Experience
This is a really solid skin care company, pricey but worth it. I have sensitive combination skin and these products did not make me break out. Good Genes lactic acid is good for declogging and smoothing. It is strong, so go easy on it and give your skin time to adjust between uses. The instructions suggest applying Good Genes on top of Luna Sleeping Night Oil, which really intensifies the effects of Good Genes. Luna Sleeping Oil is one of the few retinols that I have found to be moisturizing. A little goes a long way with Luna.
