THE COSMEDIX DIFFERENCE
Powerful Results, Visible Transformation.
Opti Crystal Liquid Crystal Eye Serum
Opti Crystal is our #1 bestselling Liquid Crystal Eye Serum with Spin Trap that deeply hydrates dry skin with Liquid Crystals to help drastically reduce the appearance of undereye dark circles, fine lines, and crow's feet.
7ml/ .25oz
Opti Crystal is COSMEDIX’s bestselling Liquid Crystal Eye Serum, expertly formulated to hydrate, illuminate, and visibly rejuvenate the delicate eye area. Designed for all skin types and tones, this lightweight yet powerful serum targets the most common signs of eye fatigue—dark circles, fine lines, dehydration, and loss of radiance—without irritation or heaviness.
At the core of Opti Crystal is COSMEDIX’s proprietary Liquid Crystal Technology, a biomimetic delivery system inspired by the skin’s own lipid structure. This advanced system allows hydration and active ingredients to absorb more efficiently, supporting optimal moisture balance while maintaining skin comfort and tolerance—an essential consideration for the fragile eye contour.
Opti Crystal features Spin Trap, an innovative antioxidant complex that neutralizes free radicals before they can damage the skin. By addressing oxidative stress caused by environmental aggressors such as pollution and blue light exposure, Spin Trap helps protect the eye area from premature aging while promoting a brighter, smoother appearance over time.
Hydration is central to the performance of Opti Crystal. The formula replenishes moisture levels to visibly plump fine lines and soften crepey texture, creating a smoother surface that reflects light more evenly for an instant brightening effect. Unlike heavier eye creams that can migrate or sit on the surface, Opti Crystal absorbs quickly and layers seamlessly under makeup, making it ideal for both morning and evening routines.
Beyond hydration, Opti Crystal works to visibly improve the appearance of dark circles and puffiness. Carefully selected brightening and skin-conditioning ingredients help support microcirculation and reduce the look of discoloration, while calming agents help minimize the appearance of under-eye fatigue. The result is an eye area that looks more rested, refreshed, and luminous—even on minimal sleep days.
COSMEDIX formulates with a skin health–first philosophy, and Opti Crystal reflects that commitment through its gentle yet results-driven approach. Free from unnecessary irritants and designed for daily use, this serum delivers visible correction without compromising skin tolerance, making it suitable for sensitive skin and post-treatment routines alike.
Opti Crystal is also designed to complement professional treatments and at-home regimens seamlessly. Whether used alone for daily hydration or layered with other targeted treatments, it supports long-term eye health while delivering immediate cosmetic benefits. Its versatile texture and clinical performance make it a favorite among estheticians and skincare professionals worldwide.
With consistent use, Opti Crystal helps transform the eye area into a smoother, brighter, and more resilient zone—one that reflects COSMEDIX’s commitment to clean, clinical, and luxurious skincare without compromise.

This eye serum delivers deep hydration and brightening with a unique iridescent texture. Customers said it "reduces dark circles," "diminishes fine lines," and "makes eyes look more awake." Most love the rich, balm-like consistency, though some find it too thick or sticky for daytime use. A tiny amount goes far, making it last despite the small tube size.
- It moisturizes, decreases puffiness, & diminishes crow's feet around my eyes. It really is magic.
- Absolute best eye serum i have ever bought. Will definitely buy again and recommend to friends.
- Brightens under my eyes and I barely have any wrinkles. I just turned 55

I have been using this for the past five years, and a tiny drop goes a very long way and does miracles for around your eye. I’m 65 years old and don’t have a crease or just coloration under and around my eyes.

I've been using this eye serum for 15+ years, and I believe it's made a difference in the aging of the skin around my eyes. At 50, I don't have static wrinkles. I haven't found anything else to be as hydrating.

I’ve used many under eye serums before; however, nothing beats the results I have received from using Opti Crystal. I’m extremely pleased with the results. In addition, the price point is reasonable for the results achieved.

Found this product quite by accident! Decided to try something new as my usual under eye moisturizer was not working well for me anymore. My salon carried the Cosmedix line and my stylist recommended Opti Crystal, her favorite! Was more pricey than what I usually pay, but gave it a try anyway. Glad I did! I have been using this product FOR YEARS!

Love this! I used Eye doctor years ago and enjoyed it but then recently my esthetician suggested Opti Crystal and it works wonders! I will say I don’t see much difference not wearing it but it corrects and it great when I apply!
