Cosmedix Opti Crystal Liquid Crystal Eye Serum 7ml

Description
Eye serum with Liquid Crystal Technology for dark circles
The skin around the eyes is up to ten times thinner than the rest of the face and contains hardly any sebaceous glands. This explains why signs of fatigue, lack of sleep, and aging first become visible there: dark circles, fine lines, crow’s feet, and a dehydrated texture that no longer reflects light evenly. A heavy eye cream is rarely the right answer here — the delicate area requires a formula that works intensively without weighing down or migrating into the eyes.
Cosmedix Opti Crystal is a lightweight eye serum that combines the award-winning Liquid Crystal Technology with Spin Trap antioxidant and copper peptides. The biomimetic structure mimics the skin’s natural lipids, allowing hydration and active ingredients to be efficiently absorbed without a greasy or heavy finish. The silky serum is easy to dose with a dropper, absorbs quickly, and is suitable for wearing under makeup.
Benefits
- Reduces the visibility of dark circles and crow’s feet
- Deeply hydrates thanks to Liquid Crystal Technology
- Protects against environmental damage with Spin Trap antioxidant
- Supports a firmer appearance with copper peptides
- Suitable for the sensitive eye area and can be worn under makeup
Active ingredients
Liquid Crystal Technology: A biomimetic formulation technique where cholesteryl esters arrange themselves into a liquid-crystalline structure, identical to the skin’s natural lipid matrix. This structure slowly releases hydration and active ingredients, providing a long-lasting moisturizing effect that supports the skin barrier around the eyes.
Spin Trap (Phenyl T-Butylnitrone): A high-quality antioxidant that captures free radicals before they can react with skin cells. Protects the eye contour against oxidative damage from UV radiation, blue light, and pollution — three factors that directly contribute to premature wrinkle formation and dull discoloration.
Copper peptide complex: Copper gluconate supports the natural production of collagen and elastin in the skin, contributing to a firmer-looking eye contour. Particularly valuable for early sagging and visible lines.
R-lipoic acid: A powerful antioxidant that is soluble in both water and fat, allowing it to work in all layers of the skin. Enhances the effect of Spin Trap and vitamins, and helps reduce the visibility of pigmentation spots around the eyes.
Eclipta prostrata (false daisy) extract: A soothing botanical extract from the Ayurvedic tradition, with antioxidant and skin-calming properties. Helps balance the sensitive eye contour and contributes to a refreshed appearance.
Rice bran and moringa oil: Two light, nourishing oils rich in essential fatty acids and vitamin E. They nourish the eye contour and keep the skin supple without leaving a greasy film or migrating into the eyes.

Frequently asked questions
What is the difference between Opti Crystal and a classic eye cream?
Opti Crystal is not a cream but a lightweight oil serum that penetrates deeper than a conventional eye cream thanks to Liquid Crystal Technology. The texture is silky soft and does not migrate into the eyes, while the hydration level lasts longer than with a watery formula.
When will I see the first results?
The first moisturizing effects are noticeable immediately after application — the skin looks plumper and radiant. For visible improvement of dark circles, fine lines, and firmness, daily use for four to eight weeks is recommended.
Is Opti Crystal suitable for sensitive skin or after a professional treatment?
Yes. The formula is deliberately mild without retinol or acids, making Opti Crystal suitable for sensitive skin and for use after a peel or professional treatment. The Liquid Crystal Technology actually supports the recovery of the skin barrier.
Can I combine Opti Crystal with other eye products like Eye Genius or Eye Doctor?
Yes. Opti Crystal mainly works on hydration and protection, while Eye Genius targets dark circles and puffiness with peptides, and Eye Doctor focuses on firmness and deeper lines. Many users combine Opti Crystal in the morning with Eye Genius or Eye Doctor in the evening for a complete eye routine.
How long does a 7ml tube last?
With daily use twice a day, a tube lasts about three to four months. The small drop sufficient for both eyes makes the product economical to use.
