Mask, the most basic thing is to replenish water, and it can only replenish water on the epidermis, but deep hydration can't reach it. The most effective type is to add whitening, soothing or anti-wrinkle ingredients. Pay attention to wrinkle resistance rather than wrinkle removal. These ingredients can only reach the surface layer of the skin, but not the deep layer of the skin, and the effect can be imagined. If you want to improve the deep-seated problems, you still have to rely on medical beauty, and the mask only plays an auxiliary role.
