Detailed answer

Sun exposure can increase the risk of hyperpigmentation, discoloration, and delayed healing of a scar. The ultraviolet (UV) rays from the sun can cause the scar tissue to become darker and more noticeable. It is recommended to protect the healing scar from the sun by keeping it covered with clothing or using a broad-spectrum sunscreen with at least SPF 30. It is best to avoid direct sun exposure during the peak hours of sunlight, typically between 10 am and 4 pm. Additionally, using products with ingredients like vitamin E, aloe vera, or silicone gel can help in the healing process and reduce the appearance of scars.
