Vitamin C Alternative
I am allergic to everything under the sun and I don't tolerate Vitamin C very well. This product is the only Vitamin C that hasn't made me break out. I plan to try more with the 3-0 Ethyl Ascorbic Acid version, but this is my go to in the meantime. I definitely don't have any chemical burns or sensitive reactions to this. It's my go to daily use for the summer!
