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, <TYPE I> has the highest risk of damage, and <TYPE VI> has the lowest risk.

Since it has a certain degree of melanin protection, the risk of UV damage is smaller than that of <TYPE I>, 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.

“PA” to prevent UVA

“PA” is a measure of the effect of preventing UVA (ultraviolet A wave), which causes temporary blackening and causes the skin to lose its elasticity over a long period.
