Loess Extract

1. Definition Loess Extract:

Loess extract is a natural ingredient derived from fine-grained sedimentary rock that is rich in minerals such as silica, magnesium, calcium, and potassium. It is known for its detoxifying, purifying, and soothing properties, making it a popular ingredient in skincare products.

2. Use:

Loess extract is commonly used in cosmetics for its ability to absorb excess oil, unclog pores, and improve skin texture. It is often found in masks, cleansers, and exfoliators to help purify the skin and promote a clearer complexion. Additionally, the mineral-rich properties of loess extract can help nourish and hydrate the skin, leaving it looking revitalized and refreshed.

3. Usage Loess Extract:

When using skincare products containing loess extract, it is important to follow the instructions provided by the manufacturer. As with any new ingredient, it is recommended to perform a patch test before applying it to the entire face to check for any potential allergic reactions. It is also advisable to start with a small amount of product and gradually increase usage to avoid overstimulating the skin.
