There is now worldwide awareness of the chronic and acute damage to human

skin caused by the ultraviolet (UV) rays in sunlight. Nevertheless, people of

different nationalities have differing skin responses, differing concerns about

the consequences of exposure, and differing attitudes to suntan and sunburn.

Surveys show that Japanese women are most anxious about pigmentation, so

their prime expectation of sunscreen products is to prevent skin pigmentation.

Pigmentation is caused by not only UV-B but also UV-A, so sunscreen products

for the Japanese market should have both UV-B and UV-A protective potencies.
