You may not have heard of the brand SENTÉ yet, but you will. This exciting skincare line has a unique new ingredient: Heparan Sulfate (HSA). “In the body, HSA is involved in signaling pathways between cells—regulating growth factors, collagen adhesion, neovascularization or new blood vessels, and even anticoagulation among many biochemical processes,” says David Shafer, MD, a NYC-based plastic surgeon. “When applied topically, HSA boosts rejuvenation and skin hydration likely through its effect on collagen, growth factors, and blood flow.” The results of SENTÉ’s HSA-formulated serums are firmer and smoother skin, improved strength and elasticity, and the fading of fine lines.
