I was on gluthathione acetyl ((4,000) and vitamin C liposomal (4,000) and I didn’t see any results. I did this for three months . I didn’t apply any topicals because I wanted to see if it worked with out. I’m going to start again with IV and Kojie San soap only and see what happens . I’m surprised in 2020 we still don’t have a safe and permanent way to lighten . I had high hopes for gluta and vitamin c.
