1. A method of treating acne vulgaris, comprising administering a surfactant free foam composition dispensed from a container, wherein the container comprises:

  • i) a carrier comprising;

    a) about 60% to about 95% by weight of the carrier of a hydrophobic solvent, wherein the hydrophobic solvent is an oil;

    b) about 0.1% to about 20% by weight of the carrier of at least one fatty alcohol,wherein the fatty alcohol has a carbon chain length of 14 to 22 carbons;

    c) about 0.1% to about 20% by weight of the carrier of at least one fatty acid, at least one wax, at least one shea butter, or mixtures of two or more thereof, wherein the fatty acid has a carbon chain length of 12 to 28 carbons, and the wax is selected from the group consisting of a beeswax, a hydrogenated castor oil, a paraffin wax, a wax that is solid at room temperature, and a mixture of any two or more thereof; and

    d) a minocycline antibiotic; and

    ii) a liquefied or compressed gas propellant;

    wherein the composition comprises 15% or less of petrolatum by weight of the carrier;
