Cosmedix optic eye crystal

Love this, being a flight attendant and being dehydrated and fighting age around the eye area, this is the best product I’ve tried. Highly recommended

Cosmedix eye serum

This serum is fantastic! It has definitely helped with fine lines around eye area. I use it at night only as it’s tacky (and colored) consistency stays on the skin for quite some time. Not a wear and go product but highly effective. Would definitely purchase again.

Opti Crystal Eye Serum

Eyes feel hydrated with reduced bags and puffiness. A little goes a long way.
