The sun’s rays are responsible for approximately 80 to 85 percent of skin aging, which is primarily attributed to UV radiation. This exposure can lead to photo-aging, a process that causes skin changes such as wrinkles, fine lines, age spots, and a loss of elasticity. UV radiation has both immediate and long-term effects on the skin, leading to the breakdown of collagen and elastin fibers, which are crucial for maintaining skin structure and firmness.

Genetic factors play a role in the aging process but are not as significant in skin aging as solar exposure. While diet and nutrition contribute to overall health, their impact on skin aging is less pronounced compared to the effects of UV light. Similarly, environmental pollutants can contribute to skin damage but account for a smaller percentage of the aging process compared to the influence of sunlight. Understanding the dominance of sun exposure in aging emphasizes the importance of sun protection as part of a comprehensive skincare routine.
