Collagen is a vital protein that makes up approximately 70% of the dermis, which is the second layer of the skin situated beneath the epidermis. Collagen provides structural support, strength, and elasticity to the skin, making it crucial for maintaining the skin’s overall firmness and resilience. It plays an essential role in the skin's health, helping to prevent sagging and wrinkles.

In addition to providing support, collagen also serves as a scaffold for other components such as elastin and hyaluronic acid, which contribute further to the skin’s texture and hydration. By understanding the predominance of collagen in the dermis, skincare specialists can better appreciate its importance in anti-aging treatments and overall skin health.
