Plant extracts are natural derivatives obtained from various parts of plants, such as leaves, roots, flowers or fruits, and are widely used in cosmetics and food. In cosmetics, they provide antioxidant, moisturising and regenerating properties, making them ideal for products that seek to improve the health of skin and hair. Extracts such as aloe vera, green tea or chamomile are common in creams, tonics and shampoos for their soothing and revitalising effects. In food, plant extracts are used as natural flavourings, colourings and preservatives. Ingredients such as vanilla extract, rosemary or turmeric not only provide flavour, but also nutritional benefits. These extracts offer a natural and healthy alternative and are highly appreciated for their versatility in both the cosmetics and food industries.
