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

Really good spf
Size: 2.5 Fl Oz (Pack of 1)
I’ve been using this for a little while now and I actually really like it. It feels nice on the skin, doesn’t feel heavy, and leaves my face looking fresh and smooth. I also noticed my skin feels softer after using it consistently. Definitely something I would buy again.

Pretty lightweight
Size: 2.5 Fl Oz (Pack of 1)
Although it still leaves a little bit of a shine ( more of a dewy look), there is definitely not that much of a greasy feel which really helps me to keep being consistent with using sunscreen because my big issue with using other sunscreens is that they're too greasy feeling and not lightweight and leave too much of a shine on my already oily face.
