    Glossary Skin Firmness

    ability of skin to resist deformation and maintain shape

    Skin firmness refers to the skin's ability to resist deformation and maintain its shape. It is largely determined by the presence and quality of collagen and elastin fibers in the dermis, which provide structural support and elasticity. As we age, the production of these proteins decreases, leading to sagging and less firm skin.
