- Topical Solution (Bacteriostatic Water)
- 0.5–2.0 mg/mL
- 60–75% dermal penetration within 45 minutes
- Stable for 4–6 hours on scalp before oxidation
- Gold standard for research. Predictable dosing, minimal degradation
- Topical Gel Formulation (Carbomer Base)
- 1.0–3.0 mg/mL
- 40–55% dermal penetration over 2 hours
- Stable for 8–12 hours due to reduced oxygen exposure
- Better for sustained release but lower peak bioavailability
- Microneedling + Topical Application
- 0.5–1.0 mg/mL
- 85–90% penetration through microchannels
- Immediate absorption. Minimal surface oxidation
- Highest absorption but requires trained application and aseptic technique
- Liposomal Encapsulation
- 0.3–1.0 mg/mL
- 70–80% penetration with delayed release
- Stable for 12–24 hours in lipid bilayer
- Protects peptide from oxidation but adds formulation complexity
