In a word, nope. "There are a variety of skincare products that contain growth factors, some from botanical sources, and others from other areas like human foreskin. It's unclear which of these is actually the best, so we need to rely on published data showing clinical improvement," points out Zeichner. If you are going to go the EGF route (be it with said penis facial or another topical product), the best time to start using these ingredients is while you're young and your skin is still relatively healthy, he adds. So, think of them as more preventative than curative.

Don't have the big bucks for a penis facial and/or are just disturbed by the idea? Yeah, us too. If you're curious about EGFs, consider going the product route. The Vie Collection Time Control Deep Wrinkles EGF Serum, $176, uses a peptide that has the same molecular structure (and effects) as EGFs, while Bioeffect EGF Serum, $159.98, uses a plant-based EGF replica that comes from barley. Still, at the end of the day, Zeichner recommends that these be used alongside tried-and-true anti-aging powerhouses (think retinoids and antioxidants) rather than as a replacement.
