UV and UVB are types of ultraviolet radiation, a form of electromagnetic radiation that comes from the sun. Ultraviolet radiation is invisible to the human eye, but it can have significant effects on our skin and health.
- UVA (Ultraviolet A) has a longer wavelength and is primarily associated with tanning and skin aging. However, it can also contribute to sunburn.
- UVB (Ultraviolet B) has a shorter wavelength and is mainly responsible for causing sunburn. UVB rays are also linked to skin cancer.
While both UVA and UVB can damage the skin, UVA rays penetrate deeper into the skin than UVB rays. This means that UVA can contribute to long-term skin damage, such as wrinkles and age spots, even if you don't get sunburned.
It's important to protect yourself from both UVA and UVB rays by wearing sunscreen, protective clothing, and seeking shade during peak sun hours.
