What is the primary function of emollients?

1. To provide immediate hydration to the dermis

2. To penetrate the outer layer and soften the skin

3. To exfoliate dead skin effectively

4. To tighten and firm the skin

The correct answer is: To penetrate the outer layer and soften the skin

The primary function of emollients is to penetrate the outer layer of skin and soften it. Emollients work by forming a protective barrier on the skin's surface, which helps to trap moisture and prevent water loss. This action not only contributes to the hydration of the skin but also improves its overall texture and elasticity, making it feel smoother and more supple. While other options mention various skin benefits, such as hydration or exfoliation, they do not align with the specific role of emollients. Emollients are not designed primarily for immediate hydration, as their primary function is to reduce dryness by softening the skin layers over time. Additionally, they do not perform the function of exfoliating dead skin or tightening and firming the skin, which are roles typically associated with different types of skincare products. Therefore, option B accurately captures the core purpose of emollients within the context of skin care.
