Great Part of Everyday Routine!
I felt like I splashed out when purchasing this product as it’s a little more expensive than what I’d usually buy, but I’m so glad I did! This serum feels a bit like an oil, and is such a relaxing and luxurious addition to my skincare. I find it absorbs after a minute or two, and is a great way to introduce a little facial massage into my morning routine. My skin looks healthier and more glowy since I have started using this product and I will definitely be repurchasing once it runs out.

Amazing
I love it most of all because it gentle for my sensitive skin. It sits well and doesn’t cause any piling or discolouration on skin. It doesn’t oxidise and has no smell. I thoroughly recommend espresso for sensitive skin.

Medik8 bit C tetra serum
Absorbs nicely into skin, non sticky. Skin Feels nourished and a lovely base for make up. It is expensive for the amount you get but it does go along way as only few drops needed. Exploring more of the range as very pleased with the effects from this serum.

Very optimistic about this product
its early days but I'm pretty convinced its working. I'm combining facial exercise with the serum + improved nutrition and can see skin is firming up, less saggy and looks brighter. Pigmentation also improving. Will definitely continue use.
