Abstract

See full text

The present invention provides a process for the destruction of unwanted human hair. Hair ducts in a section of skin in which the unwanted hair are growing is contaminated with a contaminant having a high absorption at at least one frequency band of light. The skin section is then illuminated with light at the frequency band of high absorption so as to impact sufficient energy to the contaminant so as to cause death to the hairs growing in the ducts. In a preferred embodiment the contaminant is a mixture of 1 micron graphite particles in mineral oil and each section is illuminated with about 5 laser pulses at 1.06 micron wavelength produced by a Nd:YAG laser, each pulse having an energy density of about 3 Joules/cm.sup.2 and a pulse width of about 10 nanoseconds. In another preferred embodiment the hairs in the section of skin being treated are pulled out prior to application of the contaminant so as to provide more space for the contaminant in the hair duct. In still another preferred embodiment a portion of the hairs below the skin surface is removed with a depilatory. In still another preferred embodiment C.sub.60 molecules, buckey balls, are the absorbing elements in the contaminant.
