What is the function of humectants in skin care products?

To add color to the skin
To attract water to the skin
To exfoliate dead skin cells
To protect against UV rays

The correct answer is: To attract water to the skin

Humectants play a crucial role in skin care products by attracting water to the skin. This property allows them to help retain moisture, which is essential for maintaining hydration and promoting a plump, healthy appearance of the skin. By pulling water from the environment and from deeper layers of the skin to the outer layer, humectants help to minimize dryness and enhance the skin's overall texture. In contrast, other functions mentioned in the choices are not the role of humectants. Adding color to the skin typically involves pigments or dyes, which are not related to the moisturizing function of humectants. Exfoliation of dead skin cells is achieved through the use of exfoliants, such as alpha hydroxy acids or physical scrubs, rather than through humectants. Protection against UV rays is provided by sunscreens containing specific agents that reflect or absorb ultraviolet light, which also does not relate to the hydrating action of humectants.
