Product ID
Product ID is a unique identifier assigned to each cosmetic or skincare ingredient, helping brands, formulators and shoppers track exactly what is used in a product.
How it works in skincare
In the beauty industry, a Product ID (often shown as a CAS number, INCI name reference or internal code) allows precise identification of an ingredient so that its concentration, purity and sourcing can be verified. It ensures consistency between batches and helps UK consumers and regulators understand exactly which raw material has been chosen for a cream, serum or lipstick.

Where it comes from
Product IDs are not derived from nature; they are standardised reference codes created by regulatory bodies, suppliers and manufacturers to catalogue both naturally sourced and synthetic cosmetic ingredients.
