Used up my last container so repurchasing. The mask feels gentle on your face and smells really nice. I don't know if it's actually lightened any of my brown spots, but no new ones have appeared either.
Tried this for the first time today from a sample in the recent Nordstrom gift with purchase promo. The mask dried up in a minute. Struggled with the cleaning afterward. Tried to wash off with warm water but it a layer of greasy but not oily residue on my face. Some of the reviewers said it was sticky and other said came right off. But later the day I saw small white bumps near corners of my mouth and nose, might be the residue cause a reaction on my skin. Overall, couldn't say anything about the effectiveness of the whitening benefit, but first experience of this product I'm not very pleased.
