The first step after cleansing, and the lightest formula in the Senté range.

Hydrate+ combines patented Heparan Sulfate Analog with the brand's Hydra4 Complex, which delivers hydration across more than the surface layer. It works on transepidermal water loss, the mechanism behind skin that feels tight soon after cleansing, and on barrier function rather than on surface moisture alone. Senté reports that 100 percent of subjects agreed it provides instant and long lasting hydration.

Best for dehydrated skin of any type, including oily skin that still feels tight. Ideal applied first, before anything heavier.

• Four forms of hyaluronic acid at different molecular weights, alongside the patented HSA
• Works on transepidermal water loss rather than on surface moisture alone, which is why the effect holds
• Senté reports 100 percent of subjects agreeing it provides instant and long lasting hydration

After cleansing, apply five to seven drops to the skin, morning and night. Allow the serum to absorb fully before applying anything heavier.

CAUTION: This product does not contain a sunscreen. Use a broad spectrum sunscreen during the day.

KEY INGREDIENTS
Heparan Sulfate Analog - Senté's patented repairing molecule, which boosts the skin's immune response to inflammation and promotes repair from within
Hydra4 Complex - Senté's own hydration system, which the brand positions as delivering hydration to more than the surface layer
Four forms of hyaluronic acid, with panthenol and sodium PCA - Humectants at different molecular weights, which is what allows hydration to sit at more than one depth

Senté was founded in 2007 on a molecule the body already makes. Heparan sulfate binds water and governs how skin responds to inflammation, and the supply falls as skin ages. Senté modified it into a topical-stable form, Heparan Sulfate Analog, and holds the patent, which is why it appears in no other line. The result is a range built for skin that is reactive rather than simply aging, and the brand's own clinical work reports visible change in weeks rather than months.
