Review (5/5): Easy to use, no irritation, natural looking, boom.
What else do you need to know? No, seriously, it's all right there in the title.
I would advise using this BEFORE hopping into the shower... it is MUCH easier to remover the residue in the shower than to wash my face off in the sink. I can't say for sure how long the product lasts, I usually do a new layer maybe once a week
