Too greasy but love the beneficial ingredients
I bought this product for the benefits of all the beneficial ingredients so I really hope over time it will work. The main problem I have with this product....it is so greasy even after applying just a little bit. There is no way to use it in the morning because I wouldn't be able to apply my makeup over it. At night I can feel my pillow case sticking to my eyes. Even though I believe in all the beneficial ingredients I dont think I will buy this again.

Response from COSMEDIX
Hi Christine! Opti Crystal is super powerful and hydrating, so you only need a tiny pin-sized drop for both eyes! It should soak in nicely if you use a smaller amount. We also recommend trying Eye Genius for the daytime, as it has light-reflecting pigments that look great under makeup. We hope you see the results you're looking for! Thank you so much for being a COSMEDIX customer! - The COSMEDIX Team

Super moisturizing
I really love this eye serum! I like that it is on the heavier side, however I see why they say a little goes a long way. It can be a little greasy if you use too much.

Great for puffiness
I used to believe eye creams were moisturizer in a smaller package, I was totally wrong. This serum has changed my mind, it absorbs quickly without leaving any residuo but keeps my under eye moisturized and the puffiness that I had since long time ago are gone. I highly recommend it
