How can i get rid of red pustules and marks on my skin?

See your derm: Adult acne seems to be increasingly common and can cause red pustules and marks on the skin. Rosacea can also do this, as well as bacterial infections such as folliculitis. Depending on the cause, there are almost certainly good treatments, so seeing your doctor will allow you to get a diagnosis and treatment, which may include topical creams and possibly oral medicines.
