A fast-acting algae serum for firmer, smoother, brighter skin
Biotherm Blue Therapy Accelerated Repairing Serum is a fast-acting anti-ageing serum for all skin types showing wrinkles, dark spots and loss of firmness. Its formula is concentrated in Alaria esculenta, the seaweed Biotherm calls the “Algae of Youth”, with Pro-Xylane, vitamin C glucoside and hyaluronic acid. Biotherm reports firmer, smoother, more even and radiant skin in four weeks, with wrinkles, dark spots and sagging looking reduced.
The texture
A fresh gel with soft pearly reflects that blends in easily, leaves no sticky feel and gives an instant glow under make-up.
Who it suits
- All skin types, 35+
- Wrinkles, fine lines and dullness
- Early loss of firmness
Worth knowing before you buy: It contains denatured alcohol and fragrance, which very sensitive skin may not like.
