How do you open pores under your arm?

i think my pores are clogged none of the deodorant i wear works so how do you open pores under your arms





PLEASE HELP|||To open the pores in your skin, use warm water. To close them, use cold. Do this when washing your face as well, it works wonders to help with acne.|||A hot bath. Or your deodorant problem might be caused by something totally different.|||A hot towel also works to open pores, the steam and heat opens them, try that! Good luck
