193nm: The black line from left to right is the absorption of protein. The femtosecond laser 193nm laser irradiates the protein of the cornea, which makes the cornea thin, mainly because the protein is absorbed and vaporized, which is used for myopia treatment.

308nm: The skin will turn black when exposed to ultraviolet rays. It is used to treat vitiligo. It should be treated with a 308nm excimer laser to stimulate the activity of tyrosinase, and then generate new melanin. We have a melanin curve below 308nm, which increases with the wavelength. , the melanin begins to decline.

532nm: 532nm treatment is easy to return to black, 532nm is closer to the range of violet light, the closer it is to the purple wave, the easier it is to black after irradiation, 532nm treatment is also prone to bleeding, we can easily see the oxyhemoglobin line, deoxygenation The hemoglobin line (hemoglobin double line) and the melanin line are tangled. 532nm can treat superficial layers including freckles and senile plaques (seborrheic keratosis). Do not hit deep spots. After hitting the bleeding, there will be an inflammatory reaction. For example, after a fall, the wound location becomes black, and 532nm must be operated according to the indications.

LED red and blue light: red light can promote protein growth, blue light can sterilize, and purple light can tan the skin. The irradiation time has been in accordance with the standard time, not more than 30 minutes.

Between 694nm-755nm: We found that at this time, the hemoglobin double line has obvious bifurcation with the melanin line, that is to say, the melanin on the skin has an obvious reaction in this band, and it is not easy to bleed.

585nm: Pulsed laser, when you look at the picture, you can see that it is the position closest to the blood vessels. It has the greatest effect on blood vessels, including port-wine stains. 585nm is a long-pulse laser without mechanical blasting. When it is irradiated on the blood, the temperature of the blood increases, When the temperature rises to above 60 degrees, the blood vessel wall is cooked, and the inactivation leads to closure, the blood does not flow, and the blood vessel wall is absorbed and discharged around, so the skin turns white.

808nm - 810nm: Laser for Hair Removal

1064nm: 532nm is halved by 1064nm laser. 1064nm breaks, decomposes and absorbs melanocytes through mechanical blasting, and is used to remove tattoos, pigments, etc.

1550nm, 1927nm, 2940nm, 10600nm are the first infrared laser skin rejuvenation used in Korea to avoid pigmentation after treatment.

CO2 Fractional Laser: Used to treat scars, stretch marks, acne, pimples, peeling principle, can be done once a year for skin peeling.

2940 erbium laser: mainly used for vaginal privacy, the erbium laser has the highest water absorption rate (the position of the erbium laser and water is the closest in the picture above), the energy of the erbium laser is reduced when used on the face, because the water on the surface of the skin is limited, after hitting The water evaporates immediately, and then vaporizes after hitting it again. It is not suitable for skin rejuvenation; (oral cavity, nasal cavity, vagina, rectum) The vagina has the most mucosal tissue and the most water, so it is used in the mucosal tissue to stimulate the vaginal wall to tighten; 2940 can Do it around the eyes, it will be absorbed immediately after doing it, and the skin will tighten.

980nm: for the treatment of blood vessels, relatively large arteries, spider vein removal.

755nm: The latest PICO laser, mainly used to remove various pigments, tattoos, etc., with little damage to the skin and no blackening.
