Dermatology Questions? Ask an Online Dermatologist.
Hello from JustAnswer.
Could you attach a picture of the blemish?
Actually, this has more of an appearance of an inflammation of the lips at the corner of the mouth, called angular cheilitis. Although this can occur as a type of bacterial or fungal infection, it also can be a reaction to something to which the lips have come in contact or from nutritional deficiencies, such as of B-vitamins or iron levels.
Herpes can also affect the corner of the mouth, but this does not have the typical appearance of a herpes lesion.
There are a couple of simple home interventions that can be done. The first is simple cleaning with soap and water, then the application of an antibiotic ointment to cover common skin germs or petroleum jelly, which can protect the area from substances to which it may be coming in contact. Taking a general multivitamin supplement is also reasonable.
Yes, it would be appropriate to stop the Abreva and use the Neosporin.
You are very welcome.
