A featherlight serum with 1.5% hyaluronic acid for thirsty, tight-feeling skin
Uriage Eau Thermale H.A Booster Serum is a hydrating serum for all skin types, including sensitive skin, that shows signs of dehydration. It combines 1.5% hyaluronic acid in two molecular sizes with Aquaxyl, marshmallow flower extract and Uriage Thermal Water. Together they hydrate deeply, plump and smooth fine dehydration lines, and help protect the skin from external stress. Skin looks softer and more radiant.
The texture
An ultra-light, watery serum that melts into the skin in seconds and sits well under any moisturiser. It has a delicate fresh scent.
Who it suits
- Dehydrated skin that feels tight
- Fine lines caused by lack of water
- Dull skin that needs a glow
Worth knowing before you buy: The formula contains fragrance. It hydrates but does not nourish, so dry skin still needs a cream on top.
