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

enzymes such as collagen and elastin that cut the
fibers related to elasticity and elasticity into

the hair becomes brown, the cuticle is damaged,

responsible for the immunity of the skin, making

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
