Molecular Synergy is rooted in Dr. Diamond's multi-modality approach to aesthetics. In his practice, meaningful rejuvenation is achieved by treating multiple biological pathways simultaneously rather than relying on a single treatment. This same philosophy guides every Metacine formula.

Rather than formulating around a single hero ingredient, Metacine combines complementary bioactive technologies selected not only for their individual activity, but for how they work together to support the skin's natural repair & rejuvenation processes. Molecular synergy is a more comprehensive & effective approach as synergy amplifies results.

This philosophy is built on core scientific principles that guide every formula:

SKIN AGING HAPPENS THROUGH MULTIPLE BIOLOGICAL CHANGES
Skin aging is driven by multiple biological changes occurring at once, including collagen decline, hydration loss, barrier weakening, oxidative stress & slower cellular renewal. Addressing only one pathway limits results. By supporting multiple biological processes simultaneously, formulas can deliver a more comprehensive approach to visible skin rejuvenation.

MOLECULAR SIZE DETERMINES PERFORMANCE
Molecular size & structure influence how ingredients interact with the skin. By combining multiple molecular weights & complementary molecular structures, ingredients can work across different layers of the skin, supporting more complete hydration, repair & visible performance.

SYNERGY AMPLIFIES RESULTS
Growth factors, signaling peptides, antioxidants, next-generation retinoids & advanced hydrators are intentionally combined through complementary biological pathways. Working together, these technologies amplify one another's performance, supporting collagen signaling, barrier integrity, hydration & visible skin renewal beyond what any single ingredient can achieve alone.

THE BIOMIMETIC DIFFERENCE
Whenever possible, Metacine formulates with biomimetic ingredients engineered to closely replicate molecules naturally found in healthy skin. Because they are structurally familiar, the skin can recognize & respond to them more efficiently, helping optimize compatibility while supporting hydration, barrier function, collagen integrity & overall skin resilience.

Growth factors are naturally occurring proteins that act as the cellular messengers of the human body, helping coordinate essential processes that support renewal, repair & regeneration.

Within the skin, growth factors are released by cells, bind to receptors & activate pathways that support collagen, elastin & extracellular matrix production, helping maintain firmer, more resilient, youthful-looking skin.

As we age, growth factor activity naturally declines & the skin’s communication network becomes less efficient, contributing to visible changes in firmness, elasticity, texture & radiance. 

Growth factors are central to Dr. Diamond's regenerative approach to aesthetic medicine. His signature in-office InstaFacial® harnesses the power of platelet-rich plasma (PRP), a treatment rich in naturally occurring growth factors that help support the skin's natural repair & rejuvenation processes. At Dr. Diamond's Metacine, growth factors are engineered in a lab to be 100% biocompatible to the human body, thus reintroducing these essential messengers back to the skin to harness their innate ability to support repair & rejuvenation as well as ensure safety, consistency, potency & shelf stability.

InstaFacial® Plasma features five different types of bioengineered, human-identical growth factors: Insulin-Like Growth Factor-1 (IGF-1), Epidermal Growth Factor (EGF), Vascular Endothelial Growth Factor (VEGF), Fibroblast Growth Factor Acidic (FGF-1), & Fibroblast Growth Factor Basic (FGF-2). Together, they are designed to mimic the diverse growth factor profile naturally found in PRP. Each supports a different aspect of skin rejuvenation from cellular renewal & collagen production to microvascular support & repair, creating a more comprehensive signaling network than any single growth factor alone.

Peptides are widely used throughout Metacine formulas for their ability to support the skin's natural communication network. These short chains of amino acids deliver targeted biological signals that help support collagen production, cellular renewal, barrier function & overall skin resilience.

Metacine formulates with both individual bioactive peptides & advanced signaling peptides, including Copper Tripeptide-1, Myristoyl Nonapeptide-3, Palmitoyl Tripeptide-38, Palmitoyl Tetrapeptide-7, & human-identical Epidermal Growth Factor (sh-Oligopeptide-1), which are selected not only for their individual activity, but for how they work together within our philosophy of Molecular Synergy.

Beyond individual peptides, Metacine engineers proprietary peptide networks that recreate complex biological signaling. Our Biomimetic Collagen Matrix in InstaFacial® Infusion combines multiple human-identical microcollagen peptides (sh-Polypeptide-121, sh-Polypeptide-123, sr-sh-Polypeptide-69 Dipeptide-19) to help support the skin's extracellular matrix & collagen architecture.

Similarly, EyeLift's Bioremodeling Peptide Complex is a proprietary peptide network that features bioengineered, human-identical microcollagen (sh-Polypeptide-47) along with signaling peptides like Tripeptide-1, Hexapeptide-9, a novel, patented HyaluPeptide Hybrid (a collagen peptide, hyaluronic acid complex) & Caprooyl Tetrapeptide-3, a growth factor-derived lipopeptide. Working through complementary biological pathways, this advanced complex supports the synthesis of collagen, elastin & hyaluronic acid while helping inhibit matrix metalloproteinases (MMPs), enzymes responsible for collagen degradation. It also helps support the dermal-epidermal junction (DEJ), reinforcing the structural connection between the epidermis and dermis for firmer, more resilient-looking skin. The result is a comprehensive system designed to visibly contour, lift & revitalize the skin around the upper & lower eye area immediately & over time.

Working alongside growth factors, retinoids, antioxidants & advanced hydrators, these peptide technologies amplify cellular communication through complementary biological pathways, creating a more comprehensive approach to visible skin rejuvenation than any single ingredient alone.
