Skin / Anti-Aging Research Program

Educational overview for skin / anti-aging research program.

Research overview

Research overview compiled from publicly available abstracts and reviews. Quality of evidence varies — some peptides have only preclinical data.

All 3 peptides in this category

Ranked by evidence quality: strongest human evidence first, preclinical and anecdotal last.

• GHK-CuLimited human evidence

  Copper tripeptide studied in dermatology for skin remodeling and wound contexts. Topical formulations are widely used in cosmetics.

• Argireline (Acetyl Hexapeptide-8)Limited human evidence

  Synthetic hexapeptide (Glu-Glu-Met-Gln-Arg-Arg) marketed as a topical 'botox alternative.' Theoretically interferes with SNARE complex formation, reducing neurotransmitter release at neuromuscular junctions. Topical formulations are widely sold in cosmetics. Effect size is modest at best in published trials.

• Melanotan IILimited human evidence

  Synthetic analog of α-melanocyte-stimulating hormone (α-MSH). Binds melanocortin receptors (notably MC1R for tanning and MC4R for sexual function). Originally researched for therapeutic skin pigmentation; abandoned in clinical development. Sold heavily as a grey-market 'tanning peptide.' Significant safety concerns — Class A action by some regulators.

Lifestyle suggestions

Foundational lifestyle factors (sleep, nutrition, training, stress) often outperform any single intervention in published research.

Lifestyle factors (sleep, nutrition, training, stress) are foundational. SmartPeptide does not provide exact dosing instructions for any peptide.
