Answer

Although gram-negative folliculitis is largely a complication of acne vulgaris and thus is expected to follow the age distribution of that entity, a slightly increased age at onset has been observed. The tendency for gram-negative folliculitis to begin after the early teenage years is most likely because most patients who develop gram-negative folliculitis have undergone treatment of acne with a broad-spectrum antibacterial agent for a prolonged period.
