This non-chemical sunscreen uses only zinc oxide as a UV scattering agent, making it recommended for sensitive skin. It does not contain titanium dioxide, which has a strong photocatalytic effect. Although it uses UV scattering agents, which tend to cause a white cast, it utilizes oils with high pigment dispersibility, resulting in beautiful dispersion and minimizing issues like white cast, streaking, and unevenness. It is expected to be waterproof and have high skin adherence. Because it uses a lot of rich-feeling oils, it effectively locks in and protects the skin's internal moisture. It also helps prevent makeup from smudging. Cell Fusion C Sunscreen Korean Cosmetics Used about 4 times. Thank you.
