What is considered the main external damage to the skin?

Sun damage is recognized as the main external damage to the skin due to its pervasive and harmful effects on the skin’s health. Ultraviolet (UV) rays from the sun are the leading cause of skin aging, sunburn, and skin cancers, including melanoma. This type of damage can lead to a breakdown of collagen and elastin in the skin, resulting in wrinkles and loss of elasticity.

While factors like pollution, harsh weather conditions, and improper skincare certainly contribute to skin issues, they typically do not possess the same level of direct and damaging impact that prolonged exposure to the sun has. The cumulative nature of sun exposure, especially without adequate protection, underscores its primary role in skin damage over time, making it a critical factor for individuals to consider in their skincare routines.
