i bought this for myself and its my holy grail product a little luxury.This mask is full of antioxidants and vitamins.Im really a dermalogica junkie,cant get enough of their products.I use this once a week i want it to last longer,its so expensive! what i like about it,it gives my skin a nice glow and leaves it healthy. Sometimes i even sleep with it and wash it off in the mornings, i believe it can do wonders during the night because then it penetrates better,the skin is repairing itself a night time.love it
