La Roche-Posay Hyalu B5 Hyaluronic Acid Serum is a lightweight yet powerful serum that penetrates deep beneath the layers of the skin to target dehydration and skin that shows the visible signs of ageing. Formulated especially for sensitive skin, the serum absorbs quickly into the layers of the skin, locking in essential moisture, whilst working deep beneath the pores to plump and replenish dull, tired-looking skin. The serum also targets signs of ageing by stimulating the natural production of collagen beneath the skin, helping to increase elasticity of the visage and leave the texture soft and bouncy to the touch. Unique to La Roche-Posay, the serum is fortified with thermal mineral waters found only in the French spa town of La Roche Posay in the Loire Valley – waters which are known for their healing and de-stressing properties. Two different molecules of hyaluronic acid ensure that both the surface of the skin and the layers beneath are targeted to improve texture and reduce the appearance of fine lines and wrinkles. Vitamin B5 and Madecassoside help stimulate the skins natural repairing process, soothing damaged and scarred skin. Use once a day on a cleansed face. Apply to the face and neck. Avoid the eye areas.
