I like it because, unlike other serums that contain the pure form of vitamin C, this one is not oily at all, has a very light and pleasant texture, and is easily absorbed into the skin. I tolerated it wonderfully, it did not cause me acne (as happened in the case of those with an oily base) and I saw results from the first applications.
The first result that is immediately noticeable is a brighter and smoother complexion. My skin instantly became "clearer" and brighter, so I looked more rested, fresher. I also noticed an improvement in firmness. Thanks to the high concentration of vitamin C and the rich content of active ingredients, by using the serum regularly, my skin becomes softer and more hydrated, glowing with youth.
