La Roche-Posay Hyalu B5 Suractivated Serum is an anti-aging serum suitable for all skin types, including sensitive and oily skin. Its formula was developed to address the main signs of aging, such as wrinkles, loss of firmness, volume, and elasticity. The formula is enhanced by a system of 4 forms of hyaluronic acid, with different molecular weights, which contribute to intense hydration and a plumping effect on the skin. Hyalu-Lock™ technology helps seal the hyaluronic acid into the skin, helping to prolong hydration. Vitamin B5 (panthenol) helps repair and strengthen the skin barrier, while hyaluronic acid helps retain moisture, improve plumping, and help correct the appearance of wrinkles. The formula also contains madecassoside, associated with the repairing and soothing action of the treatment. The serum-gel texture is light, fresh, and quickly absorbed, without a sticky feeling. The product is tested on all skin tones and types, including sensitive skin, and is non-comedogenic. The brand claims a plumping and repairing effect within 1 hour and visible wrinkle correction within 1 week, based on instrumental tests and clinical studies.
