I received this from the Skin Ceuticals House of Skin community for testing and reviewing. I have combination skin, with oily T-zone specially the nose. I have been applying this serum every morning as the first layer before makeup and To my surprise the serum helped regulating the shininess on these areas without drying the skin. Foundation stays flawless for longer hours. I could also see some of the recent acne mark started to fade. I just love how it controlled all the extra sebum and makes the makeup even better and smoother with less visible.
