I have been using vitamin c cream for about a little over a month... i have noticed that my red marks have lessened but it isn't drastic and by no means was it quick. however, I have noticed great improvement in indented scars on my cheecks. they have "filled in" and I am estatic with the improvement.
to reduce the "red scars" on my face I am undergoing V-beam laser treatments which has done wonders for me! ( i have only had 2 treatments ) and after seeing the before and after pictures of myself, I was in awe with the results.
i believe the vitamin c cream/gel will take time to heal the scars, but they will heal since the vitmain c inhances cell growth.
wish you the best of luck!
