Intensive, immediate and sustainable hydration for dehydrated skins

Yon-Ka researchers have created an exclusive hydrating complex that can be found in the HYDRA N°1 serum, cream and fluid, and that allows to act upon the hydration of the skin at all levels.

  • Olive phytosqualanes and aloe vera strengthen the skin’s barrier.
  • Imperata cylindrica regulates the water transfers from the epidermis to the dermis, 2 types of hyaluronic acid (high and low molecular weight) help the skin maintain its water capital.
  • Antioxidant vitamins A, C and E protect the molecules that retain water.

A well hydrated skin is supple, soft and comfortable, and also plumped and glowing. The hydration of the skin is the 1st anti-aging step, no matter what your skin type may be. Since combinations or oily skins may also show signs of dehydration, in addition to a cream for dry skins, we have complemented our hydration program with a specific hydrating fluid designed for skins prone to oiliness and/or for women who prefer a lighter texture.
