Intralesional Steroid and AcneA dermatologist may prescribe an injection of cortisone directly into a pimple, if it's big or\and doesn't seem to be affected by other treatments. This will normally reduce redness and inflammation almost instantly. This has the effect of flattening the pimple and making it easier to cover up with makeup, and can also help in the healing process. There are some side effects with this method including fat and dermal atrophy (depression of the skin at the point of injection), bacterial infection, hypopigmentation, recurrence of the acne. Intralesional steroid should be discouraged as the sole method for the treatment of acne, while it is utilized by many dermatologists and family doctors. Systemic and topical steroid are both known for inducing steroid induced acne or "steroid rosaceae". Therefore, there are long term consequences of this treatment which should not be ignored. Injected steroid can cause local immunosuppression, and can encourage the formation of local abscesses. Rarely, intralesional steroid can induce permanent fat atrophy, and litigation has been filed and on record. If utilized, the dose of the steroid should be minimal, and other methods of treatment should be concurrently utilized. Steroid injection alone does not address the cause or causes of acne - the occlusion of the pore, bacterias, or the excess sebum.
