When can scars be treated after using Stiva A?

I'm applying Stiva A every night because of my millet. It
 's been a little over a month since I started applying it, so this may be a hasty question, but... I'm posting this because I feel so confused and depressed every time I look in the mirror.
 Do you say rolling scars on my cheeks? It's not deep, but the area is a bit wide... These are scars that were created by tearing and scraping off the millet.
 Does Stiva A help with these scars??
Occasionally, it is said that scars have become lighter after using Stiva A for a long period of time.
 If this is true,
 how long should I use Stiva A for it to be effective for rolling pitted scars?

If it doesn't work,
 is it a good idea to give the skin some time to rest
 after completing the millet treatment with Stiva A
 and then undergo scar removal treatment?
I am worried that my skin will become too sensitive to perform scar removal treatment immediately after using Stiva A.
