Peerless is a maximum quality highly concentrated Hyaluronic acid formula designed to give you results you can see and feel. Designed to target wrinkles and skin imperfections around the eyes and on other noticeable areas of the face. I bought 6 for the discount but its taking ages to get through them. This old style bottle sometimes clogs on the pump, but I just undo the lid and use it that way. It's brilliant for my mouth and eye lines. I use it before I moisturize. P42
