Abstract:
Effective enhancement of eyelash length and density can be obtained by topical applications of an active agent selected from a class of compounds consisting of synthetic prostaglandin agonists, polymers thereof and mixtures thereof preferably having the chemical formula of CHNO, such as 7-[3.5-dihydroxy-2-(3-hydroxy-4phenoxy-but-1-enyl)-cyclopentyl]-hept-5-enoic acid ethylamide. Such active agents having a molecular weight of 417.54 can be employed in concentrations from 0.00075% to 0.03% by weight in mixtures with inactive ingredients, such as gels, oils, etc. Results are obtained by daily topical applications of active agent in such liquid mixtures (tinctures) at the roots of the lashes and/or lash follicles.
