By far the best product I have ever tried, and I'm not just referring to the results - which I'm sure will be amazing - because I'm still in the beginning stages of using it. But the feeling it leaves on your skin is unmatched. I have been using the c tetra from the same company for years, which is wonderful. Now I got this one for a more enhanced effect and it is... just as I expected... the best serum I have tried on my skin, and I have tried many.

It is the vitamin C that I ended up with....
I was taking the C-Tetra Lipid Vitamin C from the same company, but it was of lower concentration and unfortunately in a small bottle.. as known, vitamin C oxidizes very quickly... it barely lasted 2 months even in a cupboard and with quick closing of the packaging after each application.... that's why I prefer this version because it comes in 2 bottles with a dropper.... it will definitely last longer.... wallet wise.
In terms of performance, EXCEPTIONAL, overall the company is a star in active ingredients!! ⭐️⭐️⭐️⭐️⭐️
