Best sunscreen for hot countries!

Hey there! I have a combination and acne prone skin and the school air usually makes my face SO oily & greasy which leads to breakouts. I’ve tried many sunscreen, they are all good. It’s easy to blend, lightweight, and no whitecast! But the only problem is it becomes greasy after a few hours when I'm at school. Both our house and the school doesn't have ac but idk why it's greasier when I'm at school. But when I tried this sun serum from Skin1004, my face is not greasy and oily at school anymore despite the heat! I love everything about this sun serum! I didn’t have any problem with this, it’s so perfect!💙✨ If greasiness is also one of your problems when using sunscreen, then I highly recommend this one!
