A turmeric bar is a type of soap or beauty product that contains turmeric as one of its main ingredients. Turmeric is known for its anti-inflammatory and antioxidant properties, which can benefit the skin. Some turmeric bars may also contain other natural ingredients such as honey, coconut oil, or almond oil, which can also provide additional benefits for the skin. They are used for various skin conditions and to improve skin health, like acne, eczema, and rosacea. It is always recommended to patch test before using these products if you have sensitive skin as some people may have an allergic reaction.
