Yeast is a type of fungus that is commonly found in nature, and some strains are known for their potential benefits for skin health.
Skin-Friendly Yeast: Saccharomyces Cerevisiae
One particular strain of yeast, Saccharomyces cerevisiae, has gained attention for its potential benefits for skin. This yeast is often used in skincare products due to its ability to:
- Boost skin hydration: Saccharomyces cerevisiae can help to increase skin moisture levels by promoting the production of natural moisturizing factors (NMFs).
- Reduce inflammation: This yeast strain exhibits anti-inflammatory properties that can help soothe irritated skin and reduce redness.
- Protect against environmental damage: Saccharomyces cerevisiae can help protect the skin from damage caused by environmental factors like pollution and UV radiation.
- Promote skin barrier function: This yeast can help strengthen the skin's natural barrier, which helps protect against moisture loss and irritants.
How Yeast is Used in Skincare
Saccharomyces cerevisiae is often used in skincare products in the form of extracts or fermentates. These ingredients can be found in various products, including:
- Moisturizers: To improve hydration and soothe dry skin.
- Serums: To target specific skin concerns, such as inflammation or uneven skin tone.
- Masks: To provide a boost of hydration and nourishment.
Research and Evidence
While research on the benefits of yeast for skin is ongoing, studies have shown promising results. For example, some studies have found that Saccharomyces cerevisiae extracts can help improve skin hydration, reduce inflammation, and protect against UV damage.
It's important to note that not all yeasts are beneficial for skin. Some strains can be associated with skin infections. Always choose skincare products that use Saccharomyces cerevisiae as a proven ingredient.
