Clinical Assessments for More In-Depth Analysis


When it comes to testing your personal care products, we offer add-ons to supplement your microbiome research efforts and facilitate your testing experience.

It has become clear in recent years that differentiation is key when creating a formulation for the competitive market, however, differentiation can be incredibly straightforward when backed with the data and scientific evidence to support it.

Not only will you differentiate your brand, you will also demonstrate your commitment to providing leading-edge and effective solutions for your customers’ personal care and skincare needs.


The only way to understand how a product performs is by putting it to the test


Hydration Measurement (Corneometry and TEWL)

Gain a comprehensive understanding of your product's impact on moisture retention, skin hydration and overall skin barrier function. This data can guide the development of effective moisturizing formulations.

perception questionnaire.

Perception Questionnaire

Uncovering how users experience and interact with products. These surveys offer valuable insights into subjective factors like texture, scent, and overall satisfaction ensuring that your scientific data is enriched. 


Elasticity Measurement (Elastometer)

Unravel the effect your product has on the skin’s elasticity through the use of elastometers, allowing you to position your product within a firming category with demonstrated benefits for graceful aging.

high resolution imaging.

High-Resolution Imaging

Use before and after images to provide visual evidence of a product’s impact on the skin’s appearance. These tangible comparisons offer brands the ability to objectively assess changes in the skin. 

dermatologist assessment.


Measure and quantify inflammatory disease, atopic dermatitis (through SCORAD), psoriasis (through PASI), comedogenicity, and other hallmarks of skin conditions, by our board-certified and in-house dermatologists.

skin ph measurement .

Skin pH Measurement

Maintain the delicate balance of the skin's acid mantle with your product by measuring pH to ensure compatibility and minimise the risk of irritation for a gentle, biome supporting formulation. 



  • What is Sequential's testing platform?
    Sequential has developed the gold standard test for microbiome-friendly products, in vivo (in, or on, humans). Finally, we can give some certainty about if a product is truly affecting the microbiome. We offer a complete end-to-end solution to support microbiome-friendly claims. From consultancy and study design to our proprietary microbiome testing kits. We analyse, interpret and report our findings to meet your needs.
  • Why is it necessary to test the microbiome in vivo?
    At present, there are no regulations for microbiome-related formulas that brands and formulators can follow, however, it has been universally acknowledged that the in vivo method of conducting clinical studies is becoming critical and paramount to getting marketing claims through. When regulations are introduced, which may be imminent, the in vitro system will find itself lacking, resulting in limited claims and certifications that do not hold their value. This is why, we at Sequential strive to offer an in vivo approach, knowing full well that we want our client's claims to be significantly backed by scientific and quantifiable data.
  • What type of sequencing technology does Sequential use for analysis?
    We offer four types of sequencing techniques including qPCR with our Smart Probes™, 16S, ITS and Shotgun Metagenomics. Using next-generation sequencing of the collection of microorganisms found on the body, during product usage, Sequential investigates the microbial diversity, and particular microorganisms we know are important and play a role in a healthy microbiome.
  • Does Sequential offer claims certification for tested products?
    We provide our clients with a certification to claim “Maintains the Microbiome” subject to in vivo testing results which can be used in communication efforts. Once your product is tested with our qPCR Smart Probes™ and has shown favourable results in supporting the microbiome, we can certify your product with our Maintains the Microbiome certification seal. We have ensured that our seal and certification are backed by quantifiable data and scientifically significant markers. The aim is to ensure our clients feel confident in making their claims and can communicate the true benefit of their microbiome formulations.
