Which of the following is a function of humectants in skincare?

Humectants play a vital role in skincare by attracting moisture to the skin. These ingredients have the ability to bind water from the environment and draw it into the skin, which helps to keep it hydrated and plump. This function is particularly important in preventing dryness, maintaining skin elasticity, and ensuring a healthy appearance.

Understanding the importance of moisture can help estheticians when recommending products based on a client's skin type and concerns. Humectants are often used in moisturizers, serums, and hydrating treatments to enhance the skin's hydration levels. This positive effect on hydration can contribute significantly to overall skin health and comfort, making humectants a fundamental component in effective skincare formulations.
