Smooth, Lift & Brighten Eye Cream with Gentle-Release Vitamin A
Medik8 Crystal Retinal Ceramide Eye Cream is available in three different strengths:
0.03%, and 0.06%. and 0.10%
The strength you choose will depend on your skin type and concerns. If you're new to retinol, I recommend starting with the lowest strength and gradually increasing as your skin tolerates it.
How to Use Medik8 CRYSTAL RETINAL CERAMIDE EYE CREAMS
To use the Medik8 Crystal Retinal Ceramide Eye Cream, apply a small amount to your ring finger and gently pat around the eye area. Use in the evening after cleansing and toning, and before your moisturiser.
Start by using it twice a week and gradually increase as your skin tolerates it.

With regular use of the Medik8 Crystal Retinal Ceramide Eye Cream, you can expect to see a reduction in the appearance of fine lines, wrinkles, and dark circles.
Your skin will appear plump, hydrated, and youthful, with a smoother texture and more even tone.

Hyaluronic Acid Filling Spheres
A breakthrough form of hyaluronic acid that is able to fill in and smooth the look of fine lines and wrinkles, and expand within the depth of the wrinkle to give the appearance of plumpness.

How It Works

Medik8 C-Tetra and C-Tetra Luxe serums are formulated with Tetrahexyldecyl Ascorbate, a powerful and stable form of vitamin C. This supercharged antioxidant not only neutralises free radicals but also stimulates collagen synthesis to reduce fine lines and promote a firmer, more youthful look.
Together with vitamin E, these serums form a “network antioxidant” system, offering enhanced protection and a healthy, glowing complexion throughout the day.
Why Choose Medik8 C-Tetra Serums?
- Advanced formulas for daily radiance and long-term skin health
- Perfect for all skin types, including sensitive skin
