This article was last updated on: October 19, 2023

Cosmetics can sometimes be a tad confusing, particularly when we delve into the ingredient lists. These are often packed with complex scientific names that would feel more at home in a biotech lab than on your bathroom shelf.

One ingredient you may have stumbled across in your skincare products is the scientific-sounding Saccharomyces/Rice Ferment Filtrate. Quite a mouthful, isn’t it? It’s like being back in high school biology class all over again!

This article will navigate the labyrinth of this intriguing compound, demystifying exactly what it is, and explaining why it has found its place in our cosmetic products. We’ll peel back the layers of Saccharomyces/Rice Ferment Filtrate, analyzing its benefits and potential side effects for the skin too!

What is Saccharomyces/Rice Ferment Filtrate?

Saccharomyces/Rice Ferment Filtrate, also known as fermented rice water, Pitera, or rice yeast, is a skincare ingredient derived from the fermentation of Oryza sativa (rice) by a specific microorganism known as Saccharomyces.

In simpler terms, it’s a by-product of yeast fermenting rice. This bioactive ferment is known for its skin conditioning properties and is commonly used in the formulation of various skincare products, from serums and moisturizers to toners and masks.

Its primary role is to condition the skin by strengthening the skin barrier and maintaining its natural microbiome balance – a well-balanced skin microbiome can better defend against environmental factors and retain moisture, contributing to healthier-looking skin.

While Saccharomyces/Rice Ferment Filtrate can be found in standalone formulations, it’s most commonly incorporated into a broader blend of ingredients to amplify its benefits. Concentration may vary depending on the product, but it often falls within the 0.5% to 5% range.

Who Can Use Saccharomyces/Rice Ferment Filtrate?

Saccharomyces/Rice Ferment Filtrate is a versatile skincare ingredient that is suitable for all skin types. Whether you have oily, dry, combination, or sensitive skin, this skin conditioner can work wonders.

Vegans and vegetarians can also rejoice. Saccharomyces/Rice Ferment Filtrate is plant-derived, making it entirely animal-free and suitable for those following a vegan or vegetarian lifestyle.

In terms of its use during pregnancy or breastfeeding, there aren’t any known concerns. However, as with introducing any new product during these critical stages, it’s always safest to consult your healthcare provider before including Saccharomyces/Rice Ferment Filtrate in your skincare regime.

Saccharomyces/Rice Ferment Filtrate Skin Benefits

Saccharomyces/Rice Ferment Filtrate offers a plethora of skin-enriching benefits, diving beneath the skin’s surface to deliver comprehensive conditioning. Here are some of the key benefits of this wonder ingredient based on its official function as a skin conditioner:

  • Maintains Skin’s Natural Microbiome: Saccharomyces/Rice Ferment Filtrate helps preserve the skin’s natural microbiome balance. It creates a friendly environment for the beneficial bacteria that call our skin home, maintaining their population while keeping the harmful ones in check. A balanced microbiome is pivotal in defending against environmental aggressors, reducing inflammation, and promoting overall skin health.
  • Strengthens Skin Barrier: This ingredient also aids in reinforcing the skin barrier, the outermost layer of our skin. The skin barrier is our first line of defense against external stressors like pollutants and harmful bacteria. Saccharomyces/Rice Ferment Filtrate contributes to the strengthening of this layer, enhancing its ability to defend against these stressors and reducing the likelihood of skin issues such as dryness, irritation, or inflammation.
  • Improves Moisture Retention: Saccharomyces/Rice Ferment Filtrate promotes healthier, more hydrated skin by improving the skin’s ability to retain moisture. It does this by enhancing the function of the skin barrier, preventing the evaporation of the skin’s natural moisture (a process known as Transepidermal Water Loss), and contributing to plumper, smoother, and more hydrated skin.

It’s important to note, though, that the benefits of Saccharomyces/Rice Ferment Filtrate are not permanent. Your skin is a living organ constantly renewing itself, and so, continued usage of products containing this ingredient is essential to sustain these beneficial effects and keep your skin looking its best.

Saccharomyces/Rice Ferment Filtrate Potential Side Effects

Just like our personalities, our skin is unique to us, and so are its reactions to different cosmetic ingredients. Our skin’s responses are influenced by various factors, including our skin type, overall health, age, and the presence of any skin conditions.

Considering that, let’s delve into possible side effects and potential interactions linked with Saccharomyces/Rice Ferment Filtrate:

  • Irritation: While uncommon, some individuals might experience irritation when using Saccharomyces/Rice Ferment Filtrate products. This might manifest as redness, itching, or a burning sensation.
  • Allergic Reaction: In rare instances, a user may have an allergic reaction, identifiable by symptoms such as hives, swelling, or difficulty breathing. If you experience this, seek immediate medical attention.

If you were to experience any of these side effects while using a product containing this ingredient, discontinue its use immediately and consult with a dermatologist or other healthcare professional. They can provide advice tailored to your specific situation.

However, it’s important to note that adverse reactions to Saccharomyces/Rice Ferment Filtrate are rare. More often than not, this ingredient is safe and effective, delivering comprehensive skin conditioning benefits.

Even with this in mind, it’s always wise to carry out a patch test before incorporating a new product into your routine – even those deemed generally safe. Patch testing can help you identify any potential adverse reactions in a controlled manner, preventing widespread discomfort or damage to your skin. For a step-by-step guide on how to do this, you can refer to our comprehensive patch-testing guide.

Comedogenic Rating

On the comedogenic scale, Saccharomyces/Rice Ferment Filtrate is rated as 0/5, suggesting it’s non-comedogenic.

This rating is attributed to its unique fermentation process, which breaks down complex molecules into smaller, easily absorbed compounds that are less likely to clog pores. Therefore, Saccharomyces/Rice Ferment Filtrate is suitable for individuals prone to acne or breakouts, as it does not contribute to pore-clogging, a primary cause of acne.


Achieving skin health and beauty is a journey paved with experimentation and trial-and-error. Skincare is not a one-size-fits-all, and different ingredients work differently for everyone. Consistency becomes your best ally once you identify what works for your skin.

Saccharomyces/Rice Ferment Filtrate stands out for its multifaceted benefits. Its ability to balance the skin’s microbiome, strengthen the skin barrier, and improve moisture retention makes it a noteworthy addition to any skincare routine.

While it’s not as instantly recognizable as ingredients like hyaluronic acid or retinol, Saccharomyces/Rice Ferment Filtrate is steadily gaining traction and popularity in the skincare industry. It bears similarities to ingredients like fermented soy and bifida ferment lysate, which are also derived through fermentation, sharing benefits like improved skin resilience and moisture retention.

The timeline to witness noticeable results from Saccharomyces/Rice Ferment Filtrate can vary. However, with consistent use, most individuals may start to see improvements in their skin texture and hydration levels within a few weeks.

Given its uncommon-sounding name, you may have concerns about Saccharomyces/Rice Ferment Filtrate. Rest assured, while it may sound like a high-tech, synthetic ingredient, it’s quite the opposite. Derived from natural fermentation, it’s a skin-friendly component with minimal side effects. Remember, skincare is personal, and what matters most is finding what works for your unique skin.
