Obagi Professional-C Serum 20%

I've used one bottle of Obagi C 20% since August and the skin discolorations that were resistant to anything and everything have faded by 80%.

It helps my skin get brighter, slowly fades my old scars and overall I feel like it keeps breakouts at bay. Plus it's really not drying.

Obagi has a cheap kitchen-like formula without any ascorbic acid stabilizers, so the ascorbic acid is already decomposed and orange.
