COSMEDIX Opti Crystal Under Eye Serum for Dark Circles & Puffiness - Lifting, Firming & Anti-Aging Treatment for Fine Lines & Wrinkles - Brightening, Moisturizing & Hydrating Eye Cream - Perfect for Morning & Night Skincare Routine

This product is really good if you ask me. I bought it in march 2023, and I've been using it daily since then. The tube is TINY and it's not cheap but I've been using it for 9 months so value seems ok? I'm not even out of it yet but I'll reorder soon.I have basically no wrinkles under my eyes, and my skin is soft and moisturized there when I use it. I had some fine lines before but this product really works well.I see a lot of reviews talking about it being blue and shiny and the color not going away, as well as sticky, and not working with make up well. They may not be using it well because I have none of these problems.IMPORTANT: I use it in the morning before make up only. It will be sticky if you only use this.After washing my face, I mist with water and apply a vitamin C&E serum, followed by lightweight cica moisturizer all over. Once that dries, I squeeze 4-5 "flat dots" of COSMEDIX Opti Crystal Liquid Eye Serum under my eyes. I do this by squeezing a tiny bit and dabbing it directly onto my skin from the tube itself. I say "flat dots" because you need a small amount, not a blob of it. it's super important not to use too much.After that I pat it out all over under my eye with my ring finger. Once it's all spread out, if it's still quite blue, you have too much. at this point I see a shiny/sticky appearance, but not blue or aurora.Next, I apply matte BB cream and use the same patting out technique under my eye until desired coverage is achieved.BB cream is then followed by mineral foundation powder and by this point there is zero stickiness, my make up holds up well throughout the day with no creasing and maintaining a smooth appearance.I hope this helps.
