Opti Crystal es nuestro sérum para ojos de cristal líquido número 1 en ventas con Spin Trap que hidrata profundamente la piel seca con cristales líquidos para ayudar a reducir drásticamente la apariencia de ojeras, líneas finas y patas de gallo.

7 ml / 0,25 oz
  • Helps minimize the appearance of fine lines and wrinkles
  • Brightens the look of dark circles under eyes
  • Deeply hydrates to encourage the appearance of firmer skin

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.

CLEAN & CLINICAL, BACKED BY SCIENCE

Botanical ingredients meet clinical-grade actives for proven results.

Customers praised this eye serum for its deep hydration and visible brightening effects. "It moisturizes, decreases puffiness, & diminishes crow's feet," one reviewer noted. Many appreciated the iridescent texture and that "a little goes a long way." However, some found the thick, sticky consistency challenging, with concerns about greasiness and makeup compatibility.

  • Moisturizes, decreases puffiness, & diminishes crow's feet around my eyes. It really is magic.
  • Brightens under my eyes, and I barely have any wrinkles. I just turned 55
  • Absolute best eye serum i have ever bought. Will definitely buy again and recommend.

Great product but I don't like the dispenser. It's a squeeze tube so a lot gets left inside. Would prefer a pump.

Still Early, But Loving It So Far

I've been using this eye serum for less than a week, so it's a bit early for a full verdict�but so far, I'm really enjoying it. The texture is noticeably richer and more indulgent than other eye creams or serums I've tried, and while it does take a little longer to absorb, it feels deeply hydrating and soothing. The packaging is stunning, and the iridescent finish adds a touch of glam to both my morning and evening routines. Excited to see the longer-term results!

Only product I can't do without

I have been using this product for over 15 years. It is the only product I have ever bought that I can't do without. Brightens under my eyes and I barely have any wrinkles. I just turned 55

Favorite Eye Serum

I absolutely love this eye serum! My skin is extremely sensitive, and I often react to eye products with contact dermatitis�but not with this one. As a licensed Esthetician and RN, I've tried countless products, and this is by far my favorite for plumping fine lines and maintaining a dewy, healthy glow. It also works beautifully to blur fine lines around the lips. Highly recommend

Let me know if you'd like it to sound more casual, technical, or targeted to a specific audience.
It is super dense, so if you are looking for something lightweight, or have trouble with raccoon eyes, this may not work for you.
