When it comes to skin and gut health, you've probably heard the terms "probiotics" and "antibiotics" used often — sometimes even interchangeably, even though they work in very different ways. Here's a straightforward look at what each one actually is, where they came from, and how they fit into a modern wellness routine.

Key Takeaways
- Antibiotics are prescription medications that target or limit the growth of certain microorganisms, used under a doctor's guidance.
- Probiotics are beneficial bacteria and yeasts naturally found in fermented foods like kefir, yogurt, and cheese.
- They aren't competitors — they serve different purposes in overall wellness.
- Researchers are still exploring how the gut microbiome may connect to skin appearance (the "gut-skin axis"); this research is ongoing and doesn't establish that probiotics treat any skin condition.
- Anyone with underlying health conditions, who is immunocompromised, or who takes other medications should check with a healthcare provider before adding a supplement.
A Brief History of Antibiotics
The German physician Paul Ehrlich is often credited with developing one of the first antibiotic compounds in the early 20th century, calling his approach "chemotherapy" — from the Greek for "chemical treatment." Decades later, Dr. Selman Waksman formally coined the term "antibiotics" after discovering numerous antibacterial compounds of his own.
Antibiotics work by targeting and limiting the growth of certain microorganisms. Since their discovery, many generations of antibiotics have been developed for a wide range of uses. Antibiotics are prescription medications, and any decision about using them — for any condition — should be made with a healthcare provider.
What Are Probiotics?
The word "probiotic" comes from the Latin for "for life." Probiotics are beneficial bacteria and yeasts naturally present in fermented foods like kefir, yogurt, and cheese — and some historians trace their presence in the human diet back thousands of years.
Probiotics have been studied most extensively for their role in digestive health, where they support a balanced gut microbiome — the community of microorganisms living in your digestive tract. Researchers continue to explore how this gut environment may connect to other areas of wellness, including skin appearance, through what's sometimes called the gut-skin axis.*
Different probiotic strains are being studied for different potential roles. For example, early research has looked at strains like Lactobacillus plantarum and Lactobacillus paracasei in relation to skin's appearance, though this research is ongoing and doesn't establish that probiotics treat any skin condition.
Most probiotics are naturally occurring, widely available, and generally well tolerated, though mild effects like bloating or gas are possible. As with any supplement, people who are immunocompromised should speak with a healthcare provider before taking probiotics.
Two Different Tools, Two Different Purposes
Antibiotics and probiotics aren't really competitors — they serve different purposes. Antibiotics are prescription medications used under a doctor's guidance for specific bacterial infections. Probiotics are a dietary and lifestyle choice many people incorporate — through fermented foods like yogurt, kimchi, and miso, or through supplements — as part of an overall approach to gut health.*
If you're curious whether probiotics might be a good addition to your routine, it's worth looking at labels carefully to understand which strains and doses a product provides, and — as always — checking in with a healthcare provider if you have any underlying health conditions or take other medications.
