COSMEDIX Under Eye Serum Opti Crystal — Lightweight Brightening & Hydrating Serum for Dark Circles and Puffiness

COSMEDIX Opti Crystal Under Eye Serum is a lightweight liquid-crystal serum designed to hydrate, brighten the under-eye zone and visibly reduce the appearance of puffiness, dark circles, and fine lines when used day and night.

This concentrated eye serum pairs liquid crystal technology with antioxidants and hydrating actives to nourish the delicate skin around the eyes. Fast-absorbing and suitable for AM and PM routines, the formula is cruelty-free and developed to integrate easily under makeup or layered with other skincare products. It’s presented in an easy-dispense format so you can apply a precise, small amount where skin needs targeted support.

How should I use this serum in my morning routine?

Apply a pin-sized drop in the morning after cleansing and before sunscreen or makeup. Pat gently with your ring finger to avoid tugging; allow the serum 5–10 minutes to absorb fully for a smooth base under makeup.

• Use a pin-sized amount per eye to avoid over-application.
• Apply after toner/essence but before moisturizer and sunscreen.
• Wait 5–10 minutes for full absorption under concealer or foundation.
• Gently tap with the ring finger—no rubbing or pulling.

Will this help with puffiness and dark circles?

The serum is formulated to address common signs of fatigue around the eyes by combining hydrating liquid crystals with antioxidant support. While individual results vary, the formula aims to decongest and brighten the area’s appearance when used consistently.

• Hydrating actives help plump and smooth fine lines.
• Antioxidants support skin resilience against environmental stressors.
• Lightweight texture helps reduce visible puffiness and shadowing.
• Designed for twice-daily use to maintain results over time.

How does the texture and packaging make application easier?

Opti Crystal has a thin, liquid-crystal texture that absorbs quickly without leaving residue, making it ideal to layer under makeup. The dispenser delivers controlled micro-doses so you can apply exactly the amount needed to the orbital bone and under-eye triangle.

• Liquid-crystal texture for rapid absorption and a smooth finish.
• Precision dispenser prevents waste and over-application.
• Non-greasy feel suitable for all skin types and tones.
• Works day and night; pairs well with other COSMEDIX treatments.

Is this serum safe for sensitive skin and daily use?

COSMEDIX formulates with gentle, plant-forward ingredients and avoids unnecessary irritants; however, patch testing is recommended for very reactive skin. Designed for daily AM/PM use, the serum is cruelty-free and created to be layered within a broader skincare regimen.

• Formulated with clean, plant-derived ingredients and antioxidants.
• Cruelty-free brand standards and dermatologist-trusted formulation approach.
• Patch test first if you have extreme sensitivity or known ingredient reactions.
• Compatible with common skincare steps like moisturizers and sunscreens.

Who is this for: COSMEDIX Opti Crystal Under Eye Serum is aimed at anyone seeking a lightweight, hydrating eye treatment to smooth fine lines, reduce the look of puffiness, and brighten the under-eye area. It suits customers who want a clean, cruelty-free product that layers well with makeup and other skincare steps, from those beginning anti-aging routines to people needing a targeted boost for tired-looking eyes.
