The risk of UV damage is reduced if you choose
according to the sunburn type Even if you go to
the sea together, people who turn red and then
turn black, people who turn red and then quickly
return to normal, people who turn black
immediately, and so on, the type of sunburn
varies from person to person. Why is that? The
figure above is classified into 6 types based on
the skin reaction (prone to red and black) after
sunbathing for 30 to 45 minutes from spring to
summer. Since melanin acts to block UV rays,
ltTYPE Igt has the highest risk of damage, and
ltTYPE VIgt has the lowest risk. Since it has a
certain degree of melanin protection, the risk of
UV damage is smaller than that of ltTYPE Igt, which
is common in Westerners, but since melanin
production is active, problems such as
pigmentation such as stains due to UV rays are
more likely to occur. Especially for ltTYPE IIIgt
and ltTYPE IVgt people, it is necessary to pay
attention to the UVA block that blackens the skin
in a short time. The symptoms of sunburn and how
to deal with it vary depending on the skin type.
If you know your skin type, you can take measures
against UV rays and aftercare that suit your
skin, so it will be easier to keep your ideal
skin tone.

effect of preventing UVA (ultraviolet A wave),
which causes temporary blackening and causes the
