- In vitro melanocyte culture
- 10–100 nM (10–100 µg/mL)
- 48–72 hours
- Sustained with repeated dosing
- No keratinocyte or immune cell interaction
- Ex vivo human skin explant
- 50–200 µg/cm² topical or 0.1–0.5 mg subdermal
- 72–96 hours
- 10–14 days post-treatment
- Limited metabolic activity after 96 hours
- In vivo rodent (subcutaneous)
- 0.5–2.0 mg/kg
- 5–7 days
- 3–4 weeks
- Species differences in MC1R structure
- Human volunteer (research setting)
- 0.5–1.0 mg subcutaneous (single dose)
- 2–3 weeks
- Ethical and regulatory constraints
- Comparison to UV exposure (MED protocol)
- 1.5–3.0 MED over 10 days
- 7–10 days
- 4–6 weeks
- Requires cumulative UV damage to trigger
- Professional Assessment
- MT2 produces faster, more consistent melanogenesis across all models except where MC1R polymorphisms (red hair phenotype) reduce receptor responsiveness. UV-independent activation eliminates confounding variables from DNA damage response.
