Yesterday I read about putting ACV on your arms for Keratosis Pilaris. So last night I mixed up some ACV and water, exfoliated my arms well and then put it on. It burned my arms, and just made them more red. I have a moderate/severe case of it, and I really want it to go away. Is the burning/initial redness normal? I know I've only done it once, but I'm wondering if it will eventually help. I'm also drinking an ACV/baking soda/water mix. I want to wear a dress in 2 days and I need my arms to look better. HELP! PLEASE!
