Acne scar sublimation with PRP refers to a treatment method where platelet-rich plasma (PRP) is injected into acne scars after a procedure called “subcision,” which involves breaking up the fibrous bands beneath the scar tissue, essentially “lifting” the scar to improve its appearance; this combination therapy is considered particularly effective for treating deep, atrophic acne scars by stimulating collagen production and promoting tissue healing within the scar site.
