COSMEDIX Opti Crystal Under Eye Serum - Brightening & Depuffing Eye Treatment, Lightweight Hydrating Formula

COSMEDIX Opti Crystal Under Eye Serum is a lightweight liquid-crystal serum designed to visibly brighten dark circles, reduce puffiness, and hydrate fine lines around the eye area.

This concentrated AM/PM eye serum blends hydrating and antioxidant-rich ingredients with liquid crystal technology to target common under-eye concerns like discoloration, mild sagging, and dryness. The silky texture absorbs quickly, layers under makeup, and is formulated cruelty-free with a focus on gentle, high-performance actives. Use a pin-sized drop each morning and evening to support a smoother, more rested-looking eye contour.

How does this serum address dark circles without harsh ingredients?

The formula combines brightening and antioxidant components with a delivery system that helps actives sit well on delicate eye skin. Instead of abrasive exfoliants, it relies on hydration and supportive ingredients to improve the appearance of shadowing and uneven tone over time.

• Liquid crystal technology helps deliver hydrating actives for immediate radiance.
• Antioxidants protect skin from environmental stressors that deepen discoloration.
• Lightweight, non-greasy finish layers smoothly under concealer and foundation.

Will Opti Crystal reduce puffiness and improve firmness?

The serum is formulated to temporarily smooth and support the look of the under-eye area; it minimizes the appearance of puffiness by hydrating and helping skin look firmer and more lifted. Consistent use supports a refreshed appearance rather than an instant clinical tightening.

• Hydrating molecules plump and smooth fine lines for a firmer visual effect.
• Soothing components calm morning puffiness and stress-related swelling.
• Suitable for AM and PM routines to support round-the-clock care.

How do I use it so it layers well with makeup?

Apply a pin-sized drop on the ring finger and gently pat around the orbital bone to spread product without tugging. Allow 5–10 minutes for the serum to fully absorb before applying concealer or foundation to prevent pilling and ensure even coverage.

• Use a very small amount under daytime makeup to avoid creasing.
• Pat gently—do not rub—to protect delicate skin.
• For evening use, apply slightly more to the entire under-eye area for overnight hydration.

Is this product clean and cruelty-free?

COSMEDIX emphasizes clean formulations and avoids animal testing; the serum follows the brand’s commitment to safe, plant-forward ingredients and dermatologist-trusted chemistry. The company has prioritized gentle actives since its founding, making this a fitting choice for conscious shoppers.

• Formulated with a focus on purity and gentle performance.
• 100% cruelty-free; aligns with clean-beauty principles.
• Designed by skincare professionals and used by aestheticians.

Who is this for: COSMEDIX Opti Crystal Under Eye Serum suits anyone looking to brighten and hydrate the delicate eye area without heavy creams or aggressive ingredients. It’s ideal for those who wear makeup and need a fast-absorbing base, people experiencing mild puffiness or early fine lines, and buyers who prefer clean, cruelty-free skincare. If you want a lightweight, everyday serum to support a fresher, more awake-looking eye contour, this product is formulated for that purpose.
