Does anyone here check out products on Paula's site before using them? Do you agree with her reviews? Is she usually spot on? I am tired of spending hundreds of dollars on products that make great claims but don't actually do anything. A product may have 10% AHA but if the pH is too high, it won't do much of anything. It is very hard for a consumer to determine the pH of most products out there. (That's just one example.) So, is Paula's advice usually quite good or do you find she steers people toward her own line of products?
