Bentonite clay, often referred to as calcium bentonite clay or montmorillonite clay, is a phyllosilicate clay formed from aged volcanic ash. Known for its negative charge and strong adsorption properties, this natural clay has been used since ancient times for various health benefits. One of the largest sources of natural clay is found in the United States, where it is mined for a wide range of applications, including cosmetic and digestive uses.
Benefits of bentonite clay for the skin
The benefits of bentonite clay in skincare, especially in facial masks, are supported by both animal studies and human studies. It is known to absorb oil from oily skin, remove dead skin cells, and help clear up chronic skin lesions and skin rashes. The clay’s antibacterial properties and antimicrobial properties also make it effective for acne-prone and sensitive skin. Unlike synthetic materials, this natural product contains no artificial colors or harsh materials, making it suitable for those with allergic contact dermatitis or chronic hand dermatitis.
How to make and use a bentonite clay mask
A bentonite mask can be made by mixing bentonite clay powder with water or apple cider vinegar (some refer to it as apple cyder). It’s important not to use metal utensils, as they may affect the clay's electrical charge. Once the powder with water or vinegar is mixed into a smooth paste, apply it to the face and let it dry for 10–15 minutes. Rinse thoroughly with warm water. This deep cleansing facial clay mask can help manage acne breakouts by drawing out toxins and heavy metals from the skin.
Other common uses of bentonite clay
Beyond facial skincare, bentonite clay is used in various household and personal care applications. It serves as a natural hair cleaner or hair cleanser in clay-based hair treatments, and is often found in detox bath products. It’s also used to soothe bug bites, insect bites, diaper rashes, and infantile diaper dermatitis. In natural and organic cleansing products, bentonite clay is combined with ingredients like coconut oil or castor oil to enhance its healing clays effect.
Internal consumption and health concerns
Some people take bentonite clay by mouth in the form of bentonite clay capsules or drink clay with water, especially food-grade bentonite clay. Advocates claim it helps the digestive tract and conditions like irritable bowel syndrome. However, scientific studies suggest that oral bentonite may interfere with nutrient minerals like elemental magnesium and affect mineral metabolism. There have been reports of side effects such as severe hypokalemia, particularly in pediatric patients and pregnant women. Always consult a healthcare provider before internal use.
Understanding product quality and forms
The cosmetic market includes a variety of bentonite clay products such as Indian healing clay, cosmetic grade clay, and food-grade bentonite clay. Look for labels indicating the clay is a clean, organic material. While products like clay from beauty supply stores may be appealing, it’s essential to understand the effects of bentonite clay and the typical forms it comes in—cream color powders, bentonite clay mask pastes, and clay side effects documentation. Consider the 90-day median price, any shipping charges, and ensure that you're purchasing from a reliable source.
