Folliculitis caused by Pseudomonas aeruginosa has been increasing due to the popularity of hot tubs, swimming pools, and whirlpools. The follicular pustules and inflammatory papules usually occur after an incubation period of two to four days and improve spontaneously in seven to ten days. Despite the discomforts of the condition, treatment is usually not necessary and may even prolong the infection. Since it is difficult to control the growth of Pseudomonas in hot tubs and whirlpools, attention to water conditions is the best way to prevent this irritating skin condition.
