Probiotic Lactic Acid Bacteria and Skin Health

Abstract

Human skin is the first defense barrier against the external environment, especially microbial pathogens and physical stimulation. Many studies on skin health with Lactic acid bacteria (LAB) have been published for many years, including prevention of skin disease and improvement of skin conditions. LAB, a major group of gram-positive bacteria, are known to be beneficial to human health by acting as probiotics. Recent studies have shown that LAB and their extracts have beneficial effects on maintenance and improvement of skin health. Oral administration of Lactobacillus delbrueckii inhibits the development of atopic disease. In addition, LAB and LAB extracts are known to have beneficial effects on intestinal diseases, with Lactobacillus plantarum having been shown to attenuate IL-10 deficient colitis. In addition to intestinal health, L. plantarum also has beneficial effects on skin. pLTA, which is lipoteichoic acid isolated from L. plantarum, has anti-photoaging effects on human skin cells by regulating the expression matrix meralloprotionase-1 (MMP-1) expression. While several studies have proposed a relationship between diseases of the skin and small intestines, there are currently no published reviews of the effects of LAB for skin health through regulation of intestinal conditions and the immune system. In this review, we discuss recent findings on the effects of LAB on skin health and its potential applications in beauty foods.

Efficacy of Using Probiotics with Antagonistic Activity against Pathogens of Wound Infections: An Integrative Review of Literature

“…Some studies [82,147] have found that postoperative consumption of probiotics (mainly L. plantarum 299) per os improves immune response, reduces the number of postoperative infections, and reduces hospitalization time and the amount of prescribed antibiotics. All of these studies conclude that postoperative endpoints should continue to be thoroughly investigated, and two studies went on to highlight the great potential of topical use of probiotics to protect the wound [15,17].…”

“…Using various state-of-the-art molecular and genetic-based methods, it was found that the skin microbiota is dominated by bacteria from the phyla Actinobacteria, Firmicutes, Proteobacteria, and Bacteroidetes; resident genera mainly include Propionibacterium spp., Staphylococcus spp., Micrococcus spp., Corynebacterium spp., and Acinetobacter spp. and the main representatives of the fungi being species of the genus Malassezia [15][16][17][18]. e diversity of skin microbiota among individuals depends on age, diet, gender, and environmental and geographical factors.…”

Lactic acid bacteria with cholesterol-lowering properties for dairy applications: In vitro and in situ activity

“…Plant stanols and sterols, which lower serum concentrations of cholesterol, have been incorporated into foods, but they are expensive (Law, 2000). Over the years, the probiotic activity of lactic acid bacteria (LAB) has been studied (Collins, 2014), and LAB have been associated with improved lactose intolerance, increased natural resistance to infectious disease in the gastrointestinal tract, the suppression of cancer, and better digestion and skin health (Lye et al, 2010;Clarke et al, 2012;Kanmani et al, 2013;Zhong et al, 2014;Jeong et al, 2016). Moreover, Mann and Spoerry (1974) and Shaper et al (1963) evidenced the hypocholesterolemic effects of a diet containing LAB strains, and it has been proven that some LAB can lower total cholesterol and low-density lipoprotein cholesterol levels (Zeng et al, 2010;Ishimwe et al, 2015).…”

Effects of intake of <i>Lactobacillus casei</i> subsp. <i>casei</i> 327 on skin conditions: a randomized, double-blind, placebo-controlled, parallel-group study in women

“…Moreover, the health-promoting activities of lactic acid bacteria are species- and strain-specific [10]. Thus, use of a variety of lactic acid bacteria as a dietary supplement has been investigated extensively [11], and interest in the use of lactic acid bacteria for improvement of skin conditions has been growing [12]. Some reports show beneficial effects on atopic dermatitis or allergic rhinitis [13, 14], skin aging [15], and acne [16].…”
