The foundation of smooth, youthful skin lies in a healthy network of collagen and elastin fibers within the dermis. In optimal conditions, your body continuously produces new collagen to replace aging fibers, maintaining skin structure and resilience. However, starting as early as your mid-20s, collagen production declines by approximately 1% per year, and this decline accelerates significantly after menopause or with chronic sun exposure.
This progressive loss of structural support creates visible creases and folds, resulting in the forehead lines, crow's feet, and frown lines characteristic of aging skin. When collagen fibers fragment and elastin loses its ability to snap back, the skin's natural scaffolding becomes insufficient to maintain a smooth surface.
Your skin's moisture barrier also plays a critical role. When this barrier becomes compromised through environmental damage or hormonal changes, transepidermal water loss increases dramatically, leaving skin thinner and more prone to the fine lines many patients notice first around the eyes and mouth.
