bubu, spagal,
Don't use too strong cleansers even for oily skin, if your pores don't clog to grow into volcano mountains, it's ok. Over-cleansing leads to dryness, and irritation (natural tendency to scratch pimples too), and stimulates more oil secretion and your pores will grow larger too. This is my case. And when your pores grow larger, dirt goes in easily, and then pimples get inflammed easily, so it becomes a vicious cycle.
I believed in sea derived products and that they happen to be good at oil control too. Once I went to Tioman underwater, despite the strong sun, my skin came back much better which I believe is due to my time under in the very clear sea water. I was suprised cos I thought I would be sunburnt/skinburnt though I used some slight sunblock on the face. I decided the sea water must have some therapeutic effect since I also use sunblock on face in Singapore, but my face didn't improve.
But when it comes to packaged skin care products, the chemical properties like liposome delivery, oil-free, gel, non-clog, etc are important. e.g., In colder and drier countries, I prefer Nivea/Eucerin as unlike other creams they do not clog and they form something like an insulating wax layer on top which doesn't feel like oil/cream.
