Experience the next generation of fluid photoprotection with the Kao Biore UV Aqua Rich Aqua Protect Lotion SPF 50+ PA++++. Specially calibrated to eliminate the heaviness, chalkiness, and oiliness of conventional high-protection sunscreens, this water-burst liquid sunscreen lotion utilizes advanced phase-shifting technology to encapsulate broad-spectrum UV filters within light water droplets. Upon skin contact, the lotion breaks into a weightless fluid that glides effortlessly across micro-contours before sealing into a second-skin UV shield. Enhanced with deeply nourishing botanical extracts and humectants, this Japanese formulation guards skin against photo-induced collagen breakdown, solar hyperpigmentation, and dehydration while remaining completely invisible.

Water-Capsule Rheology & Advanced Photoprotective Membrane Mechanics

Phase-Shifting Liquid Matrix & Dermal Adhesion

The core innovation of the Aqua Protect Lotion lies in its micro-emulsion rheology. Suspended within an aqueous base are lipid-soluble UV filters encapsulated inside micro-droplets. When spread across the stratum corneum, the mechanical shearing force disrupts the outer water shell, instantly releasing a splash of hydrating liquid. As the volatile water phase dissipates, the organic UV filters fuse together to create a continuous, ultra-thin, smooth-fit membrane that adheres tightly to the skin's surface without settling into fine lines or pores.

Synergistic Organic Filter Shield & Hydration Preservation

To offer full-spectrum defense, the formulation integrates a stable matrix of organic UV filters—including Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus), Ethylhexyl Triazone (Uvinul T 150), and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S). This high-performance network absorbs both sunburn-causing UVB rays and deep-penetrating UVA rays responsible for structural photo-aging. To offset solar-induced hydration depletion, Sodium Hyaluronate and Royal Jelly Extract continuously bind water within the upper epidermal layers, ensuring the skin remains plump and balanced throughout the day.

Seamless Daily Wear & Cosmetic Compatibility

Engineered for daily use under humid or hot environmental conditions, the lotion features an ultra-fluid texture that shakes up easily and applies without friction. It leaves zero white cast across all fitzpatrick skin tones and sets into a smooth, supple canvas that enhances the wear time of liquid foundations and concealer formulations.

Skin Type Suitable for all skin types, particularly normal, combination, oily, and dehydrated skin profiles seeking high UV defense with a weightless, water-like texture.

Concerns Solved UVA/UVB-induced photo-aging, solar hyperpigmentation/sun spots, heavy/greasy sunscreen residue, white cast, sunscreen pilling under makeup, and solar dehydration.

Texture A ultra-thin, milky liquid that breaks into a wet, watery film upon application, drying down rapidly to a clear, weightless, natural-skin finish.

Usage Time Designed for daily morning (AM) use as the final step in the skincare routine prior to makeup application.

Compatible Routines Integrates perfectly into any AM skincare routine after serums and light moisturizers. Functions seamlessly as a hydrating, smoothing primer before liquid or powder cosmetics.

Who Should Avoid It

• Alcohol-Sensitive Profiles: Formulated with Ethanol to achieve its signature rapid phase-shifting and weightless dry-down; individuals with hyper-reactive barrier breakdown due to topical denatured alcohol should perform a targeted patch test.
