I've had a great experience with First Aid Beauty's New Radiance Serum. I've only used it a week and it has almost completely cleared any dark marks/acne scars I had. And I tend to break out along my jaw/chin and that has been reduced too, which is a benefit I didn't expect.
hey, you should definitely try the Ole Henriksen three little wonders kit because i have heard amazing things about it helping with acne scars. The serum in the kit has vitamin c which will help brighten and fade. The treatment has glycolic acid in it so it will ex-foliate skin to bring non-scared skin to the surface. The moisturizer has hydroxiquone in it which will help fade. keep in mind that whatever product you use it will take time. hope this helps.
