- The table below contrasts three evidence-based peptide combinations used in published dermal studies. Each stack targets different primary outcomes. Choose based on the specific dermal pathway you're investigating.
- Collagen Restoration Stack
- GHK-Cu + Matrixyl 3000
- TGF-beta upregulation + procollagen I/III gene expression
- 28–35% increase in dermal density (ultrasound), 18–22% reduction in wrinkle depth (profilometry)
- Best supported by clinical evidence. Addresses photoaging through complementary collagen pathways without mechanistic overlap
- Pigmentation Modulation Stack
- KPV + Alpha-MSH analogue
- NF-kB inhibition + melanocyte receptor modulation
- 40–48% reduction in hyperpigmented lesion size (spectrophotometry), 15–20% improvement in melanin distribution uniformity
- Strongest evidence for post-inflammatory hyperpigmentation. Limited data on melasma or genetic pigmentation disorders
- Barrier Function Stack
- Cartalax Peptide + ceramide precursors
- Tight junction protein synthesis + lipid lamellae organisation
- 52% improvement in transepidermal water loss (TEWL), 38% increase in stratum corneum hydration (corneometry)
- Critical for compromised barrier states (rosacea, atopic dermatitis) but shows minimal benefit in healthy skin
