Kao's New Bioré Sunscreen Reacts to the Weather on Your Skin
Japan's latest SPF launch uses humidity-responsive gel capsules that soak up sweat in the heat and release moisture in dry, air-conditioned air.
Kao launched the Bioré UV Aqua Rich Airy Hold Cream (SPF50+/PA++++) on March 8, 2025, using agar-gel 'aqua capsules' with a humidity-responsive agent that absorbs sweat in humid heat and releases moisture in dry or air-conditioned air, with a rollout planned across 27 countries and regions.
Kao Corporation describes the formula's humidity-responsive technology as a way to keep the sunscreen film comfortable as conditions shift, an approach that reflects why Japanese SPF is widely praised for its lightweight, adaptive feel.
Questions we get a lot
What makes the Bioré UV Aqua Rich Airy Hold Cream different?
According to Kao, the formula uses agar-gel aqua capsules paired with a humidity-responsive agent. In humid heat the film absorbs sweat, and in dry or air-conditioned air it releases moisture, aiming to stay comfortable as your environment changes. It carries an SPF50+/PA++++ rating, the highest tier in Japan's labeling system.
When and where did this sunscreen launch?
Kao launched the Bioré UV Aqua Rich Airy Hold Cream on March 8, 2025. The company's release describes a rollout across 27 countries and regions, signaling the brand's continued international expansion. Availability and timing can vary by market.
What does SPF50+/PA++++ mean?
SPF50+ indicates very high protection against UVB rays, the band primarily responsible for sunburn, while PA++++ is Japan's top rating for UVA protection. Kao lists the Airy Hold Cream at this combined rating, meaning broad, high-level coverage. The PA system, with one to four plus signs, is the standard used across Japan and much of Asia.
