La Roche-Posay Hyalu B5 Serum 30ml

Hyalu B5 Serum is La Roche-Posay's plumping and repairing serum for skin that is dehydrated, showing fine lines or recovering from treatments that dry it out. It combines two molecular weights of hyaluronic acid: a larger one that holds water at the surface for immediate smoothing, and a smaller fragmented one that penetrates further for deeper hydration and a longer-lasting plumping effect. Vitamin B5 (panthenol) supports repair and comfort, and madecassoside from Centella asiatica calms and supports the skin's own hyaluronic acid production. The texture is a lightweight gel-serum that absorbs fast and layers under any moisturiser or sunscreen, and it is tested on sensitive skin and safe alongside retinoids and acids.

Dehydrated skin makes every line look deeper and every anti-ageing active sting more. A hyaluronic serum plumps fine lines within minutes, keeps skin comfortable while stronger actives do their work, and, unlike many, this one also repairs, making it the serum to reach for after peels, retinoids or sun.
