Carnosol is widely used in the food industry as a natural antioxidant to preserve the freshness and extend the shelf life of various products, particularly meat and oils. It helps prevent oxidation, which can lead to spoilage and rancidity. In the pharmaceutical and cosmetic industries, carnosol is valued for its anti-inflammatory and antimicrobial properties, making it a key ingredient in skincare products aimed at reducing acne, redness, and signs of aging. Additionally, it is studied for its potential therapeutic benefits in managing chronic diseases, such as cancer and neurodegenerative disorders, due to its ability to combat oxidative stress and inflammation. Its application in dietary supplements also supports overall health and wellness.
