When is the best time to use face masks? e.g before bed,morning?

when should i use it, ive got the montagne jeunesse blemish mud


should i use it in the morning before a bath or before i go to bed?


thanks|||I use them before bed. I clean my face and then apply the mask. Nice and refreshing, a lil pampering before sleep lol|||before bed to get all the makeup and dirt in the air from your face
