Digging into the beauty and health benefits of probiotic skin care
Posted on September 8, 2025 Written by: 100% PURE®

How much do you know about probiotic skin care? It’s a relatively new craze that has been growing in popularity over the last couple of years, and chances are you’ve already been using natural skin care products with probiotics, without even knowing it. If you aren’t even sure what a probiotic is, don’t worry, we’ll fill you in on all the juicy deets. And if you aren’t totally convinced a probiotic is right for your skin, keep reading! We’ll explain why probiotics are proven to work, how they help our skin, and how even vegan probiotics can help any skin type when used in natural skin care products.
What’s a Probiotic, and Why Is It in My Skin Care?
So what is a probiotic, anyway? Ultimately, it’s just a fancy term for healthy bacteria. Probiotics are generally produced when certain kinds of dairy liquids, like milk or yogurt, are fermented. Probiotics are then extracted from the liquid, and converted into a supplement or added to other foods. A probiotic helps reintroduce and stimulate local bacteria that have a positive effect on the body. Most often taken as a vitamin for gut health, the discovery that topical probiotics are great for skin health is somewhat new. Still, this new natural skin care ingredient is taking the beauty world by storm. We know it’s hard to imagine that bacteria on our skin can actually be a good thing, but keep your mind open while we break it down for you!
Enter the microbiome. Remember the movie Osmosis Jones, where the body was turned into a complex world of cells and bacteria? That’s sort of how we imagine the microbiome, which is basically the community of bacteria living on our skin. Obviously, we can’t deny that some types of bacteria are bad. Acne-causing bacterias from sweat and dirt can turn our smooth skin into a breakout zone overnight. But don’t judge every bacterium by its name! Some bacteria on the skin can actually be a good thing, because they help to fight off the bad bacteria that cause premature aging, breakouts, and imbalanced skin. If maintaining a healthy diet and drinking plenty of water has such a powerful effect on skin care, you can bet that probiotics (both ingestible and topical) have just as strong of a bond with clear skin.
Probiotics and Fermentation
Fermented Foods
Fermentation is very closely linked to probiotics, and is a helpful ally in the quest for both internal and external health. Some of our favorite foods, including cheese, sourdough bread, beer, and many more are actually made through fermentation. Fermentation is the process of introducing healthy bacteria to break down the sugars or acids in a product. Fermented foods can be good for us because they filter into the digestive tract of our bodies. Introducing healthy bacteria via fermented foods supports the natural processes of our immune systems. This contributes to better digestion, better filtration of toxins out of the body, and of course, better skin. Since most probiotics are processed via dairy and are not vegan, great probiotic options for those of us on vegan diets include kombucha, tempeh, miso, kimchi, and non-dairy yogurt.
Fermented Natural Skin Care
As we mentioned, eating fermented foods supports our immune system’s ability to process out toxins. How does this relate to healthy skin? Well, toxic bacteria are most often to blame for many of our skin woes. When our immune system filters out toxins for us, it allows our skin to relax a little bit and results in smoother, happier skin. Toxic skin bacteria can throw off our skin’s pH balance or oxidize our skin cells, causing damage that results in dull or aged looking skin. Applying fermented products or probiotics topically will support the process of detoxifying the body and the skin, which is already happening in our digestive system from consuming probiotics. When our skin’s surface – the microbiome – is in healthy harmony, the remaining healthy bacteria keeps our skin looking and feeling its best.

Your internal and external health need balance to remain healthy, and a good probiotic boost may just be what you’re missing!
The Connection Between Probiotics and a Balanced Skin pH
When we think of skincare, we often focus on hydration, anti-aging ingredients, and acne treatments—but one often overlooked factor in maintaining healthy skin is pH balance. Your skin’s pH determines how well it can protect itself from harmful bacteria, retain moisture, and resist irritation. A healthy pH for skin typically falls between 4.5 and 5.5, slightly acidic to ward off pathogens and support barrier function.
Probiotics can play a critical role in restoring and maintaining this balance. When the skin’s microbiome is compromised—due to over-exfoliation, harsh cleansers, pollution, or antibiotic use—the pH can become unbalanced, making skin more prone to redness, sensitivity, breakouts, and dryness. By reintroducing beneficial bacteria through probiotic-infused skincare, we help repopulate the skin’s surface with microbes that support optimal acidity and a healthy barrier.
This not only helps calm irritation and reduce inflammation but also strengthens the skin’s defenses over time. Probiotics may also inhibit the growth of harmful bacteria that thrive in higher pH environments, making them especially beneficial for those with acne-prone or sensitive skin.
If you’ve ever experienced tight, itchy, or overly reactive skin after using a “cleanser that’s too clean,” there’s a good chance your pH was thrown off. Adding probiotics to your skincare routine—particularly in leave-on treatments like serums, essences, or moisturizers—can help recalibrate your skin’s pH and leave it feeling soothed, resilient, and balanced.
Frequently Asked Questions About Probiotics in Skin Care
1. What do probiotics do for the skin?
Probiotics help balance the skin’s microbiome—the ecosystem of bacteria, fungi, and other microorganisms that live on the skin. When applied topically, probiotics can strengthen the skin barrier, reduce inflammation, and help defend against environmental stressors. They also promote the growth of beneficial bacteria, which can crowd out harmful bacteria that cause acne, irritation, and sensitivity. As a result, probiotics can improve hydration, calm redness, reduce breakouts, and support a clearer, more balanced complexion.
2. Are probiotic skin care products good for acne?
Yes, probiotic skincare can be beneficial for acne-prone skin. Breakouts are often caused or worsened by an overgrowth of acne-causing bacteria (such as C. acnes). Probiotics work by introducing beneficial bacteria that restore microbial balance and reduce inflammation. This can help reduce the severity and frequency of acne flare-ups. Additionally, probiotics may strengthen the skin’s barrier, helping to prevent future breakouts triggered by environmental aggressors, stress, or hormonal fluctuations.
3. Can I use probiotic skincare if I have sensitive skin?
Probiotic skincare is often ideal for sensitive skin because it focuses on restoring balance and calming inflammation. When the microbiome is disrupted, the skin is more likely to react to ingredients or environmental factors. Probiotics can soothe the skin by reinforcing the barrier and reducing hypersensitivity. However, as with any new skincare product, it’s important to check for other ingredients in the formula and perform a patch test before full application.
4. What’s the difference between probiotics, prebiotics, and postbiotics in skincare?
- Probiotics are live beneficial bacteria applied topically to support a balanced skin microbiome.
- Prebiotics are nutrients (like plant sugars or fibers) that feed the good bacteria already on your skin, helping them thrive.
-
Postbiotics are the byproducts or metabolites of probiotics, such as peptides, enzymes, and acids, that provide antioxidant, anti-inflammatory, and barrier-supporting benefits.
In skincare, many products combine these for a synergistic effect, helping support the skin’s overall health from multiple angles.
5. Are all probiotic skin care products vegan?
Not necessarily. Many probiotics are derived from dairy-based fermentation processes, such as those involving milk or yogurt. However, vegan probiotics do exist—they’re derived from plant-based fermentation processes using ingredients like rice, seaweed, or vegetables. If you’re following a vegan lifestyle, look for products specifically labeled as containing vegan probiotics or fermented botanical extracts. Always check ingredient lists and certifications to ensure the product aligns with your values.
