At day 90, ≥ 75% overall improvement was reported in 72% and 19% of patients in the HQ/tret + IPL group and the placebo + IPL group, respectively. HQ/tret + IPL was also associated with significantly lower mean hyperpigmentation scores at days 30, 60 and 90 (P≤0.05), and significantly lower mean laxity scores at day 90 (P≤0.05) compared with placebo + IPL. Adjunctive use of the HQ/tret system enhances the improvements in facial skin achieved with IPL treatment.
