Field Notes

Editorial briefs from the atelier.

Chemistry-literate notes for cosmetic, dermatology, hair-scalp, and mesotherapy formulators working with copper-bound peptide actives. Each Note is written to be read at the bench, in the time it takes to weigh out a sample.

The Field Notes catalogue grows slowly on purpose. Each Note is written from a working copper-peptide question we get from formulators — published when the topic is concrete enough to be useful at the bench, not before. The next Notes in the queue cover reading a Cu-peptide UV-Vis spectrum, chelator audits for cosmetic preservative systems, and scoping a custom Cu-peptide pilot.
