- Melanotan-1 (afamelanotide implant)
- 7–10 days
- 60+ days per implant
- No. Stimulates melanin independent of UV
- Predominantly eumelanin
- FDA-approved for EPP only
- Gold standard for controlled photoprotection research. Implant delivery eliminates user dosing error
- Melanotan-1 (research-grade injectable)
- 7–14 days
- Requires ongoing dosing 2–3x weekly
- No. Direct MC1R agonism
- Not FDA-approved; research use only
- Same biological mechanism as implant but lacks dosing precision and batch-to-batch quality verification
- Natural tanning (UV-induced)
- Immediate erythema; pigmentation 48–72 hours
- Fades over weeks without re-exposure
- Yes. UV triggers keratinocyte α-MSH release
- Mix of eumelanin and pheomelanin (ratio varies by genetics)
- N/A
- Baseline photoprotection comes with cumulative DNA damage. Not a protective strategy
- Topical sunscreen (broad-spectrum SPF 30+)
- Immediate upon application
- 2 hours or until removed by water/sweat
- No
- None. Physical/chemical UV filtration only
- FDA-regulated as OTC drug
- First-line photoprotection. Melanotan-1 does not replace sunscreen but may reduce burn threshold
- Oral photoprotective supplements (polypodium leucotomos, astaxanthin)
- 4–8 weeks
- Requires daily intake
- None. Antioxidant mechanism, not melanogenesis
- Dietary supplement (minimal regulation)
- Marginal photoprotection at best; clinical evidence is weak and inconsistent
