I usually stay acne free, unless I eat a LOT of sugars. If I have sugar I break out like there's no tomorrow
God I had that problem when I was first pregnant and it was horrible. I tried everything nothing seemed to help much because it's all hormone related. I tried all the products that are for spots, but because of all the chemicals etc in those products I found they made my skin worse. I ended up finding one product that worked for me though (and funnily enough it is for spot prone but wasn't harsh on the skin). It was the Nutrogena 2 in 1 mask and wash. I used it every day as a normal facial wash then once a week as a mask. It was great, and did help clear my skin up and make it feel so soft and nice. Simple face wash and moisturiser also helped because it was all natural stuff and non perfumed. Not sure if you get Simple products in the US though?
Oh and vitamin E! Great for the skin!
