I've used apple cider vinegar I used it as a toner and like once a week. Try it ure skin will start to become less oily acne will calm I usually applied and left on for a minute or two and just rinsed with water the vinegar is supposed to balance the ph on ure skin for chest or back just spot treat but use an old shirt the smell of vinegar is a wee bit too strong
I had my skin tested by some people selling cosmetics. They said hydration and elasticity is fine but I have a little less oil than I should have. My skin is little on the dry side to touch. Not at all oily.
I've suffered with horrible acne my entire life and I've been to countless doctors. The only thing that ever keeps my acne in check is my clarisonic aria. I wash my face night and day with the cerave cleanser. I also use tea tree oil with tazorac for spot treatments.
You're GP does not sound like they know what they are doing because antibiotics should not be taken for more than 6 months due to it's side effects. I suggest you visit another GP that will refer you to a dermatologist. There is a cream that a dermatologist can perscribe for the painful blemishes; sorry, I don't remember the name.
Sadly no matter what I'll always end up with one or 2 blemishes and it's hard not to resist and I end up picking them. However I make it a point to clean throughly with my aria and put a scar cream as well as tazorac; I'm in love with Kate summerville's scar cream.
In the meantime, I suggest that you brush up on your "concealing acne skills" because it will really help with your self esteem. No matter what you do makeup wise, make sure you wash it off at the end. Here's a link to a video which I found extremely useful for myself. I actually wish I had found this sooner. http://m.youtube.com/watch?v=PljbzaUlA8o
