    Your skin happens to be one of the most sensitive external organs. This 
makes it susceptible to damage caused by the harmful UV radiation 
from the sun. Whether you love spending quality time on the beach or 
work outdoors for prolonged hours, it’s imperative to secure your skin 
from harmful solar radiation. Even 15 minutes of sun exposure can 
adversely affect your skin.
    In this post, we will explore the impact of different types of UV rays on 
the skin. This includes UVA, UVB, and UVC. UV radiation is a form of 
electromagnetic radiation of solar energy. Let’s check out each type of 
UV radiation and know what type of damage they tend to do to our 
skin.
UVA rays
    UVA accounts for 95% of the solar radiation that reaches us from space. 
The wavelengths are higher, and the energy level of UVA is lower as 
compared to other UV radiations. However, the penetrative power of 
UVA is higher than that of UVB. This implies that they tend to affect your 
skin more adversely and deeper. This way, they inflict indirect damage to 
your DNA.
    Exposure to UVA might result in premature aging of your skin. You might 
notice wrinkles on your skin, and prolonged exposure can lead to skin 
cancer. The ozone layer doesn’t absorb UVA, and the radiation can cause 
immediate tanning.
UVB rays
    Unlike UVA, UVB often gets absorbed or filtered by the ozone layer. 
However, the depleting ozone layer is a worrying element, that exposes 
you to these harmful radiations. The wavelength of this radiation is 
shorter, and they carry higher energy levels. They inflict direct damage 
to your DNA, affecting the outer layers of your skin.
    Most types of skin cancer are caused by UVB exposure. Besides, they 
cause the skin to wrinkle. Overexposure to these rays can cause 
sunburns. However, these rays cannot penetrate windows. In most 
cases, the cloud and the ozone layer filter these rays.
UVC rays
    Among the three types of UV radiations, UVC is the shortest 
wavelength. This defines its damage potential, as they are more direct. 
However, the good news is that UVC cannot get through the 
atmosphere of the earth. Although it is the most dangerous radiation, it 
doesn’t pose a direct threat to your skin. The ozone layer absorbs most 
of the UBC rays.
    However, you cannot possibly overlook some inorganic sources of these 
rays. Improper handling can cause skin damage due to exposure. For 
instance, mercury lamps, welding torches, and germicidal UV-C lighting 
can damage your skin with this type of radiation.
Protecting yourself from harmful UV exposure
    Using a broad-spectrum sunscreen happens to be the best solution for 
protecting yourself from the adverse impact of UV rays. Depending on 
your skin type and level of exposure, you can choose a sunscreen with 
an SPF level ranging between 15 and 50, or even higher.
    UVA and UVB are two of the most adverse types of solar radiation 
affecting your skin. Therefore, it makes sense to protect your skin when 
you remain outdoors. Get a quality sunscreen lotion or cream to protect 
your skin. This way, you can prevent premature aging, skin cancer, and 
other types of skin damage.
