UVA vs UVB: What’s the Difference?

Summer, the warmest season of the year, is just around the corner. It’s the time of the year when people go on a vacation and expose to summer sunshine more often. Do you know that in the summertime, prolong exposure to the sun could potentially harm the skin? In fact, according to research, more than 90% of the appropriate count of UV rays can cause different kinds of skin ailments. Thus, it is a must that people will take extra protection against the harmful UV rays such as caps, umbrellas, and sunblock.

Unknown to many, UV rays are categorized according to their wavelength. In terms of skin penetration, the shorter the wavelength, the less it will penetrate the skin. However, it also means that the shorter the wavelength, the more harmful the UV radiation.

Ultraviolet A (UVA)

UVA is a kind of UV radiation can penetrate the skin’s thickest layer called dermis. If you are familiar with skin tanning, this radiation is responsible for that effect. Also, this radiation can cause skin wrinkles.

Ultraviolet B (UVB)

Another type of UV radiation is UVB. This kind of UV radiation can only penetrate the epidermis. While this radiation enhances skin aging, it can also help in the development of skin cancer.
