No Structural Compromises: Sticks require a solid, waxy base to hold their shape. Sprays need propellants and solvents. Balms avoid these, allowing for a purer, more concentrated formula with a higher percentage of active ingredients (like moisturizers, clays, and baking soda alternatives).
Wider Ingredient Range: Brands aren't limited to heat-stable, firm waxes. They can use luxurious butters (like shea or cocoa), nourishing oils, and clays that wouldn't work in a stick mechanism.
