Acne (propionibacteri and acne) can cause surface damage. After being irradiated with light with a wavelength of 4 0 to 4 50 nm, it can inhibit acne bacteria. Among them, light with a wavelength of 4 0 to 4 2 Onm has the most effective effect on inhibiting acnes. Good, but light with a wavelength of 4 0-4-5 Onm will darken the skin (tanning) to produce melanin, so the use of a wavelength of 4 0-4 5 Onm to accurately control various optical parameters (Optical parameter) when treating facial blister, For example: the light dose and the irradiation time, etc .; the wavelength of 45 0-6 3 0 is also slightly effective for inhibiting acne bacteria; the light of wavelength 6 30-8 9 0 dish can promote wound healing and reduce wrinkles.

The patent of US Pat. No. 5,549,660 uses red light emitting diodes to treat facial blisters, but the red light has a poor inhibitory effect on acnes in deeper parts of the skin. At the same time, the treatment time is longer and it will increase the skin. The chance of scarring.

U.S. Patent No. 6641600 discloses a method of treating facial blister with a light tube emitting 4 0 ~ 4 5 On m and 5 8 9-6 5 9 nm light, but the blood will absorb a large number of wavelengths 4 0 ~ 4 5 Onm light. Therefore, if the light with a wavelength of 400 to 450 nm cannot penetrate deeper skin, it will lead to a longer treatment time and increase the chance of skin scarring.

The patent of Taiwan Patent No. TW511514 is a blue light emitting diode made with 400 ~ 4 2 0 and a red light emitting diode with 6 0-8-9 leg for treating facial blisters.

The US Pat. No. 5,360,426 patent is a laser device that controls a laser using a pressure sensor provided on an outer surface of said holder.

The patent of Taiwan Patent No. TW561896 is to use a light sensor to make the light source emit light to treat the skin and calculate the treatment time. The disadvantage is that the light with a wavelength of 400-4 5 Onm cannot penetrate the deeper skin, resulting in its treatment time. Longer, it will increase the probability of skin scarring. Although it has a liquid crystal display panel to display the irradiation time, it cannot display the cumulative number of irradiations, which is its disadvantage.

The patent of US Pat. No. 5,968,033 is a phototherapy device. A ball lens is set in a grip to transmit light to the ball lens. At the same time, the ball lens is pressed into the skin to improve light and skin. Coupling efficiency, a spring is placed behind the spherical lens, and the amount of light coupling into the skin is controlled by the degree of spring force, but the spherical lens will roll and the face is uneven, so it is not suitable for face use In particular, it is used on the nose or near the eyes, and the skin on the forehead is thin, so it is not suitable for the forehead.

EP0885629, a high-brightness lamp (flash lamp) is used, and a light guide tube (1 ig t guide) is used to transmit light to the skin. The front end of the light guide tube is a convex curved end. The convex end presses haemoglobin away from the treatment site to increase light penetration.

C (X) = C (0) (K) exp (-X /Delta)....I ₀

COO: concentration of light at skin thickness X; C (0): concentration of light of the incident light source;

K: constant (constant);

X: skin thickness;

Delta = 1 // ~ (3 μ a (μ a + μ s ^; ));

μ a [cm-1]: absorption coefficient;

μ s, = μ s (1-g);

μ s' [cm-1]: reduced scattering coefficient; μ s [cm-1]: scattering coefficient;

g: anisotropy coefficient;

Assume that the skin of thickness X is pressurized with a certain pressure P, which can be expressed by formula II:

Δ X = (X / E) P .... II.

Δχ _: deformation (deflection);

P: pressure applied to the skin;

X: skin thickness;

Therefore, from formula I, we know that as the skin thickness X increases, C (X) exhibits an exponential decay. From formula I and formula II, we can know that pressing the skin with a certain pressure P can make the skin thinner and greatly improve light penetration. Depth of penetration through the skin, while pressing the skin with a certain pressure, the oxygen-carrying heme in the surface layer of the skin can be discharged to reduce the absorption of light by the oxygen-carrying heme, so as to greatly increase the depth of light penetrating the skin, so it can greatly Increase the penetration rate of light to the skin, but pressing the skin for a long time with a certain pressure P will cause the skin to turn red. Therefore, the time for pressing must be accurately controlled (irradiation time 132), and the pressure P is preferably 2.8 ~ 280mBar, pressure P is another preferably 14 ~ 168mBar, pressure P is preferably 19.6 ~ 98mBar, pressure P is another preferably 25.2 ~ 98mB _ar , pressure P is another preferably
