Hi there ~
Red spots on the body could be anything. I advise you to consult a dermatologist
along with your boyfriend who might be able to help out with diagnosing the condition and recommending the right treatment. However, if the red spots are akin to acne
which is very common in your age, it is not something that I would recommend treatment for unless it is very bad. I hope you do see a dermatologist however. Take care and I wish you good health!
