It spreads easily, doesn't feel like sunscreen, and doesn't squeak at all. I was worried that it might get messy if my skin felt a little dry, but as long as I moisturized my skin thoroughly before using it, it wasn't a problem!
The texture is a light, moisturizing emulsion. It blends smoothly into the skin and is completely free of the heavy feeling that is typical of sunscreens, making it feel like you're wearing a lotion. Formulated with hyaluronic acid and Centella asiatica (cica), it's moisturizing without being sticky. It's non-drying, so it feels like your skin's barrier is protected, which is a nice bonus. It can also be used as a makeup base, so it saves time in the morning. It also makes foundation go on better! It keeps your skin translucent and doesn't look white even when you're out in strong UV rays. However, it is a little sensitive to sweat and sebum, so we recommend reapplying it frequently.
I was looking for something light and easy to use on days when I'm not wearing makeup, and I finally found this. It's a push-type product, so you can adjust the amount and avoid using too much, which is convenient. It's a very refreshing gel-like product that spreads easily. It doesn't have the gritty feeling of sunscreen, so you can use it like a skincare product. It doesn't leave a white cast. It's packed with moisture, so it's hydrating and doesn't dry out, making it easy to use and gentle on the skin. And with SPF50+ PA++++, you can expect solid UV protection! However, I was a little disappointed that it left a flaky mess after application, depending on the skincare I use. It's also reasonably priced, so I think I'll use it as a secondary product, depending on the skincare product I use.

Even though I have sensitive skin, it didn't sting. It also doesn't leave a white cast, and it's just the right amount of watery, so it spreads smoothly. I'm very happy with it because it doesn't have the typical smell of the sunscreen I used a while ago. I also like how it's hygienic to use by pushing it, and you don't get too much. It feels a little pricey, but I'd like to use it again when I run out.
