What is the function of facial oils in a skincare routine?

Facial oils play a crucial role in refreshing and revitalizing the skin by providing deep moisturization and nourishment. They typically contain a blend of fatty acids, vitamins, and antioxidants, which help maintain the skin's natural barrier and retain moisture, making the skin appear healthier and more radiant. Additionally, they can enhance skin vitality by delivering essential nutrients that promote rejuvenation and repair.

While some other options may relate to skincare functions, they do not align with the primary role of facial oils. For instance, facial oils are not designed to remove makeup, function as a sunscreen, or directly influence the skin’s pH balance, which are the roles of other specific products such as cleansers, sunscreen, or toners. Thus, their main contribution to a skincare routine lies in moisturizing and nourishing the skin effectively.
