Could Probiotics be the Ultimate Cure for Acne?

March 08, 2018

Probioticsis a term used to describelive microorganisms that areconsidered beneficial for our health, although the term is generally reserved only for the bacteria and yeasts that we ingest in foods or supplements. But probiotics are also loosely defined in topical applications, as well.

Using probioticsinternally and topically to treat acne and other skin conditions are both recent trends in the skin care industry, leaving some wondering if probiotics have the potential to be theultimate cure for acne that we’ve been waiting for.Whilewe’ve talked abouteating moreprobiotics,whichmay or may not improve acne symptoms, the potential for probiotics to work at the site of application is too exciting tojustgloss over!


how do probiotics work?


If probiotics are going to be theultimate cure for acneweat leastneed to understand how they work for our skin’s benefit.

Skin, the largest human organ, is a complex and dynamic ecosystem, inhabited by manythousands ofmicroorganisms. And while genetics, behavior, environment and other events may drive variability in our skin microbiota, probiotics are believed to optimize, maintain and restore the microbiota indifferent ways.

Ingested probiotics help to keep your gut healthy by lining the digestive tract and supporting your body’s ability to absorb nutrients and fight infection.

Topical applications have amoredirect effect at the site of application by enhancing the skin’s natural defence barriers. Probiotics andotherresident bacteria produce antimicrobials that benefitour skin’s immune responses and eliminate pathogens.

There are many probiotic products out there that stake the claim of clearing up acne and other skin conditions, butas of now, none have received therapeutic treatment status.

In terms of skin care products, there are several topicalapplications on the market right now touting probiotic benefits. These include brands like Tula,GloBiotics,BioElements, Eminence and Epicuren,all of which list anywhere from one to three strains of beneficial bacteria in certain products.

If youtake a peek at some of the products these companies offer, you’ll notice that probiotic skincare is no cheap acne treatment – but some say the results are worth the cost because it really is theultimate cure for acne!

If youlook at the anecdotal reviews of probiotic supplements on a whole, you see a pretty striking rate of highly satisfied customers! People truly cherish their probiotics, and some even credit their supplementation for improving various conditions and their overall health.While most people claim an improvement in digestive symptoms only, some even go so far as to suggest these supplements improved their skin. But do these anecdotes really stand up to the test?

At this time, wejustdon’t have a lot of research to go on, but there are some observations we can make.

One randomized, double-blind, placebo-controlledstudy of 56 children aged 6-18 months with moderate or severe atopic dermatitis found that those who receivedL fermentum probiotic supplements had improved severity in symptoms.Anotherstudy also found thattwootherstrains also improved atopic dermatitis symptoms in children. However,afollow-up of the second study,found thatLactobacillusrhamnosusandBifidobacteria lactisimproved atopic dermatitis, but only in food sensitized children.

Ameta-analysis (a large review of studies) evaluated the use of ingested probiotics on the improvement of eczema symptoms in children, and found probioticsto be an ineffective treatment option.

While atopic dermatitis and eczema aren’t acne, these studies may help shed light on the direction we can expectacne-oralprobiotic research to go.

Still, with studies showing otherpositive effects from usingoralprobiotics, it’s still unclear whether the benefitswouldoutweigh the known (and potential) risks.


topical probiotics and acne


While I believe that oral probiotics have some potential as health-promoting supplements, if we can advance our knowledge a bit more, I hold much more hope for topical applications of probiotics, and for good reason.

The first report that topical use of probiotics may be helpful in acne and other skin conditions was published in 1912, but until more recently we haven’t had much hard evidence.

To start,wenowknow that dysbiosis in the skin’s microbiome can lead todisease. Probiotics have beenshown to alter the skin’s microbiome, improving the moisture barrier andimpedingP. acnesbacteria through the production of antibacterial proteins.Topical application could even result in a50% -89% reduction in acne papules and pustules, inbothnumber and severity. Anotherstudy similarly found that topical probiotics work by inhibiting the skin’s colonization by “bad bacteria”, and by producing potent antimicrobials that preventpathogen adhesion. I am all for preventative medicinein skin care!

In several other studies,acream containingStreptococcus thermophilescaused anincrease in ceramide production in the skin, whichworkstoimprove the skin’s barrier. Not only did the cream amp up the production ofceramides, which play an essential role in the skin’s water-holding abilities, but patients alsodirectlyexperienced less skin itching, redness, dryness and flaking as a result.

Probiotic bacteria also produce acidic compounds like lactic acid, known to be beneficial for the skin, which then acidifies the skin and discourages the growth of certain pathogens whilepromoting “good bacteria”.

By decreasing the amount of P. acnes on the surface of the skin, and inducing the production of healthy ceramides, topical probiotics can restore important fats which can benefit acne directly, andcounter common side effects resulting from acne therapies.

Otherpapers have focused on the potential for topical probiotics to be used inotherwound healing and infection, with promising results.

Looking at the research in an overview, it seems pretty clear to me that topical probiotics, particularlycertain strains, hold enormouspotential in skin care and thetreatment of skin issues like acne.


a note on strains


Everything I’ve ever encountered with probiotic research has emphasized the importance and diversity in species, and in strains. Most studies can only focus on a few of the thousands of species, and a few of their potential strains. Therefore, we can expect the research to be slow and painful. But just because current research doesn’t indicate a strong benefit from probiotic supplementation at this point, doesn’t mean there isn’t the potential for future research.

Some people, like myself, believe bacteria to hold far more potential than we have yet recognized, and so, hold out for promising research in the years to come.


the ultimate cure for acne?


So,are probioticstheultimatecure foracne?

For many people, probably not – the pathophysiology of acne isoften much more complex thanjust what’s onthe skin’s surface.The literature on probiotics,though very promising,isstill in its infancy.But could using probiotics still drastically help some people – people with damaged or dehydrated skin, for example? I certainly think so. In fact, in my humble opinion, I think probiotics may hold the potential to change skin and health care as we know them. With antibiotic resistance on the rise, andthe body of evidence on the importance of microorganisms growing, the time isupon us to start heavily entertaining these promising alternatives. I think microbiology and germ studiesstillhave a lot left to teach us.
