A system for treating a selected dermatological problem and a head. The head may include an optical waveguide having a first end to which EM radiation appropriate for treating the condition is applied. The waveguide also has a skin-contacting second end opposite the first end, which is in contact with the skin, and has a reflection aperture which is substantially as great as the radiation back-scatter aperture from the patient's skin. The portion of the back-scattered radiation entering the waveguide is substantially internally reflected therein, with a reflector being provided. The reflector may be angle dependent so as to more strongly reflect back scattered light more perpendicular to the skin surface than back scattered radiation more parallel to the skin surface. The head may also have a mechanism for forming a reflecting chamber under the waveguide and drawing a fold of skin therein.
1. A dermatological system, comprising: an optical waveguide for transmitting radiation received at a first end thereof to a second end configured to directly contact a subject's skin surface so as to irradiate a portion of the skin, anda reflecting plate adapted to contact a portion of the skin sur
1. A dermatological system, comprising: an optical waveguide for transmitting radiation received at a first end thereof to a second end configured to directly contact a subject's skin surface so as to irradiate a portion of the skin, anda reflecting plate adapted to contact a portion of the skin surface and surrounding at least a portion of said second waveguide end, said reflecting plate returning at least a portion of radiation backscattered from the irradiated skin portion to the subject's skin. 2.

A dermatological system according to claim 10, wherein said waveguide further comprises a chamber optically coupled to the second end for internally reflecting at least a portion of backscattered radiation extending through the second end into said chamber back to the patient's skin. 12. A system for treating a dermatological condition located in a volume of a patient's skin, comprising: a solid optical waveguide having a first end for receiving radiation generated by a radiation source and a second end configured to directly contact a patient's skin, said waveguide transmitting said received radiation from the first end to the second end for application to the patient's skin, anda reflector disposed within said waveguide for returning at least a portion of backscattered radiation entering the waveguide back to the patient's skin, anda chamber optically coupled to the first end of the waveguide for internally reflecting at least a portion of backscattered radiation extending through the second end of the waveguide into said chamber back to the patient's skin. 13. A system according to claim 12, wherein said reflector comprises reflecting side walls of said waveguide, said reflecting walls returning at least a portion of radiation applied to the patient's skin that is retroreflected into the waveguide back to the patient's skin. 14. A system according to claim 12, wherein said second end of the waveguide has an aperture at least substantially as large as a backscatter aperture of radiation backscattered from the patient's skin. 15. A system according to claim 14, wherein said reflector has a reflection aperture D at least substantially as great as said backscatter aperture. 16. A system according to claim 12, wherein said reflector comprises at least a portion of said second end of the waveguide formed as a reflection plate. 17. A system according to claim 12, wherein said reflection plate has a concave shape. 18.
