I’ve had a red mark under my side burns down my jaw line under my contour. I’ve had it my whole life but I’m not sure if it’s rosacea
Hello and thank you for your question and photos. There are various causes for redness to the skin, including congenital and rosacea. It is difficult to provide a proper evaluation of your skin through photos, and thus I recommend a consultation by a board certified dermatologist for evaluation and discussion of appropriate treatment. Best of luck.
