Detailed answer

Wearing sunscreen can be beneficial in protecting the under-eye area from dark circles. The skin around the eyes is delicate and prone to damage from sun exposure. Sunscreen works by forming a protective barrier on the skin, blocking harmful UV rays that can contribute to skin discoloration and dark circles. Additionally, sunscreen helps to prevent premature aging and photoaging, which can lead to the appearance of dark circles due to collagen and elastin breakdown. Applying a broad-spectrum sunscreen with at least SPF 30 under the eyes daily can aid in protecting this sensitive area and reducing the likelihood of dark circles.
