what is collagen in skin

Collagen is a protein that plays a crucial role in the structure and function of various parts of the body, including the skin, cartilage, bones, and connective tissues. It accounts for about 30% of the bodys total protein and provides structure, support, and strength to the skin, muscles, bones, tendons, and ligaments. As people age, the body gradually makes less collagen, leading to changes in the deep skin layers and a decrease in skin elasticity. Collagen works with other substances, such as hyaluronic acid and elastin, to maintain skin elasticity, volume, and moisture, and it also helps make up proteins such as keratin that form skin, hair, and nails. While collagen supplements claim to improve skin elasticity, reduce visible wrinkles, and increase blood flow to the skin, scientific research on the effectiveness of these supplements is lacking. However, a well-balanced diet, including foods like chicken, beef, fish, dairy, eggs, beans, leafy greens, and other vegetables, can provide the raw ingredients needed to help the body make collagen naturally. Additionally, protecting the skin from environmental exposures, such as excess sun exposure, smoking, and lack of sleep and exercise, can help maintain healthy collagen levels for healthy skin.
