How long can it take to see good results from Pulsed Dye Laser on a mole removal scar?

I’ve had 2 rounds of pulsed dye laser for a mole removal scar that wasn’t fading on my face. The first was around 18 months after my mole removal, and the second at 21 months. It’s now coming up to 7 months after my first PDL, and 3 months after my second; although I can see some change/fading I’m still yet to see anything dramatic. My scar also tends to flare up when I get warm - such as doing excercise. I was told the PDL was shrink/destroy blood vessels. Will I see any further fading?
