Think of this as a botanical Retin-A. It addresses the same range of concerns but without the irritation and dryness that quite often comes with Vitamin A derivatives: dries up my adult acne, smooths my skin, and clears my pores so they look smaller in the morning. It does not dry my skin and it helps to control its oily tendencies throughout the day. Give your skin time to adjust to the product and let it calm down to really see its benefits. I use this every other night (alternating with Darphin's Aromatic Purifying Balm). Last thing, a little goes a long way, so while the tube might seem small it will last a long time. "
