Welcome to healthcare magic forum.
Thank you for your query.
I understand your concern regarding your skin problem.
it may be due to bacterial infection or some benign lesion.
You can apply antibiotic cream over it.
Do not press or popped the lesion.
Better to consult dermatologist
for proper treatment.
In severe case you also need to take some medicine orally.
I do not think it is related to soap
I hope I answered your question.
