Diagnosis established as moderate atrophic acne scars with global acne scarring system (GASS) is 21. Patient treated with blunt canula subcision, hyaluronic acid (HA) filler, microneedling radiofrequency, 90% trichloroacetic acid chemical reconstruction of skin scars (TCA CROSS) and application of salmon polydeoxyribonucleotide (PDRN). Patient also received topical 0.05% retinoic acid, 4% niacinamide, and sunscreen for daily. After 10 days, there is flattening and disappear of ice pick and boxcar, elevating of rolling scar, GASS score is 15. Blunt cannula subcision and HA filler is safe, effective for rolling scar through fibrous band breaking and prevent re-adhesion. Microneedling RF is effective for boxcar, otherwise 90% TCA CROSS preferrable for ice pick scars. This combination procedure leading cellular necrosis in epidermis, collagen in dermis, and stimulate regeneration. Application of Salmon PDRN may promote wound healing, hydrate the epidermis, and prevent dyschromia.
