Summary
Lactobacillus extract effectively treats mild acne. A 5% concentration improved skin barrier, reduced redness, and decreased acne lesions by impacting skin microflora.
Area of Science:
- Dermatology
- Microbiology
- Cosmetic Science
Background:
- Human skin possesses natural antimicrobial defenses against pathogens.
- Lactobacillus plantarum, a gram-positive bacterium, produces antimicrobial peptides with anti-inflammatory and skin-enhancing properties.
Purpose of the Study:
- To evaluate the efficacy of lactobacillus extract in improving skin barrier function.
- To assess the reduction of erythema and skin microflora.
- To determine the impact on acne lesions.
Main Methods:
- Clinical studies were performed to test lactobacillus extract on skin.
- Evaluated effects on skin barrier, erythema, microflora, and acne lesions.
- Compared efficacy of 5% and 1% lactobacillus extract concentrations.
Main Results:
- Lactobacillus extract at 5% concentration demonstrated significant reduction in skin erythema.
- The 5% extract was effective in repairing the skin barrier and reducing skin microflora.
- A notable decrease in acne lesion size and erythema was observed with the 5% concentration.
Conclusions:
- Lactobacillus extract at a 5% concentration is a viable treatment for mild acne lesions.
- The extract enhances skin's antimicrobial properties and barrier function.

01:22Probiotics
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:18Surface Membrane Barriers
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...

01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
