Hyaluret Serum S13

  • Hyaluret Serum S13 contains a revolutionary ester of retinoic and hyaluronic acid (sodium retinoyl hyaluronate). Stronger than retinol, this hero anti-aging ingredient combines two molecules into one and doesn't require a prescription. Quick-absorbing and oil-free, Hyaluret serum delivers actives that have been shown to increase the production of collagen, improve skin elasticity and fight acne.
  • During in-vivo testing, subjects applied sodium retinoyl hyaluronate to half the face and a placebo to the other half. In a six-week study, 14 subjects demonstrated a 36% reduction in wrinkles, 34% increased skin elasticity, and 43% improvement in skin roughness on the portion of the face where sodium retinoyl hyaluronate was applied.
  • In a separate study, in which the same procedure was followed, 16 volunteers with problem skin reported a visual improvement of acne and showed 43% reduction in sebum content, and 25% reduction of pore size.
  • The low molecular weight of retinoic and hyaluronic acid ester (10-20KDa) allows it to penetrate skin more deeply than retinol to deliver its plumping, hydrating and anti-ageing benefits without inducing irritation. Sodium retinoyl hyaluronate has been shown to stimulate collagen and fibronectin production while fighting the causes of acne.
  • Hyaluret is entirely oil-free and is formulated with complimentary botanical extracts to calm blemishes and hydrate skin. Liquorice works to calm stressed skin and balance oily or congested complexions while dill helps to enhance skin’s resilience.
  • Beta-Glucan helps defend skin from daily environmental damage as its molecules link together on skin’s surface to lock in hydration and enhance barrier defence.
  • Free from parabens, silicones, PEGs, SLS, SLES and mineral oils. Vegan and free from animal testing. Made in the UK.
