I used the vitamin C serum once. My skin was burned over the entirety of my face. It itched horribly. I had to see a dermatologist. I am now using the mountain glow moisturizer again after weeks of slathering my face with Aquafor. I do like other products by Ursa Major, but never again with the vitamin C serum.
