- Hydrolysed collagen peptides (Type I/III)
- Provides amino acids (Gly-Pro-Hyp) for fibroblast collagen synthesis
- 2.5g/day × 24 weeks: 15% elasticity increase, 11% cellulite reduction (Journal of Medicinal Food)
- Oral. Survives digestion, reaches dermis via systemic circulation
- Most robust evidence for structural improvement; cost-effective; requires consistent long-term use (12+ weeks)
- GHK-Cu (copper peptide)
- Activates TGF-β pathway, upregulates procollagen mRNA, inhibits collagen-degrading enzymes
- 1% topical × 16 weeks: 18% dermal density increase, 22% cellulite severity reduction (Int. J. Cosmetic Science)
- Topical. Molecular weight 340 Da allows partial dermal penetration
- Strong signalling peptide; penetration depends on formulation; copper ions provide additional cross-linking benefit
- Palmitoyl pentapeptide-4 (Matrixyl)
- Mimics procollagen sequence, tricks fibroblasts into accelerating synthesis
- 3% topical × 12 weeks: 13% dermal density increase, 19% dimple depth reduction (J. Cosmetic & Laser Therapy)
- Topical. Lipophilic structure aids stratum corneum crossing
- Effective for localised application; results plateau after 12–16 weeks; often combined with retinoids in formulations
- Acetyl hexapeptide-8 (Argireline)
- Inhibits SNARE complex, reduces muscle contraction
- No published data on cellulite-specific outcomes; mechanism targets expression lines, not dermal structure
- Topical. Molecular weight ~888 Da, limited deep penetration
- Mechanism unrelated to cellulite pathology; marketed for wrinkles, not connective tissue remodelling
- Generic 'cellulite peptide complexes'
- Unspecified amino acid blends, often with caffeine or retinol
- Marketing claims rarely cite peer-reviewed trials; ingredient concentrations undisclosed
- Variable. Formulation-dependent
- Insufficient data to assess efficacy; 'peptide complex' is not a standardised term; avoid products without named active compounds
