Glossary
A genus of beneficial bacteria commonly used in probiotic skincare products to support the skin's microbiome. Bifidobacterium lysates and ferments are incorporated into topical products to strengthen the skin barrier, reduce inflammation, and promote a healthy balance of microorganisms on the skin's surface.
Your skin hosts trillions of microorganisms, collectively called the skin microbiome, that play a crucial role in immune defense, barrier function, and inflammation regulation. When this microbial community is balanced, your skin is better equipped to resist infection, heal from damage, and maintain moisture.
Probiotic skincare aims to support this microbial balance. Bifidobacterium, one of the most studied probiotic genera, produces compounds that inhibit pathogenic bacteria, strengthen the proteins that hold skin cells together (improving barrier function), and modulate the immune response to reduce chronic low-grade inflammation associated with conditions like eczema and rosacea.
Interestingly, traditional natural skincare ingredients like raw honey and propolis have been supporting the skin microbiome for centuries before the term was coined. Raw honey contains prebiotics (food for beneficial bacteria), has antimicrobial properties that selectively target harmful bacteria while sparing beneficial species, and creates an environment that supports a healthy microbial balance.
This is one reason why switching from synthetic skincare products to natural, beeswax-based products often results in improved skin health over time. Rather than stripping the skin of all bacteria (as many antibacterial cleansers do), natural ingredients work with the microbiome.
The concept is similar, but topical probiotics are formulated differently. Skincare probiotics typically use bacterial lysates (broken-down bacteria) or ferment filtrates rather than live cultures. These preparations deliver the beneficial compounds without the stability challenges of keeping live bacteria in a cosmetic product.
Probiotic skincare is complementary, not a replacement. A solid foundation of gentle cleansing, adequate moisture (beeswax, shea butter, plant oils), and sun protection provides the environment in which a healthy microbiome can thrive. Probiotics may offer additional benefits for specific concerns.
Yes. The oligosaccharides in raw honey serve as food for beneficial bacteria on the skin, qualifying honey as a prebiotic. This is one of the mechanisms through which regular topical honey application supports skin health.
