There's no break from protecting yourself from UV rays.
Rohto Pharmaceutical Co., Ltd., as a pharmaceutical company, conducts various research related to human skin and lifestyle. We also keep up with the latest research findings and continuously pursue the ever-evolving advancements in science.
Meanwhile, as research into aging caused by ultraviolet radiation (photoaging) progresses, the importance of taking measures against ultraviolet radiation has become clear.
In particular, ultraviolet A rays (UVA) can penetrate clouds and window glass, so protection is essential even on cloudy days or when you are indoors.
While measures such as wearing hats, long-sleeved shirts, and sunglasses are effective, from a practical standpoint, using or combining sunscreen is extremely important.
Furthermore, UV protection isn't something you only need to do during the daytime when the summer sun is beating down.
Ultraviolet rays are constantly beating down from above, both in the morning and afternoon, in summer and in winter, so sun protection is essential throughout the year.
