Collagen plays a crucial role in the structure and strength of the skin, making it a vital component in maintaining skin integrity and elasticity. It is a protein that constitutes a significant part of the skin's dermal layer, providing support and ensuring the skin remains firm and resilient. As we age, collagen production decreases, which can lead to sagging skin and the appearance of wrinkles. Therefore, understanding collagen's primary function helps estheticians and skincare professionals develop effective treatments and recommendations to address skin aging and promote a healthy complexion.

Other functions, such as producing melanin or regulating moisture levels, do not pertain to collagen but rather to different proteins and substances, like melanocytes for melanin and various hydrating agents for moisture. Protection against UV rays involves other biological mechanisms, including the actions of antioxidants and specific skin cells, rather than the structural role of collagen. This distinction helps clarify why collagen is primarily associated with the structural and supportive aspects of skin health.
