Good luck! You can bring an oatmeal bar for your face (Aveeno- its a USA brand). When I was a teen that's what the doctor told me to use for my skin when I was breaking out. Its portable, simple and can't do any harm. Any bar soap has the tendency to dry the skin because of the residue it leaves and the high chemical content. but that's your best shot i think. You're not allowed to have basic skin care products? That sounds a little harsh! Mario Badescu (you can get it at KIT) has nice sensitive skin products and a great shaving cream.
