What Disrupts the Skin Microbiome? What Disrupts the Skin Microbiome? The skin microbiome is an intricate ecosystem of bacteria, fungi, and viruses that protect and maintain skin health (Smythe & Wilkinson, 2023). It acts as a defence against harmful pathogens, regulates inflammation, and supports the skin’s overall barrier function. However, disruptions to this microbiome can eventually lead to skin issues like acne, eczema, and various skin infections (Wallen-Russell, 2019). Understanding these disruptions is key to making informed choices about skincare, diet, and lifestyle to promote healthy skin. 1. Harsh Skincare Products Personal care products like soaps and lotions can disrupt the skin microbiome by removing natural oils and beneficial microbes. Many contain harsh chemicals, such as preservatives and fragrances, which reduce microbial diversity and promote the growth of harmful bacteria like Staphylococcus aureus. A study by Wallen-Russel (2018) found that synthetic ingredients generally lower the positive effects on skin biodiversity. Using essential, pH-balanced skincare products is recommended to maintain a healthy skin microbiome. 2. Antibiotics and Medications The use of antibiotics is a major disruptor of the skin microbiome. While antibiotics are essential for treating bacterial infections, their overuse or misuse can eliminate beneficial bacteria alongside harmful pathogens. This disruption can lead to a decrease in microbial diversity and the dominance of antibiotic-resistant bacteria, which may contribute to skin conditions like eczema and psoriasis. Studies have shown that prolonged antibiotic use can have lasting effects on the skin's microbial communities, making it more prone to dysbiosis and related diseases (Byrd et al., 2018). 3. Environmental Factors Environmental exposures are a major cause of skin microbiome disruption. Pollution, particularly airborne particulate matter and toxins, weakens the skin barrier and alters microbial diversity by causing oxidative stress and inflammation. This imbalance favours harmful microbes while reducing beneficial ones. Araviiskaia et al. (2019) found that chronic inflammatory skin conditions like eczema and psoriasis tend to worsen in individuals, including children, when exposed to high pollution levels. While moderate sun exposure is beneficial, excessive UV exposure can cause acute and chronic skin damage, including inflammation, premature ageing, and increased cancer risk. Patra, Sérézal & Wolf (2020) highlights how UV radiation disrupts the skin microbiome, potentially leading to dysbiosis and compromised skin health. 4. Diet and Lifestyle Diet and lifestyle choices can also direct the overall health of the skin microbiome. Ghosh, McMahon & Lappin (2021) revealed that a plant-based diet can positively influence the skin microbiome, reducing inflammation and oxidative stress, thereby supporting overall skin health. Conversely, diets high in processed foods and saturated fats can negatively impact the microbiome and lead to health issues, including skin conditions. 5. Stress and Hormonal Changes Stress can significantly impact the skin microbiome, primarily through hormonal and behavioural changes. Stress activates the hypothalamic-pituitary-adrenal (HPA) axis, leading to increased production of cortisol and other stress hormones. This hormonal response can cause inflammation and immune dysregulation, which may exacerbate various skin conditions like psoriasis, eczema, and acne. Additionally, stress can lead to changes in behaviour, such as neglecting skincare routines or engaging in unhealthy habits (e.g., smoking, poor diet) that further disrupt the skin microbiome (Holmes et al., 2015).

TARGETED SKIN PANEL Rosacea Targeted Panel 23 Smart Probes ™ Rosacea Panel Validated targets: Demodex mites, Bacillus oleronius, Corynebacterium kroppenstedtii Absolute Quantification End-to-end Service Qet a Quote Unlock the Secrets of Rosacea with Sequential's Cutting-Edge Microbiome Testing Why Microbiome Testing for Rosacea? Rosacea is a chronic skin condition affecting an estimated 16 million Americans and millions more worldwide, primarily adults over 30 (National Rosacea Society). Characterized by redness, visible blood vessels, and inflammation, rosacea can significantly impact an individual’s quality of life. Research suggests that the skin microbiome plays a crucial role in the development and severity of rosacea. Specifically, imbalances in microbial populations, such as an overgrowth of Demodex mites or harmful bacteria, can exacerbate symptoms. In vivo testing of skincare products for rosacea is essential to ensure that formulations are compatible with the unique microbiome of rosacea-prone skin. Such testing allows researchers to observe real-world effects on microbial balance and inflammation, ensuring that products do not unintentionally worsen symptoms. Without this careful testing, products may disrupt the microbiome further, leading to increased redness, irritation, or flare-ups. Sequential is leading the way in microbiome testing for the industry. With a specialized focus on skin conditions, we have developed an innovative solution tailored to help you understand the root causes of rosacea at the microbial level. Our proprietary sequencing panel is designed specifically to offer in-depth analysis of rosacea-associated microbiota, giving you the tools to transform skincare solutions. Customized Analysis Tailored insights specific to rosacea-prone skin, allowing your R&D team to develop more personalized and effective products. Actionable Data Leverage detailed reports to guide formulation decisions and validate product efficacy with precision. Product Innovation New rosacea treatments or enhancing existing lines, our data helps you create targeted solutions with proven results. Precision Sequencing Target specific microbial communities associated with rosacea development and severity. Smart Probe s ™ Our dedicated team of scientists has developed a revolutionary method for evaluating microbes through our Smart Probes™, a proprietary panel that includes 23 key microbes specifically identified as having the most significant impact on skin health. To further understand the complex relationship between rosacea and the skin microbiome, we utilize qPCR technology. This advanced method allows us to accurately quantify microbial populations on the skin, offering deeper insights into how rosacea affects the balance of beneficial and harmful microbes. By closely monitoring how skincare products interact with these microbes, companies can develop solutions that not only target rosacea symptoms but also help restore a healthier, balanced skin microbiome, providing long-term relief for sufferers.

Yet beyond the visible changes to tone and texture, light also interacts with the skin microbiome. Understanding how different wavelengths influence this ecosystem is key to ensuring that light enhances, rather than harms, our skin’ How Pregnancy and Postpartum Transform the Skin Microbiome During pregnancy, the skin microbiome undergoes significant shifts. Across the trimesters, both the composition and behaviour of skin bacteria change. Postpartum, the maternal skin microbiome continues to evolve which is influenced by hormonal resets, environmental exposures, and hygiene practices. These shifts can also influence an infant’s earliest microbial encounters, during a critical period of skin development. What We Know: Pregnancy significantly changes the skin mic Understanding the Microbial Roots of Seborrheic Dermatitis Seborrheic dermatitis (SD) is a common inflammatory skin condition primarily affecting the scalp, face and chest. It appears as red, flaky, greasy patches or plaques and can cause itching and discomfort. It is a non-contagious condition varying in severity, from mild dandruff to persistent inflamed lesions. What we know: SD is linked to three main factors: increased sebum (oil) production, colonization by Malassezia yeast, and an abnormal immune response.

While traditional wound dressings effectively promote healing, there’s growing interest in innovative approaches that address post-burn scarring more effectively. What We Know: Traditional dressings help close and heal wounds by providing hydration and antimicrobial protection, but they aren’t designed to prevent or treat post-burn scarring. Burns disrupt the skin’s microbial balance, favouring heat-loving microbes like Aeribacillus, Caldalkalibacillus and Nesterenkonia while reducing beneficial bacteria such as Cutibacterium, Staphylococci and Corynebacteria . Increased levels of Corynebacterium are linked to higher infection risks, whereas Staphylococci and Cutibacterium are associated with lower infection rates post-burn (Yang et al., 2024). Despite reduced bacterial richness at the genus level, burn patients exhibit increased microbial community diversity and evenness. This altered microbial landscape, marked by a lower overall bacterial burden and an overgrowth of Staphylococcus species, highlights a persistent dysbiotic state in the skin microbiota during the subacute phase of wound healing (Liu et al., 2018) . Industry Impact and Potential: @Healome Therapeutics has developed a groundbreaking bioactive skin dressing technology, recently cleared by the @Medicines and Healthcare products Regulatory Agency (MHRA) for a phase I trial aimed at reducing scarring. The trial, conducted at Queen Elizabeth Hospital in Birmingham, UK, involves 25 patients with burns covering 3-20% of their body surface. Healome’s innovative dressing is a clear film that not only offers the benefits of traditional wound dressings but also incorporates synthetic human-derived decorin protein, which plays a critical role in wound healing. This protein reduces the inflammatory response and regulates the wound’s microenvironment. Early research suggests that this approach may reduce fibrosis and promote tissue regeneration, offering new hope for scar management in burn patients. Products like Healome’s dressing showcase the exciting potential of using the microbiome and skin environment to enhance wound healing, paving the way for future innovations in burn care. Our Solution: At Sequential, we offer comprehensive services for evaluating product impacts and formulations, supported by a vast database of over 20,000 microbiome samples and 4,000 ingredients, along with a global network of more than 10,000 testing participants. Our customizable microbiome studies simulate real-world testing scenarios, ensuring that your products preserve biome integrity while delivering optimal results.

Is Swimming Wrecking Your Skin Microbiome? Swimming is a widely enjoyed physical activity that provides various health benefits, such as improved cardiovascular fitness, enhanced muscle strength, and reduced stress levels. Nevertheless, swimming also involves exposure to different water environments, including chlorinated pools, seawater, and freshwater lakes. Each of these environments possesses distinct chemical and microbial properties that can uniquely affect the skin microbiome. Consequently, comprehending the significance of the skin microbiome in swimming is essential. What we know: Studies have found that exposure to chlorinated pool water reduces microbial diversity on the skin, as it acts as a disinfectant, killing both harmful and beneficial bacteria, which can lead to an imbalance in the skin microbiome. This imbalance may increase the risk of skin conditions like dermatitis and infections (Puce et al ., 2022). Ocean water contains a diverse range of marine bacteria, thereby enhancing the diversity of the skin microbiome. The ocean water simultaneously removes resident skin bacteria while depositing ocean-borne bacteria onto the skin (Nielsen et al ., 2019). The predominating phyla Actinobacteria , Firmicutes , and Proteobacteria on the skin changed after swimming when compared to before swimming tends to decrease, whereas Bacteroidetes tends to increase. As time passed, the bacterial community composition trended towards baseline (Nielsen et al ., 2019). The quantity of Vibrio spp. found on human skin was over ten times higher than that in the ocean water sample (which was only 0.032%), indicating that Vibrio spp. has a particular affinity for adhering to human skin (Nielsen et al ., 2019). Industry impact & potential: Research shows that males are more prone to acquiring infections from Vibrio vulnificus and Aeromonas spp. following water exposure. Future research could provide valuable insights into the factors contributing to these infections and explore potential differences in the skin microbiome between males and females after such exposure (Nielsen et al ., 2019). Formulations such as post and pre-swim cleansers and moisturizers should be designed to aid in microbiome recovery while also protecting the skin from chlorine and salt damage. Our solution: Sequential, is a company focusing on microbiome studies. We carry out various services from clinical testing to helping with formulations. We have at home testing kits that will allow you to discover the state of your skin microbiome. Through our Skin Health Tracker app, we can give you tips on how you can improve your skin and the microbiome. Reference: Nielsen MC, Jiang SC.

Exploring the Impact of The Scalp Microbiome on Alopecia Treatments: New Insights and Innovations The scalp microbiome plays a crucial yet often overlooked role in the development and treatment of alopecia. Studies have shed light on how rebalancing these microbes can significantly enhance the efficacy of treatments for hair loss, offering new hope for patients. What We Know: Cutibacterium spp. and Staphylococcus spp . constitute about 90% of healthy scalp microbiomes, with Corynebacterium spp., Streptococcus spp., Acinetobacter spp . and Prevotella spp . making up the remaining 10% (Jo et al., 2022) . Alopecia patients’ scalp microbiomes exhibit increased C. acnes , Stenotrophomonas geniculata, Wallemia and Eurotium , as well as reduced Malassezia, when compared to healthy individuals. Therefore, it is likely that an imbalance in scalp microbiota may contribute to alopecia (Zhang et al., 2024) . Industry Impact and Potential: Platelet-rich plasma (PRP) has proven effective in treating alopecia, but its impact on the scalp microbiome was previously unexplored. A recent study revealed that PRP treatment rebalances the scalp microbiome, specifically increasing Cutibacterium levels while decreasing Staphylococcus and Lawsonella levels (Zhang et al., 2024) . Cutibacterium plays a vital role in maintaining skin homeostasis and is crucial for lipid regulation, follicular niche competition, immune regulation and mitigating oxidative stress. Furthermore, the balance between Cutibacterium and Staphylococcus is important for regulating immune response. Reduction in Lawsonella suggests decreased scalp sebum production following treatment. This is relevant to alopecia treatment, as imbalances in sebum production can exacerbate hair loss by contributing to inflammation and follicle damage (Zhang et al., 2024) . Lactic acid bacteria (LAB), Limosilactobacillus fermentum LM1020 and its heat-treated version HT-LM1020, can help promote hair growth on human scalp tissue and dermal papilla cells. These bacteria work with other ingredients to fight hair loss by boosting cell growth and regulating the expression of proteins important for cell division (Bae et al., 2024) . AMOREPACIFIC patented a composition that uses extracellular follicles derived from LAB to prevent hair loss, stimulate hair growth and support overall hair health. These extracellular follicles (cellular components or secretions released by the bacteria) represent a promising advancement in alopecia treatment, offering potential benefits for both hair and scalp health. Our Solution: With a database of over 20,000 microbiome samples and 4,000 ingredients, and a global network of more than 10,000 testing participants, Sequential offers comprehensive services to evaluate product impacts and formulations. Our customisable microbiome studies provide real-life context testing, and our formulation support ensures products maintain biome integrity, making us the ideal partner for your product development and efficacy needs.

What we know: Studies have found that exposure to chlorinated pool water reduces microbial diversity on the skin, as it acts as a disinfectant, killing both harmful and beneficial bacteria, which can lead to an imbalance in the skin microbiome. This imbalance may increase the risk of skin conditions like dermatitis and infections (Puce et al ., 2022). Ocean water contains a diverse range of marine bacteria, thereby enhancing the diversity of the skin microbiome. The ocean water simultaneously removes resident skin bacteria while depositing ocean-borne bacteria onto the skin (Nielsen et al ., 2019). The predominating phyla Actinobacteria , Firmicutes , and Proteobacteria on the skin changed after swimming when compared to before swimming tends to decrease, whereas Bacteroidetes tends to increase. As time passed, the bacterial community composition trended towards baseline (Nielsen et al ., 2019). The quantity of Vibrio spp. found on human skin was over ten times higher than that in the ocean water sample (which was only 0.032%), indicating that Vibrio spp. has a particular affinity for adhering to human skin (Nielsen et al ., 2019). Industry impact & potential: Research shows that males are more prone to acquiring infections from Vibrio vulnificus and Aeromonas spp. following water exposure. Future research could provide valuable insights into the factors contributing to these infections and explore potential differences in the skin microbiome between males and females after such exposure (Nielsen et al ., 2019). Formulations such as post and pre-swim cleansers and moisturizers should be designed to aid in microbiome recovery while also protecting the skin from chlorine and salt damage. Our solution: Sequential, is a company focusing on microbiome studies. We carry out various services from clinical testing to helping with formulations. We have at home testing kits that will allow you to discover the state of your skin microbiome. Through our Skin Health Tracker app, we can give you tips on how you can improve your skin and the microbiome. Reference: Nielsen MC, Jiang SC.

Exploring the Impact of The Scalp Microbiome on Alopecia Treatments: New Insights and Innovations The scalp microbiome plays a crucial yet often overlooked role in the development and treatment of alopecia. Studies have shed light on how rebalancing these microbes can significantly enhance the efficacy of treatments for hair loss, offering new hope for patients. What We Know: Cutibacterium spp. and Staphylococcus spp . constitute about 90% of healthy scalp microbiomes, with Corynebacterium spp., Streptococcus spp., Acinetobacter spp . and Prevotella spp . making up the remaining 10% (Jo et al., 2022) . Alopecia patients’ scalp microbiomes exhibit increased C. acnes , Stenotrophomonas geniculata, Wallemia and Eurotium , as well as reduced Malassezia, when compared to healthy individuals. Therefore, it is likely that an imbalance in scalp microbiota may contribute to alopecia (Zhang et al., 2024) . Industry Impact and Potential: Platelet-rich plasma (PRP) has proven effective in treating alopecia, but its impact on the scalp microbiome was previously unexplored. A recent study revealed that PRP treatment rebalances the scalp microbiome, specifically increasing Cutibacterium levels while decreasing Staphylococcus and Lawsonella levels (Zhang et al., 2024) . Cutibacterium plays a vital role in maintaining skin homeostasis and is crucial for lipid regulation, follicular niche competition, immune regulation and mitigating oxidative stress. Furthermore, the balance between Cutibacterium and Staphylococcus is important for regulating immune response. Reduction in Lawsonella suggests decreased scalp sebum production following treatment. This is relevant to alopecia treatment, as imbalances in sebum production can exacerbate hair loss by contributing to inflammation and follicle damage (Zhang et al., 2024) . Lactic acid bacteria (LAB), Limosilactobacillus fermentum LM1020 and its heat-treated version HT-LM1020, can help promote hair growth on human scalp tissue and dermal papilla cells. These bacteria work with other ingredients to fight hair loss by boosting cell growth and regulating the expression of proteins important for cell division (Bae et al., 2024) . AMOREPACIFIC patented a composition that uses extracellular follicles derived from LAB to prevent hair loss, stimulate hair growth and support overall hair health. These extracellular follicles (cellular components or secretions released by the bacteria) represent a promising advancement in alopecia treatment, offering potential benefits for both hair and scalp health.

Scalp Microbiome Testing | Sequential Scalp Microbiome Testing As the scalp care industry grows, consumers demand transparency from the brands formulating their products. It has become essential for formulators to create products they are willing to test to present scientifically backed data-driven evidence of their products' true effects. Sequential offers microbiome testing for your scalp care formulations, ranging from scalp serums, shampoos, conditioners, oils, etc. We are dedicated to understanding how your product interacts with the scalp and its microbes. Depending on how in-depth you want to go, we offer qPCR, 16S, ITS, and Shotgun Metagenomics. Download Case Study! Personalized Approach to Testing Unlike other methodologies present within the industry, Sequential's approach ensures that your product's data and analysis will stand the test of industry regulations when they are introduced. You can tailor your study entirely to your unique requirements. Test Products in a Real-Life Context The microbiome comprises a complex ecosystem of microorganisms that live together in a delicate balance, which is why it's best to test directly upon it directly. To fully understand the impact a product is having on the microbiome, in vivo is the only way. Collect Longitudinal Data With in vivo testing we can design your study around the extended use of a product over multiple time points. This allows us to review how a product is performing before and after usage, but also take into account its gradual impact on the microbiome. Measure Against a Control Group Measure a product against a control group that might have a different percentage of your active ingredient within its formulation or no active at all. This will allow for deeper insights into the impact of a formulation on microbial balance and diversity. 4 Sequencing Reports To Pick From Depending on your development stage and what you are interested in studying we offer qPCR, 16S, ITS, and Shotgun Metagenomics. With our qPCR Smart Probes™ we can go down to the strain level in our analysis. Personalize Your Microbiome Study! Unlike hair, the scalp is formed of a living community of microorganisms such as bacterial and fungal players that can influence the balance of the scalp microbiome, even the subtlest of imbalances can lead to issues such as dandruff, itching, and irritation, resulting in unwanted flaking. Smart Probe s ™ Our dedicated team of scientists have developed a method of evaluating microbes through our Smart Probes ™ . These refer to a panel of 20 key microbes we have specifically identified as having the most impact on scalp health. Over and above the taxonomic characterisation that 16S offers, which gives us a snapshot of all the genus present within a collected sample (Cutibacterium , Staphylococcus , etc.) our targeted approach takes it a step further, opening the lens to the species (C. acnes ), sub-species (C. acnes defendens ) and even strains within them. This is a crucial distinction as not all strains of a species behave similarly. We find that within these species there are strains associated with inflammation and strains that are commensal, and beneficial. Gold Standard Certification Sequential has developed the gold standard test for products designed to target the microbiome, in vivo (in, or on, humans).
