Can wrinkles or fine lines eventually heal on their own if you spend too much time in the sun?

Wrinkles and fine lines caused by sun exposure cannot heal on their own. Once the skin has been damaged by UV radiation from the sun, the damage is permanent and cannot be reversed naturally. Wrinkles and fine lines can be improved with proper skincare, including daily use of sunscreen, moisturizing, and avoiding further sun exposure, but they will not disappear completely. For significant changes or deeper wrinkles, cosmetic procedures such as laser resurfacing, chemical peels, or dermal fillers may be considered to reduce their appearance.
