I have received the picture,
Unfortunately the quality is not too good,
I understand that this can be difficult though.
It appears to be a small allergy rash OR a sebaceous cyst that may have ruptured.
The good news is that in either case NOTHING needs to be done, and this will eventually go off on its own :)
You can apply a moisturizer or even a mild steroid cream IF there is excessive itching or redness.
Try NOT to worry about it,
