Just that really. I chucked out my blusher as a film developed over it and seemed to seal the powder away. I bought a new bronzer just a few months ago and noticed it didn't seem to be giving me much colour anymore - rubbed my finger over surface and again it seems sealed in! Am fairly new to make up and had put the blusher down to it being old but I have been using the bronzer and power most days and they are still pretty new! Is there anything I can do or do I need to throw them out? TIA!
