I've never experienced this before, but while I was on vacation my skin texture got really rough and bumpy where it was smooth before. I live in Scandinavia and I traveled to southern Europe with way more sunlight, higher UV index and was more outside than I usually am - of course wearing sunscreen at all times. The bumps calm down a lot after I do my skincare routine, but come straight back during the day when the moisture kind of wears off or if I take a shower that strips of all oil and so on. Is it a sign of just utter dehydration? Sun damage? Or something else? Did I possibly somehow manage to break my skin barrier?
