Advanced wrinkle analysis using PRIMOS CR – project implementation successfully completed!

We are pleased to announce the introduction of a new diagnostic service utilizing the PRIMOS CR system. PRIMOS is a state-of-the-art clinical research tool designed for the evaluation of skin microstructure and advanced wrinkle assessment. It provides precise quantitative results for wrinkle depth, length, volume, number, and surface area within the measured zone.

How does PRIMOS CR work?

PRIMOS CR operates using fringe projection technology, also known as phase-shifting profilometry. In this method, a precisely modulated fringe pattern is projected onto the skin surface. As the light pattern becomes distorted by the skin’s microtopography, the system captures these deformations and reconstructs a highly accurate 3D topography of the skin.

Thanks to the implementation of phase-shifting interferometry, PRIMOS CR achieves exceptionally high axial resolution (up to 0.1 μm) and lateral resolution, making it ideal for analyzing fine skin structures and subtle surface changes.

The development of dedicated analytical scripts and the integration of automated data processing through the VECTRA analysis software.

What parameters does PRMOS CR test?

  • Standardized wrinkle assessment (depth, length, volume),
  • Skin roughness analysis based on parameters: Ra, Rz, Rt,
  • Time-lapse comparison of changes (monitoring treatment effectiveness).

These automated scripts also allow for in-vivo comparative studies (before and after treatment), as well as the evaluation of cosmetic product efficacy. This makes PRIMOS CR an invaluable tool in both clinical practice and R&D laboratories.

Book a consultation with our expert Oliwia Kalinowska and tailor a study protocol according to the latest industry standards. Please contact us at cosm@jsh.com.pl.

September in the cosmetology laboratory – news, tests, and important information for the cosmetics industry

Cosmetics tests is constantly evolving, and with it, the importance of products that have laboratory-confirmed efficacy and safety is growing. September in our cosmetology laboratory is a month full of news and important events – both for cosmetics manufacturers and for anyone who wants to develop their portfolio in accordance with the highest standards. Check out what’s new and how we can support you in the cosmetics testing process.

HOW TO PREPARE DOCUMENTS FOR COSMETIC PRODUCT TESTING?

In order to begin application, stability, or microbiological testing without unnecessary delays, it is important to prepare the documentation properly. Depending on the type of order, different sets of documents are required. Remember, the sooner you provide a complete set of information, the sooner we can begin testing your cosmetic product.

Dermatological Testing Application & Instrumental Testing UV Testing
  • INCI list
  • microbiological test results*

*Not required for products with low microbiological risk.

  • INCI list
  • microbiological test results
  • dermatological test results
  • ID document (including details on the volunteer panel, measurement times, and any client-specific notes)
  • product information sheet including INCI
  • claimed SPF protection

PROFICIENCY TESTING AND “EXCELLENT PERFORMANCE” RESULT

Our Cosmetics Microbiology Laboratory in Tychy took part in proficiency testing for the preservation test (Challenge test), organized by the German company DRRR – an international leader in this field.

We are proud to announce that we have achieved an “Excellent Performance” result, the highest rating confirming our competence.

For our customers, this is a guarantee that the preservation tests we perform are carried out in accordance with the highest quality standards and with complete reliability.

PAO – PERIOD AFTER OPENING. WHAT DOES IT MEAN AND WHY IS IT IMPORTANT?

Cosmetic packaging often features a symbol of an open jar with a label, e.g., 6M, 12M, 24M. This is PAO (Period After Opening), i.e., the shelf life of the product after opening.

Why is PAO testing crucial?

  • It determines how long a cosmetic product is safe to use.
  • It indicates how long a product retains its properties after opening.
  • It helps to avoid the risk of microorganism growth and deterioration of the formulation.

We conduct PAO testing based on physicochemical and microbiological stability tests under conditions that reflect everyday use.

It is worth remembering that cosmetics with a shelf life of more than 30 months do not need to have an expiry date – the PAO symbol is sufficient.

Would you like to check the shelf life of your product? Contact our expert by filling out the contact form or sending a message to: cosm@jsh.com.pl

CONFIRMATION OF MARKETING CLAIMS – IN VIVO TESTS

Claims such as “moisturizes the skin,” “reduces wrinkles,” or “restores radiance” require confirmation by reliable test results. In our laboratory, we conduct in vivo tests that provide a solid basis for marketing communication.

Why choose our laboratory?

  • We conduct tests on appropriately selected groups of volunteers.
  • We ensure the safety and comfort of participants.
  • We use modern assessment methods in accordance with current standards.

Thanks to the results obtained, your marketing messages will be credible and competitive on the market.

Ask about our range of application and usability tests that support the positioning of cosmetic products.

Increase knowledge about the safety of your supplements

Product awareness is growing among consumers. Recipients are increasingly verifying compositions, seeking information on studies conducted, and choosing products most suited to their needs.

Trends in healthy eating and supporting the body with dietary supplements have forced manufacturers and distributors to pay more attention to the quality of pharmaceuticals and confirm it with independent research. Although dietary supplements are not drugs and are not subject to the same stringent regulations, growing consumer awareness is challenging them to subject their products to the best possible scrutiny.

The choice of remedies and their availability is virtually unlimited. Widespread advertising, however, is not an adequate incentive for informed consumers. Information about product efficacy and safety also plays an important role. Recipients increasingly pay attention to whether a product has been tested by accredited testing laboratories. Keeping in mind the growing knowledge of consumers, more and more supplements are checked by testing methods based on polish and international standards (PN & ISO).

At the J.S. Hamilton laboratory, we test, among other things:

  • microbiological safety,
  • pyrrolizidine and tropane alkaloids,
  • pesticide residues,
  • heavy metal content,
  • vitamin and mineral content,
  • stability of the dietary supplement,
  • various types of physicochemical parameters,
  • as well as many other parameters.

It is worth noting that dietary supplements of adequate quality can be a valuable addition to a balanced diet, but as long as they are not properly controlled, one cannot be sure of the quality of the available products. By raising awareness about the safety of a product, through research confirming its composition, it is easiest to build trust in products.

At J.S. Hamilton, we provide the highest quality of customer care and closely tailored offerings.

If you have any questions or concerns, J.S. Hamilton Experts are at your service.
