Abstract
Methods and systems for treating skin for aesthetic or health or other purposes are described. According to various embodiments, photoresponsive materials and light are delivered in controlled fashions to produce a patterned distribution of one or more material in or upon the skin.

38. A method of producing a patterned distribution of material on a skin surface region, comprising:
-
delivering at least one photoresponsive material to a skin surface region of a subject;
delivering light to the skin surface region according to a first pattern, the light having a first wavelength band and peak or time-average flux or fluence sufficient to produce a first response in the at least one photoresponsive material;
delivering light to the skin surface region according to a second pattern, the light having a second wavelength band and peak or time-average flux or fluence sufficient to produce a second response in the at least one photoresponsive material, said second response being modified by said first response in the areas of overlap between said first pattern and said second pattern; and
repeating one or more steps of delivering a photoresponsive material to the skin surface region or delivering light to the skin surface region, wherein at least one of said one or more repeated steps produces a response that is modified by a previous response of the skin region to delivery of one or more of photoresponsive material and light. - View Dependent Claims (39, 40, 41, 42, 43, 97, 98, 99)

55. A method of modifying a skin surface region, comprising:
-
forming at least one volume of photoresponsive material on a skin surface region of a subject; and
forming a multi-layer structure of a light-modulating material within said at least one volume of photoresponsive material, including forming each layer of said multi-layer structure by delivering a patterned distribution of light to a respective level above said skin surface region within said at least one volume of photoresponsive material, wherein said patterned distribution of light causes transformation of said photoresponsive material to said light-modulating material. - View Dependent Claims (56, 58, 65, 69, 100, 101, 102)

70. A method of forming a multi layer structure on skin surface, comprising:
-
forming a first layer of patterned material within at least one volume of photoresponsive material formed on the skin surface at a first level above the skin surface by delivering a first patterned distribution of light to said at least one volume to cause a first transformation of said photoresponsive material at said first level; and
forming a second layer of patterned material within said at least one volume at a second level above the skin surface by delivering a second patterned distribution of light of to said at least one volume to cause a second transformation of said photoresponsive material at said second level. - View Dependent Claims (71, 72, 89, 90, 93, 96, 103, 104, 105, 106, 107, 108, 109)
