What the gurus are saying

This serum earns consistent praise for visible smoothing within a week and clinically proven improvements in skin thickness, firmness and evenness, though the steep $275, $300 price tag gives some experts pause. The standout is its human-derived growth factors backed by strong clinical data in human subjects, making it a top choice for those investing in growth-factor serums and addressing sagging or loss of elasticity. One expert notes the vitamin C component may not justify the cost on its own, so the value case rests on the growth factors and peptides rather than the full formula.

"The Neoccutis Bio Serum Firm is one of the two serums I would really recommend if you're going to invest in growth factors because it's the most studied and has actually shown clinical improvements in human subjects. It will run you about $300, and it has shown to lead to skin improvements including thickness of skin, better tone in skin, more evenness in skin, and it contains human-derived growth factors, which is the creme de la creme."

"If you have a lot of money and you're willing to spend $275, Neocutis has a Bio-Serum Firm that contains this form of vitamin C in addition to glycerin and certain growth factors. Are you spending your money on the vitamin C? I do not know. Again I do not know enough to recommend this product, but let me know in the comment section if you've tried it and if you like it."
