How can exposure to UV lasers affect the skin?

Exposure to UV lasers can be particularly harmful to the skin due to the nature of ultraviolet radiation. When the skin is exposed to UV lasers, it can suffer from burns similar to those caused by the sun. This effect is due to the energy from the laser penetrating the skin and damaging its cellular structure. The consequence of this damage goes beyond immediate burns; prolonged or repeated exposure can lead to an increased risk of skin cancer. This occurs because UV radiation can cause mutations in the DNA of skin cells, disrupting normal cellular function and potentially leading to malignant transformations.

The choice indicating no significant effect does not acknowledge the well-documented harms that UV radiation can inflict on the skin. Similarly, the notion that exposure may only temporarily affect skin color overlooks the potential for serious and lasting damage, which is a crucial aspect of laser safety training. While lasers may serve important purposes in various applications, understanding the risks associated with UV exposure is vital for ensuring safety and protecting skin health.
