Board‑certified dermatologist Dr. Jane Yoo presents a detailed review of four Biore UV sunscreen products she acquired while running the Tokyo Marathon. She explains the brand’s focus on texture innovation through proprietary technologies such as Aqua Capsule hydrogel encapsulation, humidity‑adaptive film, and Tough Boost Tech. For each product – Aqua Rich Watery Hold Cream, Aqua Rich Aqua Highlight Lotion, Aqua Rich Airy Hold Cream, and Athlizm Protect Mist – she outlines the filter systems (titanium dioxide, octinoxate, Uvinul T150, Uvinul A+, Tinosorb S, Mexoryl XL), additional skin‑care actives (hyaluronic acid, royal jelly, vitamin C derivative), performance claims (water/sweat resistance, low white cast, non‑comedogenic, alcohol‑free), and usage scenarios (daily wear, makeup primer, high‑intensity activity). Dr. Yoo highlights that many of these next‑generation filters are not yet approved for U.S. sunscreens, underscoring the regulatory gap and future market potential. Throughout, she emphasizes how the innovative textures improve user compliance and overall UV protection.

Hi everyone, I'm Dr. Jane Yoo, board-certified dermatologist and Mohs surgeon. While I was in Japan running the Tokyo Marathon, I had the chance to pick up some Biore UV products. As someone who is always on the lookout for next-generation UV filters that are not yet available in US sunscreens, this was a great opportunity. Biore UV is a sunscreen line from Japanese consumer goods giant Kao Corporation. What makes them particularly interesting from a formulation standpoint is their investment in texture innovation. These are very effective sunscreens that generally are pleasant to wear, which matters a lot for daily compliance. Let's start with the Aqua Rich line, Biore's UV flagship series, which centers on lightweight, water-based formulations built around Kao's proprietary Aqua Capsule technology. This technology encapsulates UV filters in a hydrogel that disperses evenly on the skin for a fresh, non-greasy feel. The Biore UV Aqua Rich Watery Hold Cream SPF 50 PA+++ is the first mineral UV absorber-free sunscreen in the Aqua Rich lineup, a significant milestone for the series. It uses titanium dioxide as its sole active ingredient, providing protection primarily against UVB and shortwave UVA. The titanium dioxide is dispersed within Kao's proprietary agar hydrogel capsules, which help deliver a light, even application that avoids the chalkiness often associated with mineral formulas. What makes this sunscreen especially innovative is its humidity adaptive film. Embedded water-retaining polymers respond to changes in the environment, by absorbing excess moisture in humid conditions to prevent that sticky feeling and releasing it in drier conditions to keep the skin from feeling tight or dry. In real-world testing, this technology led users to apply up to 1.5 times more sunscreen than with standard formulas, meaning better UV protection throughout the day. The result is a cream that feels moist and comfortable from morning to night, absorbs quickly, leaves limited white cast, and works well as a makeup base. It's also alcohol-free, paraben-free, colorant-free, and non-comedogenic tested, making it a thoughtful choice for those with sensitive skin or anyone who prefers to avoid chemical UV filters entirely. The Bioré UV Aqua Rich Aqua Highlight Lotion SPF 50+ PA++ takes a different approach and leans into a tone-up and primer effect. It contains pearl powder for a luminous pore-blurring finish and is infused with actives including hyaluronic acid and royal jelly extract for hydration. On the filter side, it uses octinoxate and titanium dioxide alongside Uvinul T150 for UVB, Uvinul A+ for UVA, Tinosorb S for both UVA and UVB. These last three are next-generation filters that are not yet approved for use in US sunscreens. It is strongly water and sweat resistant and makes for a quick no-makeup makeup look on its own. Now for something also innovative, the Bioré UV Aqua Rich Airy Hold Cream SPF 50+ PA++++. This product stands out again because of the humidity adaptive film technology in which UV filters are in agar hydrogel capsules combined with high water retention polymers. In hot, humid conditions, those polymers absorb excess moisture so the sunscreen film does not feel sticky or heavy. In dry, air-conditioned environments, they release that moisture back out to help keep the skin from drying out. The result is a texture that responds to your environment throughout the day and feels genuinely different from most sunscreens on the market. Its filter system includes octinoxate and titanium dioxide alongside next-generation filters Uvinul T150, Uvinul A Plus, and Tinosorb S. It is water-resistant, colorant-free, non-comedogenic tested, and contains hyaluronic acid and a vitamin C derivative for added skincare support. For those who need something built for intense activity, Beora UV also has an Athlizm line, which is engineered specifically for heat, sweat, and friction resistance. The Biore UV Athlizm Protect Mist SPF 50+ PA++++ uses what the brand calls Tough Boost Tech to maintain its UV protective film even under extreme conditions. The filter system includes octinoxate and Uvinul T150 for UVB, Uvinul A+ for UVA, Tinosorb S, and Mexoryl XL for broad UVA and UVB coverage, several of these next-generation filters that are not yet available in the US-approved sunscreens. The mist format is also non-aerosol and can be used on wet skin, hair, as well as the scalp. And you can press the nozzle fully for wide body coverage or halfway for a more targeted application. It rinses off easily with soap and water, making it practical and high performing. Biore UV is a great example of how Japanese sunscreen innovation continues to push what is possible in terms of both protection and wearability. As more of these next generation filters move towards approval in other markets, we may eventually see formulas like these become more widely available.
