Acne Help!

[caterpede]

Hi. i'm 20, a male and I live in Malaysia where the weather is generally humid, warm and the air is rather polluted (since I live in the city).

When I was in my early teens, I had very frequent breakouts. The acne is quite bad but not a serious condition. This continued until my late teens.

I have lots of open pores which are rather large. My skin is also rather dull and have some acne scars that are not that apparent.

I'm on benzac AC-5 now and have the occassional pimple. I also use Garnier Pure-A cleanser which contains exfoliating beads.

I would like to know how to close those open pores and whether there are any ways for me to give my face a healthier glow.

Also, are collagen supplements useful in improving the firmness and texture of skin?
