INCI Teardown: How to Read a Luxury Vitamin C Serum Label With a Chemist’s Eye

The Clinical Hook A luxury vitamin C serum label is a strange document: it promises radiance in large type and then, in small type, tells you almost everything you actually need to know.

Glass Skin Without a Ten-Step Routine: Refraction, Hydration and Pore Appearance

Caprylic/capric triglyceride (MCT oil, GTCC) emollient oil texture for skin barrier care

The Clinical Hook Open the specification sheet of almost any modern serum, cleansing oil, or “dry-touch” moisturizer and you will meet caprylic/capric triglyceride — the quiet workhorse emollient of contemporary formulation. Then open a supplier catalogue and the same molecule starts answering to other names: MCT oil, GTCC, CCTG, fractionated coconut oil. The nomenclature suggests
