"Medik8 have a whole range of vitamin C options, and my favorite is their C-Tetra Advance, which uses a vitamin C derivative alongside other brightening agents. This is fantastic. Medik8 are leading the way when it comes to vitamin C innovation, and all of their vitamin Cs are so well formulated and so well thought through."

"Medik8 C-Tetra Advance is a very powerful yet gentle vitamin C formulated with THD ascorbate. [...] It's going to help brighten and provide antioxidant benefits, is lightweight, non-occlusive, and great if you're looking for a more fancier version with higher potency. [...] This formula contains 20% THD ascorbate, so a higher concentration and more potent, potentially offering better brightening or antioxidant benefits, [...] but nevertheless, I still don't find it very irritating. If you have sensitive skin, THD ascorbate formula because of the lipid solubility in the creamy version is going to be less irritating."
