Since today morning I noticed that I've got a red patch under my chin and can't figure out what caused it? (photo)
since today morning I noticed a red patch under my chin and right now it's 9 in the night it's been there since morning it has not faded nor changed its colour or shape and so I was extremely concerned as to what can it be. It does not hurt nor sting. Any suggestions as to what it could be or how I could possibly treat it would be rest thanks!
