3 wks post op. Is the skin bunching near my incision line normal & what can I do to help my raised scar & lessen redness?(photo)

I am 3 weeks post op TT. I'm wanting to know if the skin bunching close to my incision line is normal. Also, what can I do to lessen my scars redness as well as keep it flat. I purchased embrace scar therapy but it has eaten away at my skin and is to painful to continue. Thank you in advance for your time and response.
