Skin is primarily made of keratin, a tough, fibrous protein that also forms the structure of hair and nails. Keratinocytes, the most abundant type of skin cell, produce keratin. This protein helps to provide skin with its strength, resilience, and protective barrier.
While keratin is the dominant protein in skin, other proteins play important roles as well. Collagen provides strength and structure, while elastin allows for flexibility and elasticity.
In addition to these major proteins, the skin also contains fibroblasts, which produce collagen and elastin. These cells help maintain the skin's structural integrity and contribute to its overall health.
In summary:
- Keratin: The primary protein found in skin, hair, and nails.
- Collagen: Provides strength and structure to the skin.
- Elastin: Allows the skin to stretch and bounce back.
- Fibroblasts: Produce collagen and elastin.
