This simulated growth factor serum leaves skin noticeably smoother, tighter, and more glowy. Made with bioengineered growth factors meant to simulate the ability of platelet-rich plasma (PRP) to support skin repair and rejuvenation, plus hydrating hyaluronic acid, the crimson-red liquid sinks in instantly, and the results build over time. Smooth it onto clean, dry skin morning and night before applying your moisturizer.30 mL
