Cosmetics Efficacy Evaluation: A Compliance Guide for Brands

I. What Cosmetics Efficacy Evaluation Actually Evaluates

Put simply, cosmetics efficacy evaluation uses scientific methods to prove that the efficacy you claim is real. If you claim a cream moisturises, you need moisturisation data. If you claim brightening, you need a brightening efficacy evaluation report. If you claim anti-wrinkle, you need evidence there too. Under current standards, except for a few exempt cases, the registrant or filer is responsible for efficacy claims and must upload a summary of the supporting basis to the platform designated by the National Medical Products Administration. In other words, claims are not guesswork — they must be documented and traceable.

For brands, the earlier this is planned the easier it is. Building it into the project stage rather than remembering to add data once the packaging is already printed avoids a great deal of rework and waste.

II. Four Common Cosmetics Efficacy Evaluation Methods

The standards set out four evaluation routes. Brands can combine them flexibly based on positioning and budget rather than committing to one:

1. Human Efficacy Trials

This is the most persuasive approach, substantiating efficacy through measurement on volunteer skin. High-interest claims such as brightening, anti-wrinkle and sun protection often must rely on human trials. The drawbacks are long timelines and high cost — usually weeks to months — plus ethics review and volunteer recruitment.

2. Laboratory Tests

Instruments are used to test on ex vivo skin or samples — a corneometer to measure skin moisture for moisturisation, or instrument-based quantification of wrinkle changes to support anti-wrinkle judgements. More cost-effective than human trials, and well suited to quickly confirming direction during formulation R&D.

3. Literature or Research Data

Citing published domestic and international literature, patents and research reports as the basis. Suitable for claims where solid scientific consensus already exists, such as the mechanism of action of certain classic ingredients. Relevance matters — unrelated papers cannot be used to pad the file.

4. Consumer Use Tests

Real users apply the product over a period and report their experience, with subjective ratings collected through questionnaires. Useful for experience-led claims such as a fresh feel, gentle non-irritation and easy absorption, and a source of testimonial material for product pages.

III. Different Claims, Different Evaluation Requirements

This is where brands most often go wrong — assuming one report covers everything. In reality, different claim words carry very different evaluation thresholds:

• Moisturising: a basic claim that can be substantiated through laboratory testing or consumer testing, relatively easy, and the standard claim for most creams and lotions.
• Brightening and spot fading: special cosmetics requiring a special cosmetics registration certificate, with strict efficacy evaluation requirements — normally human trials — and best landed alongside a three-certificate brightening system (registration certificate plus patents plus human testing).
• Anti-wrinkle and firming: high-interest claims that generally require human efficacy trials, supported by both subjective scoring and objective instrument measurements.
• Sun protection: special cosmetics. SPF and PA values must be measured per standard methods, written truthfully on the label, and cannot be inflated.
• Acne care: products claiming acne care must be evaluated per the standards and cannot rely on the ingredient list to imply the effect.

IV. How Brands and Manufacturers Prepare the Evaluation Report

To produce an evaluation report that holds up, these steps work well:

• Lock the claim words first. Decide whether you are claiming moisturising, brightening or anti-wrinkle — each word maps to a set of evidence, so do not overreach.
• Choose the right evaluation route. Work with R&D and regulatory colleagues to judge which method is most economical and most in line with regulatory expectations; for special claims, do not skip human trials.
• Keep the raw data. Test protocols, volunteer information, test reports and statistical results should all be archived and retrievable at any time, so spot checks can be answered quickly.
• Upload the claim summary. Completing the upload of the efficacy claim basis summary on the designated official platform is what closes the loop.

For manufacturers, an ODM partner able to support formulation R&D, special registration and efficacy evaluation under one roof saves considerable time on communication and repeated hand-offs. DEVA INTERNATIONAL's Changbai Series follows exactly this three-certificate brightening route, running from R&D through human testing in one process. If you are looking for such a partner, see our cosmetics ODM services and brightening special registration offering.

V. These Compliance Lines Cannot Be Crossed

• Absolute terms: phrases like most effective or number one brand are essentially landmines in cosmetics claims, and must be avoided on both product pages and packaging.
• Implied medical action: claims such as treatment, anti-inflammatory or scar repair are off limits — cosmetics are not medicines, and crossing that line carries high risk.
• Unsupported claims: writing an efficacy claim without evaluation data is a focus of regulatory spot checks and a frequent source of competitor complaints.
• Borrowed reports: one report corresponds to one product. Borrowing, altering or misapplying a report is a violation, and the consequences are serious once confirmed.

VI. Questions Brands Ask Often

Q: With a limited budget, can a small brand skip human trials?

A: It depends on the claim. Basic claims such as moisturising and cleansing can rely on laboratory tests or consumer testing; but for special cosmetics like brightening and sun protection, human trials are a hard requirement. With a tight budget, focus on one core claim and make the evidence solid.

Q: Can the manufacturer's report be handed straight to the brand?

A: The report must reflect the real commissioning relationship and the specific product, so it cannot simply be reused. A proper ODM factory issues evaluation materials for the product actually commissioned, and only then are they valid in the brand's hands.

Q: How long does one efficacy evaluation remain valid?

A: There is no single expiry period, but after a major change to formula or process the original basis may no longer hold and re-evaluation is needed. Keeping evaluation materials in the product file and updating them with each version is the practical approach.
