In the modern cosmetics industry, consumers are interested not only in ingredients and manufacturing technology but also in whether performance claims are supported by scientific data. At the same time, cosmetic businesses are responsible for product safety, quality, and claimed performance, while advertising content should remain consistent with supporting documentation and applicable ASEAN cosmetic-claims guidance. As a result, demonstrating product performance in human volunteers is increasingly important in product and brand-development strategies.

The Academy of Medical Sciences, Vietnam provides Human Efficacy Study services to generate objective scientific evidence for cosmetic performance claims. Studies are designed using evidence-based principles and appropriate clinical-research, dermatological-assessment, and statistical methods to produce data that are scientifically useful and practically relevant.

This service may be suitable for businesses that:

• Are developing a new cosmetic product.
• Want to support product-performance claims with scientific data.
• Are preparing materials for product advertising and communications.
• Are developing or updating a Product Information File (PIF).
• Want to strengthen brand credibility and competitive positioning.
• Are preparing to enter markets that place greater emphasis on scientific evidence.

Depending on product characteristics, the Academy of Medical Sciences, Vietnam can design studies to assess a range of cosmetic performance outcomes, including:

Skin Care

• Moisturization.
• Reduction in transepidermal water loss (TEWL).
• Skin softness.
• Improvement in skin elasticity.
• Improvement in skin firmness.
• Reduction in the appearance of wrinkles.
• Improvement in skin brightness.
• Support for reducing the appearance of hyperpigmentation, where appropriate to the cosmetic claim.
• Improvement in skin-tone evenness.
• Reduction in the appearance or measured size of pores.
• Sebum control.
• Support for improving acne-prone skin appearance, where appropriate to the cosmetic claim.
• Soothing of sensitive skin.
• Support for skin-barrier function.

Hair and Scalp Care

• Reduction in hair breakage or shedding, depending on the study objective.
• Improvement in hair strength.
• Improvement in shine and smoothness.
• Reduction in dandruff.
• Reduction in scalp oiliness.
• Improvement in dry or itchy scalp condition.

Sun Protection

• Assessment of skin-protection performance according to the study objective.
• Assessment of the persistence of performance after a defined period of use.

Consumer Perception Assessment

• User satisfaction.
• Skin feel or product-use experience.
• Texture and absorption.
• Fragrance.
• Overall consumer acceptance.

Depending on the study objective, outcomes may be assessed using one or a combination of methods:

• Clinical assessment by qualified professionals.
• Skin- and hair-function measurement devices.
• Standardized photography before and after product use.
• Image analysis using specialized software.
• User self-assessment questionnaires.
• Statistical analysis to determine the magnitude of change and the scientific relevance of the results.

Each study uses clearly defined eligibility criteria, standardized data-collection procedures, and quality-control processes designed to support objectivity, accuracy, and traceability.

Human efficacy studies can provide several types of value for a business:

• Generate direct scientific evidence on the actual product.
• Strengthen the scientific basis for product-performance claims.
• Support evidence-based advertising and communication materials.
• Add scientific data to the Product Information File (PIF).
• Strengthen brand credibility with consumers, professionals, and partners.
• Support research and development (R&D), formulation improvement, and optimization of product performance.
• Support competitiveness in domestic and international markets.

The Academy of Medical Sciences, Vietnam conducts studies using a standardized process designed to support scientific quality and data transparency.

1. Define the product-performance claims and study objectives.
2. Design the study protocol and assessment criteria.
3. Recruit volunteers according to the study criteria.
4. Conduct the study and monitor product use.
5. Collect and quality-control the data.
6. Perform statistical analysis and interpret the results.
7. Complete the scientific report and deliver the agreed research data to the business.

We do more than conduct a single study; we help businesses build a scientific evidence framework that can support the product throughout its lifecycle.

The Academy of Medical Sciences, Vietnam provides:

• Study design based on evidence-based principles.
• A multidisciplinary team with expertise relevant to dermatology, clinical medicine, pharmacy, and biostatistics.
• Access to a volunteer network that can support diverse study criteria.
• Professional data-management and statistical-analysis processes.
• Transparent scientific reporting with potential application in product dossiers, communications, and market-development activities.

Each human efficacy study conducted by the Academy of Medical Sciences, Vietnam is intended to generate objective, reliable, and practically useful scientific evidence. We support businesses from defining the research objective and conducting the study in volunteers through data analysis and responsible use of the findings, while recognizing that results may be positive, neutral, mixed, or unfavorable and that commercial claims must remain consistent with the evidence and applicable regulations.
