What effect does collagen have on the skin?

1. It weakens skin structure

2. It provides support and elasticity

3. It causes skin dryness

4. It leads to excessive oiliness

The correct answer is: It provides support and elasticity

Collagen is a vital protein that plays a crucial role in maintaining the skin's structure, firmness, and elasticity. As a major component of the skin, it serves as a scaffold that supports skin cells and helps to maintain the skin's overall resilience and youthful appearance. The presence of collagen allows the skin to stretch and bounce back, which is essential for a healthy and vibrant complexion. As the body ages or is subjected to environmental stressors, collagen production can diminish. This reduction contributes to the appearance of fine lines, wrinkles, and sagging skin. Therefore, collagen is inherently linked to the skin's strength and flexibility, reinforcing its importance in maintaining both support and elasticity. In contrast, options that suggest weakening skin structure, causing dryness, or leading to excessive oiliness don't align with the scientifically established functions of collagen. While other factors may influence skin health—such as hydration levels and oil production—collagen specifically plays a supportive role that enhances the skin's integrity and elasticity.
