June 2022 in “Frontiers in Bioengineering and Biotechnology” The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.
