Platinum Smooth

Precision where lines begin to show.

Fine lines aren't a one-dimensional concern. That's why Pt78 isn't built around a single peptide.

This targeted serum combines Acetyl Hexapeptide-8, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7 and Acetyl Tetrapeptide-17 in a multi-peptide approach designed to support smoother, firmer and more refined-looking skin.

Glycerin, aloe and olive-derived squalane complement the peptide system with hydration and conditioning, while colloidal platinum connects the formula to the elemental philosophy at the heart of Periodic Method.

Lightweight and easy to layer, Pt78 is designed to become the targeted fine-line treatment within your daily Method.

The result: skin that looks smoother, more refined and visibly refreshed with continued use.
