really good!
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.

Five Stars and it's WELL WORTH the money
I had this sitting in my cart for at least 4 months before I purchased it. The price tag had me a little apprehensive, but I finally ran out of my old stuff and thought I'd give this a try. It DOES NOT disappoint! First of all, you use such a tiny amount each night that I'm thinking this tube will last me at least 6 months. The quality is absolutely amazing... I can't say enough nice things about it. It goes on as this gorgeous pearl type color and immediately hydrates your under eyes. It's helped my dark bags look a little less prominent and it also has helped with the appearance of my crows feet. I would recommend everyone gives this a try! I'm actually going to look at their other skin care products to see if they have a full face cream I loved this THAT much.

Magic
There is a learning curve to applying this eye serum but just to say, less is more. You don’t need much. I let it sit for a few minutes and then continue to tap it in. It is sticky but eventually sinks in. I’m an esthetician and have tried soooo many eye products and this one has impressed me the most as far as how quickly you see results. I’m 53 and when I wear eye makeup it sometimes settles into the inner corner wrinkles that are normal for my age. This eye serum has solved that issue. I look in the mirror stunned. I also think it helps prolong my eye makeup during the day and simply firms the delicate skin around the eyes. For now I’m only using this product during the day and another eye cream at night. This product is pricey but with how small of an amount you need, this will last you a good while. I will be recommending this to clients.

Worth it!
I am a huge fan of this under eye cream. I purchased it to address dark circles, and I have definitely seen an improved difference in the hydration and color under my eyes.. Easy to apply, just a small dab is enough for under both eyes. It is a thicker than other under eye creams, almost gel like, but it does not feel heavy at all. It gets completely absorbed into the skin. And there is no funky smell. It seems a little expensive, but the small tube lasts quite a long time and is definitely an effective product. I definitely recommend this Cosmedix under eye brightening cream.

Good product poor packaging
I love this eye serum, but after less than a month of use the packaging cracked and most of the serum has leaked out. You would think for $100 eye serum Cosmedix would spend more on packaging. Because of high cost and loss of so much product from poor packaging will not buy again.

That’s a big No!
I was intrigued by this product when I saw it. I’ve taken really good care of my skin, no matter what I do eyes age different. For reference I do have eyelash extensions and that’s a BIG reason this is a big no! After applying no matter how little it turns into a sticky fly trap. I couldn’t tolerate the sticky consistency and my lashes sticking to my lids if reformulated to a silky smooth non sticky substance then I may try again! Also makeup doesn’t mesh with this in the least.

Works Like a Dream!
This is another product I first read about in The Cut. I had heard about Cosmedix before but reading about this particular product made me bite the bullet and boy, am I glad I did. It works like a dream. Within 5 days, I could tell a difference. It not only helps with my fine lines, but also dark circles and puffiness. It doesn’t have any kind of smell, which I like and it has a pearl-like iradeacent color so when you dab it in it becomes almost like a highlighter. I took what was left over on my finger and dabbed it into the other fine lines (smile & forehead) and they’re looking better, too. The one downside is it’s very sticky when it dries, but once you put on some moisturizer, that takes care of it. Long story short, this product is so worth it if you want something that works lie a dream!
