In recent years, probiotics and fermented ingredients have moved out of the kitchen and into the world of cosmetics. What once seemed like a food trend, such as kombucha, kefir, or kimchi, is proving to be an interesting ally for the skin as well. Scientific studies confirm that probiotics, prebiotics, postbiotics, and fermented ingredients can help strengthen the skin's barrier, rebalance the skin's microbiome, and boost the complexion's radiance. It seems, therefore, that this is not just a passing trend, but a new way of caring for the skin by focusing on its natural balance.
Probiotics in skincare: benefits for the skin and the face
@tiffanycglow I’m so happy I found probiotic skincare in 2021. It was the start of my acne healing journey. Whenever I experience breakouts now, I go back to using these products. #probioticskincare #skinbarrierrepair #skinmicrobiome #acnetips #acneprone #acneskincare #acnetreatment original sound - djparry
Probiotics are those good bacteria that are beneficial to both our bodies and our skin. You’re probably familiar with them from yogurt or kefir, which help with digestion and keep the gut in balance. Well, on the skin, they do something very similar. They help the skin microbiome (a kind of invisible ecosystem that lives on our skin) stay in harmony. When this balance is present, the skin shows it: it’s brighter, less reactive, it reddens less easily, and tends to have fewer imperfections or dry patches. In practice, probiotics give the skin a hand in defending itself and staying healthy.
Probiotics vs prebiotics: what’s the difference?

If probiotics are the good bacteria that help maintain skin balance, prebiotics are their favorite food. Prebiotics are not bacteria, but natural substances, like fibers or sugars, that nourish and strengthen the good bacteria already living on your skin. It’s a bit like giving someone the energy to do their job well. Together, probiotics and prebiotics strengthen the skin barrier, helping the skin stay balanced, more resilient and hydrated.
And what about ferments and fermentation?
@kristingl Fermented skincare options! For those who already love it or those newcomers who don’t know where to start. Fermented ingredients can be a great way to soothe, hydrate, and reinforce your skin barrier. They’re also more potent than their non-fermented counterparts.
Ferments in skincare are a bit like probiotics, but with an extra boost. Natural ingredients like rice, soy, or ginseng are processed by bacteria and yeasts through fermentation. This way, the active compounds in these ingredients become easier to absorb by the skin and even more effective, like they’ve gotten a natural upgrade. Additionally, ferments are rich in antioxidants and vitamins that nourish deeply. In short: while probiotics and prebiotics work to maintain balance in the skin’s microbiome, ferments also act as true superfoods for the skin, helping it stay more hydrated and protected.
Who can use these ingredients?
The truth? A little bit of everyone, but certain skin types will benefit even more. If you have sensitive skin, prone to eczema, irritation, or rosacea, that reddens easily or irritates with even the slightest temperature change, these actives can help a lot. They strengthen the skin barrier and calm the skin, making it less reactive day by day. They’re also perfect if you have combination or impure skin, with acne or blemishes. Probiotics, prebiotics, and ferments help rebalance the microbiome, reducing inflammation and promoting a more even complexion. Even if you have dull skin, you can benefit from these: ferments, in particular, provide a nice boost of energy and radiance, thanks to vitamins, antioxidants, and active compounds. In short, whether you want to calm, rebalance, or revitalize your skin, these ingredients are true allies.
