I love Purpose. My dermatologist recommended it to me and actually, many dermatologists do. It is pure, nothing irritating or comedogenic and you can get it at Target or
Walmart for around $4.00 a bottle. My skin is very sensitive and it hasn't ever bothered me. The money I save on this, I spend on my face creams. The way the dermatologist explained it was don't spend a lot on something you wash right off. Spend it on the things that stay on your face. So, I do.
