My arm has always had this dark line that goes down my arm. Where one side of my arm is dark and the other side is really light. This has been there way before I started lightening. I've been using Kojie San Soap/Fair n White aha lotion and I can't say anything has happened on my arms. My hands however have lightened greatly. I'm thinking about using dead sea salt soap. My knees, elbows, arms have been very stubborn.
Also what is everyone's thoughts on me mixing my Retina A/ HQ/Kojic Acid cream with Fair n white aha lotion?
