Hi There,
The best Powder to use for face is Ashoka Sandal Powder.It is very good for Face.
More over it acts as sun screen to ur face.Before venturing out u can put Ashoka powder to ur face and go out.But remember to wash ur face before applying powder to ur face.Even before going to sleep wash ur face ,so that powder is removed and the pores can breathe.
Please do not use cheap powders which are harmfull to skin. U can also use Oriflame Powder which is also good but does not act as sun screen.
