What function does egg white serve in a skin mask?

Egg white is primarily known for its ability to create a tightening effect on the skin when used in masks. The proteins present in egg white, particularly albumin, help to firm and tighten the skin upon application. This tightening can temporarily reduce the appearance of pores and provide a smoother look to the skin, making it a popular ingredient in various DIY beauty treatments.

The functional benefits of egg white masks can also include improving skin texture and reducing oiliness due to its ability to absorb excess sebum. However, the most notable and immediate effect is the tightening sensation experienced as the mask dries and pulls on the skin.

While egg white does have some nourishing properties due to its protein content, its primary and most recognized role in skin care is the aesthetic tightening effect it provides. Other options like moisturizing or exfoliating are more associated with different ingredients, such as oils or exfoliants, which do not align with the primary action of egg whites in a skin mask.
