Hello, I ordered this product and I also have the retinol from the same series. Should I apply this product on my face first in the evening and then the retinol?

Medik8 C-tetra

I think the product spreads well and four drops are enough for the face. It absorbs quickly and using this doesn't really take any more time in the morning. Refreshes the face.

Nice to hear!

Promising product

The product seems promising, but I have difficulties applying four drops evenly on the face. I have mixed them into my day cream or under the serum I sometimes apply, and this works well. Is this okay? When the instructions say to apply directly to the face.

Hello, if the skin is dry, it might be that 4 drops of serum are not enough. C-Tetra works best when combined with Medik8 retinol in the evenings. Then the skin surface is receptive to products. The absorption of C-Tetra weakens if mixed with cream, so it is not recommended.

Pleasant product, strange age recommendation

Very pleasant-feeling product and reduces hyperpigmentation, but why is the recommendation for 20-40-year-olds??

Tiba, really great if it reduced hyperpigmentation. Those age recommendations for Medik8 products are indeed peculiar and have received feedback before. You should always contact us if the product recommendations are concerning.

C + E Vitamin Antioxidant Serum

  • Protects the skin from free radicals
  • Stimulates collagen and elastin synthesis
  • Reduces hyperpigmentation
  • Prevents premature skin aging

    Restore your skin's healthy glow and prevent visible signs of aging with the ultra-light C-Tetra serum suitable for daily use. C and E vitamins ensure the serum's effective antioxidant properties. Together, these active ingredients protect against environmental and sun-induced damage. The light, firming serum stimulates collagen and elastin production, and helps reduce wrinkles and fine lines, smoothing the skin's texture and tone. By using the fat-soluble tetrahexyldecyl ascorbate form of vitamin C, the active ingredients penetrate deep into the skin, providing effective antioxidant protection without skin irritation. C-Tetra is precisely formulated, water-free, and 100% stable, preventing the breakdown of vitamin C over time. This ensures that the serum remains as effective from the first use to the last drop. 


    Usage

    Designed to be used directly on the skin. In the morning after cleansing, dispense 4-5 drops directly onto your hand and apply evenly to the face, neck, and décolleté. Allow to absorb for 2-3 minutes.

    Active Ingredients

    Tetrahexyldecyl Ascorbate – A fat-soluble form of vitamin C that provides exceptionally strong antioxidant protection against harmful free radicals, while stimulating collagen production to maintain youthful skin.

    Vitamin E – A fat-soluble antioxidant naturally present in the skin. Vitamin E protects the skin from free radicals and reactivates vitamin C to achieve optimal effectiveness.
