Guinot: Hydra Summum Serum

Apply morning and/or evening to the face after cleansing thoroughly, as a treatment course before the moisturizer.

Key active ingredients:

Hydralogic Complex (high concentration in Hyaluronic Acid and Aquasinol):

• Forms an anti-evaporation barrier: reinforces the structure of the skin barrier to limit moisture loss and reach an optimal level of moisturization.
• Retains moisture in the skin: helps recover the capabilities of young skin to retain moisture by stimulating the synthesis of "water reservoir" molecules.
• Infuses skin with moisture: stimulates hydration and improves moisture diffusion throughout the skin by stimulating the synthesis of Aquaporins. These proteins form an intercellular channel to facilitate moisture flow.
