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
