Is this folliculitus? (photos)

Hi, I got molluscum 2 & a half years and think that may have finally cleared but not 100% sure as I developed a further rash in the same area around it & just couldn't tell what was what in the end. A dermatologist has told me that it's folliculitus. It's on my butt but I do have a similar rash on my chest & legs (gets much worse when I shave my legs / bikini line). I've attached a photo, could you advise if you agree? It's been there so long it's depressing me & affecting my confidence
