I had experienced a serious outbreak 2 years back. I used many products and eventually chanced upon some reviews on Niks Maple Clinic (by forummers on Cozycot). For the complete acne treatment, I visited the clinic for about 3 times at a month interval and spent a total of less than $500. The process might vary as it depends on individual's conditions. I also had my chicken pox scar removed via subcision and laser.
There are 3 branches in Singapore, i only visited the one at The Heeren (by appointment only). For consultation with Dr Ong, one may probably wait for at least 2-3 months.
