Abstract

A method for treatment and modification of material including biological material using an electromagnetic energy source directed to apply the energy to a region of the material, so as to modify and treat a portion of the material in the region. Preferably, an interaction-modifying substance is in the treated region prior to the interaction.

Claims

1. A method for treating acne and cleaning hair follicle openings of unwanted material, the method comprising the steps of:

applying to the skin and the follicle openings in the skin a substance capable of absorbing energy and expanding under the influence of applied energy;

applying to the skin and the follicle openings in the skin a substance of high reflectiveness; and

applying energy to the expanding substance and the substance of high reflectance;

whereby the applied energy is substantially reflected from the skin, substantially propagates through the hair follicles and is absorbed by the expanding substance causing the expanding substance to expand, thereby enhancing the opening of the hair follicles.

2. The method for treating acne of claim 1 further comprising the step of removing from the skin surface, except for the hair follicle openings, the expanding substance.

3. The method, for treating acne of claim 1, wherein the step of applying a substance of high reflectance comprises applying a substance having reflective particles of a size too large to generally fit within sweat pores but small enough to fit within the hair follicle openings.

4. The method for treating acne of claim 1, wherein the step of applying a substance of high reflectance comprises applying a substance having reflective particles of a size between approximately 30 μ

m and approximately 80 μ

m.

5. The method for treating acne of claim 1, further comprising the step of removing hair from the skin area to be treated.

6. The method for treating acne of claim 1, wherein the applying energy step comprises applying short pulse electromagnetic radiation.

7. The method for treating acne of claim 1, further comprising the step of dispersing the expanding substance within the follicles by applying ultrasound to the expanding substance to move it into the follicles.

8. The method for treating acne of claim 1, wherein the step of applying energy comprises applying heat energy.

9. The method for treating acne of claim 1, wherein:

the step of applying energy comprises applying laser energy; and

wherein the expanding substance absorbs the applied laser energy, converts it into thermal energy and expands.

10. The method for treating acne of claim 1, further comprising the step of removing hair from the follicles prior to application of the energy absorbing substance.

11. The method for treating acne of claim 1, wherein the step of applying a substance capable of absorbing energy and expanding comprises the steps of applying an energy absorbing substance and a thermal expansion substance.
