My face seems to sweat so easily. I wash my face in the morning and then if i walk briskly to catch a bus my forehead would start to bead with sweat (sport and exercise is my life by the way so its not because im unfit!). I am a twin and my brother doesnt seem to have this problem and isnt as oily as me either. I think this may be because of all the chemicals i have put on my face in the last 3 years.
