1. You can try to reduce your food intake, especially oily and fried foods.
  - consume less salt, less nasi lemak, rendang, etc. 
  - eat lots of fruits and vegetables.

2. Wash your face, twice a day.
  - choose a gentle soap and make sure it doesn't dry out your skin too much
  - use warm water to clean your face.
  - don't use harsh soap or soap that is designed to dry out the skin.

3. Choose only water-based products and non-comedogenic cosmetics.
  - don't use oil based cosmetics / products.

4. Exercise at least 3 times a week and get well rested
  - Physical stress may trigger the development of excess oil on your skin.

5. Use a deep cleaning facial mask.
  - I've tried shea butter and honey coz it doesn't dry the skin.
