Abstract
A laser method for selective photocoagulation of subsurface skin (dermis) for the purpose of increasing skin tone, reducing wrinkles, removing hair, removing tattoos or treating varicose veins without damaging the skin surface (epidermis). A diffuser lens in the laser apparatus is employed to focus the laser energy to the dermis. The laser apparatus includes a highly transmissive contact tip and cooling means to reduce heat build-up in the contact tip, as monitored by a thermocouple mechanism. The present invention can be used alone or in conjunction with superficial laser resurfacing or chemical peels to increase skin tone.
