Can Yeast Beta-Glucan Be Used in Skincare? Understanding Its Applications in Skin Care
In the realm of skincare ingredients, beta-glucan is a familiar name. Oats, mushrooms, and yeast are all natural sources of beta-glucan; however, beta-glucans derived from these different sources vary in terms of molecular structure, physicochemical properties, and biological activity.
Among these, yeast beta-glucan has garnered attention within the cosmetic ingredient industry for its potential in maintaining the skin barrier, soothing the skin, and facilitating skin repair. Can yeast beta-glucan truly be used for skincare? What benefits does it offer the skin, and for which types of skincare products is it best suited?
I. What Is Yeast Beta-Glucan?
Yeast beta-glucan is a natural polysaccharide primarily found in the cell walls of yeast. It is typically obtained through processes such as extraction, isolation, and purification.
In terms of molecular structure, yeast beta-glucan consists of a main chain linked by β-(1,3)-glycosidic bonds, with side chains formed via β-(1,6)-glycosidic bonds. This branched polysaccharide structure differs from that of oat-derived beta-glucan, which is primarily composed of β-(1,3)/(1,4)-glycosidic bonds.
Beta-glucans from different sources cannot be treated as the same ingredient. They may vary in molecular weight, degree of branching, solubility, and biological activity; therefore, when developing cosmetic formulations, it is essential to select the appropriate type of beta-glucan based on the specific application.
A key reason for the interest in yeast beta-glucan is its interaction with receptors involved in the skin's immune recognition. Research in this area has focused on how it influences skin cell responses, inflammatory signaling, and tissue repair processes.
II. What Are the Benefits of Yeast Beta-Glucan for the Skin?
The value of yeast beta-glucan in skincare extends beyond simple moisturization. Research has primarily focused on its role in maintaining the skin barrier, soothing the skin, providing antioxidant protection, and supporting skin repair.
1. Maintaining Skin Barrier Function
The skin barrier is a vital foundation for maintaining healthy skin, composed primarily of keratinocytes, intercellular lipids, and natural moisturizing factors (NMFs). When the skin barrier is compromised by external irritants or environmental changes, issues such as dryness, tightness, and roughness can arise.
Research indicates that yeast β-glucan may influence the expression of proteins associated with the skin barrier, including:
- **Filaggrin (FLG):** Involved in the maturation of keratinocytes and the formation of natural moisturizing factors, it helps maintain the water-retention capacity of the stratum corneum.
- **Loricrin (LOR):** A key structural protein of the cornified envelope, which plays an essential role in preserving the structural integrity of the stratum corneum.
In specific cell-based experiments, treatment with 10 mg/mL of yeast β-glucan resulted in an increase in the expression levels of FLG and LOR to 2.18 times and 11.2 times those of the control group, respectively.
These findings suggest that yeast β-glucan has the potential to contribute to the maintenance of the skin barrier, providing a basis for its application in skincare products designed for barrier support.
2. Soothing the Skin and Improving Sensitivity
Changes in the external environment, exposure to ultraviolet (UV) radiation, and other irritants can trigger skin discomfort, manifesting as redness, stinging, or dryness.
The interaction between yeast β-glucan and immune-related receptors in the skin is a key area of research into its soothing properties. Some studies suggest that it may modulate signaling pathways—such as NF-κB and MAPK—to influence the expression of inflammation-related factors, thereby helping to alleviate the inflammatory response following skin irritation.
In a human clinical test, the application of a lotion containing 0.3% yeast β-glucan led to an improvement in skin redness. After 14 consecutive days of use, the area affected by redness was reduced by approximately 27.41%. Therefore, yeast β-glucan serves as a promising candidate ingredient for soothing skincare formulations, making it well-suited for products designed to address skin discomfort or provide daily calming care.
3. Antioxidant properties: Helping to combat environmental stress
Ultraviolet (UV) radiation, air pollution, and other environmental factors can trigger the production of reactive oxygen species (ROS) in the skin. Persistent oxidative stress can impair the normal function of skin cells and contribute to the skin aging process.
Research indicates that yeast β-glucan exhibits antioxidant potential and the ability to modulate inflammatory responses in cellular studies. It can influence the generation of ROS in keratinocytes exposed to UV radiation and regulate specific signaling pathways associated with inflammation.
This makes it a valuable component for daily protective skincare products, particularly when combined with moisturizers, other antioxidants, and soothing agents.
It should be noted that yeast β-glucan is not a substitute for sunscreen and cannot, on its own, provide comprehensive protection against UV-induced damage.
4. Addressing fine lines and dryness
Skin repair involves a complex series of biological processes, including cell proliferation, the formation of the extracellular matrix, collagen synthesis, and the reconstruction of tissue structure.
The interaction between yeast β-glucan and specific immune cell receptors has made it a subject of interest in skin repair research. Some studies have also explored its impact on fibroblast activity and processes related to collagen production.
In a human clinical study, the application of an emulsion containing 0.3% yeast β-glucan over 28 consecutive days resulted in a reduction of approximately 13.27% in the surface area of fine lines around the eyes, a 52.78% increase in stratum corneum hydration, and a 15.29% decrease in transepidermal water loss (TEWL).
These findings suggest that, beyond its role in skin soothing and barrier support, yeast β-glucan may also be a beneficial ingredient for products targeting fine lines by improving skin hydration and overall appearance. It is important to distinguish between daily skin repair in the context of cosmetics and the medical treatment of wounds; experimental results in the former cannot be directly equated to clinical therapeutic outcomes.
III. In which types of skincare products can yeast β-glucan be used?
As consumers increasingly focus on gentle care, the maintenance of the skin barrier, and multifunctional skincare formulations, the range of applications for yeast β-glucan continues to expand.
1. Repair Serums and Creams
Yeast β-glucan can be incorporated into formulations designed for skin barrier maintenance, hydration, and soothing. It pairs well with ingredients such as ceramides, hyaluronic acid, and panthenol to create a multidimensional approach to barrier care.
2. Products for Sensitive Skin
It can serve as a complementary ingredient in soothing formulations. When combined with components like *Centella asiatica* extract, other compatible forms of β-glucan, or glycyrrhizinate, it meets the development requirements for daily skincare products tailored to sensitive skin.
3. Antioxidant and Daily Protective Products
It can be paired with vitamin E, plant polyphenols, and other antioxidants for use in facial serums, lotions, and daily skincare creams.
4. Eye Care Products
Given its proven benefits in hydration and skin condition improvement, yeast β-glucan can be used in the development of eye creams and eye serums, addressing concerns such as dryness and fine lines around the eye area.
5. Body Care and Specialized Skincare Products
Beyond facial skincare, yeast β-glucan also holds potential for use in body lotions, hand creams, and other skin care products. Specific applications should be evaluated based on raw material specifications, product positioning, and regulatory requirements.
Conclusion
As the cosmetics industry’s demand for multifunctional active ingredients and scientifically-backed formulations grows, yeast β-glucan is poised to see broader application in products such as repair serums, barrier-supporting creams, sensitive skin care, and eye care.
