I used to have really bad acne until a couple weeks ago; I started drinking more water and all of the bumps went away. But now, my face is constantly red and I have these red, flat, blotchy spots everywhere. Some days are worse than others, it's like it will flare up sometimes. My mom and I researched it and were convinced it was rosacea, but I went to a dermatologist and she said it was acne scars and put me on all of this treatment. But I'm still stuck on the rosacea thing, because I just can't understand how all of these "acne scars" would have popped up overnight and spread around.And I have ZERO pimples on my face, it's just redness and spots. So isn't it pointless to put me on acne medication? I can post pictures if needed.
