Representative standard light clinical photographs of differences in skin outcomes at baseline (top) versus following microneedling treatment (bottom) with a novel multiple-active-ingredient formulation (left) or conventional microneedling protocol with a hyaluronic acid control serum (right). (i) An increase in erythema is noted at 1 h from baseline across the forehead and cheek with the control serum. (ii) Improvements in luminosity are noted at 1 h with the novel multiple-active-ingredient formulation across the browbone and cheek. (iii) Improvements in skin texture are noted at 28 days with the novel multiple-active formulation across the forehead
