Many new mothers continue to have acne issues after pregnancy due to fluctuating levels of their hormones. Breast-feeding mothers may be concerned with the safety of using acne treatments. Certain medications, topical and oral, may affect the mother's milk and add potential harm to the baby. However, there are many safe acne treatments available that have a low lactation risk. Similar to any medications, it is always best to consult with a physician first.
When attempting to treat acne, many people use over-the-counter creams and cleansers, often to no avail. The reason for the lack of results, says the Mayo Clinic, is that these treatments alone can't address the real cause of acne: a bacterium called Propionibacterium acnes. In order to get rid of acne, your doctor may bring out the big guns---a combination of oral or topical antibiotics---to get the job done.
