A pressed serum, which is Senté's term for a formula with the density of a cream and the delivery of a serum.

HydraFirm adds two further analog molecules to the patented Heparan Sulfate Analog: Dermatan Sulfate Analog and Chondroitin Sulfate Analog, which Senté positions as its skin-firming pair. Niacinamide and peptides sit alongside them. Senté reports visible change from four weeks with continued improvement through twelve, and 79 percent of subjects showing improvement in skin firmness at twelve weeks.

Best for loss of firmness and volume on skin that is also sensitive. Ideal pressed into the skin rather than rubbed in, morning and evening.

• Three analog molecules rather than one: heparan sulfate for repair, dermatan and chondroitin sulfate for firmness
• A pressed texture that sits between a serum and a cream, so more active is delivered per application
• Senté reports 79 percent of subjects showing improvement in skin firmness at twelve weeks

After cleansing, apply one to two pumps to the fingertips and press gently into the skin rather than rubbing it in. Allow it to absorb fully before the next step. Use morning and evening.

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

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.
