7% L-Ascorbic Acid serum and Hydra B5 Complex starter kit.
DOES NOT WORK.
It didn't smooth out my wrinkles nor fade spots. And it deteriorates fast, so you gotta use it fast, since Ascorbic Acid is the most unstable and irritating form of vitamin C.
I read somewhere that pure vitamin C needs to be in a 10% concentration to work on collagen synthesis. Maybe that's why? But the 7% is definitely not effective. And pricey too!
