What is it?

A steroid (triamcinolone) is injected into the lesion in the dermis, where its anti-inflammatory and immunosuppressive action quickly calms nodular and cystic acne.

Who it's for

Large, firm, painful nodular or cystic acne. Swelling, redness and pain noticeably decrease within 1–2 days after the injection.
