Abstract
A method and system in accordance with particular embodiments includes applying a substance onto skin of a human subject. A method for treating a subject's skin includes applying a hydrogel to the skin which contains the substance. The hydrogel and the skin are cooled using a cooling applicator to treat tissue via the cooling treatment by either freezing or not freezing tissue.
Claims22
A method for treating a subject's skin, comprising:
- applying a hydrogel to the skin, the hydrogel including an ice nucleating agent capable of forming ice crystals in the presence of water, the ice nucleating agent being encapsulated within a polymer structure of the hydrogel such that the ice nucleating agent does not come in direct contact with a surface of the skin;
- cooling the hydrogel and the skin with a cooling applicator to arrive at a cooling treatment temperature for the skin;
- and
- freezing the skin via the hydrogel.
1 more element
A method for treating skin, comprising:
- applying a substance to the skin, wherein the substance comprises a cross linked polymer structure and an ice nucleating agent (INA), wherein the polymer structure includes water, and wherein the INA is capable of forming ice crystals in the presence of water and is embedded within the polymer structure to prevent direct contact between the INA and the skin;
- cooling the substance and the skin with a cooling applicator to lower a temperature of the skin;
- and
- freezing the skin via the substance.
1 more element
A method for treating a subject's skin, comprising:
- applying a hydrogel to the skin, the hydrogel including a freezing point depressant and water, the freezing point depressant being encapsulated within a polymer structure of the hydrogel such that the freezing point depressant does not come in direct contact with a surface of the skin;
- cooling the hydrogel and the skin with a cooling applicator to arrive at a cooling treatment temperature for the skin.
