Yeast Extract
Ingredient Info
Yeast extract is a nutrient-rich ingredient derived from brewer's yeast that contains proteins, amino acids, nucleotides, and trace elements. In skincare, it's used to support skin repair and resilience, with potential benefits for anti-aging and wound healing.
Benefits
- May support collagen synthesis and skin firmness
- Provides antioxidant protection against oxidative stress
- Could improve skin barrier function and wound healing
- May help reduce inflammation and melanin production
Potential concerns
- May cause sensitivity or irritation in individuals allergic to yeast or fermented ingredients
- Limited human clinical trial data; most evidence comes from cell studies
Science: Research shows yeast extract is rich in bioactive compounds including nucleotides that enhance fibroblast activity (skin cell repair), and demonstrates antioxidant and anti-inflammatory properties in cell models. However, most published studies focus on yeast-derived extracts in food or enhanced formulations rather than direct topical skincare efficacy in human subjects.
