Ingredient callouts

  • this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.50% - 1.20%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • Adenosine 0.05% - 0.25%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • Panthenol (pro-vitamin B5) at about 0.35% - 0.85% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
  • Humectants (panthenol 0.35% - 0.85%, betaine 1.10% - 1.60% and glycerin 3.50% - 5.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
