Detailed answer

Sunscreen application under the eyes is beneficial in preventing dark circles and under-eye bags as it helps protect the delicate skin in this area from the harmful effects of the sun. The skin under the eyes is thin and more prone to damage due to sun exposure. UV rays can cause the skin to produce more melanin, resulting in dark circles. Sun damage can also weaken collagen and elastin fibers, leading to under-eye bags. By applying sunscreen with a high SPF under the eyes, you can reduce the risk of these issues and maintain a more youthful appearance. Additionally, using a broad-spectrum sunscreen will protect against both UVA and UVB rays, which are responsible for various types of skin damage.
