- GHK-Cu
- Upregulates TGF-beta, activates fibroblast collagen I/III synthesis
- Direct. 70% increase in fibroblast collagen production (in vitro)
- Skin structure, wound healing
- Human fibroblast studies, published in Journal of Inflammation
- Core component. Strongest evidence for collagen stimulation
- Thymosin Beta-4
- Promotes actin polymerization, VEGF-mediated angiogenesis
- Indirect. Supports nutrient delivery to dermis via capillary formation
- Wound healing, reduced fibrosis, tissue repair
- Animal wound healing models, clinical observations in soft tissue injury
- Essential for recovery. Angiogenic properties support dermal health
- BPC-157
- VEGF receptor modulation, tendon-bone healing acceleration
- Indirect. Supports connective tissue repair including dermal collagen
- Tendon/ligament repair, angiogenesis, anti-inflammatory
- Rat tendon healing studies, gastric protection models
- Strong recovery support. Collagen matrix repair extends to skin
- Thymalin
- Immunomodulation via thymic peptide signaling
- None direct. Reduces systemic inflammation affecting collagen degradation
- Immune regulation, chronic inflammation reduction
- Limited human trials, primarily Eastern European research
- Optional adjunct. Benefits are systemic rather than skin-specific
