Product summary

Based on the ingredients included, "Stratia - Interface" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Stratia - Interface ticks this box. Humectants in this product (copper palmitoyl heptapeptide-14, heptapeptide-15 palmitate, panthenol, glycerin and sodium hyaluronate) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (rosa rubiginosa seed oil, dimethicone, squalane, cetearyl alcohol and c13-14 isoparaffin) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

  • This product contains acids (lactic acid 0.30% - 0.55% and glycolic acid 0.30% - 0.60%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
  • We like that this moisturizer contains peptides (heptapeptide-15 palmitate 0.45% - 0.70% and copper palmitoyl heptapeptide-14 0.50% - 0.70%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
  • Panthenol (pro-vitamin B5) at about 2.30% - 2.90% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: vitamin e and lactic acid
