White residue on lip after chapstick?

Whenever I apply chapstick or carmex indoors, no white residue form on my lips for the whole day if i stay inside.


But if I go outside or apply it outside, the white residue forms.


Why does this happen?


- thanksss.White residue on lip after chapstick?
maybe it is more humid indoors, so your lips are moist, resulting in a smooth swipe of chapstick. when you're outdoors the weather may be different, maybe drier, so your lips maybe more chapped with tiny skin protrusions, causing the white residue to form when you swipe on the chapstick because your lips are rougher
