It penetrates to the dermis, damaging collagen and elastic fibers, leading to wrinkles, loss of elasticity, and leathery texture. This energy is high enough to directly damage the DNA in skin cells, making it the primary culprit for sunburn and the immediate tanning response.
Three Types UV Radiation Protection Tips
UV-C: The Germicidal Range Absorption and Artificial Generation Short-wave ultraviolet C (UV-C) encompasses wavelengths from 100 to 280 nanometers and possesses the highest energy of the three types. Effects on Skin and Health While UV-A is not the primary cause of sunburn, it plays a critical role in long-term skin damage and photoaging.
Importantly, UV-A generates reactive oxygen species that indirectly harm DNA, contributing to the cumulative risk of skin cancer, including melanoma, over years of exposure. This radiation is almost entirely blocked by the Earth’s atmosphere and the ozone layer, meaning natural UV-C from the sun never reaches human skin.

Applications and Safety Due to its powerful ability to destroy the nucleic acids of microorganisms, UV-C is a cornerstone of sterilization and disinfection technology. UV-B photons carry higher energy than UV-A, primarily affecting the outer layers of the skin—the epidermis.
