Is sun protection important for the recovery of dark scars?
Generally speaking, black scars refer to scars with melanin deposition. Sun protection plays a relatively important role in the recovery of scars with melanin deposition. The specific analysis is as follows:
Ultraviolet radiation is the main factor that stimulates melanocytes in the skin to produce melanin. When UV rays hit the skin, the skin goes into a self-protective state and releases melanin. This melanin darkens the skin tone, making the scar more noticeable. Therefore, sun protection is an important step in preventing scars from darkening.
Sun protection can prevent further irritation of the scar area by ultraviolet rays, avoiding excessive activation of melanocytes, thereby reducing melanin production and deposition. Sun protection also helps promote the scar repair process; when the scar area is protected and shielded from UV damage, skin cells can better perform repair and regeneration, thus accelerating the fading of scars.
During outdoor activities, applying sunscreen, wearing hats, using umbrellas, and wearing long-sleeved clothing can reduce direct UV exposure to the scar area.
