Detailed answer

Sunscreen protects the skin by acting as a barrier against damaging ultraviolet (UV) radiation from the sun. It contains active ingredients that work in different ways to shield the skin. Sunscreen absorbs UV rays, converting their energy into a less harmful form, such as heat. It also reflects and scatters UV rays away from the skin's surface, preventing them from penetrating the deeper layers. This helps to minimize the harmful effects of UV radiation, including sunburn, premature aging, and an increased risk of skin cancer. To ensure optimal protection, it is important to apply sunscreen generously and reapply it regularly, especially after swimming or sweating.
