You first place the circle sticker over the stubborn spot then apply the mask. The spot is supposed to provide extra treatment I guess.
The sticker was very thin and easy to apply.
I then applied the mask. When I took off the mask, the sticker had dissolved.
The mask made my skin feel soft but unfortunately there was absolutely no change to my sunspots, even after using all 6 masks.
I know removing pigmentation with skincare is really difficult but I thought this would help a little, especially with all the claims, but it did nothing and I was so disappointed.
Also, my spot is close to my eye so the sticker sometimes stuck out through the eye hole of the mask and did not dissolve fully. So I had to be careful to apply the sticker so it would fit under the mask but cover my spot.
Just too expensive for no results.
