This mask is Aqualabel Whitening range, the color packaging is blue and...shiny.
I used it for about 30 minutes. The feeling is wonderful, no allergy, sensitiveness, or any discomfort while using the mask. I use it after cleansing and use the lotion from WT range too.
And the result is.............yes the picture are exactly like that, I didn't make any mistake by putting the before in after or the other way around.
Conclusion: Not all whitening mask gives instant gratification.
