Can sunscreen protect against all types of UV rays?
Short answer: Yes, sunscreen can protect against all types of UV rays.
Detailed answer
Sunscreen is designed to protect the skin from both UVA and UVB rays, which are the two main types of ultraviolet radiation. UVA rays are responsible for premature aging and can penetrate deeper into the skin, while UVB rays are the primary cause of sunburn. A broad-spectrum sunscreen with a high SPF (Sun Protection Factor) can provide protection against both UVA and UVB rays. It is important to choose a sunscreen that offers broad-spectrum protection and reapply it every 2 hours, especially when exposed to direct sunlight or engaging in outdoor activities. It is also important to note that sunscreen should be used in conjunction with other sun protection measures, such as seeking shade, wearing protective clothing, and using sunglasses to further minimize UV exposure.
