My favorite skin care product on the market. The results were so apparent in just two weeks that I was surprised by my own reflection. I have very sensitive skin that is prone to redness and acne and this did not cause irritation or breakouts. It has a clean scent that isn't too chemical or too floral. This product is worth every penny they charge. Absorption Blends in well and doesn't feel greasy. I used it at night and left it on as I slept, then rinsed my face (no soap) and applied makeup in the morning. Doesn't Clog Pores I am prone to acne and have very sensitive skin. The product caused absolutely no irritation and no outbreaks. Effectiveness 100% Effective! There were major visible results after just two weeks of use. I used the product every night and was actually surprised when I went to put on make up one morning. I actually noticed the improvement myself. My skin was smoother and brighter than it had been in years.
