What is the difference between UVA and UVB rays?

UVA and UVB rays are two types of ultraviolet (UV) radiation from the sun that affect our skin differently. UVA rays penetrate the skin more deeply and are primarily responsible for premature skin aging and wrinkles. In contrast, UVB rays are responsible for causing sunburn and play a key role in developing skin cancer.

Key points:

• UVA rays can penetrate deep into the skin layers.
• UVB rays primarily affect the surface of the skin.
• Both types of rays contribute to skin damage.
• Sun protection is essential for both UVA and UVB exposure.
