This stuff is magic!
Size: 1.7 Fl Oz (Pack of 1)
I farm and garden. I spend hours outdoors in the summer, and for years, I’ve hated wearing sunscreen because it made my face feel hot and sticky. This sunscreen is none of that. I received a small sample tube of it from the dermatologist and instantly fell in love with it. It goes on smooth and covers well. But the thing I love about it is that I don’t feel like I’m wearing sunscreen once it absorbs into my skin. I forget about it! It doesn’t combine with my sweat and run into my eyes, making them sting. It doesn’t irritate sensitive skin or clog my pores. This stuff is magic and I will be using it daily. It’s not the least expensive sunscreen out there, but it’s worth it!

Terrible white cast
Size: 1.7 Fl Oz (Pack of 1)
You will look like you just got blasted by Jack Frost in the middle of the summer. This sunscreen could double as a hair identifier from the way it clings to each strand, leaving an incredibly noticeable white residue. I am very fair and on my skin itself the white cast is much less obvious/fades, my eyebrows on the other hand? Frostbitten. Snow swept. Bringing to mind polar bears and penguins. It's an alright sunscreen. Does the job. Does not look good while doing it.

Great Product

Most importantly, this stuff works! And I absolutely love that it’s not greasy. My face isn’t shiny or slick when i apply it. I’ve had no issues with my skin tolerating this sunscreen.

Perfect Sunscreen for Acne-Prone Skin! ☀️✨
Size: 2.5 Fl Oz (Pack of 1)
I absolutely love this sunscreen! Eucerin has honestly become one of my favorite skincare brands because this is one of the only sunscreens that works well with my acne-prone skin. It doesn’t feel heavy or greasy, doesn’t clog my pores, and most importantly, it doesn’t break me out. The finish feels lightweight and comfortable for everyday wear. The only small downside is that if it gets into your eyes, it can burn a little, so I try to avoid applying it too close to the eye area. Other than that, it’s amazing and I will definitely keep repurchasing it
