COSMETIC EFFICACY STUDIES TO SUBSTANTIATE COSMETIC PRODUCT CLAIMS
At AITEX, we carry out cosmetic efficacy studies designed to substantiate cosmetic product claims objectively and on a sound scientific basis. Our tests make it possible to validate claims relating to moisturisation, anti-wrinkle action, firmness, elasticity, soothing effect, sun protection, sebum regulation, depigmenting action and other functional properties, using instrumental, clinical and consumer perception methodologies.
WHAT ARE COSMETIC EFFICACY STUDIES?
Cosmetic efficacy studies make it possible to demonstrate the benefits of a product objectively and on a sound scientific basis, and to validate the claims communicated to consumers.
Through instrumental tests, clinical assessments and consumer studies, it is possible to substantiate properties such as moisturisation, firmness, wrinkle reduction, soothing effect and sun protection.
COSMETIC CLAIMS
Cosmetic claims are the statements that communicate the benefits and properties of a product to consumers. To be used lawfully and transparently, they must be supported by objective and scientifically demonstrable evidence.
At AITEX, we carry out tests tailored to different types of cosmetic claims, providing scientific evidence that supports commercial communication and compliance with applicable regulations. We generate objective evidence for the validation of cosmetic claims, supporting product positioning and differentiation.

Deodorant and antiperspirant efficacy
The efficacy of products designed to control body odour and perspiration is essential to consumer perception. At AITEX, we develop specific studies to assess and support the main claims for deodorants and antiperspirants, using methodologies tailored to the needs of each product.
Deodorant efficacy (Sniff Test)
The Sniff Test assesses the deodorant efficacy of a product through olfactory evaluation by a panel of expert assessors. Body odour intensity is analysed in volunteers by comparing an untreated armpit (control) with one to which the deodorant has been applied.
Participants use the product beforehand to avoid interference and carry out their usual daily activities during the study. Assessments are performed at different time intervals, making it possible to analyse both malodour reduction and the duration of the deodorant effect.
Odour intensity is rated on a defined scale, producing reproducible results. This test provides robust support for claims relating to the efficacy and duration of the deodorant effect.
Antiperspirant efficacy
The antiperspirant efficacy study aims to assess the ability of a product to reduce sweat production. The test is carried out on volunteers under controlled conditions, using specific methodologies to quantify the amount of sweat produced before and after product application.
Throughout the study, standardised protocols are applied to ensure the reproducibility and reliability of the results, allowing product performance to be compared objectively. This type of measurement is essential to ensure the validity of the data obtained.
The results provide quantifiable proof of antiperspirant efficacy, forming a solid basis for substantiating this type of claim. It is a key test in the development of products in this category, providing robust scientific evidence of how they perform.
Assessment of stains and residues on fabrics
The anti-stain test assesses the tendency of cosmetic products, particularly deodorants, to leave visible stains on different types of fabric. The product is applied in a controlled manner to standardised fabrics, including white, black and other coloured fabrics, representative of different textile compositions and real-life conditions of use.
After staining, parameters such as the intensity, extent and type of mark (white residues, yellowing or colour transfer) are analysed. The test may also include standardised washing cycles to assess whether stains persist or are removed after washing.
This study is key to developing and validating “anti-stain” claims, optimising the formulation and ensuring the product is compatible with everyday use on any type of garment.
Nail care efficacy
Products designed to care for and strengthen nails require objective evidence to demonstrate their efficacy. At AITEX, we develop specific studies to assess changes in the structural properties of the nail following the application of cosmetic treatments.
Mechanical properties of the nail
Assessment of parameters relating to nail firmness, elasticity and strength. These studies support claims of strengthening and structural improvement.
Nail thickness and physical properties
Analysis of changes in thickness and other physical parameters associated with the condition of the nail. This provides objective evidence of the efficacy of the treatment assessed.
TECHNIQUES AND METHODOLOGIES USED AT AITEX TO SUBSTANTIATE COSMETIC CLAIMS
Instrumental probes for assessing cosmetic efficacy
At AITEX, we combine advanced skin analysis, hair assessment and three-dimensional modelling technologies to obtain objective, reproducible and scientifically sound data. These methodologies make it possible to quantify the benefits of a cosmetic product and provide solid evidence for the validation of cosmetic claims.
Moisturisation and barrier function
Objective assessment of superficial and deep skin hydration, as well as the skin’s ability to maintain barrier function and reduce transepidermal water loss (TEWL). These studies support claims relating to immediate and long-lasting moisturisation, protective effect and care for dry or sensitive skin.
Firmness, elasticity and anti-ageing effect
Analysis of the biomechanical and structural properties of the skin to determine changes in firmness, elasticity, density and visible signs of skin ageing. These methodologies provide quantifiable proof of the efficacy of firming and anti-ageing treatments.
Wrinkles, texture and skin surface quality
Studies designed to assess roughness, smoothness, desquamation, wrinkle depth, texture and other parameters associated with the overall appearance of the skin. The results make it possible to quantify visible improvements and support claims relating to skin renewal and rejuvenation.
Radiance, even skin tone and depigmenting action
Assessment of parameters relating to skin radiance, tone evenness, dark spot reduction, hyperpigmentation control and colour-correcting effects. It also makes it possible to assess the soothing effect associated with reduced skin redness.
Skin comfort and sensitive skin
Assessment of parameters relating to irritation, redness, surface temperature, the physiological balance of the skin and the skin’s response to different stimuli. These methodologies make it possible to demonstrate benefits associated with a soothing effect and care for sensitive skin.
Sebum control and acne-prone skin
Objective quantification of sebum production and analysis of indicators relating to oily or acne-prone skin. These studies support sebum-regulating and mattifying claims, as well as claims relating to an improvement in the overall appearance of the skin.
Hair and scalp efficacy
Studies designed to assess the performance of products for hair, eyelash and scalp care. They make it possible to demonstrate benefits relating to growth, improved density, hair fibre protection, sebum regulation and scalp comfort.
Shine, radiance and healthy appearance
Analysis of the optical properties of skin and hair to quantify variations in surface shine and light reflection. These studies support claims relating to increased radiance, glow effect, matte finish and a healthier appearance.
Nail strength and strengthening
Objective assessment of the mechanical properties of nails to analyse parameters such as strength, elasticity, flexibility and hardness. These studies make it possible to demonstrate the efficacy of strengthening products and support claims relating to stronger, less brittle nails with improved structural quality.
3D analysis and visualisation of results for cosmetic claims validation
Three-dimensional skin assessment provides objective evidence of changes following the application of cosmetic products, using high-resolution images and quantifiable parameters. This technology complements traditional efficacy studies, providing visual evidence that makes results easier to interpret and communicate.
At AITEX, we have AEVA® technology, high-resolution three-dimensional scanning equipment that supports efficacy claims for body and facial cosmetics. Advanced three-dimensional analysis techniques provide a detailed representation of the skin surface and allow the changes produced after the application of cosmetic products to be visualised objectively.
Comparative 3D imaging makes it possible to identify objectively the changes produced in the skin after using a formulation. These representations make results easier to interpret and add significant visual value to cosmetic claims validation.
Sensory evaluation and consumer perception. User panels.
User perception plays a fundamental role in the acceptance and differentiation of cosmetic products. At AITEX, we offer sensory evaluation studies that objectively characterise the user experience through structured methodologies and defined assessment criteria, providing relevant information on the attributes perceived during and after application.
While instrumental studies quantify the efficacy of a product, sensory panels provide information on how users perceive and value those results during their experience of use.
