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. Review: 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. ## Features - Ultra-Hydrating Eye Serum: Opti Crystal Eye Serum is a luxurious Liquid Crystal serum specially formulated with powerhouse ingredients to reduce the look of dark circles and improve the look of fine lines, wrinkles and sagging around the eyes. - For a Rested, Youthful Appearance: Infused with soothing coconut and liquid crystal technology to deliver unprecedented hydration to the delicate eye area.

The article also included a link to the COSMEDIX's own website as well (price was $104 there). I don't believe that InStyle magazine would be publishing links on their website to Amazon sellers that were selling counterfeit (read ILLEGAL & DANGEROUS) products. Also I'm quite sure whenever those type of review/promotional articles are written about products on these websites - the companies are very much aware of the article being published and any links to their products in said articles. So I wouldn't worry about the legitimacy of this particular product. Hope this helps!! **Q: How many applications are in the tube** A: I use this product at bedtime and 1 tube lasts about 4 months. It only takes a very small amount (less than the size of sesame seed) to get excellent results. ## Customer Reviews ### ⭐⭐⭐⭐⭐ really good! *by み***や on November 5, 2023* This product is really good if you ask me.

Sticky like honey. *by A***A on February 20, 2026* This is not a serum. This is a Vaseline times million substance that is sticky to the point where dust was sticking into it. It looked like if you would put honey under eyes. And I had horrible eye allergy reaction to this. Do not recommend. ## Frequently Bought Together - COSMEDIX Under Eye Serum for Dark Circles & Puffiness, Opti Crystal - Lifting & Firming Liquid Serum for Fine Lines & Wrinkles - Brightening, Moisturizing, & Hydrating Anti Aging Eye Puffy Bags Serum - COSMEDIX Hydrating Face Wash for Women & Men, Benefit Clean Gentle Cleanser Gel - Moisturizing Face Cleanser & Pore Minimizer For All Skin Types - Facial Cleanser Makeup Remover for Glowing Skin - COSMEDIX Harmonize Microbiome Boosting Moisturizer - Ultra-Light Prebiotic Facial Skin Care Products for Softer, Smoother & Vibrant-Looking Skin - Face Lotion for All Skin Types --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/26721315-under-eye-serum-for-dark-circles-and-puffiness-opti-crystal](https://www.desertcart.com.kw/products/26721315-under-eye-serum-for-dark-circles-and-puffiness-opti-crystal) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-20*
