Types I and III are predominantly found in skin, decreasing by about 1% annually after age 25. UV exposure is the primary cause of degradation.

Main causes & characteristics of Collagen

Collagen is a structural protein known to make up approximately 70–80% of the dermis, supporting the skin's elasticity and firmness. Type I and Type III collagen are the primary types found in skin, and research indicates that production begins to decline by approximately 1% per year starting around the mid-twenties. UV exposure in particular is frequently cited as a major external factor that degrades collagen.

Managing Collagen

Daily use of sunscreen may help slow the rate of collagen decline. Consistently incorporating ingredients known to be involved in the collagen synthesis environment — such as vitamin C and retinol — is advisable, along with supporting lifestyle habits such as adequate sleep and sufficient protein intake. If you feel that loss of elasticity is progressing rapidly, consulting a dermatologist is recommended.

Related information

Collagen is grouped with elastin and hyaluronic acid as key components of the dermis, and is often discussed alongside aging-related concepts such as photoaging and glycation.

Everyday care tips

Using a hat and sunglasses when going outside can help reduce photoaging alongside your skincare routine. Focusing on habits that support the skin's own collagen synthesis environment is generally more practical than relying on ingestible collagen supplements.
