Many of the Aloe Vera products you find on the market today do not use the entire leaf of the plant claiming that it’s of no efficacy. However, the greatest concentration of Aloe Vera's active ingredients is where the rind interfaces with the inner gel of the leaf.

What is the different between Whole Leaf and NON-Whole Leaf Aloe Vera?
In a product that is mostly water, you want the most active ingredient solids as possible. The greatest concentration of Aloe Vera's active ingredients solids is where the rind interfaces with the inner gel of the leaf. When only the inside of the leaf is used the result is a lower potency Aloe Vera product.
