The global skin care market will potentially reach $179 billion by 2022 with a CAGR of 4.7% from 2016 to 2022. This increase has been attributed to a rise in skin care awareness. The Asia-Pacific region currently leads the global skin care market and is estimated to remain the leader throughout the forecast period.

However, according to a Global Cosmetic Industry report, the fastest-growing sub-segment may be in sun protection. Preeti Bisht, research analyst for Allied Market Research, stated in the report, "Anti-aging and sun protection segments fuel the Asia-Pacific market due to the increase in aging population, compared with developed countries."

Shiseido, being an old bard to the industry, is well aware of this potential. And a new patent application shows the company is cooking up something new in sun protection.
