Claims15
In a hair removal system, the combination comprising:
- iontophoretic means for delivering a chemical depilatory agent into the skin of a biological subject at a site where hair to be removed is located;
- and
- a non-enzyme chemical depilatory agent and a skin permeability enhancing agent for delivery into the skin by said iontophoretic means whereby long term or permanent hair removal is facilitated.
A method for long term or permanent hair removal, comprising the steps of:
- locating the site of hair to be removed from a biological subject;
- and
- iontophoretically delivering a non-enzyme chemical depilatory agent and a salicylate into said site and sufficiently deep to substantially damage hair papilla, whereby long term hair removal is accomplished without physical injury to the subject.
For use with an iontophoretic delivery system to remove hair, an electrode and an agent supporting member comprising:
- an electrode and an agent support member;
- and
- a non-enzyme chemical depilatory and a salicylate supported by said member for iontophoretic delivery.
