Hello,
I cannot confirm anything without examination but it can be due to
cherry angiomas,folliculitis,contact dermatitis,sweat dermatitis or dermatitis. Cherry angiomas are made up of clusters of tiny capillaries at the surface of the skin, forming a small round dome ("papule"), which may be flat topped.
When they first develop, they may be only a tenth of a millimeter in diameter and almost flat, appearing as small red dots.Pls don’t worry as they are harmless.
