The black color of the mask comes from the color of the material itself, not the dye. Therefore, it will not change color or dye after touching the skin like some dyes. Of course, when using any mask, the skin may have some natural reactions, including temporary redness or irritation, but these have nothing to do with the color of the mask.

Generally speaking, the black mask cloth of Youyan Black Spring Mask will not make the skin darker. Please use according to your skin condition and doctor's advice.
