## Answers.
1. SPF sunscreen stands for Sun Protection Factor sunscreen. It is a type of lotion, spray, or cream that is applied to the skin to protect it from the harmful effects of the sun's UV rays.
2. SPF sunscreen works by blocking or absorbing the UV rays that can damage the skin. The SPF number on the sunscreen bottle indicates how effective the product is at protecting the skin from the sun. For example, a sunscreen with SPF 30 will block or absorb about 97% of the UV rays, while a sunscreen with SPF 50 will block or absorb about 98% of the UV rays.
3. To effectively protect the skin from the sun, SPF sunscreen should be applied generously and evenly to all exposed areas of the skin at least 15-30 minutes before going outside. It should be reapplied every 2 hours, or more often if swimming or sweating. It is important to choose a broad-spectrum sunscreen that protects against both UVA and UVB rays for complete sun protection. Additionally, wearing protective clothing, seeking shade, and avoiding peak sun hours can further help protect the skin from sun damage.
