Philosophy has recently released a new miracle expert dark spot & pore whitening peel pen so thought id share my thoughts. I love the idea and even though it’s a bit premature, I feel like it would be quite effective. It seems high in acidity and is quite light. Put some of the liquid on problematic areas such as spots, scars and pores and voila. The only negative thing in my opinion is the applicator. It’s quite hard, leading the liquid to drip so not very easy to apply unless with a finger.
