The core principle of makeup removal is "oil dissolves oil." Most makeup products are oil-based or waterproof, and cannot be dissolved by water alone. Therefore, they need to be broken down with the help of oils or surfactants.
Common makeup removal methods include:
Oil dissolution: Makeup remover oils use oil-soluble components to dissolve makeup.
Surfactant emulsification: Makeup remover water/lotions remove dirt through emulsification.
Physical wiping assistance: Cotton pads help remove residue.
Emulsification is a crucial step, especially for makeup remover oils. If emulsification is insufficient, residue can easily remain, clogging pores.
