This could be folliculitis or blisters due to tight clothing or friction.
Individuals who are predisposed to folliculitis should be extremely careful about personal hygiene. Application of antiseptic washes may help prevent recurrences. A topical antibiotic cream, mupirocin (Bactroban®), has been effective at reducing bacterial colonization in the nostrils. It is applied twice daily for a week and is repeated every 6 months.
If there any of the mentioned medical causes then treating those will reduce the occurence of the condition.
Some stubborn cases of folliculitis have been responsive to laser-assisted hair removal. This process uses a laser to destroy the follicle. This reduces the scarring that results from folliculitis.
