Terrible for normal/combo skin! I applied sunscreen to my clean, dry face – without moisturizer. After waiting 25 minutes, I checked to see if the product hadn’t absorbed into my skin. It remained on top of my skin in a shiny, slippery, greasy film that rubbed off onto anything it touched. It’s settled thickly into crevices and fine lines, especially in the folds of my eyelids. There was so much shine – not glow – on my skin that it created flashback when I took a picture. Somehow, the sunscreen made my skin appear both oily and dry at the same time! Many other reviewers said that they successfully put make up over this sunscreen, but I cannot imagine how this would be successful, unless the makeup finish was incredibly matte. It’s the worst experience I’ve ever had with any sunscreen!
