A cortisone shot for acne is a small steroid injection placed directly into a large, deep bump. In 2026 it remains a guideline-supported option for faster relief of painful nodules and cysts, while the supporting trial evidence stays small and dosing questions remain. The shot does not treat everyday pimples or prevent new breakouts. It targets occasional stubborn lesions alongside ongoing topical or systemic care.

Which breakouts qualify?
Cortisone shots are reserved for large, deep inflammatory nodules or cysts. They are not for ordinary pimples or pus-filled pustules.
The American Academy of Dermatology frames them as treatment for occasional or stubborn lesions rather than for patients with multiple lesions. A painful cyst before an event is a typical example, while widespread breakouts need broader care.
What do current guidelines say?
The American Academy of Dermatology's 2024 acne guidelines recommend injectable corticosteroids as an option for larger acne bumps to achieve more rapid relief of inflammation and pain, alongside combining topicals and limiting oral antibiotics, according to the Academy's updated guidelines via Newswise. The UK National Institute for Health and Care Excellence also recommends intralesional corticosteroids for severe inflammatory cysts because they can be painful and unsightly, based on committee experience plus available studies, as explained in the NICE rationale for NG198. That support rests on limited trial data.
NICE found only a small randomized experiment in 17 people with severe nodulocystic acne testing triamcinolone versus saline and betamethasone versus saline, with triamcinolone showing short-term improvement. The newest physician reference continues the cautious approach. World Anti-Doping Agency acne guidance from January 2026 lists intralesional triamcinolone 1.25-2.5 mg/mL, an example of the low-concentration practice clinicians use to limit harm.
How fast does a treated cyst improve?
A treated lesion typically softens and shrinks within 24-72 hours and generally improves over 3-7 days, according to the GoodRx dermatology guide. That course is shorter than a cyst that might otherwise last weeks. Faster settling may reduce scarring or dark spots.
The benefit is local to the injected bump. Ongoing acne care still matters because the shot does not stop future lesions. Topical or systemic treatment continues after the injection.
What are the main risks and safeguards?
Important harms include skin atrophy with depressed scars, lightening or darkening of skin, visible small blood vessels, short-term pain, and rarely infection. Risk rises when injection goes too superficially, with darker skin also facing higher concern for light spots.
Injection-site atrophy usually begins within 2-3 months. It often fades over weeks to months but can persist 6 months to 2-3 years, and case reports describe saline injections for persistent dents or color change. Practical safeguards help lower risk:.
- Treat only a selected large nodule or cyst.
- Use low concentration and small volume.
- Place the injection at the correct depth.
- Continue routine acne care to prevent new lesions.
