Living in a humid climate like Bangladesh requires a sunscreen that provides robust UVA/UVB defense without leaving a greasy or sticky residue.\n\nKey features to look for:\n- Chemical vs Mineral Filters: Chemical sunscreens absorb seamlessly without white cast, while physical filters with Zinc Oxide calm acne-prone skin.\n- Sebum Control: Formulations with Silica or Green Tea help keep oily T-zones matte throughout the day.\n- Reapplication: Remember to reapply every 2 to 3 hours if outdoors!
