Pre And Probiotics For Skin

Pre/probiotic Skin Care: What Are They And Do They Work

Physio Radiance | QNETs Pioneering Healthy-Ageing Skincare Collection with Pre & Probiotics

Youve probably heard the words prebiotic and probiotic before. These buzzwords sound fancy and are touted as great aids for your digestive health, but what do they actually mean? And what do they have to do with skin care?

With prebiotic and probiotic skin care emerging as a hot new trend, we enlisted top dermatologists and skin care experts to learn more.

Intravaginal Administration Of Probiotics

A recent study evaluated the probiotic capacity of Saccharomyces cerevisiae CNCM I-3856 to modulate the expression of pathogenicity determinants by Candida albicans in vivo during vaginal candidiasis in experimentally infected mice. Besides, the administration of S. cerevisiae was evaluated for its influence on the number and functions of a landmark sign of inflammation in the host. In general, the study determined that daily intravaginal administration of S. cerevisiae CNCM I-3856 leads to the suppression of several fungal components that play critical roles in fungal virulence of C. albicans at the vaginal level. S. cerevisiae modulated the expression of aspartyl proteinases as well as hyphal growth-associated genes, Hwp1 and Ece1, in the vaginal cavity. The probiotic effects on the host and the probiotic suppression of neutrophils influx caused by the fungus into the vaginas of the mice are likely related to lower interleukin-8 production and inhibition of aspartyl proteinase expression. Besides, there was no evidence of any cytotoxic effect either by the probiotic, when used in vivo, on vaginal epithelial cell and organ architecture, or in in vitro in human vaginal epithelium .

Does Prebiotic/probiotic Skin Care Work

While prebiotic/probiotic skin care sounds promising, it’s still too early to definitively recommend it for certain skin issues, according to González. “We are just at the beginning of getting to understand their true impact,” she said.

At the same time, there have been encouraging signs that pre/probiotics could be helpful for certain skin issues.

“Some studies have shown that Nitrobacter has anti-fungal activity, and also combats bacteria known as Staphylococcus,” González continued. “Lactobacillus was shown to improve adult acne in a small study. Bifidobacterium in combination with Lactobacillus was shown to lower the incidence of eczema in early childhood. Streptococcus thermophilus has been shown to increase the production of ceramides in the skin, which could help in eczema.”

The bottom line? Prebiotic/probiotic skin care has the potential to be great for skin, but as with any other new trend, make sure you proceed with caution before diving right in.

How Does Topical Biotics Compare To Supplements

In contrast to skincare, ingestible pre/probiotic supplements are faced with entirely different conditions compared to the skin. Supplements must be able to withstand conditions of the varying conditions of the gut, which is very different to the surface of the skin, but like topicals, they must support good bacteria for optimal health and immune function.

Both the skin and the gut must protect us from the external environment and the microbiome balance plays a vital role in this protection. The skin and gut are connected and both the skin and gut microbiome work in synergy to improve immunity, fight harmful pathogens, reduce inflammation, and skin irritation, reduce stress, help control stress, balance metabolism and blood sugar, improve sleep and even elevate our mood!

Saccharomyces boulardii

A traveling French baker named Henri Boulard originally discovered this beneficial yeast. He noticed that natives eating fermented mango typically experienced overalll digestive health. Many believe this is due to the naturally occurring Saccharomyces boulardii. This beneficial, tropical species of yeast supports healthy gut transit time, along with healthy immune system and digestive function support.

Bacillus subtilis

A soil-based, spore-forming probiotic that supports normal microflora in the gut, healthy gut function, normal digestion and a healthy immune system, in addition to promoting a healthy GI tract and a healthy inflammation response. Naturally found in the environment and plants, they are hardy and typically have an evolved array of survival tactics. As one of the first bacteria to be studied, Bacillus subtilis also known as hay bacillus or grass bacillus typically has an extraordinary ability to survive harsh conditions, producing end-products allowing it to endure extreme conditions of heat, dryness, humidity and acidity in the environment

What Do Prebiotics And Probiotics Do For Your Skin

While there are tons of probiotics in your gut, thereâs also a community of them living on your skin too. There they carry out beneficial tasks like fighting off infections, maintaining a good pH balance, and keeping the skin protected and healthy.

While scientific research is still ongoing, the general consensus so far is that probiotics living on our skin are very beneficial to our skinâs health. Thatâs why, alongside the usual products containing cleansers or vitamins, youâll find skincare products with prebiotics .

Oral Administration Of Probiotics

The efficacy of orally administered capsules containing probiotics was evaluated in a randomized, double-blind, multicentric, placebo-controlled trial including 544 women older than 18 years of age diagnosed with vaginal infection . The test group and placebo group received either two probiotic capsules or two placebo capsules per day for 6 weeks. Women underwent two gynecological examinations after 6 and 12 weeks of the study. Differences between groups were significant at forty-four days after the initial visit the vaginal microbiota was restored in 243 women in the probiotic group compared to 40 women in the placebo group. After the additional 6 weeks of follow-up, normal vaginal microbiota was still present in more than half of the women in the probiotic group compared to only about one-fifth of those in the placebo group .

Gille et al. studied the effect of an oral probiotic food supplement in maintaining or restoring the normal vaginal microbiota during pregnancy. Three hundred and twenty women with less than 12 completed weeks of pregnancy participated in the study. Patients consumed a probiotic capsule containing L. rhamnosus GR-1® and L. reuteri RC-14® daily. The results showed that oral probiotics may be suitable for implementation in antenatal care but had no effect on vaginal health during mid-gestation.

As Zenhausern mentioned, our immune system needs good gut bacteria to function correctly. And its not the only system that benefits from a healthy microbiome. In addition to the immune system, good bacteria found in the gut can also ensure digestive health and that the hormonal system are in tip-top shape.

Probiotics and prebiotics work to ensure that the immune system, hormonal system and digestive system all function properly. And when that occurs, it can promote healthier skin. Because of its immune system support, taking these supplements for healthier insides can specifically improve inflammation of the skin. Inflammatory skin conditions such as acne and rosacea may be kept at bay by the use of probiotics, notes Dr. Debra Jaliman, a board-certified dermatologist in New York City. In addition, having a healthy gut microbiome can keep your skin glowing, says Dr. Zenhausern.

Dr. Jaliman is a fan of using probiotics topically, as it can impact the skin in a more direct wayand lead to more benefits. Recent studies have found that topical application of probiotics decrease skin sensitivity and redness and can result in a reduced appearance of fine lines, she notes.

How To Incorporate Prebiotics And Probiotics In Skincare

Our skin is a complex system of cells that serves life-giving functions ranging from regulating our internal temperature to protecting us from microbes. Skincare often focuses on treating the exterior of the skin with topical products, which can be helpful in reducing visible problems like aging, acne, or discoloration.

However, as our largest organ, its important that we focus on treating the skin from the inside out. We are familiar with the benefits of taking probiotics for gut health, organ functions, and boosting our immune system, but this healthy bacterium also plays a huge part in skin vitality, appearance, and health.

Oral Ingestion Of Probiotics And Prebiotics

As many healthy bacteria and microorganisms occur naturally in our gut, using probiotics to improve your digestive health has been an area that scientists and researchers have been increasingly interested in22.

To have a long-term, beneficial impact, foods rich in probiotics, like cheese and yoghurt, as well as prebiotic foods such as bananas, onions and asparagus, must be eaten regularly to continually supply the body with fresh bacteria. This is an important step in replacing the probiotics that have been broken down while reaching the gut23

What Are Prebiotics Probiotics And Postbiotics

New research has proven promising results that topical biotics will balance the skin microbiome and reduce skin surface damage and inflammation. Theres three biotics that I use in Dermiotic to offer a true skin balancer.


These are the food for the good bacteria, enabling the skin to function at an optimal level while inhibiting the bad bacteria.


These are live beneficial bacteria that support our skin and gut health.


This is a new term in science and has not been accepted fully in the research field with a scientifically accepted definition. This term describes the active by-products from lysates of probiotic bacteria. Postbiotics are like chopped up pieces of the probiotic bacteria, which offer the beneficial effects of probiotics but are more resistant to being destroyed in the bottle.

Postbiotics are the best way of delivering the benefits of good bacteria in a skincare product. I personally prefer to incorporate the postbiotic factors rather than live bacterial cells. These are molecules directly derived from probiotic bacteria but are not destroyed by the bacteria-killing preservatives in the skincare jars and bottles. It is basically a better way of delivering probiotic benefits.

Probiotic Probiotic And Postbiotic Skincare What Do They Do For The Skin

Pre-, pro- and postbiotics have become increasingly popular in skincare products lately, but most people dont have an exact idea what these terms stand for or if they are actually beneficial for the skin.

One thing all biotics have in common is that they address the skins microbiome, so if you have not read my article about that, make sure you are all caught up before you keep reading.

Today we want to have a look what the term prebiotic, probiotic and postbiotic means and which effects they have on the skin.

Skin Application Of Probiotics And Prebiotics

Applying a topical probiotic cream or solution to your skin can help to address the balance of healthy bacteria that make up your skin microbiome. The probiotics within these creams can help reduce the pH of skin, slightly acidifying the surface, to help promote the thriving of healthy bacteria on the skin24.

Prebiotic skin creams such as Aveeno® Dermexa Moisturizing Cream,can also be hugely beneficial. They help preserve the existing healthy bacteria on your skin when applied and encourage the survival of probiotic microorganisms already in your skin microbiome25. But thats not all. They also improve the balance of bacteria on your skin microbiome, contributing to a healthier skin ecosystem overall.

Both probiotics and prebiotics can play a major part in achieving a healthy complexion, as well as helping to relieve existing skin conditions. Give them a try by adding them to your daily skin routine, as well as your everyday diet. Look for products formulated with pre-biotic ingredients such as colloidal oatmeal. Prebiotic Oats not only keeps dry sensitive skin moist and smooth, but feeds your skins natural bacteria, keeping it in perfect balance.

Do Prebiotics Help With Acne

Acne is a skin condition that flairs up when the hair follicles become plugged causing whiteheads, blackheads or pimples, and usually appears on the face and upper part of the body. When the skin is too alkaline, it can be more susceptible to acne. A level of acidity is needed to prevent bacterial growth on the skin. At the opposite side of the spectrum, skin that is treated with products that are too acidic can over-strip natural oils, which can temporarily disrupt the lipid barrier of the skin and weaken the skins natural defenses. Your skin might start to look red, irritated, and more prone to breakouts. Prebiotics can help you maintain a healthy pH balance.

Introducing topical prebiotics, probiotics and postbiotics into your routine combined with the essential skincare ingredients such as vitamin A, niacinamide and vitamin C, consistency will reap rewards.

The three biotics should be essential to all skincare routines as our skin barrier is continuously being challenged by pollution, environmental toxins, and stress. Studies clearly demonstrate that topical biotic nutrition provide measurable ongoing skin benefits.

Using Probiotics And Prebiotics To Treat Skin Conditions

Pre biotic Skincare

The combined usage of probiotic and prebiotic solutions has been shown to treat certain skin conditions by positively impacting the skin microbiome and the microorganisms that live within that ecosystem17.

Both skincare solutions and foods that contain probiotics and prebiotics can be used to relieve variety of skin conditions, including:

  • Acne Studies have shown that topical solutions which contain the probiotic lactobacillus plantarum can help reduce acne lesions and repair the skin barriers of these suffering from acne18.

  • Eczema Scientific reviews have suggested that probiotic supplements, taken by mouth, can reduce the severity of those suffering from mild to severe eczema19.

  • Psoriasis Recent research has illustrated that certain strains of the probiotic lactobacillus can help reduce skin inflammation, showing promising signs that probiotics can control the effects of psoriasis20.

Iris says: Probiotics are beneficial for treating other skin issues, such as hypersensitivity, wound protection and repairing skin that has been damaged by the suns UV rays.21

What Is The Difference Between Prebiotics And Probiotics

Pre and probiotics both have their own vital role to play in the human body to ensure a healthy gut so the digestive system can work smoothly.

The role of prebiotics, which comes from indigestible carbs, is to act as food for good bacteria. The role of good bacteria is to feed off the indigestible fiber .

Another way to distinguish between pre and probiotics is: prebiotics are dead dietary fibers and probiotics are live bacteria.

Pre and probiotics are found in a variety of foods and also in supplements. Sufficient quantities of both pre and probiotics support ones health and promote the digestion of food and support a healthy immune system.

What Prebiotic Ingredients Should You Look For In Your Skin Care

Try to look for skin care products that are formulated with prebiotic ingredients like Xylitol, Rhamnose, Glucomannan, Oligosaccharides, Inulin etc.

A few of the other prebiotics-rich ingredients that you may find in skincare products include oat that helps in calming irritated skin, ginseng that reduces skin inflammation, pine that protects your skin from UV radiation.

How To Try Probiotic Skin Care

If a person decides to try probiotic skin care, they can do so by following these tips:

  • Start with a leave-on product, such as a moisturizer, from a reputable brand. A probiotic cleanser or soap will have less chance to work as these products are only on the skin for a short amount of time. Look for products that a third-party company has independently tested for safety and purity.
  • Try one new product at a time. Introducing multiple new products may make it difficult to tell which one is helping or if any are causing side effects.
  • Patch test the new product on a small area of skin first. If no symptoms develop within 24 hours, a person can try it on their face.
  • Apply the product to the face and monitor for any signs of irritation. If there are none, keep using the product for a few days to see how it feels and whether it has any effect. It can take time for skin care to make a difference.
