Abstract:
A process for inhibiting growth in a section of human skin, of a plurality of hairs growing in hair ducts from follicles at the bottom of said ducts and being nourished by skin tissue immediately surrounding said follicles, essentially without damage to skin tissue except to said skin tissue immediately surrounding said follicles, comprising the steps of:a. selecting a contaminant including a dye having a high optical absorption of at least one frequency band of light which will penetrate said section of skin,b. applying said contaminant to the surface of said section of skin in such a manner as to cause a portion of said contaminant to infiltrate said hair ducts and stain the hair follicles, andc. illuminating said section of skin with said at least one frequency band of light, a significant portion of which penetrates the section of skin and is absorbed in said dye in said hair ducts causing a reaction which inhibits growth of said hairs by causing heating of said follicles or of the skin tissue feeding said follicles.
