SKINCARE FORMULATIONS Regular to Atopic Skin, Start Formulating Today! What Contributes to a Microbiome Supporting Formulation? When creating a product that "maintains the microbiome", it is crucial to understand that every ingredient used is important. Hero ingredient-led philosophy cannot be applied in the formulation process as it is the blend of each ingredient that will create a product to support and improve the balance of the skin microbiome. Fermented ingredients (postbiotics) and those that act as food for microbes (prebiotics) are also known to have a positive impact on formulations when paired with the right preservative systems, surfactants, emollients, etc. It is still rare to find live bacteria (probiotics) in formulations, however, if encapsulated correctly, it could show improvement in the microbiome balance. Prebiotics Prebiotics beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria on the skin, and thus improves host health. Prebiotics act as food for the microbes on the skin, and allow good bacteria to grow and thrive. Probiotics Probiotics are living microorganisms that confer benefit to the host when applied to the body. Because probiotics are live bacteria, it is incredibly difficult to preserve and put into skincare products (especially when skincare contains preservatives). In fact, some products on the market that say they use probiotics, are actually using prebiotics or postbiotics. Postbiotics Postbiotics are the byproduct of fermented live bacteria (probiotics) or inactivated microorganisms. The process of fermentation releases nutrients inside of the bacteria and holds concentrated and nourishing skin health benefits that help to balance the skin microbiome.

Request a Consultation Ashfi Rahman, Co-founder at HonestStory "Sequential gave us completely essential consulting work on microbiome skincare formulations. They are the only company out there that combines their knowledge of microbiome testing with formulation expertise, and we're very happy to be working with them to develop the first microbiome skincare in India." FAQ 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.

Why is a Human Approach Better when it Comes to Personal Care Product Testing? 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 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. in vitro Lab Testing in vivo Human Testing Analyze select bacteria within a lab setting Narrow view of microbiome: Isolated from other bacteria Cannot extract meaningful conclusions on how the product will interact with its place of application Limited analysis: brief snapshot of how the product interacts with an isolated bacteria Analyze all bacteria within its natural context Broad view of microbiome: you can see interactions between bacteria Can extract meaningful conclusions on how the product will interact with its place of application Longitudinal analysis: evaluate the product over time and its impact on the microbiome Normal to Atopic Skin It’s crucial to test your product on individuals suffering through the concerns your active ingredients are targeting. This is why we believe in a fully personalized approach to candidate recruitment and human testing, bringing forward those individuals that your products are genuinely designed to help.

How do you Formulate Skincare Products? How do you Formulate Skincare Products? Formulating skincare products is a process that combines different ingredients to provide targeted skin benefits. The type of product being used, the particular skin concern and the formulation's stability and effectiveness are some of the variables that can affect the formulation process. Key Components of Skincare Formulation: Choosing the right ingredients when formulating skincare products is important, as it determines the product's effectiveness. Moreover, the chemical composition of the ingredients and their concentrations in a formulation is as important as establishing its overall effect on our health. Most skincare products typically include 15 to 20 ingredients in their formulation (Goyal & Jerold, 2023). Water Ultra-pure distilled water serves as the foundation for nearly every cosmetic formulation, including creams, lotions, makeup, deodorants, shampoos, and conditioners. It functions primarily as a solvent, helping to emulsify ingredients and ensure a smooth and consistent texture in the final product (Goyal & Jerold, 2023). Emulsifiers Promotes the formation of a homogenous and consistent texture in the formulation by encouraging the suspension of water and oil (Goyal & Jerold, 2023). Humectants Humectants are crucial for the skin's hydration balance, moisture retention, and desiccation prevention. Multiple hydroxyl, carboxyl, or other polar groups found in humectants have the ability to create hydrogen bonds with water molecules, which allows them to absorb and hold onto moisture (Du et al., 2024). Thickeners Long carbon chains and polar groups like hydroxyl, carboxyl, and amide groups make up most of the thickeners. Within solutions, these long-chain structures increase the viscosity of the solution by increasing its resistance to flow (Du et al., 2024). Preservatives Preservatives are added to prevent the growth of pathogenic and non-pathogenic microorganisms that could degrade the product or negatively impact the consumer's health De et al., 2017). Active Ingredients Ingredients that offer therapeutic advantages and improve the efficacy of skincare products, such as hyaluronic acid, are used as active components in formulations (Morganti et al., 2023). Therefore, selecting the appropriate active ingredient is crucial to creating a high-quality skin care product (Calixto & Maia, 2017). Stability testing and sensory analysis The formulations afterwards need to be tested for their stability at different temperatures and for sensory evaluation such as spreadability, cohesiveness, consistency, firmness and viscosity (Calixto & Maia, 2017). Targeting the microbiome with Skincare products Our skin is home to millions of microbial species called the Skin microbiome. A balance of all these microbes is crucial to obtain healthy skin. Imbalances cause several skin problems such as acne, rosacea…etc. So when formulating skincare products it is important to investigate each ingredient's impact on the skin microbiome. Conclusion It is of great importance to carefully consider the ingredients that are put into skincare formulations whilst considering the skin microbiome. Developing safe and efficient products is frequently the main goal, there is also a growing tendency towards customisation based on the demands of each individual's skin. This trend towards customised skincare highlights the value of customised solutions in the beauty industry and represents a deeper awareness of the various needs of various skin types and conditions.
