Pus-filled bumps and definitely not normal pimples!!!

About myself...
I am a male turning 22 this year and I have problems with my face which I am running out of hope reviving it.

I think my face was in a bad shape mainly because I had chicken pox last April. But I recovered weeks later. While I thought a year had passed, it is intriguing the symptoms (pus-filled bumps) are not residing and frequently recurring. I am aware that my facial scars need time to fade but after numerous googling and facials, not to mention the cash outflow, guess what, I decided to upload some pictures.

(it's kinda disturbing, if u zoom it)

So what does everyone think? I consider my skin to be fairly oily and moderately sensitive. Not the extreme case. I get blackheads in the recent years.

it might be useful to know that I left Singapore for the UK to study last September and sometimes I wonder whether the problem lies with the water or climate. On average, I sleep at 10pm-12am and wake up at 8-9am. My diet includes the usual characters of food pyramid and I loved my greens. I am not a fan of fried stuffs but I eat chocolates for energy on the run. However I have cut down the intake to maybe 3 bars (e.g. Twix) a week. I drink adequate amount of water and I go to the gym 5 times a week.

I have used the entire family of Clearisil ULTRA products early this year. Results were fledging and inconsistent and breakouts still remained.

I had near-perfect skin before chicken pox hit me like bee hordes last year. My face was the main casualty of this disaster. I had almost none on my lower body.

My friend advised me to try Dermologica so I bought the basic mediBac clearing kit which included dermal clay cleanser, mattifier, oil-free lotion and overnight clearing gel. Currently, on top of those, I am using Lush herbalism (a kind of paste) and fruit masks (cosmetic warriors, etc..) So usually I will first the paste, followed by the cleanser,

Yea like what many says, I try to wash my towels and pillow cases once or twice every fortnight.

Just 5 minutes ago, I bought glycolic acid on eBay. Not sure if it works but oh well.. desperate is all i can say.

So please, experts and those-who-had-and-prevailed out there, I NEED ENLIGHTENMENT.

many many thanks in advance!!
