Summary
Cosmetic products can disrupt the skin microbiota, a beneficial microbial community. Standardized testing is crucial to ensure cosmetics are skin microbiota-friendly and prevent skin health issues.
Area of Science:
- Microbiology
- Cosmetic Science
- Dermatology
Background:
- The skin hosts a vital microbial ecosystem, the skin microbiota, crucial for human health.
- Cosmetic products interact with this ecosystem, potentially causing imbalances.
- Understanding these interactions is essential for cosmetic safety and efficacy.
Purpose of the Study:
- To review the significance of the skin microbiota in the cosmetic industry.
- To highlight the impact of cosmetic ingredients on skin microbial balance.
- To emphasize the need for standardized testing of cosmetic products.
Main Methods:
- Review of existing scientific literature on skin microbiota and cosmetics.
- Analysis of studies investigating the effects of cosmetic ingredients on microbial communities.
- Evaluation of different methodologies used to assess cosmetic impact on skin microbiota.
Main Results:
- Cosmetic ingredients can disrupt the skin microbiota equilibrium.
- Disruption may lead to skin diseases and immune system dysregulation.
- Methodologies for assessment vary and must be chosen carefully based on study aims, skin site, and target population.
Conclusions:
- Testing cosmetic impact on skin microbiota is critical.
- Standardized procedures and criteria are needed to identify 'skin microbiota friendly' products.
- This ensures product safety and supports skin health.

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
