- Day 1–3
- Immediate glow, tightening sensation
- Peptide binds to integrin receptors, begins upregulating gene transcription for collagen and MMPs
- Gene activation ≠ protein synthesis. There's a 7–14 day lag before translated proteins appear
- Day 4–7
- Visible reduction in fine lines
- Increased aquaporin-3 expression improves epidermal hydration; minor IL-6 suppression reduces redness
- Hydration and inflammation changes are real but temporary unless collagen remodelling follows
- Week 1 Overall
- Dramatic transformation
- Cellular priming. Fibroblast proliferation increases, damaged collagen begins clearing, new collagen mRNA rises
- The visible outcome (new collagen deposition) doesn't manifest until weeks 3–8; week one is invisible preparation
- Placebo Perception
- 'My skin looks better already'
- Confirmation bias + improved skincare routine discipline
- Starting any new protocol increases attention to skincare habits. Moisturising more consistently, drinking more water, avoiding irritants
