BIO SERUM FIRM is a sophisticated combination of both Human Growth Factors and Proprietary Peptides plus multiple supportive ingredients for next-level anti-aging support.

BIO SERUM FIRM contains the same high concentration of Human Growth Factors as BIO SERUM to support collagen, diminish the appearance of fine lines and wrinkles, and redefine the look of facial contours for a more youthful appearance. In addition, BIO SERUM FIRM includes the same percentage of Proprietary Peptides as MICRO SERUM to support collagen and elastin restoration and address the complex signs of aging, including firmness, elasticity, tone, and texture.

In a clinical study, subjects saw results within the first week of use. At Day 6, they said their skin felt smoother, more hydrated, tighter, and firmer. Additionally, over the next 8 weeks, subjects and study investigators continued to see changes in the signs of aging, including a significant improvement in firmness and elasticity, as well as the appearance of fine lines and wrinkles, skin tone, evenness, and brightness.

In Neocutis data analyses, the combined power of Human Growth Factors and Proprietary Peptides provided better results than each ingredient alone
Specifically, after 8 weeks, BIO SERUM FIRM provided greater improvements in:

• Skin firmness and elasticity vs both Growth Factors and Proprietary Peptides individually
• Appearance of fine lines and wrinkles and texture/smoothness vs Growth Factors alone

Key ingredients include high and low weight sodium hyaluronate to increase skin elasticity and seal in moisture, arginine for antioxidant protection, glycerin to boost hydration, acetyl glucosamine—an exfoliant that helps brighten skin, glutamine to support collagen production, and pullulan for skin-tightening support.
