Sunscreen is a vital product that protects the skin from the sun's harmful UV rays. It is typically applied topically and works by absorbing or reflecting ultraviolet (UV) radiation.

Sunscreen is available in various forms, including:

• Lotions
• Creams
• Sprays
• Gels

These products come in different strengths, indicated by their SPF (sun protection factor) levels. The higher the SPF, the more protection the sunscreen provides against UVB radiation, which is the main cause of sunburn and skin cancer.

Applying sunscreen is essential for anyone spending time outdoors. It is recommended to:

• Apply it at least 15-30 minutes before sun exposure.
• Reapply every 2 hours, or after swimming or sweating.
