1. A method for cooling skin tissue comprising: using a cryogenic composition in a skin treatment apparatus to cool heated skin during skin treatments, the cryogenic composition including propyne in combination with one or more of the following: 1,1,3,3,3-pentafluoropropene, 1,2,3,3,3-pentafluoropro

1. A method for cooling skin tissue comprising: using a cryogenic composition in a skin treatment apparatus to cool heated skin during skin treatments, the cryogenic composition including propyne in combination with one or more of the following: 1,1,3,3,3-pentafluoropropene, 1,2,3,3,3-pentafluoropropene, or trifluoroiodomethane. 2. The method of claim 1 wherein the cryogenic composition is a mixture of trifluoroiodomethane and propyne, with trifluoroiodomethane being present in an amount of about 97% to about 99% by weight of the composition. 3. The method of claim 1 wherein using a cryogenic composition in a skin treatment apparatus to cool heated skin during skin treatments comprises: positioning an electrode of the skin treatment apparatus adjacent a skin surface, the skin treatment apparatus adapted to deliver energy via the electrode to tissue located beneath the skin surface;applying energy to tissue located beneath the skin surface via the electrode; andspraying the cryogenic composition against a non-patient side of the electrode to cool the tissue. 4. The method of claim 3 further including detecting a temperature of the electrode. 5. The method of claim 1 wherein the cryogenic composition is propyne in combination with 1,1,3,3,3-pentafluoropropene, 1,2,3,3,3-pentafluoropropene, or trifluoroiodomethane. 6. The method of claim 1 wherein the cryogenic composition is propyne in combination with 1,1,3,3,3-pentafluoropropene. 7. The method of claim 1 wherein the cryogenic composition is propyne in combination with 1,2,3,3,3-pentafluoropropene. 8. The method of claim 1 wherein the cryogenic composition is propyne in combination with trifluoroiodomethane.
