I have a friend, Malay but very chinese look and she had freckles before. (we were in the same university).
After 3,4 years, I've met her again with no more freckles. She told me she had laser treatment.
I did not ask for details but she said it was painful, yet worth it. it was around RM300. She had it done somewhere in Sungai Petani, Kedah.
Judging from the result, RM300 is very, very cheap.
