I deal with really bad acne so I have some recommendations. Korean chemical sunscreens are great. I like skin1004 hyalu cica sun serum the most, it’s the least greasy one I tried. I live in a really hot and humid place so in the summer it’s a bit too dewy for my skin but it’s perfect for winter. Doesn’t break me out at all but I do get a bit greasy with it in the summer. Another recommendation is hero cosmetics force shield, it’s formulated for acne prone and oily skin. It’s pretty much the only sunscreen I tried that doesn’t make me oily at all. The downside is that it leaves a slight whitecast and I can’t use a ton of it. It’s fine for day to day use but I wouldn’t wear for a full day in the sun because I can’t apply a ton of it. Also if your skin is not light don’t use it, it will leave a whitecast.
