KAO BIORE UV Aqua Rich Smooth Watery Gel SPF50 + /PA ++++ 90ml – Made in Japan

Ultraviolet rays in sunlight can lead to long-term skin damages such as dark spots, freckles, dryness, wrinkles, and even skin cancer. Daily sunscreens protect the skin from those damages by shielding the skin from UV. In a Kao survey of women sunscreen users conducted in 2016, more than 90 percent of the survey respondents replied that they had experienced sunburn symptoms even when wearing sunscreen. This can occur when sunscreen is applied too little or not evenly. Sweat, water and rubbing may also chafe the sunscreen away. In observations using a UV microscope especially developed in the Kao laboratories, researchers have shown that*3 conventional water-base sunscreens (Kao products) sometimes disperse unevenly over the skin. With uneven application, micron-scale crevices may visibly appear when the sunscreen is spread on the skin. Kao’s water-based sunscreens, a range of products widely loved for their fresh textures, do not volatilize their oil phase including the UV protection ingredients, but plenty of the aqueous phase. This can result in the formation of crevices on the skin. When using a water-soluble UV protection agent in the aqueous phase, the UV protection effect likely comes off with perspiration and sebum on account of it being soluble in water.
