Abstract
Treatment systems, methods, and apparatuses for treating acne, hyperhidrosis, and other skin conditions are described. Aspects of the technology can include cooling a surface of a patient's skin and detecting changes in the tissue. The tissue can be cooled a sufficient length of time and to a temperature low enough to affect glands or other targeted structures in the skin.
Claims25
A method for treating a subject's exocrine glands, comprising:
- cooling a surface of a subject's skin with a cooling device to produce a freeze event in a portion of the skin with exocrine glands, the surface of the skin being cooled to a temperature higher than about −40 degrees C.;
- detecting the freeze event in the patient's skin;
- and
- controlling the cooling device and other treatment parameters to continue to cool the subject's skin after detecting the freeze event and to maintain at least a partially frozen state of the portion of the skin for a period of time long enough to alter a level of production by the exocrine glands, the partially frozen state of the portion of the skin is maintained without injuring the epidermis underlying the cooling device, and the period of time being longer than about 10 seconds.
1 more element
A method for treating glands of a subject, comprising:
- cooling a surface of a subject's skin to produce a cooling event at a target region with the glands, the surface of the skin being cooled to a temperature higher than −40 degrees C.;
- and
- controlling a cooling device and other treatment parameters to cool the surface of the skin for a period of time and to a temperature sufficiently low to injure the subject's dermis and the glands therein but without injuring the subject's epidermis and without injuring the subject's subcutaneous adipose tissue, the period of time being less than about 30 minutes.
