01
What is Bentonite?
Bentonite is a type of clay formed from volcanic ash, known for its exceptional absorbent and adsorbent properties, proving its worth for centuries. These properties mean that bentonite is especially suited for drawing out contaminants and binding to them. Bentonite is also rich in minerals like calcium, magnesium, and iron, which can be helpful for medicinal and skin care purposes.Importantly, there are two primary types of bentonite clay: sodium bentonite and calcium bentonite. Sodium bentonite swells when it comes into contact with water, which increases its volume by up to a factor of eight and is often used in industrial applications, such as sealing ponds and landfills. Calcium bentonite, on the other hand, does not expand to the same degree and is sometimes preferred for skin care due to its higher calcium content and gentler nature.

What Does Bentonite Do for Skin?
Bentonite clay is used in skin care for its ability to draw impurities and excess oil from the skin's surface, acting as a natural purifier. This is possible since the clay innately possesses an overall negative charge due to the sodium and calcium ions present.1 It’s this property that attracts positively charged toxins and particles, thereby making it an effective detoxifying agent. The cation-ion interactions between toxins and the clay particles lend to its antibacterial activity and provide essential minerals to the body. 2 Thus when applied topically, bentonite clay can help unclog pores, reduce acne breakouts, and soothe irritation, leaving the skin feeling refreshed and rejuvenated.3
