What is Collagen?

A structural protein making up 70–80% of the dermis, essential for skin firmness and elasticity

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.

Key properties & actions

Collagen is a structural protein that is known to account for approximately 70–80% of the dermis and to support the skin's elasticity and tensile strength. Type I and Type III collagen are the primary types found in skin, and research indicates that production begins declining by roughly 1% per year starting around age 25. UV exposure in particular is considered a major external factor in collagen degradation.

How to manage

Daily use of sunscreen may help slow collagen loss. Consistently using ingredients known to support the collagen synthesis environment — such as vitamin C and retinol — along with lifestyle habits like adequate sleep and sufficient protein intake, is advisable. If you feel that elasticity is declining rapidly, consulting a dermatologist is recommended.

Good to know alongside

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

Everyday care tips

Wearing a hat and sunglasses when outdoors can also help reduce photoaging. In practical terms, focusing on habits that support the skin's own collagen synthesis environment is generally more effective than relying on topical collagen alone.
