ABSTRACT
The skin microbiome remains one of the most promising directions in modern
dermatocosmetology, both in research and practical application. This article explores the
structure and function of the skin microbiome and its role in skin health and cosmetic product
development. The impact of probiotic, prebiotic, and postbiotic cosmetics on the microbiome, as
well as modern microbiome-based products and their effectiveness, are discussed based on
scientific evidence. The article also highlights ways to maintain microbiome balance, its use in
cosmetic procedures, and future perspectives.

INTRODUCTION
The skin microbiome is the collection of microorganisms living on the surface of the skin,
including bacteria, fungi, viruses, and other microscopic organisms. This community plays a
vital role in skin health, defense mechanisms, and aesthetics. Recent research has demonstrated
that the skin microbiome is a complex, multifaceted system.
In dermatocosmetology, the microbiome has emerged as a new paradigm. Unlike traditional
cosmetics, which focus on chemical solutions, microbiome-based products emphasize natural,
effective approaches. This has sparked a revolution in the cosmetic industry.
The importance of microbiome studies lies in the fact that the skin houses about 10% of the total
div microbiota, reaching up to 10^12 microorganisms. These figures highlight the complexity
and significance of the microbiome.
THE SKIN MICROBIOME SYSTEM
The skin microbiome consists of bacteria, fungi, viruses, and archaea. Dominant bacterial genera
include Staphylococcus, Streptococcus, Corynebacterium, Propionibacterium, and Micrococcus.
Distribution varies by div site: oily areas (face, back, chest) are rich in Propionibacterium acnes;
dry areas (hands, feet) host more Staphylococcus epidermidis; moist areas (armpits, between toes)
have more Corynebacterium.

Key functions:
- Protection: prevents harmful microbes from colonizing the skin
- Immune regulation: influences inflammation and immune responses
- Barrier support: helps maintain moisture and integrity
Microbiome balance is influenced by age, gender, location, diet, hygiene, stress, and other
factors. A healthy microbiome is diverse and well-balanced.
MICROBIOME AND SKIN DISEASES
Microbiome imbalance (dysbiosis) is linked to many skin disorders, including atopic dermatitis,
rosacea, acne vulgaris, and seborrheic dermatitis.
- Acne: overgrowth of Propionibacterium acnes triggers inflammation
- Atopic dermatitis: increase in Staphylococcus aureus, reduction in beneficial microbes, leads to
barrier disruption
- Rosacea: involvement of Demodex folliculorum and Bacillus oleronius, intensifying redness
and swelling
PROBIOTIC COSMETICS
Probiotic cosmetics contain live beneficial bacteria or their metabolites. Moisturizers with
probiotic lysates are now commercially available and scientifically validated.
Mechanisms:
- Competition with harmful microbes
- Production of antimicrobial substances like bacteriocins
Common strains: Lactobacillus, Bifidobacterium, Streptococcus thermophilus, Vitreoscilla
filiformis
- Lactobacillus: produces lactic acid, balances skin pH
- Bifidobacterium: synthesizes vitamins and amino acids, reduces irritation
- Vitreoscilla filiformis: anti-inflammatory properties
PREBIOTIC COSMETICS
Prebiotic cosmetics support the growth and activity of beneficial bacteria. These substances are
not microbes but feed them.
Common ingredients: oligosaccharides, inulin, fructooligosaccharides, alpha-glucan
Studies show improved skin hydration and microbiome diversity after 4 weeks of use. Prebiotics
play a key role in restoring balance, especially in dysbiosis.

POSTBIOTIC COSMETICS
Postbiotics are bioactive compounds produced by probiotic bacteria. They offer the benefits of
probiotics without containing live microbes, ensuring safety and stability.
Key compounds: peptidoglycans, teichoic acids, short-chain fatty acids, bacterial
exopolysaccharides
Effects:
- Strengthen skin barrier
- Reduce inflammation
- Accelerate regeneration
MODERN MICROBIOME RESEARCH
Modern literature focuses on microbiome composition, function, significance, and its role in
aging. These studies guide the development of innovative products.
Japanese studies show links between microbiome evolution and signs of aging, paving the way
for anti-aging products.
Advanced technologies like genomic sequencing, metabolomics, bioinformatics, and AI help
analyze microbiome systems at a deep level.
CLINICAL STUDIES AND EFFICACY
Clinical trials up to 2024 examined how dermatological treatments affect the microbiome.
Findings:
- Improve skin barrier function by 25–30%
- Reduce inflammation by 40–50%
- Increase hydration and elasticity by 20–35%
Probiotic cosmetic effects appear within 2–4 weeks, with microbiome balance improving first,
followed by visible skin improvements.
Results vary by age: younger users see faster effects; older users see slower but more stable
improvements.
APPLICATION IN COSMETIC PRACTICE
Microbiome cosmetics are available as creams, serums, toners, masks, and cleansers, each with
distinct advantages:
- Creams: deep and long-lasting effects
- Serums: fast absorption and concentrated action
- Toners: daily use to maintain balance
Usage guidelines:
- Clean skin before application; avoid harsh cleansers

- Use products regularly
- Ensure compatibility with other skincare products
Product selection depends on skin type:
- Oily skin: probiotics that regulate sebum
- Dry skin: prebiotics for moisture
- Sensitive skin: postbiotics with soothing properties
SAFETY AND QUALITY CONTROL
Safety is critical for microbiome cosmetics. Working with live microbes requires special
technology and strict quality control.
Manufacturing must comply with GMP standards: sterility, stability, and safety ensured.
Quality indicators:
- Microbe count and viability
- Lack of contamination
- pH level, osmolarity, product stability
Although allergic reactions are rare, patch testing is recommended, especially for sensitive skin.
CONCLUSION
The skin microbiome is revolutionizing dermatocosmetology. Scientific findings reveal its
complexity and value, inspiring a new generation of cosmetic products.
Probiotic, prebiotic, and postbiotic cosmetics have proven effectiveness, offering new solutions
for skin health and beauty. Future advances in technology and personalized care will enhance
results.
Microbiome cosmetics represent not only skincare products but a science-based dermatocosmetic
approach. This marks the beginning of a new era.
Ongoing research, personalization, nanotechnology, and AI will continue to shape the field,
offering opportunities for users of all ages.
