What's the best peptide stack for skin improvement and anti-aging?

The premier skin stack combines GHK-Cu (for collagen synthesis and wound healing), Epithalon (for cellular regeneration), and Matrixyl (for wrinkle reduction). GHK-Cu increases collagen type I by up to 70%, while Epithalon supports telomere health and cellular turnover. Studies in <a href='https://pubmed.ncbi.nlm.nih.gov/31634936/' target='_blank' rel='noopener'>Journal of Cosmetic Dermatology</a> demonstrate visible improvements in skin texture, firmness, and pigmentation with this combination.
