Chloroplasma by Perricone MD is the mask I use most. During the warmer months my skin is a combination skin type. When its hot out my skin is oily in my T-zone, and normal else where. The pores in my nose get congested. I also have some dark spots on my cheeks that need brightening. This mask helps with clearing and tightening up my pores. My skin looks radiant after using this mask. I apply a thin layer on clean skin and leave on for 5-10 minutes, then remove with warm towel.
