Am not really a user of masks,use it when i feel like it but nowadays try to use at least once a week. I am using the Rasberry root mask that comes in a bottle. Alot of rave about it. Since I don't have much experience and never tried many masks before, this was okay. I can leave it on overnight. One pump almost enough to cover face. pleasant scent. Skin feels more supple after use.Don't think it had any whitening effect, size of pores...maybe got a bit smaller. Need to use more frequently i guess. Price gone up since i bought it. For acne prone skin and oily skin i would go for mud mask.
