compared to the ones cultured in the classic medium. These changes are known to occur with age in vivo:
• down-regulation of proteins associated with protein synthesis, metabolism, DNA repair and electron transport • up-regulation of proteins associated with stress response, oxidized protein turnover and redox / antioxidant mechanisms • change in adhesion.
Snow Algae Powder was shown to reduce these age-related changes.
A hydrogel containing 2% Snow Algae Powder was applied twice daily for two months to the inner side of the forearm of five caucasian women aged between 55 and 67 (mean age = 60.6 years old) whilst their other forearm was treated with the corresponding placebo.
DEJ was analyzed using a two-photon microscope before and after treatment.
Results showed that Snow Algae Powder improved the undulations of the DEJ and increased its surface by 30.5% compared to the placebo. This indicates a rejuvenating effect of this connecting tissue.
STUDY #3: WATER LOSS REDUCTION
In a double-blind study performed with 21 Caucasian volunteers (19 women and 2 men) of phototype II and aged between 30 and 57 (mean age = 43.8 years old) during winter time, Snow Algae Powder was shown to reinforce the skin barrier by decreasing water loss.
TransEpidermal Water Loss (TEWL) was measured before and after treatment on the face (cheeks) using a tewameter.
Winter weather conditions led to an increased loss of water by the skin as shown with the placebo. However, Snow Algae Powder was shown to counteract this effect and to even reduce TEWL.
Therefore, Snow Algae Powder is able to reinforce the skin barrier even under challenging conditions.
