I would trust RCW's advice. My skin is beautiful now and it's all her doing. I won't let a product touch my face unless it's something that she's mentioned is okay.
But, this is all just my opinion and experience.
I love Jessicurl HCC, Jessicurl Too Shea, KCKT, KCCC, CK and HESMU...but it took a LOT of trial error to get to these products that consistently work for ME.
