This is how to perform tayammum: 1- Say Bismillah. 2- Strike the ground once with the palms of the hands. 3- Wipe the back of the right hand with the palm of the left, and the back of the left hand with the palm of the right. 4- Wipe the face with both hands. 5- Recite the same dua's that are recited after wudu.

Applying cream on the face does not break wudu nor does it break the fast.

If women pray in congregation, then the one who is leading them should stand in the middle of the row, because that is more concealing, and a woman is required to cover as much as possible.
