circular marks on my hands

I noticed a skin colored, slightly red mark on my left hand about four months ago.  It was raised around the edge and smooth and flat in the middle.  I left it alone and it finally went away for the most part.  It is still a bit noticeable but seems to be going away.  Now, I have a smaller circular mark that looks the same on the other hand.  The raised edge almost looks like scar tissue because it is very smooth.  I do not know what these are and what could be causing this.  If you know what it could be, I am interested to find out.  Thank you for your help.

attached is a picture of the newer mark on my right hand... the previous picture attached was of the one on my left hand that "went away" for the most part.

Hello,
I cannot confirm anything without examination but it can be granuloma annulare. It is characterized by round bump or rash appearing on the joints or back of hands. No treatment is required and it may go on its own. Severe cases may need steroids, non-steroid topical anti-inflammatory creams such as tacrolimus, cryotherapy, laser treatment or UV light therapy. Consultation of a dermatologist will be the best in your case.
I hope it helps. Take care and please do keep me posted on how you are doing or in case you have any additional doubts. Kind regards.
