Embodiment Construction

[0033] According to an exemplary embodiment of the present disclosure, "fractional cryotherapy" may be used to gradually reduce the overall dullness of an area of ​​skin due to excess pigmentation. Tiny areas of skin can be brought into contact with cold objects to inhibit the formation and / or expression of pigment in the underlying layers of the skin. The effect lightens the treated area permanently and gradually.

[0034] figure 1An exemplary device 100 for producing a controlled amount of hypopigmentation in skin tissue according to an exemplary embodiment of the present disclosure is shown. The exemplary device 100 may include a plurality of protrusions 110 coupled to a base 120 . The protrusion 110 may be in thermal communication with the base 120 . In certain exemplary embodiments, protrusion 110 and base 120 may be formed from a single material. An insulating handle 130 may be attached to the base 120 to facilitate handling and positioning of the device 100 . In ad...

Abstract

Exemplary embodiments of the present disclosure provide method and apparatus for effecting (e.g., lightening) an appearance of skin by cooling or freezing small separated surface regions of the skin to produce regions of local hypopigmentation. The width of the regions can be, for example, smaller than about 1 mm or 0.5 mm, and a distance between these frozen regions can be greater than about 3 times the width of the regions. An exemplary apparatus can be provided that includes a plurality of spatially-separated thermally conductive arrangements that can be affixed or otherwise coupled to a base. For example, the conductive arrangements can be regions of conductive material provided in or proximal to a thermal insulator, or thermally conductive protrusions affixed to the base.; The conductive arrangements can be cooled and then contacted with the skin surface to produce the small regions of hypopigmentation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 087,036, filed August 7, 2008, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to lightening the appearance of skin tissue using cooling or cryogenic techniques, and more particularly to cosmetic methods and devices that can facilitate such lightening. Background technique [0004] Hyperpigmentation of the skin can cause dark areas such as freckles, age spots, café-au-lait spots, or bags under the eyes. Hyperpigmentation can result from a variety of factors such as UV exposure, aging, stress, and more. These factors can lead to an overproduction of melanin in the skin by melanocytes, or melanogenesis, which can lead to the formation of hyperpigmented areas. [0005] There may be a need for cosmetic products that lighten the appearance of the skin, eit...
