Possible adult onset acne

I have trouble distinguishing between things that happen with my skin, since I have had acne most of adult life, but have began having different types of problems. I had a wart appear on my left forehead last summer which had to be surgically removed, and a case of folliculitis also on my right forehead right after Christmas which resembled the wart I had, but went away after several months of antibiotics and topical steroids. I now have a place which has came up under my left eye, at the midpoint of my nose. It started out as an under the skin raised place, barely noticeable, then got a head on it, and broke open on its own and started bleeding one day at work. It left a small spot which appeared to go away, but then got another head on it, which I picked at and it came off but didn't bleed, but is somewhat sore to the touch. I can't distinguish when it's just acne, or when it's time to be concerned. I always err on the side of caution, and go to the dermatologist very regularly, at least 2-3 times a year and have everything checked. There is no history of skin cancer in my family on either side that I'm aware of, but I've seen what skin cancer did to my father in law, and the devestating consequences it can have on your appearance. Is this maybe just acne, folliculitis, or what? It's always something with my skin, and I get really frustrated.

Hi,
This could be either acne or folliculitis.In either case it has been likely secondarily infected because of the manipulation of the area by you.
Wash face regularly and keep skin clean.Also you could apply Benzoyl peroxide cream  for the acne. .
Never pick at them because they will leave behind residual scars.
Folliculitis develops when bacteria, such as Staphylococcus, or a fungus enters the body through a cut, scrape, surgical incision, or other break in the skin near a hair follicle. Scratching the affected area can trap fungus or bacteria under the fingernails and spread the infection to hair follicles on other parts of the body.
Non-prescription topical antibiotics like Bacitracin, Mycitracin, or Neomycin, gently rubbed on to affected areas three or four times a day, can clear up a small number of bacterial folliculitis pustules or infected pimples.
