### ⭐⭐⭐⭐⭐ Great
*by T***M on 17 June 2020*

I have very dry skin and this has helped immensely!!! Does not clog pores and you only need to apply a small amount before putting on your regular moisturiser. Just be careful in the beginning that you don’t use too much serum that’s on the piper when the bottle is full as you will run out faster
