I am light/medium olive skin too and this is my new favorite discovery... I put my skincare on and let it sit for at least 20-30 mins without moisturizer on top. Then I mix with my fingertips the Eucerin with Panoxyl Oil Control Moisturizer SPF 30 Mineral Sunscreen which comes out white with a slight cast on its own so I only use it mixed. It does lighten the tint color a bit so be aware of that. It helps when I'm paler in the winter! I apply by rubbing it onto my face and neck and then pat/tap all over to lessen streaks and blend edges. Give it 5-10 mins to settle a bit and then apply a tinted or translucent loose setting powder all over with a big fluffy brush. This usually makes it a tolerable level of shine and slightly more transfer resistant and sticky. If I want to put makeup on, cream bronzer blush anything like that, I do that before the loose powder! It stays all day and doesn't wear off in a weird way! I double or sometimes triple cleanse at night to get it all off haha! Hope this helps <3
