make sure not to blow smoke on you hand AT ALL try to use your opposite hand to hold the pipe so you don't risk burning further, aswell it'll allow you to heal. It shouldn't overall impact the healing rate the only outcome is hurting yourself so be aware of what you're doing, i've picked up 400-500 degree pots while wasted/high, douse your hand with a thick layer consisting of a mix of vaseline/polysporin, i don't have a single mark from my burns thanks to this mix, and use the glove as instructed, otherwise i personally think its better to have in the open air, have a towel to rest your hand on aswell as not to get the stuff on everything, this mix will substantially increase the healing rate, can vouch for it.
