> **Key Takeaway**: Native hydrophilic oligopeptides cannot penetrate the stratum corneum or dissolve evenly in lipid gloss bases. Cosmetic developers must utilize N-terminal lipidation (e.g., Palmitoyl Tripeptide-1) or nanoemulsion carriers to achieve both active stability and high optical shine.

> **Pro Tip**: Always incorporate bioactive peptides during the cool-down phase of gloss manufacturing ($T < 40^\circ\text{C}$). Subjecting peptides to bulk wax heating ($75–85^\circ\text{C}$) induces irreversible thermal denaturation, peptide cleavage, or color alteration.
