Finding a specific paper on the use of fermented extracts in soap and its benefits for the skin can be challenging, but there are several studies that support the general benefits of fermentation in skincare. Here are some relevant studies and findings that back the efficacy of fermented ingredients for skin health:
1. Fermentation Enhances Skin Benefits:
A study titled *Lactic Acid Bacteria Fermentation and Its Application to Skin Care* (2016, *Journal of Applied Microbiology*) discusses how fermented ingredients, such as those from lactic acid bacteria, can strengthen the skin barrier, improve hydration, and enhance the effectiveness of nutrients that benefit the skin. Fermentation increases the bioavailability of certain compounds, making them more beneficial when applied to the skin.
2. Antioxidant and Anti-inflammatory Properties of Fermented Products:
In *The Effects of Fermented Products in Skin Care: A Review* (2019, *Journal of Clinical and Aesthetic Dermatology*), it is highlighted that fermented ingredients possess antioxidant properties that help prevent skin aging, reduce inflammation, and improve skin barrier function. These fermented extracts can soothe skin irritation and provide essential nutrients for skin health.
3. Fermented Fruit Extracts for Skin Care:
The paper *The Role of Fermented Plant Extracts in Skincare* (2020, *Journal of Cosmetic Dermatology*) outlines how fermented fruit extracts improve skin tone, reduce wrinkles, and provide anti-inflammatory effects. The study also notes that enzymes activated during fermentation promote natural healing and regeneration of the skin.
These studies demonstrate that fermented extracts can have beneficial effects on the skin, supporting the idea that soap made with fermented extracts may provide various skin benefits, such as hydration, anti-aging, and soothing properties.
