What is the primary cause of skin aging?

The primary cause of skin aging is the degeneration of elastin and collagen. These two proteins are crucial for maintaining the skin's structure, elasticity, and firmness. As we age, the production of collagen and elastin decreases, which results in a loss of skin elasticity and the appearance of wrinkles and sagging.

While excessive sun exposure, poor diet, and dehydration can certainly contribute to the aging process or exacerbate existing signs of aging, the fundamental biological change that occurs over time, and leads to aging, is the natural deterioration of collagen and elastin fibers. This intrinsic aging is a significant factor that underpins other external or lifestyle-related influences. Maintaining the integrity of these proteins is essential for youthful-looking skin, which is why interventions often focus on stimulating collagen production and preserving elastin to combat aging signs effectively.
