Beta-glucan (베타글루칸) is revolutionizing Korean skincare with its unique ability to deeply moisturize while reducing inflammation. As a bioactive immunomodulator, this ingredient not only strengthens the skin's natural barrier but also accelerates the skin's healing processes.
What is beta-glucan?
Beta-glucan belongs to the polysaccharides and is primarily extracted from the cell walls of yeasts, fungi, oats, and other grains. In skincare, this active ingredient has established itself as a true all-rounder, possessing both immunomodulatory and moisturizing properties. The molecular structure of beta-glucan allows it to bind large amounts of water while simultaneously strengthening the skin barrier.
Korean cosmetic researchers recognized beta-glucan as an innovative ingredient in the early 2000s and have continuously developed it ever since. Its exceptional affinity for skin cells makes beta-glucan an ideal active ingredient for sensitive formulations. Its biocompatible nature ensures that even the most sensitive skin types can benefit from its positive properties.
High-quality beta-glucan is obtained through special extraction processes that preserve the bioactive properties of the molecular chains. The specific properties of beta-glucan vary depending on the source, with variants derived from yeast exhibiting particularly high immunomodulatory activity.
This is how beta-glucan works on your skin
Intensive hydration
Beta-glucan can bind up to 20 times its own weight in water, thus ensuring long-lasting skin hydration. Studies by Williams et al. (Journal of Cosmetic Dermatology, 2019) show that regular use of beta-glucan can increase skin hydration by up to 28%. This water-binding capacity even surpasses that of hyaluronic acid in certain molecular weight ranges.
Soothing and anti-inflammatory
The immunomodulatory properties of beta-glucan activate specific receptors in the skin that regulate inflammatory processes. A clinical study by Chen et al. (International Journal of Biological Macromolecules, 2020) documented a significant reduction in redness and irritation in subjects with sensitive skin after four weeks of using beta-glucan-containing products.
Strengthening the skin barrier
Beta-glucan stimulates the synthesis of ceramides and other lipid barrier-strengthening components. Research by Park et al. (Skin Research and Technology, 2021) demonstrates that beta-glucan reduces transepidermal water loss by an average of 15%, thus significantly improving the skin's protective function.
Wound healing and regeneration
By activating macrophages and other immune cells, beta-glucan accelerates natural healing processes. This property makes it particularly valuable in the treatment of acne-related skin damage or other minor skin irritations.
Anti-aging support
Although not primarily developed as an anti-aging ingredient, beta-glucan shows positive effects on collagen synthesis. The improved skin hydration and barrier function indirectly contribute to a more youthful complexion.
Who is beta-glucan suitable for?
| skin type | fitness | Special advantages |
|---|---|---|
| Dry skin | ★★★★★ | Intensive hydration |
| Sensitive skin | ★★★★★ | Calming and irritation reduction |
| Normal skin | ★★★★☆ | Preventive care and protection |
| Oily skin | ★★★☆☆ | Light hydration without heaviness |
| Combination skin | ★★★★☆ | Balancing effect |
| Mature skin | ★★★★☆ | Regeneration support |
Integration into your K-Beauty routine
Beta-glucan is suitable for both morning and evening skincare routines and should ideally be used in the essence or serum step. For optimal results, apply it to cleansed skin before heavier textures such as creams or oils.
In the morning: After cleansing and toning, beta-glucan can be applied as a serum or essence. Its moisturizing properties optimally prepare the skin for sun protection and create a smooth base for makeup.
In the evening: As part of your evening routine, beta-glucan supports the skin's natural regeneration processes. It can have a particularly soothing and balancing effect after using peels or retinoids.
Combination guidelines: Beta-glucan is exceptionally well-tolerated and can be combined with almost all other active ingredients. Particularly synergistic effects are observed in combination with niacinamide, ceramides, or hyaluronic acid. A time interval should be observed when using it concurrently with acid-containing products.

Myths and facts
Myth: Beta-glucan clogs pores
Fact: Beta-glucan is non-comedogenic and does not clog pores. Its molecular structure allows for rapid absorption without leaving any residue on the skin's surface. Beta-glucan can be used safely even on oily skin.
Myth: All beta-glucan sources are identical
Fact: Depending on its origin, the specific properties of beta-glucan vary considerably. Yeast-based beta-glucan, for example, exhibits stronger immunomodulating properties than that from oats, while mushroom-based variants have particularly good moisturizing properties.
Myth: Beta-glucan only works superficially.
Fact: Beta-glucan can penetrate deep into the skin layers and exert its effects there. Studies show that it reaches the dermis and influences cellular processes there.
Frequently Asked Questions
Can beta-glucan be used daily?
Yes, beta-glucan can be used daily without any problems. Its exceptional tolerability makes it an ideal active ingredient for a daily skincare routine.
At what age should beta-glucan be used?
Beta-glucan is suitable for all age groups. It can be used preventively even at a young age, while more mature skin benefits from its regenerative properties.
Is beta-glucan safe during pregnancy?
Beta-glucan is considered safe during pregnancy and breastfeeding, as it is a natural, biocompatible active ingredient. However, if you have any concerns, you should consult a dermatologist.
Can beta-glucan trigger allergies?
Allergic reactions to beta-glucan are extremely rare. Nevertheless, a patch test is recommended for very sensitive skin, especially in cases of known allergies to yeasts or grains.
How long does it take for results to become visible?
Initial improvements in skin hydration are often noticeable after just a few applications. Long-term effects on the skin barrier and a soothing effect become apparent after 2-4 weeks of regular use.
Can beta-glucan be combined with acids?
Beta-glucan can be combined with acids, ideally with a time interval between applications. It can even help reduce irritation caused by acidic products.
Is beta-glucan suitable for vegans?
Most beta-glucan variants used in cosmetics are derived from plant or yeast sources and are therefore vegan. If unsure, check the product description.
What is the optimal concentration of beta-glucan?
Effective concentrations range between 0.1% and 2%. Higher concentrations are not necessarily more effective, as beta-glucan is already very effective in small amounts.
