HELP me to heal my dry skin..

ok, first, i'm from tropical country, malaysia, weather is hot and humid, but i have dry skin and lips all the time, i put on lotion aft my shower, i put vaseline on my lips, drink quite a lot of water..

is there any way can heal this forever!??

one more suspect maybe because of the mic, as i'm a performer,, but i used to "stick" my lips on the mic, i'm not sure if the alcohol swap works on killing all the germs and bacteria on the mic or not.

is there anyway to clean the mic effectively (eg.alcohol swap)

ok, another points regarding first Question, i don't smoke, i drink a lot of water, seldom exercise, i put on vaseline lotion, put lip balm b4 sleep..

HELP!
