AMAZINGGGGG!!!!!!! Super light weight, no sunscreen smell, barely smells slightly like citrus , moisturizing, it’s just truly perfect like I can’t express enough and it’s most likely good on the Yuka app because it has super clean ingredients. Not sponsored just someone who searched high and low for a good quality sunscreen that’s not toxic. Seriously this sruff is amazing

Excellent

Size: 2.12 Ounce (Pack of 1)

So good I have re ordered for family. It goes on lite and gets clear almost immediately. Skin feels great with it on. Lightly moisturized and not greasy or sticky. Little to no scent.

Best I've tried in awhile

Size: 2.12 Ounce (Pack of 1)

I'm not allergic to it & didn't burn! Wasn't greasy, easy to apply. Worked great for face, neck, chest and arms. Wore for a week straight. Didn't clog pores or cause skin issues. Worked great as a sunscreen. Stayed solid enough in FL heat that TSA didn't confiscate. Double bonus

Great sunscreen

Size: 2.12 Ounce (Pack of 1)

This is the creamiest best sunscreen ever. It's not greasy and it feels like it's definitely moisturizing and goes on super smoothly.

Great all around sunscreen

Size: 2.12 Ounce (Pack of 1)

Love this product. I have dry skin and this is emollient but not greasy. Floats over my fave and feels just right while softening my fine lines. Light fragrance that’s not too much. I definitely recommend this for all skin types.
