Love this product. I managed to get a sample for it and a sample can last u a really long time since u only need a wee bit each time. I was having a really dry looking eye area with some lines and after using this, I could see a difference even after 1 night. Eye area looks so much smoother & lines almost all gone! After 2 nights, no more lines! This absorbs well and so far, I've had no adverse reactions to it. HUGE RAVE! My staple from now. Use this at night and with the eye gel in the day for more oomph.
