My child has a cold and doesn t wipe/blow her nose that well or thoroughly. She has suddenly developed a number of little pimples under her nose - surely there is a connection between these? Seems too big a coincidence. She is only 7 - she doesn t get pimples!
Hello. I just read through your question. The area under the nose often gets very Chat Doctor.  This gives bacteria an opportunity to cause the pimples. I recommend using a moisturizer in the area, especially during colds. They will heal on their own.
