I think water is very important. Try to reduce oily and fried food. Drink more lemon water!
Other than the above, I also go for facial once a month. I think it is a must to have a deep cleansing to remove all the dirt on our face.
I have been to Radium Medical Aesthetics at Suntec to try out their ULTRASONIC SKIN CLEANSING and AGNES ACNE TREATMENT few months ago and the result is really GOOD!
I can see the difference after 1 session.
