A cortisone injection for cystic acne is a dilute steroid shot placed directly into a painful cyst to calm deep swelling and pain. It often flattens the bump in 24-48 hours, clears it in 3-7 days, costs about $50-$100, and can leave a dent or light patch.
Dermatologists use dilute triamcinolone to suppress inflammation inside the nodule. That reduces swelling, redness and pain at the source. The American Osteopathic College of Dermatology describes this targeted use for deep cystic lesions.

How fast does it work?
A treated cyst often starts flattening within 24-48 hours. It often clears fully in 3-7 days. SL Clinic gives that timeline in its clinical page on cortisone acne injections.
Tenderness and redness usually ease as swelling drops. That speed suits a wedding, photo, or painful flare. The American Academy of Dermatology's 2024 guidelines recommend the shot as added therapy for larger bumps. The goal is faster relief of inflammation and pain, as described in this updated guidelines summary.
Which breakouts qualify?
Mayo Clinic lists direct steroid injection as an option for nodular and cystic lesions. It is an in-office step for selected bumps. A dermatologist treats the sore, deep nodule and leaves surface pimples to other care.
The American Academy of Dermatology positions the shot for an occasional or stubborn inflamed nodulocystic lesion. It is not for people with many lesions. Widespread breakouts need topical or systemic therapy instead. It tends to fit when:.
- one deep, painful cyst swells before an event
- a single stubborn nodule stays sore despite routine care
- breakouts are few, not spread across the face or body
What are the main risks?
The main local risks are thinning of skin or fat that leaves a dent, plus lightening that leaves a pale patch. Risk rises if the dose is too high or placed too shallow. The UK National Institute for Health and Care Excellence flags both effects in its evidence review on intralesional corticosteroids. Pigment risk is higher in darker skin. Dermatology reviews also list pain, bleeding, ulcer, infection, stretch marks, allergy and rare hormone effects.
These events are uncommon. Using a low concentration and small volume lowers the chance. GoodRx Health notes dents and color change are often temporary but can take 6-12 months to fade. Report any dent or color shift promptly. Do not seek a repeat shot in the same spot without dermatologist spacing.
What does it cost and what happens at the visit?
The shot happens in the clinic. Mayo Clinic confirms direct injection is an in-office option for selected nodular and cystic lesions. One visit can cover one or more chosen bumps. Ipsy's dermatologist-reviewed guide puts a single shot at about $50-$100 out of pocket.
Price can reach $150-$200 per lesion based on location and number treated, per its dermatologist-reviewed cost guide. Many in-network plans cover the injection when medically indicated. Ask how the fee counts lesions and whether the office will bill insurance. Ask about dose, placement depth, and spacing if the same spot flares again. Good spacing and low dose lower dent and color risks.
