What substance makes up 70% of the dermis?

Collagen is the primary structural protein found in the dermis, making up approximately 70% of its composition. This fibrous protein plays a crucial role in providing strength, elasticity, and resilience to the skin. It forms a dense network that helps support skin structure and contributes to the overall firmness and suppleness of the skin.

Collagen production is vital for maintaining skin health, and as we age, natural collagen synthesis decreases, leading to signs of aging such as wrinkles and sagging skin. Understanding the significance of collagen in the dermis highlights its importance for skincare professionals and reinforces the need for treatments that promote collagen production or utilize collagen-based products.

While water and elastin are also components of the dermis, they do not make up the majority of its composition. Water is essential for skin hydration and overall health but is found more abundantly in the epidermis. Elastin provides elasticity and flexibility to the skin, but it constitutes a much smaller percentage compared to collagen. Protein is a broad category that includes various types, but it is not specific enough to represent the predominant substance in the dermis, which is collagen.
