This stuff is so lovely! I always buffer it with moisturiser - just in case, but it hasnt caused any dryness or flaking like retinols often do. It smells lovely, not strong or artificial, just fresh, and it sinks into my skin beautifully. My skin loves it, and the pores on my cheeks are looking clearer, and smoother, while the fine lines developing on my forehead also seem less obvious. I think it’s even working on the dark marks left by previous acne! I love this stuff!
