Abstract:
A method for preparing and using a therapeutic antimycotic composition capable of treating acne scars, stretch marks, scars and dark spots, the method comprising the steps of:a) providing a retinoic acid with an excess amount of propylene glycol in a glyco-alcohol solution;b) generating an esterification reaction sufficient to produce a composition, the reaction occurring between the retinoic acid and the propylene glycol so that substantially all of the retinoic acid is esterified and the esterification reaction is conducted in the presence of about 1.35% to about 23.9% by weight of a hydroquinone dissolved in the glyco-alcohol solution, the esterification reaction being accelerated by at least one of a catalyst or heating of the reaction mixture;c) obtaining the composition following esterification without removal of surplus reactants or reactant products; andd) topically applying the obtained composition to the skin in an effective amount sufficient to cause a peeling and antimycotic effect to the skin and a reduction of one or more of acne scars, stretch marks, scars and dark spots on the skin.
