I had laser treament to remove black pigmentation on my face recently (on Feb 24, 2011). However, the black marks became worse and more permemtnant than before. I read your website and noticed that AHA and whitening product cannot be use after laser treatment. But I was given both and was told to use it when wound healed (approximately 8 days after the treatment). Is it the cause of the more permentnant black mark. Can I undergo another Laser treatment to have it fixed? How long I have to wait before I can have another laser treatment? I understand that you have C6 laser treatment in your clinic, and how fast can it get ride of the back marks on my face and how much it will cause? Looking forward to hearing from you soon. KY Li

The “Black Mark” on your face caused by AHA product after the laser treament most likely is “Post-inflammatory hyperpigmentation”. It is not permentnant. C6 laser treatment and together with use of some cream could speed up the healing process. The pigmetation will be resolved after several months. The basic laser treatment is $4,380/10 times.
