research Potential genetic associations of acne scar phenotypes: IL1A in fibrotic scarring and CYB5R1 in atrophic scarring
This study found that certain genetic variants, specifically CYB5R1 and IL1A, may be linked to different types of acne scarring, with CYB5R1 associated with atrophic scarring and IL1A with fibrotic scarring, indicating a potential polygenic nature of acne scarring.
