The experts at NERD Skincare got their hands messy in the science lab to create the ultimate line of innovative facial treatments. The secret? Each mask is made of biocellulose, an all-natural material that acts like a second skin. Its lightweight structure is composed of super-fine fibers that are thinner than a strand of hair and cling closely— but comfortably—to skin to create a vacuum that opens up pores. Translation: These no-nonsense treatments ensure maximum absorption of skin-nourishing ingredients that moisturize, brighten, and repair.
