Abstract

Disclosed is a method of curing inflammatory acne by applying a carbon lotion onto a face covered with acne, irradiating the applied carbon lotion with a laser pulse having a pulse width of microsecond, and irradiating the applied carbon lotion with a laser pulse having a pulse width of nanosecond to sterilize acne bacilli and open skin pores clogged with sebum, thereby entirely treating the inflammatory acne. The method includes applying the carbon lotion onto epidermis to be cured and pores, irradiating the carbon lotion with a laser pulse to heat and burst the applied carbon lotion. With the method, the inflammatory acne is simply cured without scar.

Claims

1. A method of curing inflammatory acne by using a carbon lotion and a pulsed laser, the method comprising:

applying the carbon lotion onto epidermis and pores to be cured; and

irradiating the applied carbon lotion with a first laser pulse having a first pulse width to heat the applied carbon lotion; and

irradiating the applied carbon lotion with a second laser pulse having a second pulse width shorter than the first pulse width to burst the carbon lotion in the pores after the first laser pulse is irradiated,

wherein the first pulse width is in a range of 100 μ

s to 1000 μ

s,

wherein the second pulse width is in a range of 5 ns to 50 ns, wherein each of the first and second pulses have an energy density in a range from 1.5 J/cm2 to 3.0 J/cm2,

wherein a laser producing the first and second laser pulses has an oscillation wavelength of 1064 nm.

2. The method as claimed in claim 1, wherein the laser comprises an Nd:

YAG laser.

3. The method as claimed in claim 1, wherein the laser comprises a pulsed Nd:

YAG laser.

4. The method as claimed in claim 1, wherein the laser comprises an Nd:

YAG laser with a Q-switch.

5. The method as claimed in claim 4, wherein irradiating the applied carbon lotion with a second laser pulse comprises irradiating the applied carbon lotion with the second laser pulse by the Q-switch after the applied carbon lotion is irradiated with the first laser pulse.
