I bought this mask with over 10 different paper/tube masks from Sasa at the same time.
This mask (come with 5 pieces) was $10.40 U.S. on sale. The mask is pretty soaky wet when I got the mask from the pouch. The scent is like yogurt. I applied this on my face (unfortunately, this is a face mask without the neck potion) and massage the remaining fluid from the pouch to my neck/hands.
Forgot to mention, I usually cleanse the face, and then apply whitening or hydrating toner and put some eye mask from the tube before I place the mask on my face.
It's about $2.08 per mask, quite cheap. It's quite hydrating. I left the mask on my skin at least 20 minutes. The 1st time after use, the skin looks clear and refreshed. I can't tell too much about the lightening effect.
Hydration the skin is very important after using whitening mask. I found that most of the whitening mask dries out the skin. My moisture masks include Clarins Moisture Quenching Hydra-Care Cream (for combination skin)
Eye treatment: Lancome Primordiale eye cream and Sisley Eye and Lip Balm
I have sensitive skin and this mask doesn't break me out. Usually, I use whitening mask only when my skin condition is pretty good. Most of the whitening masks are more irritating than the hydrating masks.
Based on the first-time use, I don't think that I would repurchase again. Maybe if I use more often, the mask will have more effect on my skin. I will update this post later on.
Update after two day using the mask: My face seems to be brighter and lighten using the same skincare routine that I have been using. It seems that this mask takes the skincare product more absorbing. The whitening/brightening effect lasts for two days.
