Cortisol is a naturally-occurring hormone in the body that can affect immune cells. Corticosteroids can be given orally (as a pill) or topically (as a cream, gel, or ointment). Because topical corticosteroids are applied directly to the skin and not circulated throughout the body, patients being treated with them may experience fewer side effects.
