You most likely used a styptic pencil and that is not the same thing as an alum block. the styptic is very harsh and closes off nicks and cuts. The alum block that you want to use on your face is potasium alum and us almost always sold as shaving alum. It is an astringent and will not stop bleeding in a cut, but it will serve the same purpose and using witch hazel or any other astringent and closes your pores and tones your skin while calming down burn.
I buy mine at the local Indian market for a couple of bucks and they last years if you don't drop them. I am going to guess that your ingrown hairs are from scraping around with the DE and the combonation of the styptic pencil.
