Ellagic acid is widely used in the skincare and cosmetics industry due to its antioxidant properties, which help protect the skin from damage caused by free radicals and UV radiation. It is often included in anti-aging creams, serums, and sunscreens to reduce wrinkles, fine lines, and hyperpigmentation. Additionally, its anti-inflammatory effects make it beneficial for soothing irritated or sensitive skin.

In the pharmaceutical sector, ellagic acid is studied for its potential health benefits, including its role in reducing the risk of certain cancers. It has been shown to inhibit the growth of cancer cells and promote apoptosis (cell death) in laboratory studies. It is also being explored for its ability to support cardiovascular health by reducing oxidative stress and inflammation in blood vessels.

Ellagic acid is also used as a dietary supplement, often marketed for its detoxifying and immune-boosting properties. It is found naturally in fruits like pomegranates, berries, and nuts, and is sometimes extracted for use in health products aimed at improving overall wellness.

In the food industry, it serves as a natural preservative due to its antimicrobial properties, helping to extend the shelf life of various products. Its presence in certain foods also contributes to their nutritional value, as it is associated with promoting gut health and reducing inflammation in the digestive system.
