Medik8 C-Tetra Luxe Vitamin C Serum 1.0 fl oz — Squalane & Vitamin E, Lightweight Hydrating

Medik8 C-Tetra Luxe is a lightweight, stabilized vitamin C facial serum blended with squalane and vitamin E to support brighter-looking, hydrated skin without heaviness.

This daily serum combines a stabilized form of vitamin C with nourishing squalane and antioxidant vitamin E to help skin appear smoother and more even while providing immediate-feel hydration. Fast-absorbing and suitable for layering under moisturizer and SPF, the formula is vegan and gluten-free. It’s designed for everyday use by those seeking antioxidant support alongside lightweight moisture.

How does this serum help improve skin texture and tone?

The stabilized vitamin C in this serum works as an antioxidant to help protect against oxidative stress and to support a more uniform-looking skin tone. In combination with vitamin E, it helps the skin look brighter and refined over time while squalane keeps the surface supple so texture appears smoother.

• Stabilized vitamin C for lasting antioxidant activity
• Vitamin E to complement and enhance antioxidant benefits
• Squalane to soften and smooth skin surface
• Lightweight base that minimizes residue and supports layering

Will this serum feel heavy or leave a greasy finish?

No — the formula is engineered for fast absorption and a lightweight, non-greasy finish. Squalane is an emollient that mimics skin’s natural oils, delivering hydration without weight, so it layers comfortably beneath moisturizers and sunscreens.

• Fast-absorbing texture suitable for morning routines
• Squalane provides moisture without stickiness
• Works well under SPF and makeup
• Leaves skin balanced, not oily

How should I incorporate Medik8 C-Tetra Luxe into my routine?

Use the serum once daily in the morning after cleansing and before moisturizer and sunscreen. Apply a few drops to face and neck, allow it to absorb, then follow with your normal SPF for daytime antioxidant protection.

• Apply to clean, dry skin in the AM
• Use 2–4 drops for face and neck
• Allow a brief absorbtion period before moisturizer/SPF
• Suitable for daily use across many skin types

Is this product suitable for sensitive or vegan lifestyles?

The formula is vegan and gluten-free and crafted to be gentle while delivering antioxidant action and hydration. As with any active ingredient, patch testing is recommended for very reactive skin to ensure tolerance before full-face use.

• Vegan and gluten-free formulation
• Lightweight and generally suitable for many skin types
• Patch test advised for very sensitive skin
• Non-heavy texture lowers chance of pore-clogging

Who is this for: Medik8 C-Tetra Luxe is aimed at anyone seeking a daily antioxidant boost with added hydration—ideal for those wanting a brighter-looking complexion without heavy oils. It’s particularly useful for people who prefer fast-absorbing serums that layer easily under sunscreen and makeup, and for shoppers looking for vegan, gluten-free skincare options that support smoother, more balanced-feeling skin.
