How does laser treat skin problems?
Laser is a kind of light, its wavelength is long or short, and it is called laser. Just like the same thing, there are long and short, thick and thin. Our skin tissue can absorb different wavelengths of laser light with different effects.
What kind of skin problems are suitable for laser treatment?
The targets for blackening include freckles, sunburns, superficial age spots, flat and superficial moles, etc. Although lasers can remove blackheads, multiple treatments are required, and the number of times depends on the color and depth of the spots and moles.
Note: The area, depth and position of the mole need to be evaluated by a professional doctor to see if it is suitable for laser treatment, etc. For large and thick moles, surgical removal is recommended. Black moles located on the lips, palms and soles of the feet are not recommended for laser removal, as the risk of malignancy is high.
Remove tattoos and eyebrows
The Q‐Switched Nd:YAG laser delivers light of specific wavelengths in very high peak energy pulses which are absorbed by the pigment in the tattoo and result in an acoustic shockwave. The shockwave shatters the pigment particles, releasing them from their encapsulation and breaking them into fragments small enough for removal by the body. These tiny particles are then eliminated by the body.
Fractional lasers can help remove scars and pimples. Generally, it takes more than one month of treatment to see obvious results, and multiple treatments are also required.
remove red blood
Superficial telangiectasias of the skin, which can be effectively removed by laser. However, the therapeutic effect is affected by the depth of the blood vessels, and the deep hemangioma cannot be completely removed.
Hair goes through three phases: anagen, regression, and telogen. Lasers can only destroy most of the growing hair follicles and a very small part of the degenerative hair follicles, so each treatment can only remove 20% to 30% of the hair. Generally, armpit hair, leg hair, and bikini area need to be treated 4 to 5 times, while lip hair may need more than 8 treatments.
How does pulsed light treat skin problems?
Pulsed light, also a kind of light, is a high-energy flash with multiple wavelengths, which can be understood as a combination of commonly used lasers.
The so-called photon rejuvenation actually uses intense pulsed light commonly known as “photons” to improve the skin’s pigmentation and flushing problems, while improving the skin’s luster and texture. The whole process of photorejuvenation is simple and slightly painful, and it does not affect normal life and work after treatment.
