- GHK-Cu (Copper Tripeptide)
- Binds to fibroblast receptors and upregulates TGF-beta, VEGF, and collagen synthesis pathways
- Fibroblast surface receptors; copper-dependent lysyl oxidase
- 8–12 weeks for measurable dermal thickness changes
- Sustained during consistent application; gradual return to baseline over months after cessation
- Static wrinkles, dermal thinning, photodamage, tissue repair, wound healing
- Rebuilds tissue structure; requires sustained application; effects are cumulative and structural rather than immediate
- Botox (Botulinum Toxin Type A)
- Cleaves SNAP-25 protein at the neuromuscular junction, blocking acetylcholine release and preventing muscle contraction
- SNAP-25 (synaptosomal-associated protein) at presynaptic nerve terminals
- 3–7 days for visible smoothing; peak effect at 14 days
- 3–6 months until nerve terminal regeneration restores muscle function
- Dynamic wrinkles (expression lines), hyperhidrosis, muscle spasticity
- Immediate and predictable; no effect on tissue quality or static wrinkles; purely neuromuscular
