3. Underarm deodorant
Underarm deodorant will heal blisters at home. When you use deodorant, use the antiperspirant because it prevents moisture. Blisters thrive in moisture-rich environments. Just rub the antiperspirant onto the blisters and it should dry it up. Don’t try to mess with the blister infected area. Just let the antiperspirant do its thing and every time you wet your feet just check it.
If it’s not gone, just rub more of it onto your feet. An important thing to remember is to use an antiperspirant that is not going to be used under your arms. You don’t want to spread the blisters to other areas of your body. It doesn’t matter if you use the gel or the white form of antiperspirant. You can try both to see which one works best for you. When you wear sandals, you can even put the antiperspirant onto your feet. No one will notice that you have it on.
