Role of Probiotics in Skincare

What are probiotics?

There are many different kinds of probiotic strains that the body produces and utilizes. Probiotics are essentially a bunch of microorganisms that live on your skin, as well as inside your body. What kind of combination of different probiotic strains you have determines how healthy you are, feel, and look. This combination is called the microbiome.

There are different activities that can disturb the delicate balance of the microbiome. Some of these include what you eat, as well as using harsh chemical skincare products. When the microbiome is disrupted and imbalanced it can translate to the skin. When imbalance, the skin may become more acne-prone, be irritated, or extremely dry.

What are the benefits of using skin probiotics?

Using skin probiotics regularly can help your skin in a myriad of ways, including:

  • Hydrated skin 
  • Less sensitive skin
  • A balanced skin pH
  • Reduced inflammation in the skin
  • More even skin tone and texture
  • Less acne

What skin probiotics to keep an eye out for?

Ideally, a high-performing microbiome consists of many different kinds of probiotic strain - no matter whether you’re ingesting them or applying them topically. The most common probiotics for your skin used in skincare products consist of Lactobacillus, Bifididaborium, and Vitroescilla. By using products with all of these, the health of your skin is ensured. Specific strains are helpful for different areas of your skin.

Lactobacillus ferment lysate

Lactobacillus ferment lysate is a lysate or by-product of fermenting the probiotic lactobacillus. In other words, it’s one of the probiotics in lactic acid. Certain lysates have been scientifically studied, and proven to improve skin. For example, the lysate of the lactobacillus rhamnosus has been shown to moisturize the skin and improve the skin barrier (Jung, Ye-On, et al, 2019). 

Lactobacillus ferment lysate is a commonly used ingredient in skincare products, that is deeply moisturizing and therefore is used a lot in anti-aging skincare, as well as great for sensitive skin as it is known to not cause irritation. It also helps block cells that are responsible for releasing inflammation, and therefore using skin probiotics can greatly reduce the inflammation in yours (Habeebuddin, Mohammed, et al, 2022). 

Lactobacillus ferment lysate also can help with collagen production (hello youthful glow!) and with wound healing (Habeebuddin, Mohammed, et al., 2022). So whether you simply want to look younger or have accidentally scratched yourself, Lactobacillus ferment lysate will be able to help out big time. 

Signs your microbiome is out balance

There are certain skin conditions that are associated with a non-diverse microbiome and can benefit from skincare probiotics. These can include rosacea, eczema, dermatitis, and acne can all be caused by a microbiome imbalance. Generally, extremely dry skin can be a sign of an out-of-whack microbiome. The good thing is that it’s a quick fix. You simply make sure that your body is receiving enough probiotics internally as well as topically, and your skin should improve shortly.
