Excellent for the face! Many sunscreens claim they are good for the face, and blend well. This one actually DOES!! It is also an excellent moisturizer under your makeup without streaking. Just a smooth, beautiful finish. I wear it all year around The sun is just as strong and quite capable of ruining your skin in the winter as well.

Not amazing, but not the worst.

I hate sunscreen and to varying degrees chemical or mineral sunscreens. This was promised as grease free and smooth, but it comes out watery and does feel greasy, but once applied on the skin it does feel smooth. UPDATE: I got a suntan after slathering this on my face. I would say this lasts about an hour and a half. The suntan happened 15 minutes before the two hour "clock" was up. Disappointing. Back to mineral sunscreen.

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.
