I tink if not wrong, Dr Ong told me that the dirt will be pushed to the surface,something like tat, tat's y the pimples pop out.
My face is T-zone. Dr Ong also recommended me AHA but now i do not use. It's better to check the level of AHA u r suitable. Too high concentration can redden yr cheeks, cause a stinging effect on me.
My case is the same like u, my face was smooth during my teenage yrs and it only started breaking out when i was hitting 25. Dr Ong told me that some pp r like tat, cos of hormones. Guess i just started to grow up heehee. Was told to use her antibiotics as long as i grow old. Once I grow old, won't get pimples. But then, i tink i'll get wrinkles.
I've seen Dr Ong since 2001 when my face suddenly erupted with pimples. I feel that her medication helps, some guys even went to her clinic, i suspect, to seek help on pimples.
