You feel the Complejo de 12 péptidos in Lash Boost Serum

I bought it for the Complejo de 12 péptidos and it delivered
I read the ingredient list before ordering and the Complejo de 12 péptidos was exactly what I wanted (with Hyaloveil™ alongside, even better). Three weeks with the Lash Boost Serum and my skin looks more even and comfortable.

Very good serum, needs a month
Lash Boost Serum works, but be patient. Four weeks in and my skin is more even and bright. Not overnight magic.
