Skincare Testing & Documentation Guide

Last reviewed: August 2026. Testing and documents should be planned from the final formula, packaging, claims and target market—not collected after commercial decisions are fixed. This is a practical planning guide, not legal advice.

Why this matters before launch

Decisions in this area affect formula, claims, labeling, technical documentation and the selected country route. Review them before commercial artwork or production is locked.

Key concepts

Safety substantiation

A structured rationale and supporting evidence that the finished product is safe for intended use.

Stability and compatibility

Evidence that the formula remains suitable through shelf life and works with its selected packaging.

Product file

A controlled set of formula, quality, testing, label and claim records.

How to manage the work

1. Define Product
2. Set Evidence Plan
3. Collect Technical Data
4. Run Applicable Tests
5. Build Product File
6. Maintain Updates

What the factory needs and does

The factory supplies the controlled technical evidence required for review.

• Provide formula, specifications, batch and manufacturing data.
• Coordinate appropriate stability, microbiological and compatibility support.
• Maintain raw-material, test and change-control records.

What the brand needs and does

The brand owns market position, final claims and market-facing approvals.

• Define market, product claims and testing objective.
• Approve protocol scope and final evidence use.
• Maintain document ownership with the responsible local party.
