Skin is the largest organ in the body, which gives us natural beauty. It is our external protective system. Skin is continuously exposed to several factors that are ready to compromise health. Factors that are physical, chemical, bacterial, fungal, even mechanical factors are all around to continuously influence the health of the skin. An issue on the skin has a lot to tell with regards to our whole physical, mental, and psychological health status. Microbes are ubiquitous in the environment. We are exposed to them regularly, thus hosting them. Their composition is somewhat complex and influenced by several factors. Probiotic Skincare became a bandwagon. Many hypes, posts, and news have now stimulated the interest of many to explore further what probiotic skincare entails. Everyone in skincare is now talking about this.
There is some microorganism population that offers great benefits to us. Those bacteria populations reinforce the natural skin barrier against the terrifying bacteria groups, help balance the skin's pH levels, and protect against some forms of skin cancer. Probiotics have been found to play all these important roles to help salvage most of the effects caused by those exposures. It has great potential to prevent or treat different skin diseases which range from eczema, atopic dermatitis, acne, or allergic inflammation. Photoaging caused by exposure to ultraviolet rays is reduced significantly by probiotics. Photoaging is a significant issue since it causes a different form of skin damages. While trying to enhance our skin beauty with the use of harsh facial cleanser or antibacterial soaps, we might have stripped the skin of these groups of healthy bacteria hence damage the skin's microbial ecosystem. Those changes also contribute to more stress on the skin, leads to dryness, , eczema, rosacea flares, or psoriasis.
How do probiotics benefit skin?
First, we need to understand that there are different strains of probiotics. The most common ones are Lactobacilli and Bifidobacterium. There are several other species with specific roles. Just like the probiotics supplement capsule we swallow, when probiotics are formulated to make creams, they help achieve a form of biome balancing status on the skin by regulating the natural balance, moderate the cell's signaling molecules to increase cell communication hence a well-equipped immune system. This all helps act as a protective mechanism to prevent the bad microbes from provoking immune reactions, thus creating a calm environment on the skin. This immune mechanism complemented by probiotics helps boost the skin response in managing external factors such as the damaging effects of ultraviolet rays, free radicals, and pollution. Those responses help reduce flare-ups and prevent premature aging. Probiotics have a fortifying power to helps in providing calmer skin and control over the breakouts caused by conditions such as rosacea and eczema. Probiotics foster the process of skin hydration with improvement in hair follicles.
The process of repair for sensitive skin is usually a prolonged process that is usually fast-tracked by probiotics. There are specific probiotics that are indicated in the management of atopic dermatitis hence prevent the symptoms. This is achieved by influencing the biological process associated with eh atopic dermatitis. A study by Vasiliki & Mihalis (2019) recently confirmed the role of probiotics species of L. rhamnosus and L. reuteri in improving the severity of eczema by 56% in children suffering from atopic dermatitis (AD). L. fermentum is also indicated in skin Infections (wounds), increases the production of IL-1 4 and TGF-β, and five cytokines. B. bifidum is found to be important in the improvement of Atopic Dermatitis, Acne, which is achieved by reduction of Ig-E.
Probiotics also prevent loss of elasticity by suppressing the production of elastase. The microbes reduce inflammation areas, enhance the production of bacteriocins (lactic acid, acetic acid, hydrogen peroxide, bacteriocins) or promotewounds healing . Probiotics also help in the Inhibition of S. aureus, S. salivarius, S. pyogenes, P. aeruginosa, C. Albicans, S. Typhimurium, L. monocytogenes, and E. coli growth.
The roles of probiotics on skins can be summarized as immune system stimulation, anti-inflammatory properties, transcriptional activation/suppression, block integrin, reduce MRSA, prevention of TEWL, production of bacteriocins, inhibition and enhancement of gene expression, and competitive exclusion.
Probiotics have been used by medics to achieve greater things in the body. There are studies conducted to understand the diversified roles played by probiotics. Probiotic skincare has efficiently utilized various benefits and processes of probiotics to achieve good skin health and enhancement of women's beauty.
