1. A device for treatment of skin, comprising:
- an energy delivery system that directs energy to a target tissue for a predetermined time period and at a predetermined fluence such that a peak temperature reached in the target tissue causes a thermally mediated response resulting in transient erythema and/or mild edema, without blistering.

16. A method for treatment of skin, comprising:
-
selecting a source of energy in which attenuation of the energy as it passes through the skin is a function of depth;
heating the skin with the energy source for a predetermined time period and with a predetermined fluence such that the energy causes thermal mediated injury in skin below the epidermis resulting in transient erythema but does not blister the epidermis. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A method for treatment of acne scars in skin, comprising:
-
heating the target skin portion with a source of energy which is uniformly attenuated with depth in skin for a predetermined time period and predetermined fluence such that the exposure time of the epidermis and the peak temperature reached by the epidermis are such that the epidermnis does not blister; and
causing thermally mediated injury in skin below the epidermis resulting in transient erythema to initiate a healing response which improves the appearance of the acne scars.

26. A method for treatment of photo damaged skin, comprising:
-
heating the skin with a source of energy which is uniformly attenuated with depth in skin for a predetermined time period and predetermined fluence such that the exposure time of the epidermis and the peak temperature reached by the epidermis are such that the epidermis does not blister; and
causing thermal mediated injury in skin below the epidermis resulting in transient erythema to initiate a healing response which improves the appearance of the photo damaged skin.

27. A method for treatment of wrinkled skin, comprising:
- heating the skin with a source of energy which is uniformly attenuated with depth in skin for a predetermined time period and predetermined fluence such that the exposure time of the epidermis and the peak temperature reached by the epidermis are such that the epidermis does not blister; and
causing thermal mediated injury in skin below the epidermis resulting in transient erythema to initiate a healing response which improves the appearance of the wrinkled skin.
- heating the skin with a source of energy which is uniformly attenuated with depth in skin for a predetermined time period and predetermined fluence such that the exposure time of the epidermis and the peak temperature reached by the epidermis are such that the epidermis does not blister; and
-
28. A method of thermal quenching of surface tissue during selective thermally mediated treatment of target tissue or structures, the method comprising the steps of:
-
delivering energy to the target tissue or structures to increase the temperature of the target tissue or structures to a predetermined treatment temperature, thereby, resulting in transient erythema; and
cooling the surface tissue or other tissue adjacent the target tissue or structures to prevent excessive heating of the surface tissue or other tissue adjacent the target tissue. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
