Skin Laxity is the process when the skin loses its natural elasticity. During this process, the skin loses collagen and elastin, which are the skin’s main structural protein components.
What is Elastin?
Elastin is an extracellular matrix protein that produces elasticity and resilience to the body. It’s a stretchy protein that acts like a rubber band – it can stretch out (extend) and shrink back (recoil). It is found in the dermis layer of the skin, lungs, blood vessels and other body parts that require elasticity.
What is Collagen?
Unlike Elastin, Collagen is a protein that helps the skin cells stay strong and resilient. It is mainly made of amino acids glycine, proline, and hydroxyproline. It forms a framework that provides strength and structure within the body. It is an essential component of the connective tissue and is in charge of holding the body’s cells together. Additionally, it provides strength and elasticity to the skin.
Factors that may contribute to loss of Collagen and Elastin
Hormonal changes such as pregnancy, menopause, health conditions
Oxidative stress, which results from metabolic processes and lifestyle choices, such as smoking and diet
Low levels of vitamin C, which can lead to scurvy
