What is the best treatment for Scar Removal Redness? (photos)

I had an Adams Apple reduction 2 years ago after that Hypertrophic scars show up and then I had 3 times Kenalog injections, which is making it all flat 90% except the small white spot in the middle of the scar is still hard My questions is 1. How do I get rid of small hard white spot? Do I need more Kenalog injections? or should I leave it as it is? 2. What's the treatment name I should go for the redness around? Sorry for poor English, Any answer will be greatly appreciated.
