Great product makes my skin look dewy and soft with no powdery biproduct
Size: 3 Fl Oz (Pack of 1)
Excellent product. It looks white on my fingertips but absorbs as a clear product which feels soft, cool, and gel-like on my skin. I usually use it with a gel moisturizer but I think one can use it on its own.

Sunscreen for Combination and Sensitive Skin
Size: 3 Fl Oz (Pack of 1), Size: 3 Fl Oz (Pack of 1)
I’ve been buying different skincare products because I really want to improve the way my skin looks and feels. My skin type is combination, with a history of acne, some acne marks, enlarged pores (especially on my nose and cheeks), a dull and slightly dry tone, occasional sensitivity, a light expression line on my forehead, and sometimes dry patches. As you can see, I have quite a few concerns, so I have to be careful with the products I use.
💬 I chose this Sunscreen, and I’ve absolutely loved it! The texture is lightweight and keeps my skin well-hydrated throughout the day. My face doesn’t look dull anymore — it looks fresh and naturally glowy, which I really appreciate. I also love how quickly it absorbs without leaving any greasy or sticky feeling. And of course, the most important part: it really protects my skin from the sun.

Great product but expensive and small
Size: 3 Fl Oz (Pack of 1)
This looks great on the skin, it's a very good product. Expensive for the size though, the tube is more like travel size. I think it's worth it if you have sensitive or acne-prone skin as this didn't break me out like traditional sunscreens, but I think it's expensive for how much you get.
