• Types of UV radiation: UVA, UVB, and UVC

UVA rays are the most abundant and can penetrate deep into the skin, causing premature aging and contributing to skin cancer. UVB rays are responsible for sunburn and also play a significant role in skin cancer development. UVC rays are the most dangerous but are mostly absorbed by the ozone layer and do not reach the Earth's surface. Understanding the different types of UV radiation is crucial for choosing the right sun protection.
