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 November 5, 2023* ### ⭐⭐⭐⭐⭐ Review *by A***L on March 27, 2018* ### ⭐ Review *by A***A on February 20, 2026* ## 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.vu/products/26721315-under-eye-serum-for-dark-circles-and-puffiness-opti-crystal](https://www.desertcart.vu/products/26721315-under-eye-serum-for-dark-circles-and-puffiness-opti-crystal) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
