Review: 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. Review: UPDATE- I spoke to Cosmedix and they confirmed that it is legit product, plus desertcart replaced the one that arrived leaking. At this price the Opti Crystal is a bargain price. You only use a pinprick amount so it lasts for months and is a highly effective eye product. My review has now changed to 5 stars. Original review: I’ve purchased this product previously from a different retailer and know it’s great. But this Opti Crystal arrived with neither the tube or box protected with any kind of seal. The product has also leaked into the lid. It feels like someone has previously opened and tried it before returning. Either way it feels unhygienic. I’m returning and requested a replacement. I’m also going to check with Cosmedix on how it should be packaged. (Opti Crystal I’d usually around £90, so if legit this is a bargain price, or it could be too good to be true. I’ll update when I find out more from Cosmedix.) ## Features - Helps hydrates the under eye area and plump the look of fine lines - Protect under eye area from environmental stressors, which can accelerate signs of aging - Drastically reduce the appearance of dark circles and crow’s feet ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01CPSP7PM | | ASIN | B01CPSP7PM | | Best Sellers Rank | #61,587 in Beauty ( See Top 100 in Beauty ) #167 in Eye Serums & Fluids | | Brand Name | CosMedix | | Customer Reviews | 4.2 4.2 out of 5 stars (202) | | Customer reviews | 4.2 4.2 out of 5 stars (202) | | Date First Available | 8 April 2016 | | Department | Unisex-Adult | | Global Trade Identification Number | 00847137052652 | | Included Components | 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 | | Is Discontinued By Manufacturer | No | | Item Form | Creams, Gels and Lotions | | Item Type Name | 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 | | Item Volume | 0.05 Fluid Ounces | | Item Weight | 0.2 Ounces | | Item model number | 931402010 | | Manufacturer | COSMEDIX | | Manufacturer | COSMEDIX | | Manufacturer Part Number | 8770310 | | Material Features | Antioxidant | | Material Type Free | Gluten Free | | Model Number | 931402010 | | Number of Items | 1 | | Product Benefits | Encourages the appearance of firmer skin, helps fight harmful free radicals, and provides deep, lasting hydration. | | Product Dimensions | 9.68 x 2.54 x 1.12 cm; 5.67 g | | Recommended Uses For Product | dermatology | | Scent Name | Coconut | | Skin Tone | All | | Skin Type | Normal | | Special Ingredients | Antioxidants | | Target Use Body Part | Face | | UPC | 847137020200 847137052652 | | Unit Count | 7 Grams | ## Product Details - **Scent:** Coconut - **Skin type:** Normal - **Special ingredients:** Antioxidants - **Use for:** Face ## Images ![931402010 Opti Crystal Liquid Crystal Eye Serum 7 g - Image 1](https://m.media-amazon.com/images/I/71UeE1pjmRL.jpg) ## Questions & Answers **Q: Do you put a concealer on top?** A: Yes, the optic crystal serum serves as a wonderful base to keep the concealer from looking dry and increasing the look of fine lines. **Q: How many times a day should i use it (am & pm)?** A: Once a day or even ever other day….. **Q: Is this real? why is it half the cost of the same product on the manufacturer's website?** A: I was directed COSMEDIX's Amazon store to purchase the Opti Liquid Crystal Eye Serum ($95) by using a link in an article I read about it on the InStyle magazine website. 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 ### ⭐⭐⭐⭐⭐ Review *by み***や on 5 November 2023* This product is really good if you ask me.

Other reviews are true - you only need a tiny bit and it is quite sticky. I dot it under my eyes and leave for a minute while I do something else, give it a moment for body heat to kick in. Then dot it around the area - no dragging necessary if it’s warmed up a little. I don’t use skin coverage so I can’t comment how foundation or eye cream sits. I’m naughty and use twice a day and have to hold myself back from using more than I need. Tube last 4 months. RRP is around $180 but if you shop around, can get for $106-$115 to $140. Record was $98. This is a must have and I dread eventual retirement when I’ll have to face up to if I can afford it or not! I’ve tried other eye serums/creams which have done nothing but smell nice and be a bit moisturising. ## 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/271252814-931402010-opti-crystal-liquid-crystal-eye-serum-7-g](https://www.desertcart.com.kw/products/271252814-931402010-opti-crystal-liquid-crystal-eye-serum-7-g) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-19*
