about 16.5% w/w to about 30.7% w/w of coconut oil;
about 3.5% w/w to about 6.5% w/w of cyclomethicone; and

(b) a propellant in an amount ranging from about 3% to about 25% w/w; and
wherein the foamable composition does not comprises silicon dioxide (SiO2),wherein seven days of topical treatment with the breakable foam at the therapeutically effective amount results in a maximum concentration of minocycline in plasma from the subject of about 2 ng/mL, as measured during a 24 hour period following the last topical administration, andwherein the subject is between 15 years old and 16 years and 11 months old.
