Types of UV rays and their effects
Ultraviolet A (UVA)
Ultraviolet rays account for about 90% of the total ultraviolet rays 
that reach the surface of the earth. This ultraviolet light reaches not 
only the epidermis but also the dermis at the back of the skin, 
causing dark pigmentation and causing spots and wrinkles. Since 
symptoms such as redness and inflammation are unlikely to occur, it 
is easy to get daily "inadvertent sunburn".
Ultraviolet B (UVB)
Ultraviolet rays that reach the surface of the earth only slightly, and 
have a dose of about 10/1 of ultraviolet rays. However, be careful 
because it has very strong energy. It can also cause sunburn and 
skin cancer. Since it has a strong effect on the skin, it is easy to get 
leisure sunburn" in the sea or sports.
Effects of ultraviolet rays
Ultraviolet rays are also said to make people old and cause various disorders to the body.
A long time ago, it was healthier and cooler to burn your skin and make it black! There was a 
time when it was said, but in reality, it was a heavy burden on the skin.
An example of the symptoms that ultraviolet rays give to the body
Spots
When exposed to a lot of ultraviolet rays, the genes of the pigment cells that make melanin in 
the skin are mutated and excessive melanin is made, causing many spots on the skin.
Wrinkle
Wrinkles are formed on the skin because it produces enzymes such as collagen and elastin that 
cut the fibers related to elasticity and elasticity into small pieces.
Damage to hair
When exposed to ultraviolet rays, the melanin of the hair is mutated, the color 
of the hair becomes brown, the cuticle is damaged, and the hair becomes dry.
Cataract
It passes through the cornea in the eyeball and damages the crystalline lens, 
resulting in cataracts.
Immune weakness
Ultraviolet rays destroy the cells responsible for the immunity of the skin, 
making it easier to get infected with bacteria and viruses and making it easier 
to get sick.
Skin cancer
When ultraviolet rays are absorbed by skin cells, they damage genes and cause 
skin cancer.
What are "SPF" and "PA"?
Sunscreens are mainly composed of UV absorbers 
and UV scatterers.
Ultraviolet absorbers can absorb ultraviolet rays, 
and convert the absorbed ultraviolet rays into heat 
energy and release it to the outside. In addition, 
UV scatterers have the power to repel UV rays so 
that they do not hit the skin directly.
There are various types of sunscreens, from infants 
to men and women, but you need to purchase 
them according to your needs. Therefore, the 
values “SPF "and " PA " can be used as a guide.
