I had a cut-like split on the edge of my nostril that would not heal with numerous other products for over 9 months. I tried hydrocortione cream which usually works well on blemishes; I tried other agressive lotions, including ones with alpha-hydroxy. None of these worked. When I discovered Dr Max Powers SCAR SERUM, it worked within a couple of weeks, completely healed the split back to totally normal. You need to be patient for whatever number of days that the skin still has a peel-able layer. Eventually it will completely smooth out. My experience reflects what "The Lil Scar that Could" says, that it works for healing and preventing a scar more so than getting rid of an existing scar. I believe it can work to improve existing scars, if not remove them, especially if one if persistant. This serum goes a LONG way on small cuts or blemishes that can create a scar if left untreated.
