Benefits of Prebiotic & Probiotic Skin Care

Benefits of Prebiotic & Probiotic Skin Care

Ingesting probiotics for a healthy gut isn’t news, but the topical application of probiotics for healthy skin is. So, how does prebiotic and probiotic skin care work?

When we implement probiotics, or healthy bacteria, and prebiotics, which feed healthy bacteria, into our skin care routine, it supports the healthy function of our skin barrier. Our skin barrier, albeit powerful, is sensitive and can easily be disrupted by, well, almost everything. Environmental pollution, allergens, dirt, bacteria, moisture (or lack thereof) in the air, rays from the sun, and more all affect how our skin barrier functions. Probiotics and prebiotics, though, affect how our skin barrier functions in a good way.

Researchers have only scraped the surface of their many benefits for the skin, but we’ve heard enough to know probiotic and prebiotic ingredients can be incredibly beneficial. Read on to learn more about the best probiotic skin care and how it can impact your skin for the better.

What is Probiotic Skin Care?

You’ve heard the hype, but what actually is probiotic skin care?

Probiotics Are...

Probiotics are good, beneficial bacteria and yeast that exist in the body but also are typically found in yogurt and oral supplements. They support the healthy bacteria found in the gut, which can aid digestion and ward off a slew of gut-related issues, including...wait for it… skin problems. Oral probiotics benefit the skin, but topical probiotics should have a place on your shelf too.

Similar to how probiotics promote a healthy balance of bacteria in the gut, they can promote a healthy balance of bacteria on the skin. When the skin microbiome (where the bacteria lives) is in balance, it helps better regulate the skin barrier, which affects how the skin manages breakouts, irritation, and other aggravators. Read our blog called “How do Probiotics Work” for more details.

TL;DR: Healthy balance of bacteria, healthy-looking skin. And the topical application of probiotics can help support a healthy balance of bacteria.

Probiotic Skin Care Ingredients

Now, when we talk about topical probiotic skin care, it’s important to note that there isn’t “living” bacteria in most probiotic skin care products, as no bacteria would survive in the midst of preserving ingredients. There are non-living strains of probiotic bacteria, though, as well as microbiome supporting ingredients (prebiotics and postbiotics). These are the types of ingredients found in “probiotic skin care”. And this is a good thing! It means your products still boast the benefits of living bacteria but will work for you longer.

When you survey the labels of skin care products, you won’t always find “probiotics” listed. So, you’ll need to look for the scientific ingredient. This can get a little tricky, so we’ve listed some of the key players out for you here.

Probiotic ingredients commonly found in skincare:

Lactobacillus, Bifidobacterium, and Vitreoscilla and variations
Lactococcus ferment lysate, Bifida ferment lysate, and other ferments and lysates
What is Prebiotic Skin Care?
What, then, is prebiotic skin care, and how is it different from probiotic skin care? We’re so glad you asked…

Prebiotics Are...

Prebiotics are a type of fiber that good bacteria feed on. The microbiome of your skin is made up of living organisms that require prebiotics in order to stay balanced. In this way, prebiotics support the skin’s microbiome by feeding it the ingredients it needs to produce probiotics that keep it balanced and healthy.

Prebiotic skin care is slightly different from probiotic skin care in the fact that instead of containing actual probiotic ingredients, the ingredients support a healthy balance.

Prebiotic Skin Care Ingredients

Similar to probiotic skin care ingredients, you won’t find “prebiotics” on the ingredient label. Instead, you may see something that looks like these:

The Benefits of Probiotic & Prebiotic Skin Care

When it comes to probiotic skin care and prebiotic skin care, it’s not a question of which one. Both probiotics and prebiotics offer benefits that support the skin, and when used in tandem, work even more effectively. These are the main benefits of probiotic and prebiotic skin care, which apply to everyone:

Helps Strengthen the Skin’s Natural Barrier

The skin microbiome, remember this is where the good bacteria live, is a key component of the skin’s barrier function. Probiotics support the healthy balance of bacteria in the skin microbiome, which strengthens the skin barrier, encouraging its shielding ability. When the skin barrier is strong, the skin is protected from environmental stressors such as UV damage, environmental pollution. Another important role of the skin’s barrier is keeping moisture from escaping. By supporting the skin’s natural barrier, probiotics also support hydration. Check out our blog on How to Protect Your Skin Barrier to learn more.

Calms Skin

Probiotics have soothing benefits for the skin as well. Whether you have sensitive skin or your skin is prone to irritation or redness, probiotics are not only gentle enough to use but also beneficial. They can not only have a quick calming effect but also decrease skin sensitivity and increase resistance to aggravators in addition to strengthening the skin’s barrier to shield against them.

Help Manage Blemishes

The skin microbiome has both good and bad bacteria, but when the bad bacteria overrun the good, you may get blemishes. When it comes to blemishes, bad bacteria are a major culprit. Probiotics can ensure a healthy bacterial balance and thus help prevent and reduce blemishes.

Promotes Healthy-Looking Skin

The real benefit of strengthening the skin’s natural barrier, helping lock in moisture, calming down the skin, and managing blemishes, thanks to probiotics and prebiotics, is that these actions help to achieve healthy-looking skin. When the skin’s moisture barrier is strong, the skin is less prone to irritation, dehydration, blemishes, developing signs of aging, and more. Further, by supporting the skin’s natural microbiome, probiotics and prebiotics help the skin function as it should.
