Can I use Alum powder on my face?

I have spots (post pimple spots %26amp; acne marks) on my face. I read that alum+rose water+egg gives a good result.





Does anybody know about this.


Please give me suggestions on this because I don't want to try this about which I don't knowCan I use Alum powder on my face?
Styptic pens men use when they cut themselves shaving have alum in them, so I would say yes you can. I use it for canker sores. It is a powerful astringent and antiseptic.
