I was skeptical at first about this product, but I used it for my friend's 21st, and usually, after a sip of my drink I would go extremely red TOMATO red, and it'll be from my face down to my neck. Surprisingly this time I did not go red at all, I felt a bit hot but when I went to the bathroom to look at myself I was nowhere close to being red. I will definitely be using this every time I drink it really works wonders.
