Description
- This invention relates to methods and devices for treating skin.
- There are many medical and cosmetic treatments of skin that utilize heating a region of skin to be treated. Among these are hair removal, treatment of vascular lesions and skin rejuvenation. In these treatments, a volume of skin tissue to be treated is heated to a temperature sufficiently high to achieve a desired effect, which is typically in the range of 45-60° C. One method that has been used for heating the epidermal and dermal layers of the skin is pulsed radio-frequency (RF) energy. In this method, electrodes are applied to the skin and an RF voltage pulse is applied across the electrodes. The properties of the voltage pulse are selected so as to generate an RF current pulse in the tissue to be treated that heats the tissue to the required temperature. For example, U.S. Pat. No. 6,749,626 discloses use of pulsed RF energy for inducing collagen formation in the dermis.
- When an RF current pulse is used to heat a volume of tissue, the temperature of the tissue volume rises from body temperature to the required temperature within the duration of the pulse, which is typically of the order of 100 msec. The temperature of the tissue volume thus rises vary rapidly. Since the final temperature will actually depend on the electrical properties of the tissue volume which vary from individual to individual, the rapid rise in temperature of the tissue volume limits control of the tissue heating. Moreover, the rapid rise in temperature prevents the user from stopping the treatment should the tissue volume become overheated. Thus, using an RF pulse to heat the skin carries a risk of overheating the skin which could result in permanent scarring or other damage to the skin surface. Such damage to the skin includes, for example, a first degree or higher burn, blisters, or blood coagulation.
- The present invention provides a method and system for heating a sub-dermal tissue volume. In accordance with the invention an RF current is generated in a tissue volume to be treated that raises the temperature of the tissue volume to a desired temperature above its initial temperature in a period of time that exceeds 0.5 sec. The slow rise in temperature allows the user to control the skin temperature and to avoid overheating of the skin. The invention is particularly useful for skin treatments requiring the tissue volume to be heated to a temperature in the range of 45° C. to 60° C. Such treatments include, for example, skin rejuvenation, collagen remodeling and contraction, skin tightening, wrinkle treatment, subcutaneous tissue treatment, cellulite treatment, pore size reduction, skin texture and tone improvement, acne treatment and hair removal.
- In one embodiment of the invention, a pair of RF electrodes is applied to the skin surface, and an RF energy pulse is applied to the skin surface having a duration and power selected so as to heat the skin surface to a predetermined temperature within an amount of time exceeding 0.5 sec. For example, an RF energy pulse having a power range of 1-10 Watts could be used. In this case application of RF energy would heat the tissue volume to a temperature in the range of 40°-60° C. within 0.5-10 sec. The electrodes could be positioned at a first location in a skin region to be treated and the RF energy pulse applied to the first location. The electrode pair could then be repositioned on the skin surface at another location in the region to be treated and the procedure repeated. In another embodiment of the invention, continuous wave (CW) RF energy is applied to the skin surface and by a pair of electrodes which is displaced over the skin surface at a displacement speed that sequentially heats a tissue volume adjacent to the electrodes to the predetermined temperature in a time that exceeds 0.5 sec. For example, CW RF energy having a power range of 2-10 Watts could be used. In this case, a displacement speed of about 0.5-1.0 cm/sec would heat the tissue volume to a temperature in the range of 45°-60° C. in a time that exceeds 0.5 sec. Quasi-CW RF energy may also be used in which a train of RF pulses is applied to the skin surface, where the train has a frequency and the pulses have durations and powers, so as to heat the tissue volume to be treated to a predetermined temperature in a period of time that exceeds 0.5 sec.
- The system of the invention comprises two or more RF electrodes and an RF generator configured to apply an RF voltage across at least a pair of electrodes, where the RF voltage has a power selected to heat a tissue volume to a predetermined temperature in a time period that exceeds 0.5 sec., when an electrode pair is applied to the skin surface over the tissue volume. The RF generator may be configured to deliver a pulse of RF energy having a duration exceeding 0.5 sec. Alternatively, the RF generator could be configured to deliver CW or quasi-CW RF energy to the electrodes, in which case, the electrodes are displaced over the skin surface during delivery of the RF energy. In a preferred embodiment of the system, a pair of RF electrodes is included in a hand held applicator. A user treating his own skin with the system of the invention may simply displace the applicator over the skin surface in the region to be treated at a speed at which the user feels that the skin is heated but not to an extent that causes pain to the user.
- The slow heating of the skin volume by the method and system of the invention permits greater control of the tissue heating, and thus reduces the risk of overheating, and hence damaging, the tissue.
- Damage to the skin may include, for example, a first degree or higher burn, blisters, or blood coagulation. The appropriate displacement speed of the applicator over the skin is thus a function of the RF power. As the RF power increases, the movement of the applicator over the skin surface should be faster in order to avoid skin damage due to overheating of the skin.
- The system includes a control mechanism that turns off or reduces the RF energy when a condition indicative of skin overheating occurs, in order to prevent overheating of the skin that could otherwise occur if the applicator were to be displaced over the skin by the user too slowly or not at all during delivery of RF energy to the skin. In one embodiment, the control system includes a temperature sensor, such as a thermistor or thermocouple that measures the skin temperature during delivery of RF energy. The skin temperature is monitored by the system which automatically turns off the RF energy when the skin temperature exceeds a predetermined threshold.
- In another embodiment, the system includes a motion detector that continuously monitors the movement of the applicator over the skin. An optical or mechanical device can be used for the motion detection. An accelerometer may also be used for motion detection. In this embodiment, the system turns off the RF energy when the speed of the applicator is below a predetermined threshold or when the applicator is applied to the skin and not moved for a period of time which is longer than a predetermined time period. In a preferred embodiment, the control mechanism involves measuring the electrical impedance of the skin between a pair of RF electrodes. A processor continuously calculates the skin temperature from the impedance measurements and turns off the RF energy when the calculated temperature is above a predetermined threshold.
- Thus, in one of its aspects, the invention provides a system for heating a tissue volume under the skin surface of an individual from an initial temperature to a treatment temperature in a treatment time period exceeding 0.5 sec, the treatment temperature being in the range of 40°-60° C., comprising:
-
- (a) an applicator;
- (b) an RF generator configured to provide a continuous wave RF voltage energy or a quasi-continuous wave RF voltage across a first electrode and a second electrode, at least one electrode being associated with the applicator;
- (c) A skin temperature measuring device or an applicator motion sensor; and
- (d) a CPU configured to monitor a skin temperature or an applicator displacement speed and to turn off or reduce the RF energy when the skin temperature is above a predetermined temperature or the displacement speed of the applicator is below a predetermined speed.
- In another of its aspects, the invention provides a method for heating a tissue volume under the skin surface of an individual from an initial temperature to a treatment temperature in a treatment time period exceeding 0.5 sec, the treatment temperature being in the range of 40°-60° C., comprising:
-
- (a) providing a continuous wave RF voltage energy or a quasi-continuous wave RF energy across a first electrode and a second electrode, at least one of the electrodes being associated with an applicator;
- (b) displacing the applicator over the skin surface;
- (c) monitoring a skin temperature or an applicator motion; and
- (d) turning off or reducing the RF energy when the skin temperature is above a predetermined temperature or the displacement speed of the applicator is below a predetermined speed.

FIGS. 2 and 3 show anapplicator 2 a in accordance with one embodiment of theapplicator 2. Theapplicator 2 a contains a push-button on-off switch 16. Theswitch 16 is spring biased in an open position, so that no voltage is applied to theelectrodes switch 16 is released. When theapplicator 2 is held by a user, as shown inFIG. 1 , theswitch 16 is depressed and a continuous or quasi-continuous wave RF voltage (train of repetitive pulses) is applied between theelectrodes electrodes - The
applicator 2 a preferably, though not necessarily, includes alight source 21 which is located between theelectrodes skin 25 surface by areflector 24. Optical energy directed to the skin surface from thelight source 21 is used to specifically heat pigmented targets at the skin surface. Such skin targets include vascular lesions, varicose veins, acne, and mole marks. The optical energy may have a single wavelength or several wavelengths. The wavelengths are selected to be optimal for the color of the contrasted component of the target, and are typically in the range of 400 to 1800 nm. A filament lamp or gas filled lamp can be used as thelight source 21. Light from a laser or LED also can be used for skin irradiation. - In use, the
applicator 2 is held by the user and theelectrodes switch 16 is then depressed so as to deliver a continuous wave RF current to a section 17 of the skin between theelectrodes applicator 2 is displaced over the skin in askin region 15 to be treated so as to heat the skin region to a temperature that produces the desired treatment of the skin. - When the
applicator 2 a is used, theCPU 13 continuously monitors the electrical impedance of the skin between theelectrodes CPU 13 is configured to continuously calculate a skin temperature from the impedance measurements and to turn off the RF energy when the calculated skin temperature is above a predetermined threshold. -
FIG. 4 shows anapplicator 2 b in accordance with another embodiment of theapplicator 2. Theapplicator 2 b has several elements in common with theapplicator 2 a shown inFIGS. 2 and 3 , and similar elements are indicated by the same reference numeral inFIGS. 2 , 3, and 4 without further comment. - The
applicator 2 b hasroller 20 adjacent to the electrode pair that is positioned and dimensioned to contact the skin surface and to roll over the skin surface as the applicator is displaced over the skin surface. Theroller 20 has a plurality of evenly spacedradial markers 22 on itsedge 24. Theedge 24 is illuminated by light from alaser 26. Light reflected from theedge 24 is detected by aphoto cell 28 that generates an electric signal indicative of the intensity of the reflected light. Due to the presence of theradial markers 22 the intensity of the reflected light, and hence the intensity of the electric signal, varies cyclically as the roller rolls over the skin surface. The electrical signal is continuously monitored by theCPU 13 which is configured to calculate a displacement speed of theapplicator 2 b over the skin surface from the periodicity of the electrical signal which is proportional to the displacement speed of the applicator. TheCPU 13 in this embodiment is configured to turn off the RF energy when the displacement speed is below a predetermined value. - When the CPU determines that the skin temperature is above the predetermined temperature, the processor may generate a sensible signal, such as sounding an
alarm 15 at a pitch indicating to the user that the displacement speed is too low and that the RF energy has been turned off. Similarly, if theCPU 13 determines that the skin temperature is below a second predetermined value that is required to produce the desired skin treatment (for example, 45° C. to 60° C., which maybe input to theCPU 13 prior to the treatment), the processor may generate a sensible signal, such as sounding thealarm 15 at another pitch indicating to the user that the displacement speed should be increased. - The displacement velocity of the
applicator 2 over the skin is determined so that the skin section between the electrodes is heated to a temperature that produces the desired skin treatment, but does not damage the skin. The desired displacement speed can be determined, for example, using the equation -
- where P is the power of the continuous RF current, L is the spacing of the electrodes, d is the penetration depth of the RF energy, c is the specific heat of the treated tissue, ρ is the mass density of the tissue, and ΔT is the required temperature increase. Thus, for example, if the RF power is P=5 W, the spacing of the electrodes is L=1 cm, the RF penetration depth is d=0.25 cm, cρ=4 J/cm3/° K and ΔT=10° C., the applicator displacement speed should be about 0.5 cm/sec. in order to achieve the desired heating in amount of time in slightly more than 0.5 sec. If a mono-polar electrode system is used, the power should be lower to avoid damage to sub-dermal tissue.
- The
system 1 may be used with the following exemplary parameter values: - An RF power in the range of 2-10 W.
- An energy delivery mode that is CW or Quasi-CW.
- An RF frequency in the range of 0.2-10 MHz.
- An optical energy spectrum in the range of 400-1800 nm.
- Optical energy power in the range of 1 to 20 W/cm2.
