Regular price $74.95Medik8 C-Tetra 30mL is a vitamin C antioxidant serum. A stabilised vitamin C derivative works alongside vitamin E to support a brighter-looking complexion and daily antioxidant care, with jojoba oil providing emollient nourishment. It is a useful entry point for someone building a morning vitamin C routine and wanting a serum that fits before moisturiser and sunscreen. The oil-based formula adds a focused radiance step, particularly when dullness and early visible ageing are priorities rather than exfoliation alone.
A lightweight oil-based serum for the morning, applied before moisturiser and SPF.
These are selected key ingredients. Check the product packaging for the complete ingredient list and any formula updates.
Antioxidants complement sunscreen but do not replace it.
How does C-Tetra differ from C-Tetra Luxe?
C-Tetra is the lighter entry point in this vitamin C range. Luxe combines a higher vitamin C concentration with additional nourishing lipids.
