Abstract

BACKGROUNDHyaluronic acid (HA)-based fillers are effective at mitigating acne scars due to their filling effect. Complexes of high and low molecular weight HA demonstrated a delayed biostimulatory effect.OBJECTIVEThe authors sought to compare the results of acne scar treatment using a filler composed of complexes of high and low molecular weight HA versus a traditional cross-linking HA filler.METHODSThirty patients with moderate-to-severe atrophic acne scarring were included in this prospective, split-face, double-blinded, randomized controlled study. Each underwent 3 monthly injections of a novel formula of combined high and low molecular weight HA (P) to the base of acne scars on 1 side of the face and traditional cross-linking HA (JV) filler on the other. Patients were evaluated 6 months after their last treatment for objective and subjective improvements.RESULTSFor JV, statistically significant reductions were observed in the acne scar volume but nearly no change in elasticity and stretch during early treatments. For P, no significant differences were observed in early treatments; however, statistically significant improvements were observed in later visits.CONCLUSIONAlthough the traditional JV filler demonstrated an earlier impact than P, the latter produced delayed positive changes that were more pronounced than the traditional filler.
