Hello,
Without examination it is very difficult to confirm a diagnosis, but it can be solar keratosis(small rough or scaly areas of
skin due to damage
from sun exposure), Dermatosis papulosa nigra(firm, smooth, raised, dark brown to black bumps occur on the face and upper trunk; usually runs in families) , seborrheis keratosis(small lumps due to a thickening of an area of the top skin layer) ,syringoma(bumps caused due to overgrowth of cells),moles or freckles.
