The term 'emollient' specifically refers to a substance that softens and moisturizes the skin. Emollients work by forming a protective barrier on the skin's surface, which helps to lock in moisture and prevent water loss, leading to hydrated and more supple skin. These products are commonly used in skincare formulations to improve skin texture and alleviate dryness, making them essential for maintaining skin health.

In contrast, other choices present functions that pertain to different types of skin care products. For instance, substances that exfoliate the skin work to remove dead skin cells, which is not the primary role of emollients. Similarly, while some products offer sun protection, this is associated with sunscreens rather than emollients. Lastly, a matte finish is typically achieved through products like primers or powders that absorb oil, which also does not align with the moisturizing and softening properties associated with emollients.
