QACS offers skin Cosmetic Microbiome studies in the form of clinical trials to substantiate product microbiome claims. Our dedicated team offers a variety of options on skin microbiome evaluation to address your product needs. Microbiome studies, adopted to your product’s needs and budget, are provided in the form of customized protocols. At QACS we conduct Microbiome Balance and Microbiome Friendly studies.

Quorum Quenching has been proposed as a potential strategy to modulate skin microbes behavior and to promote skin health. We have developed a protocol for screening cosmetic formulations, for their ability to inhibit quorum sensing of targeted microbes such as P.acnes and S.aureus. With Quorum Quenching Analysis from QACS Lab you can assist the creation of anti-acne products by disrupting the biofilms formed by pathogenic skin microbes, making them more susceptible to immune clearance and antimicrobial agents!

At QACS we conduct Sensory evaluation of cosmetics, household and personal care products following international standardized protocols and practices.

Focused on vision, smell and touch, sensory testing of cosmetic products can investigate sensorial properties in relation to their consumer liking and sensory profile (color, smell, rheological properties).

In QACS Lab:

• we offer documented results of sensory analysis, based on integrity and impartiality.
• our testing booths are designed according to ISO 8589:2007 and we use special sensory software for data collection and statistical analysis.
• we pay close attention to selection and implementation of the appropriate sensory methods and inclusion criteria of panelists to the studies.

A particularly useful tool for the sensory evaluation of cosmetics is the descriptive analysis method or known as Profiling. It includes the detection and quantification of the sensory attributes by expert sensory panelists. The attributes are scored with objective criteria and the results are presented in diagrams, such as spider plots.

Sensory experts, trained judges and consumers participate in the assessment of the sensorial characteristics of products. The sensory perception in terms of smell, aspect, and texture is studied and described for the optimization of new developments and evaluated in comparison to Market Leaders. Sensory testing is a powerful tool in product benchmarking.

 

At QACS, we conduct use tests to evaluate the clinical efficacy of cosmetic products. Volunteers use the product under normal conditions for a specified period, following criteria chosen by the study sponsor to match the target consumer profile. Our studies are supervised by trained clinical professionals, such as dermatologists, ophthalmologists, dentists, or cosmetologists, depending on the product’s target area.

We provide suggested questionnaires for volunteers to complete during and/or at the end of the study, ensuring comprehensive feedback. Trust QACS Lab for scientifically validated use tests that enhance the credibility and effectiveness of your cosmetic products.

Our Antioxidant Testing service evaluates the protective efficacy of cosmetic products, focusing on their ability to counteract oxidative stress from environmental factors like UV radiation and oxygen. This testing supports direct claims such as:

• Helps to prevent the formation of free radicals caused by UV exposure.
