Cystic Acne Injection (Intralesional Triamcinolone)
Direct intralesional triamcinolone for cystic acne — flattens stubborn cysts in 24–48 hours, the dermatologist's emergency-acne tool.
Intralesional triamcinolone (commonly called 'cortisone shot' for acne) is the dermatologist's emergency tool for cystic acne — large, deep, painful cysts that don't respond to topical treatment. A small dose of triamcinolone acetonide (typically 2.5–10 mg/ml dilution) is injected directly into the cyst with a fine 30G needle.
The cyst flattens within 24–48 hours, dramatically reduces pain, and clears without scarring or post-inflammatory hyperpigmentation. Most-booked emergency dermatology service — particularly for patients with a wedding, photo shoot, or important meeting in the next 5 days who can't wait for a topical regimen to work.
Where it comes from, what's inside, who certifies it.
Intralesional triamcinolone (synthetic corticosteroid). Some formulations include benzyl alcohol as preservative — alcohol-as-preservative is permissible under most opinions but a stricter view exists. Clinic stocks alcohol-free formulation on request.
