Abstract: A method of permanent hair removal which uses a high energy light source projected at the skin to cause death of the hair follicle by photothermolysis. The process uses either incoherent or coherent light energy. Additional melanin is added to the skin by a process which delivers the melanin to the region of the hair follicle thereby enhancing that area as a light absorbing target. Collateral damage to the surrounding skin tissue is minimized. The delivery process uses liposomes selected particularly to encapsulate and carry melanin to the target region. The invention also encompasses a general method of deleterious tissue destruction by selective introduction of melanin and subsequent photothermolysis.

Abstract: A process for the long term or permanent prevention of growth of unwanted hair. The upper portions of hair ducts (i.e. portions near the skin surface) in a section of skin are infiltrated with a contaminant having a high absorption at at least one frequency band of light. The skin is then illuminated using a process having at least two distinct phases. In a "mechanical" phase the skin section is illuminated (e.g., by a laser) with at least one short pulse of light sufficient to cause tiny explosions in the contaminant forcing portions of the contaminant more deeply into the hair ducts. During a "thermal" phase the skin section is then illuminated so as to heat the contaminant substantially without further explosion or vaporization of the contaminant. The hot contaminant heats portions of the skin tissue immediately surrounding the contaminant to a temperature high enough and for a long enough period of time to devitalize the tissue.

Abstract: 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.
