I have scars that are healing and I need them and I am trying to cover them. I use dermablend and have tried other products and they all end up digging into the scar lines. I used a primer, like urban decay all night, dermablend silicone, estee lauder smoothing, loreal type putty. I tried beauty mixers, fingers, brushes; nothing works to cover them. Is there a primer or product that could help?
