In attempting to treat your condition, it's first important that you understand what Folliculitis is.
Folliculitis is a bacterial condition, or specifically, a bacterial infection of the hair follicle structures of the skin, usually those of the scalp, but can just easily affect the hair structures to be found on the face, like the beard, and other areas of the body. It should not confused with other conditions that similarly affect the scalp, like fungal infections or other such infestations.
A clue to the fact that the condition you have is folliculitis, is that each of the pustular like eruptions that are associated with this condition are clearly centred on the area of a hair follicle, and and commonly spreads to infect other neighbouring follicles, such that the whole area can sometimes pool with pus.
This is what usually happened in my case, until eventually the skin would rupture and allow the pus to drain out, similarly to acne, but with a sharp associated stinging.
