What Are Pustules?
Like papules, pustules are small, round lesions. You’ll notice they’re red in color with yellowish or whitish centers (caused by visible pus). While inflamed, pustules are generally painless and do not contain a great deal of bacteria. The inflammation is actually the result of a chemical irritation from things like free fatty acids, which are substances that circulate in the bloodstream and are common in everyone’s skin, although it’s possible there are other causes.
While it may be tempting to pop a pustule – don’t do it. You could end up with a permanent scar. If you got one that’s particularly bothersome, see your dermatologist to have it expressed properly.
