pb50, I get these too. I think it is from my skin being so thin on my hands and arms....all those years of tanning when I was young has made my skin thinner as I have aged.

My hands and arms tend to be the primary site of these. I can barely bump my hand or arm and get these. It takes a while for them to fade away.

I put a blemish stick cream on them and it covers them....if I don't have too many! Blessings...
