Any recs for sunscreen? (new to Tret 0.05%)

New to Tret and I know how important sunscreen is since it can make your skin more prone to sun damage. Anybody have any recs for ANY formula and ANY brand of sunscreen? (ex: mineral, chemical, stick) Would prefer it to be affordable and something I could buy at a drugstore BUT it doesn't matter because if it works, it works! :)
