Biomarker Analysis in Thailand’s Cosmetic Supply Chain

Biomarker analysis refers to the testing of specific “marker” compounds or active ingredients in cosmetic formulations to verify their identity, concentration, and stability. This is a critical quality assurance step that helps ensure products are authentic, safe, and effective throughout their lifecycle. Key roles of biomarker analysis include:

• Verifying Active Ingredients: Analytical testing confirms that a cosmetic product contains the claimed active ingredients (or botanical extracts) at the proper concentrations. By measuring marker compounds, manufacturers ensure consistency and potency in their formulations. For example, if a serum label advertises 10% vitamin C, biomarker analysis can verify that the actual content falls within an acceptable range—thereby substantiating the product’s claims and ensuring efficacy. This process authenticates herbal ingredients by matching their chemical fingerprint to reference standards.
• Detecting Adulteration: Biomarker assays help uncover any adulterants or banned substances that may have been illicitly added to enhance product performance. Advanced tests—such as those based on ELISA or HPLC-MS methods—can rapidly screen for hidden corticosteroids or other contaminants. Routine analysis ensures that only safe, permitted ingredients are present, thereby protecting consumers from products that contain misleading or hazardous components.
• Ensuring Product Stability:  Monitoring biomarkers over time is essential for stability testing. By periodically measuring the levels of key actives and potential degradation products, companies can verify that a cosmetic remains effective and safe up to its expiration date. Stability studies use biomarker data to detect changes in formulation—such as loss of potency or the formation of irritants—which helps in setting accurate shelf lives and proper storage conditions.

Robust biomarker analysis relies on several scientific techniques to identify and quantify ingredients with high precision. The most important analytical methods include:

• High-Performance Liquid Chromatography (HPLC): HPLC is considered a gold-standard technique for separating and quantifying components in a cosmetic sample. Manufacturers use HPLC to confirm concentrations of vitamins, herbal extracts, and preservatives against established standards. In some cases, HPLC is combined with Gas Chromatography (GC) for volatile or lipid-based markers.

• Mass Spectrometry (MS): Often paired with HPLC (i.e., LC-MS/MS) or GC (i.e., GC-MS), mass spectrometry identifies molecules based on their mass-to-charge ratio with exceptional sensitivity. This method is widely used for screening ingredients, verifying product authenticity, and detecting trace levels of potential contaminants such as steroids, hydroquinone, or heavy metals.

• Enzyme-Linked Immunosorbent Assay (ELISA): ELISA uses antibodies to selectively detect specific substances. It is a powerful tool for rapid screening of biological markers or small molecule adulterants in cosmetics. For example, commercial ELISA kits have been adapted to detect multiple corticosteroid adulterants in creams and serums.

• Advanced Techniques:  Additional methods—including spectroscopic techniques (Infrared, Raman, Near-Infrared), Nuclear Magnetic Resonance (NMR), and even DNA barcoding for herbal ingredients—provide comprehensive chemical fingerprinting. These techniques are useful for both routine verification and detailed confirmatory analysis.

Regulatory frameworks in Thailand and globally demand rigorous verification of cosmetic product quality. Compliance with the ASEAN Cosmetic Directive (ACD) is particularly important for Thai manufacturers. The ACD mandates that each product be safe, properly labeled, and manufactured only with approved or conditionally permitted ingredients. This means that the quantities of actives in the finished product must match what is declared on the label and fall within permitted limits.

Cosmetic companies are required to compile a Product Information File (PIF) that includes detailed data on formulations, test methods, and stability studies—all of which are supported by biomarker analysis. Additionally, adherence to Good Manufacturing Practices (GMP) and international standards such as ISO 22716 further underscores the need for robust analytical validation. In this context, thorough biomarker analysis is a key component of a comprehensive quality and safety assurance program.

Independent Quality Assurance Verifiers (IQAVs) are third-party organizations that provide an extra layer of oversight throughout the cosmetic supply chain by offering impartial verification of product quality. In the context of biomarker analysis, IQAVs play a pivotal role by:

• Enhancing Transparency and Trust: When a product label declares a specific percentage of an active ingredient, consumers expect that this claim is backed by rigorous testing. IQAVs verify these claims through independent biomarker analysis, ensuring that the actual content measured in the product falls within an accepted range of the label claim. This verification builds credibility and trust among consumers.
• Ensuring Efficacy and Safety: The effectiveness of a cosmetic product is directly related to the precise content of its active ingredients. IQAVs ensure that formulations perform as expected by independently confirming that the product’s biomarker levels are consistent with its claims. This oversight helps protect consumers by ensuring that products deliver their intended benefits safely.
• Market Differentiation: Brands that leverage independent verification can differentiate themselves in a competitive market. The involvement of an impartial verifier reassures consumers that the product’s label accurately reflects its formulation. This transparency can become a powerful marketing advantage.

A notable development in biomarker analysis is the launch of VISBIO—a new laboratory dedicated to advanced biomarker testing for the cosmetic industry. VISBIO now offers a formal certification trademark that indicates a product has successfully undergone its rigorous biomarker testing process. It is important to note that while VISBIO’s certification trademark is a recognized mark of quality, VISBIO itself is not a certification body; rather, the trademark serves as a trusted indicator that the product’s active ingredient content has been independently verified.

• Comprehensive Biomarker Testing Services: VISBIO specializes in quantitatively analyzing key active ingredients in cosmetic products. By employing advanced techniques such as HPLC, mass spectrometry, and ELISA, VISBIO verifies that the actual concentrations of active ingredients align with those declared on product labels. This independent data confirms that the product content falls within an acceptable range, supporting its performance and efficacy.
• Supporting Transparency and Quality Assurance: Through its formal certification trademark, VISBIO signals to manufacturers, retailers, and consumers that a product has met its stringent biomarker testing criteria. This trademark is a mark of transparency, ensuring that the active ingredient levels are accurately represented. It bridges the gap between marketing claims and scientific verification, thereby fostering consumer trust.
• Industry Impact:  By providing unbiased, scientifically robust testing, VISBIO exemplifies the emerging role of IQAVs in the cosmetic supply chain. Its formal certification trademark helps brands differentiate themselves as quality-focused and reliable. With VISBIO’s independent verification, manufacturers can confidently display that their product labels accurately reflect the tested active ingredient content, reinforcing both regulatory compliance and consumer confidence.

Biomarker analysis is indispensable for ensuring that cosmetic products are authentic, safe, and effective. Advanced analytical techniques such as HPLC, mass spectrometry, and ELISA provide the scientific backbone for verifying that active ingredient levels match label claims. Regulatory expectations and industry standards require such verification as part of a comprehensive quality assurance program.

Independent Quality Assurance Verifiers (IQAVs) play a central role by offering third-party oversight. Their work—exemplified by emerging laboratories like VISBIO—ensures that when a product label declares a specific percentage of an active ingredient, the actual tested content falls within an accepted range. VISBIO’s formal certification trademark serves as a trusted indicator that the product has met stringent biomarker testing criteria, even though VISBIO is not a certification body. This independent verification is essential for building consumer trust and enhancing transparency in Thailand’s cosmetic supply chain, ultimately supporting a more reliable and consumer-friendly marketplace.

In conclusion, incorporating biomarker verification by IQAVs such as VISBIO ensures that cosmetic product labeling accurately reflects tested results, directly impacting product efficacy and consumer confidence in the cosmetics market.
