BIO SERUM FIRM is a sophisticated combination of both Human Growth Factors (0.1%) and Proprietary Peptides (0.02%) plus multiple supportive ingredients for next-level anti-aging support.

BIO SERUM FIRM contains the same high concentration of Human Growth Factors (0.1%) 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 (0.02%) as MICRO SERUM to support collagen and elastin restoration and address the complex signs of aging, including firmness, elasticity, tone, and texture.

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.
