What are ferments

What Are Ferments?

Fermentation is a metabolic process where microorganisms such as bacteria, yeast, and fungi break down complex organic compounds, such as carbohydrates, into simpler substances like acids, gases, and alcohol. In skincare, fermentation often enhances the bioavailability of ingredients, making them more potent and easily absorbed by the skin. Through this process, the size of molecules is reduced, allowing active ingredients to penetrate deeper into the skin.

Benefits of Fermentation

The use of ferments in skincare is inspired by traditional methods, but modern science has taken it to new heights by isolating specific strains of microorganisms to yield targeted skincare benefits. There is not a lot of convincing research yet, but these are the purported benefits of using fermented ingredients in skincare.

Enhanced Absorption

Fermentation breaks down larger molecules into smaller, more easily absorbed particles, increasing the potency of active ingredients such as vitamins, amino acids, and antioxidants.

Increased Efficacy

Fermented ingredients can increase the concentration of active compounds, such as peptides and enzymes, enhancing the effectiveness of products.

Microbiome Balance

Some fermented ingredients, like probiotics, can help balance the skin's microbiome, supporting the growth of beneficial bacteria while minimizing harmful bacteria.

Side-effects of ferments

Side Effects and Downsides

While ferments offer many benefits, they are not without potential side effects. Fermented ingredients may cause irritation in sensitive skin types, especially if the fermentation process increases the acidity of the product. Additionally, there is limited data on the long-term efficacy of fermented ingredients. 

Types of Ferments

There are many types of ferments. This article will focus on the most popular ferments used in skin care products today.

Its ability to protect against environmental stressors like UV damage and pollution further enhances its role in skincare formulations.

Saccharide Isomerase

Produced through the fermentation of Streptococcus pyogenes. Saccharide Isomerase acts as a humectant, deeply hydrating the skin by converting glucose to fructose. It enhances moisture retention, softens skin texture, and repairs the skin barrier. It also reduces irritation and supports anti-aging by promoting skin elasticity and plumpness while fighting free radical damage.

Thermus Thermophillus Ferment

Thermus thermophillus ferment is an antioxidant and anti-inflammatory ingredient derived from a marine bacterium. It reduces inflammation by suppressing NF-κB , a transcription factor that controls pro-inflammatory cytokines like TNF-α and IL-6 , which helps calm and soothe the skin. Additionally, it acts as a humectant , attracting moisture and preventing transepidermal water loss (TEWL) , thereby improving skin hydration. By reducing oxidative stress and inflammation, it supports anti-aging efforts by preventing damage and maintaining skin elasticity. In skincare, it calms irritation, enhances hydration, and has anti-aging effects. It is found in the skin care products shown below.

Vibrio Alginolyticus Ferment Filtrate

Source: This ferment is derived from a marine bacterium found in deep-sea waters. It's often used for its ability to provide rapid hydration and strengthen the skin's barrier.

Benefits: Clinical studies suggest that Vibrio Alginolyticus Ferment Filtrate may increase skin hydration, improve firmness, and promote a lifting effect. One study found a visible reduction in wrinkle depth after 30 minutes of application. It is also known to stimulate sirtuin-3, a protein linked to cellular energy production and longevity, thereby improving the skin’s resilience against oxidative stress.

Where do Ferments Come From?

Ferments are derived from various sources, including bacteria, fungi, and yeast. Marine-derived ferments, in particular, are a growing area of interest in the skincare industry. During the 2010 Malaspina Expedition, scientists collected marine samples from five continents and isolated over 120 previously unknown bacterial strains. These strains are studied for their potential anti-aging and skin-repairing properties. For instance, one bacterium collected near Madagascar was fermented to produce a Bacillus Ferment that has been shown to improve skin texture, increase cellular energy, and reduce the appearance of wrinkles.

Research on Ferments

Research Studies on Ferments

There is a paicity of data on ferments. Most studies are computer generated analysis of the possible mechanisms of action that th eferments might have based on their components and strucure. In most cases, studies of final formulations on human skin have not been done. This is some of what we k now.

Several studies have looked at the effects of Bacillus Lysate on the skin. (3) One study showed that it can upregulate the sirtuin-3 gene, enhancing ATP production and reducing oxidative stress by 4%. Another in vivo study found a 13% reduction in wrinkle depth just 30 minutes after application, highlighting the potential for immediate visible improvements. However, it’s essential to note that while these early results are promising, more extensive clinical trials are needed to fully validate the efficacy of fermented ingredients.

Ferments offer intriguing potential in the world of skincare, but much remains to be learned about their long-term efficacy and safety. With ongoing research and development, we may soon better understand how these biologically active compounds interact with the skin to provide the anti-aging and healing benefits they promise. In the meantime, consumers should approach fermented ingredients with both interest and caution, always keeping their individual skin type and sensitivities in mind.

What do ferments do in skin care?

There are many types of ferments and the benefits depend on their source. Benefits may include antiaging, suppression of inflammation, effects on the microbiome, and moisturization.

What are the benefits of using fermented ingredients in skincare?

Fermented ingredients can enhance the bioavailability of active compounds, making them easier to absorb by the skin. This process often increases the potency of vitamins, amino acids, and antioxidants, providing better hydration, anti-aging effects, and skin barrier support. Fermentation also helps break down large molecules, improving ingredient penetration.

Are fermented skincare products safe for sensitive skin?

While many fermented ingredients can be soothing and hydrating, individuals with sensitive or reactive skin should be cautious. Some users report irritation, especially when using products containing multiple ferments or acids. It’s best to patch test and introduce fermented products gradually into your routine.

Can fermented ingredients cause fungal acne?

There's some concern that fermented ingredients, especially those with yeast or sugar, might exacerbate fungal acne. This is because certain fermented substances may theoretically feed yeast. However, this risk varies by individual and the type of ferment used.  If you have acne that does not clear with the usual therapies, discuss with your dermatologist. They can do a culture to see if a fungus or yeast is the culprit.

How do First Treatment Essences (FTEs) work?

FTEs are watery, fermented skincare products designed to be the first step after cleansing. They are often packed with ferments like Galactomyces or Saccharomyces, which can soften, brighten, and hydrate the skin. Users typically apply FTEs to prep the skin for better absorption of subsequent products. They work the same way as the ferments discussed in this article.

Are ferments better than non-fermented ingredients?

It depends. Fermentation can enhance the efficacy of some ingredients by breaking them down into more active or potent forms. However, not all ingredients benefit from fermentation, and in some cases, fermentation may reduce their effectiveness. It’s important to evaluate the specific product and match it to your Baumann Skin Type.
