What is IPL machine used for?

Intense pulsed light (IPL) is a cosmetic skin treatment. People may use it to reduce the signs of aging or remove unwanted hair. Other uses include reducing the appearance of scars, lightening darker patches of skin, and improving the appearance of spider veins. IPL works in a similar way to laser therapy.

Intense pulsed light (IPL) is a kind of broad spectrum visible light with special wavelength, which has a soft photothermal effect. At first, it was mainly used for clinical treatment of skin telangiectasia and hemangioma in dermatology.

Basic introduction

·Chinese name: intense pulsed light

·Foreign name: IPL

·Type: wide spectrum visible light

·Purpose: clinical treatment of skin telangiectasia in dermatology

·Features: Soft photothermal effect

brief introduction

Intense pulsed light is a continuous, multi wavelength, non coherent light. The intense pulsed light therapeutic instrument with a wavelength range of 500~1200 nm can select the wavelength through the filter, so it can selectively remove pigment spots and occlude blood vessels,

Function of removing hands and wrinkles. Intense pulsed light therapy for skin wrinkles, pigmentation, telangiectasia and other changes caused by light aging

This technology is also known as Photorejuvenation.


The light source of strong pulsed light is a powerful arc lamp, which emits light of all wavelengths. Due to the significance of short wavelength light in skin beauty

It is not big, so crystal filter is used to filter short wavelength light, while the reserved light is strong pulse light, and the general wavelength is 500~120

Onm, if 515nm filter is selected, the output wavelength is 515-1200nm, and 640nm filter is selected

The output wavelength is 640~1200m. The commonly used filters are designed according to the therapeutic purpose.


Selective absorption of light+strong heat of light

With multi wavelength, strong pulse and wide spectrum, the quantized decomposed color light will form light quantum, and the quantized decomposed light quantum will be used to irradiate the skin

After that, it can reach all levels of the skin and decompose abnormal pigment cells; Destroy hair follicle; Close abnormal blood vessels; At the same time, it can stimulate the proliferation of collagen and rearrange elastic fibers, so as to achieve the effect of freckle removal, ER nano light hair removal, red blood removal, whitening and rejuvenation. Remove freckles and take abnormal pigments out of the body by metabolism.


Wrinkle removing – effectively eliminate and relieve wrinkles of different degrees in the eyes and forehead

Skin rejuvenation – shrink pores, improve skin texture and increase skin elasticity:

Firming skin – improve skin elasticity and skin smoothness;

Whitening – remove freckles, age spots, acne, etc., decompose melanin, and make skin white

Have an effect

Strong pulsed light can have two effects on the skin:

Biological stimulation: the photochemical effect produced by the strong pulse light acting on the skin can cause the chemical changes of the molecular structure in the collagen fibers and elastic fibers of the dermis, and restore the original elasticity. In addition, its photothermal effect can enhance blood vessel function, improve circulation, and achieve the therapeutic effect of eliminating wrinkles and shrinking pores.

Photothermal decomposition principle: Since the content of pigment groups in the diseased tissues is far more than that in the normal skin tissues, the temperature rise after absorbing light is also higher than that of the skin. Use their temperature difference to seal the diseased blood vessels, break and decompose pigments without damaging normal tissues.

Therefore, IPL is used in the medical and beauty industry to treat acne, age spots, and pigmentation, and improve the skin. It is widely welcomed by beauty lovers.

Relevant information

The original name is light quantum, also called ER nano light. The quantum of electromagnetic radiation and the gauge particle that transmits electromagnetic interaction are recorded as y. Its static quantity is zero, it is not charged, its energy is the product of Planck constant and electromagnetic radiation frequency, it runs at the speed of light c in vacuum, its spin is 1, and it is a boson. As early as 1900, when M Planck explained the energy distribution of blackbody radiation, he made a quantum hypothesis that the energy exchange between matter oscillator and radiation was discontinuous, one by one, and each energy was hv; In 1905, A Einstein further proposed that light waves themselves are not continuous but have particle characteristics, which Einstein called light quantum: In 1923, AH Compton successfully explained the Compton effect of wavelength changes when X light is scattered by matter with the concept of light quantum, thus the concept of light quantum was widely accepted and applied, and was officially named as photon in 1926. After the establishment of quantum electrodynamics, confirm

Photon is a medium particle that transmits electromagnetic interaction. Charged particles interact by emitting or absorbing photons. Positive and negative charged particles

Subpairs can be annihilated into photons, and they can also be generated in electromagnetic fields.

Photons are particles of light that carry energy. The energy of a photon is related to the wavelength. The shorter the wavelength, the higher the energy. When one

When a photon is absorbed by a molecule, an electron gains enough energy to transition from the inner orbital to the outer orbital, with an electronic path

The migrating molecules change from the ground state to the excited state.

Photon has energy, momentum and more mass. According to the mass energy equation, E=MC2=HV, M=HV/C2 is obtained

Since a photon cannot rest, it has no rest mass. The mass here is the relativistic mass of the photon.

Photon is the basic particle that transmits electromagnetic interaction, and it is a gauge boson. Photon is the carrier of electromagnetic radiation, and in quantum field theory, photon is considered as the medium of electromagnetic interaction. Compared with most elementary particles, the static mass of photons is zero, which means that their propagation speed in vacuum is the speed of light. Like other quantum, photon has wave particle duality: photon energy table

It shows the refraction, interference, diffraction and other properties of the classical wave, while the particle nature of the photon shows that it is not classical when interacting with the matter

In that way, the particle of can transfer energy of any value, while the photon can only transfer quantized energy. For visible light, the energy carried by a single photon is about 4 * 10-19 joules, which is enough to stimulate a molecule of the photoreceptor cell on the eye, thus arching vision. In addition to energy, photons also have momentum and polarization state, but a single photon has no definite momentum or polarization state
