From the manufacturer:

Give your skin the illusion of perfection with this fast-acting pre-makeup treatment whose age-minimizing action helps produce smooth, radiant, line-free skin with a beautiful rosy glow. 

Based on advanced marine collagen technology it gently “plumps” the surface of the skin to fill in fine lines and minimize wrinkles. At the same time, light-deflecting polymers and optical diffusers camouflage flaws and even the skin tone.
