- Oligopeptide-68
- Competitive tyrosinase inhibition at enzyme active site
- 2–10%
- 8–12 weeks for visible reduction
- Melasma, post-inflammatory hyperpigmentation, UV-induced sunspots
- Most clinically validated option. Combine with SPF 50+ for maximum efficacy
- Nonapeptide-1 (Melanostatin-5)
- Alpha-MSH receptor antagonist. Blocks melanocyte activation signal
- 50–200 ppm (0.005–0.02%)
- 10–14 weeks for measurable lightening
- Prevention-focused protocols, sensitive skin unable to tolerate hydroquinone
- Works best as a maintenance agent after initial correction with stronger actives
- Acetyl Hexapeptide-8
- Disrupts SNARE complex formation in melanocyte vesicle release
- 5–10%
- 12–16 weeks for observable change
- Fine-line reduction with secondary brightening benefit
- Weaker pigmentation effect than tyrosinase inhibitors. Better suited for dual anti-aging + brightening goals
- Undecylenoyl Phenylalanine
- Inhibits tyrosinase and peroxidase enzymes simultaneously
- 0.5–2%
- 8–12 weeks
- Stubborn melasma resistant to single-target inhibitors
- Often paired with niacinamide for synergistic melanin transfer inhibition
