Carbuncles are a large boil full of pus and very inflamed. They are best treated with drainage and usually topical and sometimes oral antibiotics. 80% of the improvement can come from just drainage. Apply heat to help it come to a head, or even apply a drawing salve like an acne mask with sulfur of salicylic. They can resolve spontaneously if they are not large and if you don't make it worse by manipulating it incorrectly. Dermatologists are well-versed in treating carbuncles. Cultures usually show Staph Aureus and even MRSA, especially with larger carbuncles and if very painful.

For example, rolling scars need Subcision and sometimes Microneedling; ice pick scars CROSS, box scars Resurfacing with either ablative lasers, or chemical peels, atrophied scars need fillers and hypertrophic scars need Intralesional medications. PRP is used either with Microneedling or with fillers. Hope this helps. Dr Rullan
