How do they use Nanochemistry in mascara?

to apply mascara u get the brush and gently brush up against you eye lashes

It's basically to make your eyelashes stand out. Sometimes it can widen your eyes.And different mascaras do different things.Volumizers make your eyelashes fuller.lengthers make them longer.

covergirl lashblast is an ah-mazing mascara!!! it doesn't clump and it makes your lashes look super thick.

Clear mascara can be used just like regular mascara. But it doesn't run black streaks down your cheeks and washes out easily. It's also good for shaping your eyebrows.
