2. Use:

Galactaric acid is commonly used in cosmetics for its ability to improve the skin's texture and appearance. It is known for its exfoliating properties, helping to remove dead skin cells and promote cell turnover. Additionally, galactaric acid has been found to help brighten the skin and reduce the appearance of dark spots and hyperpigmentation.

3. Usage Galactaric Acid:

Galactaric acid is typically found in skincare products such as exfoliating scrubs, serums, and creams. It is recommended to use products containing galactaric acid as directed by the manufacturer, as overuse can lead to skin irritation and sensitivity. It is important to perform a patch test before using products with galactaric acid to ensure compatibility with your skin.
