Abstract
A device for disrupting hair growth includes an applicator sized and configured to be held in a hand of a user for shaving, and a source of electromagnetic energy constructed to emit electromagnetic energy having an energy density of between about 0.1 J/cm2 and about 15 J/cm2 and, more preferably, between about 0.1 J/cm2 and 1 J/cm2. The device further includes a blade affixed to the applicator, the blade being constructed to fit smoothly against and to be swept over a skin surface that has been subjected to the emitted electromagnetic energy from the source of electromagnetic energy, to thereby mechanically remove hair from the skin surface.
Claims32
A device for removing hair, comprising:
- an applicator sized and configured to be held in a hand of a user;
- a reservoir coupled to the applicator and constructed to hold a depilatory composition and to release the depilatory composition onto the user's skin
- an energy emission assembly coupled to the applicator and configured to apply diffused electromagnetic energy to a surface of the user's skin;
- and
- a blade affixed to the applicator, the blade being constructed to fit smoothly against and be swept over the surface of the skin which has been subjected to the depilatory composition and the diffused electromagnetic energy emitted by the energy emission assembly.
A method for removing hair comprising the following steps:
- introducing a depilatory composition from an applicator onto a skin surface, wherein the depilatory composition comprises at least one of a thiol component and a ceteareth component;
- thereafter
- applying diffused electromagnetic energy to the skin surface where the depilatory composition has been introduced, wherein the electromagnetic energy is applied with an energy emission assembly, which is coupled to the applicator, for a duration of at least three seconds and wherein the diffused electromagnetic energy reacts with the depilatory composition to cause at least partial disruption of at least one of hair follicles and hair cuticles on the skin surface;
- and thereafter
- mechanically removing hair from the skin surface with a blade affixed to the applicator.
