Beyond the Gut: Here's Why Everyone in Skincare Is Talking About the Microbiome

I don’t know when probiotic skincare came into my consciousness, just like I don’t know when every woman in L.A. and NYC started wearing the same animal-print silk midi skirt. I only know that one day, both things became ubiquitous on social media feeds. As someone who doesn’t have Instagram, I was getting screenshots of ads for various probiotic skincare lines in my email inbox from friends with a consistent subject line: “Thoughts?” All of a sudden, probiotic skincare became a bandwagon, and I’ve never met a bandwagon I didn’t want to jump on.

As I researched in-depth, I learned that this is less of a bandwagon, and more of a movement. I’ve always known about the body’s and gut’s microbiome, but the skin’s microbiome was relatively new to me. It had come up once or twice during my extensive research into perioral dermatitis, but nothing was mainstream.

Then, last month, I saw a surprising body wash commercial playing on TV at the gym. “What is the microbiome?”, the voice in the ad asked viewers. After just half-a-year of research and reading medical journals on the skin’s microbiome, I was thrilled that the microbiome movement was going mainstream.

Now that probiotic skincare is cluttering the inboxes of beauty editors, consumers, and department store shelves, I’m here to explain exactly what the skin microbiome is, why you need to know about, and how probiotic skincare really works.

What are prebiotics, probiotics, and postbiotics?

 Can you remember the first time you heard about probiotics? That’s something that I can recall. I was eight years old and my Russian grandmother was force-feeding me pickled cabbage with a spork because I wasn’t feeling well. She said it had good bacteria to fight off the bad. While the words “microflora” and “gut bacteria” were still out of my lexicon until I moved to L.A., I always had a vision that various bacteria were needed to keep each other in-check.

When I moved to L.A., often recognized as the new age health mecca of the world, the importance of good gut health was seared into my brain like grill marks on a steak.

Now we’re into not only probiotics, but prebiotics and postbiotics, too. What’s the difference? This is a very common question, so I’m going to break this down as simply as possible. In their journal on The Therapeautic Use of Prebiotics, Probiotics, and Postbiotics to Prevent Nectrotizing Entercolitis, Dr. Ravi Patel and Dr. Patricia Denning identify the key distinctions:

1.    Prebiotics: Supplements or foods that contain a non-digestible ingredient that selectively stimulates the growth and/or activity of indigenous bacteria.

2.    Probiotics: Supplements or foods that contain viable microorganisms that alter the microflora of the host.

3.    Postbiotics: Non-viable bacterial products or byproducts from probiotic microorganisms that have biologic activity in the host.

Now that we know that prebiotics are like the fertilizer for microorganisms to grow, probiotics are the microorganisms themselves, and postbiotics are the chemical byproducts of microorganisms and bacteria, let’s discuss how they’re useful in skincare.

What is the skin microbiome?

“The skin microbiome is the billions of bacteria, fungi, and viruses that comprise the skin microbiota,” says New York dermatologist Dr. Marnie Nussbaum, who recently attended Paris’ Microbiome Summit for doctors and microbiologists. “The human skin has 1 billion microbes (bacteria) per square centimeter and that natural bacteria maintains the skin’s immunity and prevents pathogenic growths like atopic dermatitis (eczema) and psoriasis.” When a healthy composition of microorganisms and bacteria on the skin is disturbed, Dr. Nussbaum tells me, the skin becomes vulnerable to an overgrowth in pathogenic bacteria, increased inflammation, and an altered skin pH.

Essentially, the more strains of bacteria you have, the healthier your skin is.

In Europe, studies show microbiologists are culturing strains from healthy skin and diseased skin to draw comparisons in bacterial differences. Then, they replace the bacterial strains that diseased skin is lacking for long-term treatment study.

What causes the skin to be disturbed? Dr. Nussbaum explains that doctors and scientists most often attribute dysbiosis to harsh hygiene (like over-exfoliation and lathering soaps with antibacterial properties), the use of topical antibiotics, and evolution. The result of having a disrupted microbiome? Bacterial and fungal skin rashes like eczema, psoriasis, perioral dermatitis, seborrheic dermatitis (dandruff), pityrosporum folliculitis (pesky bumps on the chest and forehead), tinea versicolor, and acne–to name a few.

Thus, adding bacteria to the skin and using gentle products to help maintain its balance seems essential to good skin health. Enter: microbiome skincare. Though it can be used interchangeably with probiotic skincare, there is a subtle difference. Dr. Nussbaum clarifies, “Probiotic skincare typically uses actual probiotic elements for a therapeutic effect, versus microbiome-friendly products, which are more of a gentle or sensitive characteristic that won’t disrupt the microflora."

“Science is the future of skincare,” Christin Powell, product formulator and co-founder of Kinship, tells me as she describes her new brand’s approach to affordable microbiome-friendly skincare. At the heart of each of the brand’s products is a proprietary combined prebiotic and probiotic from fermented lactobacillus, one of the most common families of bacteria found in probiotics. The brand calls it The Kinbiome. Powell tells me the brand hopes to target teens and young adults who are just beginning to learn about and deal with acne treatments. It’s at this young age that people first start using harsh chemicals and ingredients to strip oil production and inflammation, instead of understanding the skin's microbiome and using products to restore the healthy balance of bacteria.

As far as the probiotic skincare and microbiome movement as a whole, Powell says, “It’s just starting; this is the tip of the iceberg.” Mark our words: you're going to start seeing a lot of microbiome and probiotic-focused skincare in 2020 and beyond.

For this brand, bacteria are definitely a way of life.
