Can you tell me if there's any science to support claims that promote the benefits of 'bioengineered human protein' (KGF) found in cosmetics products?"
Off the top of my head, NO there is no scientific evidence that bioengineered human protiens will have any benefit in cosmetic products.
However, we'll look into it. If there was any science to back it up, this would've been big news in the industry. The fact that it wasn't makes me skeptical.
But, we'll reserve judgement and get back to you.
