I started using this when I got some as a sample. I am 35 and have oily skin, I use it in the morning after cleansing and vitamin C and before moisturiser and SPF. I really like it. One and a half pumps does my whole face a neck. It absorbs into the skin quickly and doesn't feel thick, oily or yuk. The results I've noticed is tighter and brighter skin. I really like it and will continue to use it.
