Medik8 C‑Tetra Luxe Vitamin C Face Serum 1.0 fl oz — Lightweight Brightening with Squalane & Vitamin E

Medik8 C‑Tetra Luxe is a lightweight daily vitamin C face serum that combines a stable form of vitamin C with squalane and vitamin E to brighten skin appearance and deliver hydration without heaviness.

This serum blends a stabilized ascorbyl tetraisopalmitate derivative of vitamin C with moisturizing squalane and antioxidant vitamin E in a fast‑absorbing base. It’s designed for everyday use in morning routines, layering easily under moisturizers and sunscreen, and is formulated vegan and gluten‑free for broad compatibility.

How does this serum fit into my morning skincare routine?

Use Medik8 C‑Tetra Luxe after cleansing and toning, before moisturizer and SPF. Its light texture absorbs quickly so it won’t pill under layered products, helping your daily protection and hydration steps perform better.

• Apply 2–3 drops to clean, dry skin each morning.
• Allow 20–30 seconds for absorption before moisturizing.
• Follow with broad‑spectrum sunscreen for daytime antioxidant support.

What key ingredients make it effective for brightness and hydration?

The formula centers on a stable vitamin C derivative that targets skin radiance while vitamin E supports antioxidant activity. Squalane delivers lightweight, long‑lasting moisture to help skin feel soft without leaving an oily residue.

• Stabilized vitamin C derivative for improved skin tone and luminosity.
• Vitamin E to complement antioxidant benefits.
• Squalane for fast‑absorbing, non‑greasy hydration.

Is Medik8 C‑Tetra Luxe suitable for sensitive or combination skin?

Formulated for a wide range of skin types, this serum is lightweight and non‑heavy, making it appropriate for combination and oilier skin, while its hydrating components help drier skin feel comfortable. As with any active product, patch testing is recommended if you have known sensitivities.

• Vegan and gluten‑free formulation for broader compatibility.
• Non‑heavy squalane base reduces likelihood of pore congestion.
• Patch test on a small area before full use if you have reactive skin.

How quickly will I notice results and how should I store it?

Visible changes in skin brightness and texture may be noticeable within a few weeks of consistent morning use, though individual responses vary. Keep the bottle cool and tightly closed, away from direct heat and sunlight to preserve ingredient stability.

• Use daily in the morning for best antioxidant support.
• Expect gradual improvements over weeks with consistent application.
• Store in a cool, dry place and secure the cap after each use.

Who is this for: Medik8 C‑Tetra Luxe is suitable for anyone seeking a gentle yet effective daytime vitamin C serum that adds hydration without heaviness. It’s a good choice for users who want an everyday brightening step that layers well under moisturizers and SPF, and for those preferring vegan and gluten‑free skincare options.
