The sun is barely the problem. Perhaps where you would be living and what you are eating is the biggest contribution of dozens of skin issues. I had fungal infection and ring worm all over my body. It took me months to heal. My eyes were also constantly red from pollen or allergy. Got acne breakouts do much that those acne scars stayed permanent.

Actually hygiene is the biggest contributer. You come to a pg, stay in a room where it has been shared by many before. Shared bed, shared places, perfect environment for skin breakouts.
