I love your skin tone
I would recommend a deep peel like YPO or GPO for starters to speed up your results. Once you have peeled you can add your lighteners – RA, nadinola , LA. Add a vitamin C serum in the AM in your routine. Also try rotating thai soaps like Asantee & K brothers with your kojisan. They exfoliate very well. Keep up the weekly LA peels and repeat the YPO/GPO every 2-3 mths and do manual exfoliation with sugar scrubs e.g. from tree hut. For skin building try adding oils & butters to your regimen e.g. almond oil, shea butter.
Add supplements like vitamin C, glutathione, to your regimen. These will give you an amazing glow and help lighten from inside esp the knuckles. Check out this thread – http://www.skincaretalk.com/showthre…hlight=chuchu1. The supplements gave her a big boost. HTH
