What is the primary role of humectants in skincare products?

1. To provide shine

2. To attract moisture

3. To enhance absorption

4. To block UV rays

The correct answer is: To attract moisture

Humectants play a crucial role in skincare products by attracting moisture to the skin. This function is vital for maintaining skin hydration, as humectants draw water from the atmosphere or deeper layers of the skin to the outer layer. By keeping the skin's moisture levels balanced, they help prevent dryness and promote a plump, healthy appearance. Incorporating humectants into skincare formulations is particularly beneficial in environments with low humidity or for individuals experiencing dry skin conditions. Their ability to retain moisture not only enhances the skin's texture but also supports the overall efficacy of other active ingredients in the product. While other options mention benefits such as shine, absorption, or UV protection, these do not accurately describe the fundamental action of humectants. Their primary function remains focused on moisture attraction, essential for effective skincare.
