What is the function of egg white in a facial mask?

• A. To hydrate the skin
• B. To add fragrance
• C. To create a tightening effect on the skin
• D. To exfoliate

Answer: (C)

Egg white acts as a temporary tightening agent because its proteins, mainly albumin, coagulate as the mask dries and form a thin film on the skin. This film creates a slight pull on the surface, giving a firmer feel and making pores look momentarily smaller. It does not provide hydration, nor does it exfoliate; it isn’t used for fragrance either. Keep in mind that raw egg can pose a food-safety risk, so professional products often use pasteurized formulations or alternatives to achieve the same tightening effect.
