thank you very much.
i used to have dry lips last time when not taking enough water. but it's nothing like this. it's like a whole layer of dry skin on my upper lip. i tried to apply some vaseline, it helps but it cannot cure. everytime i stop, it will come back. so, i have to apply it like everyday. i have this for about 1 year already. but i never consult any doctor.

as for the private part. sorry, i cannot post a photo here anyway, talking about my working hours.. hmm.. ya, sometimes i work more than 12 hours a day. but just office work. although sometime after come home, i will take another 3-4 hours before bath. but surely i will take bath every morning and night and quite thoroughly (at least after i have this symptom )  and surely i will change underwear. I don't have any medication with me as of now. So, sometimes i even apply vaseline for this problem. i don't know if it helps.

If I want to make my teeth straight, how much will it cost? I don't want to wear braces. Looks ugly. 

Also, if want to clean the teeth make it whiter, how much?
