Which factor can worsen actinic aging?

Sun exposure is a primary factor that can significantly worsen actinic aging, which refers to skin damage due to prolonged exposure to ultraviolet (UV) radiation, primarily from the sun. When the skin is exposed to UV rays, it undergoes a variety of changes, including the breakdown of collagen and elastin—proteins essential for maintaining skin's elasticity and firmness. This leads to wrinkles, sunspots, rough texture, and other signs of premature aging.

The damaging effects of UV radiation can also compromise the skin's barrier function, making it more susceptible to environmental stressors and further accelerating the aging process. Protective measures such as sunscreen application, wearing protective clothing, and seeking shade are essential in preventing actinic aging and maintaining the skin's health over time.

Other factors like genetics, hormonal changes, and dietary choices can influence skin health, but they do not have the same direct and damaging impact on skin aging as consistent sun exposure does. For instance, while genetics can dictate skin tone and sensitivity, and hormonal changes can influence moisture levels and skin elasticity, the cumulative effect of UV damage is significantly greater in the context of actinic aging.
