- Thymosin Beta-4 (TB-4)
- Promotes keratinocyte migration, reduces mast cell degranulation, upregulates IL-10
- IL-1beta, TNF-alpha, IL-10
- 38% reduction in dermal inflammation scores in murine contact dermatitis model
- 7–14 days for erythema reduction
- Best for acute flares and mast cell stabilization. Works fastest on visible inflammation
- GHK-Cu (Copper Peptide)
- Stimulates filaggrin and ceramide synthesis, enhances collagen crosslinking
- Indirect anti-inflammatory via barrier restoration
- 34% increase in stratum corneum hydration, 29% reduction in TEWL over 16 weeks
- 4–6 weeks for barrier restoration
- Optimal for chronic barrier dysfunction and atopic dermatitis. Long-term repair rather than symptom suppression
- KPV (Lysine-Proline-Valine)
- Inhibits NF-kappaB activation, blocks inflammatory gene transcription
- IL-6, IL-8, TNF-alpha, IL-4, IL-13
- 47% reduction in EASI scores over 12 weeks in Phase 2 trial (topical gel, twice daily)
- 2–3 weeks for pruritus reduction
- Strongest evidence for sustained efficacy without tachyphylaxis. Selective immune modulation preserves long-term response
