In previous years, the conversation seemed to focus on the deeper, collagen-producing layers of the skin.
Now, the attention is on the very surface layer and its microorganisms and bacteria.

These microbes are essential to your skins flora and, in short, keep it functioning as it should.
When your microbiome is compromised, issues in the form of inflammation tend to take shape.
However, the question remains: How effective are probiotics and prebiotics for your skin?
We spoke to a trio of skincare pros to find out once and for all.

Probiotics in Skincare
So, what are probiotics?
“Probiotics are living organisms that benefit the health of their host,” says Hickman.
“These good bacteria have been shown to strengthen the immune system and improve nutrition absorption.”
When used in your skincare, probiotics balance and improve your skin’s microbiome.
“These lysates or fermented extracts are actually closer to postbiotics.”
According to Dr. Mikaliov, lysates contain molecules broken down by probiotics in their living state.
Common ingredients are oat, rice, flaxseed, soy, glucomannan, and ginseng.
These elements serve as nutrition for the ‘good’ bacteria to keep your skin’s microbiome healthy.
For example, are the prebiotics in a cleanser for oily skin or a moisturizer for dry skin?"
Additionally, because prebiotics aren’t living ingredients, Dr. Jungman notes that they tend to be more shelf-stable.
It is worth noting the two ingredientscanbe combined into a single formula, known as a symbiotic product.
However, Dr. Jungman notes that the jury is still out on whether the combination is more efficacious.
Topical vs.
According to Dr. Mikaliov, they’re better used to balance and nourish your gut flora.
“Oral prebiotics include a lot of fiber-rich food that help balance your gut microbiome.”
Hickman echoes his sentiment.
“Topical applications are always more impactful for treating the skin directly.”
Hickman advises thinking about the function of the product you want to add and the ingredients it contains.
Additionally, take a closer look at the ingredients in the formulas you’re currently using.
Probiotics and prebiotics are so common in skincare, so they may already be in your rotation.
“For example, oat extract is a prebiotic readily used in skincare formulas.”
Prebiotics, in general, are more stable and easier to incorporate into a product.
