Would applying growth factor serum to a scar following microneedling increase existing hypertrophic scarring?

Question

I have been getting PRP microneedling treatments for an atrophic forehead line scar I got from an accident with great results. I purchased growth factor serum from one of those high-end cosmetic websites and am applying it twice a day, however, some of the edges of the atrophic scar are hypertrophic. Will applying the growth factor serum make the hypertrophic scar worse since it is supposed to stimulate collagen production? Or perhaps aid in hypertrophic scar treatment?

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.
