I prefer to use natural colorants for their beauty benefits. Here are a couple that I believe in using, especially for more mature skin types. Get to know your clays! They're fabulous for many uses.
Purple Brazilian clay is a great option for people who want to help prevent aging skin. It’s chock full of magnesium, which promotes healthy cell maintenance — an essential part of maintaining a youthful appearance. Also, purple Brazilian clay helps prevent your skin from absorbing impurities, which is why it’s often used in soap and facial cleansers.
Red Brazillian clay, Red Brazilian clay has a stronger drawing (or absorption) power than other Brazilian clays. This

makes it ideal for people with more oily skin or skin that’s prone to acne. The clay is rich in copper and iron oxide, and has lower levels of aluminum. Because of this, clay masks made using red Brazilian clay are ideal for treating painful or swollen joints. Additionally, red clay helps improve elasticity and promotes a natural lifting effect on your skin.
Brazillian vs kaolin and bentonite clays, With so many different types of clay to choose from, it’s easy to getconfused. Fortunately, once you know the difference between Brazilian, bentonite, and kaolin clays, it’s a lot easier to choose the right product for your skin.

Kaolin clays are fine-grained clays with mild absorbing properties, which makes them ideal for people with dry to normal skin. Brazilian clay is a type of kaolin clay that comes from Brazil. These clays come in a variety of different colors, including red, purple, black, and gold. The clay is naturally colored — they don’t contain artificial dyes or pigments. Instead, the color comes from the minerals that the clay has absorbed over time. Because Brazilian clay is available in a variety of natural colors, it’s often used to add color to homemade soap, skincare products, and cosmetics.

Bentonite clay is clay that’s made from volcanic ash. It’s known for its high absorbing properties. In fact, it can absorb more than its weight in water, which makes it ideal for people with extremely oily skin. High-quality bentonite clay is a greenish-grey color, and the majority of the clay is harvested in the U.S., France, and Italy.

Kaolin Clay's are among the most gentle clays. Mild absorption properties, less drying of the skin. Providing a silky lather in each bar. Clay's are amazing, healthy, and highly beneficial.  :)
