It's moisturizing and easy to use
The texture was also good!
It not only blocks UV rays, but also blue light, near-infrared rays, and air pollution. This "undiluted UV serum" contains the perfect ratio of fullerene, vitamin C derivative, and ceramide, making it the perfect finishing touch to your morning skincare routine. Another great thing about it is that it's waterproof but can be removed with soap! Living in the Shonan area, the sun is extremely strong, so this has become a very reliable UV protection tool, especially for my husband, who enjoys surfing. It's mine, but he keeps taking it! lol
It's amazing that it's a beauty serum that also has sunscreen properties. It's not sticky, which is great.
The description "it's like a moisturizing cream" is perfect. It has none of the unpleasant feeling that is common with sunscreens, and is very comfortable to apply. It does leave a glossy finish, so those who don't like glossy finishes may find it bothersome. I'm concerned about the oxidation of sebum during the day, so I'm using it hoping that the fullerenes and vitamin C will help prevent this. The pump type makes it easy to use, which is great. I'm considering repurchasing.
