We love this pHaze 9 Purifying Mask from Scottsdale-based PCA Skin. The instructions say to use this treatment weekly but we find if once is good, daily is better. After using this Red Sea algae, French Clay based exfoliant on our neck daily for the last week we have seen a remarkable decrease in some nasty acne. We had a laser treatment at the Doctor's office that caused a massive breakout. Ego-crushing, really. But only one week later this mask has left us with a new favorite brand. This mask will nourish rough, dull, dehydrated and stressed skin, and also help clear breakouts. Plus, the addition of micro fine pumice allows for the gentle exfoliation of impurities. Enjoy!
