Laser mole removal
1. The principle of laser mole removal
Laser mole removal is to use the huge energy of the laser to act on the pigment tissue in an instant, so that the pigment is broken, decomposed, swallowed by macrophages, and excreted from the body with the lymphatic circulation, so as to achieve the purpose of removing the pigment.
During laser mole removal, small cracking sounds can be heard when the tissue is vaporized, and dry debris of the mole tissue protein can be seen. Every time it is vaporized, the debris on the surface must be wiped off with saline, cotton swabs or gauze to avoid unnecessary thermal damage during repeated scanning. Gasification to black disappears, and the following indications can be seen with naked eyes: coarse skin appendages can be seen on the wound of the face, in the form of white granules, most of these granular tissues are sebaceous glands; such as on the wounds of the limbs or trunk The denser connective tissue can be seen on the upper part, and the density of the tissue gradually decreases from the papillary layer of the dermis to the deep part. When the gasification continues, the appendages can be seen in the dermis and the tissue density becomes lower, and thick fiber bundles can be seen, which looks like Cotton thread soaked in water. At this time, it has reached the reticular layer of the dermis, and gasification should stop. At this time, if you still see filamentous melanin or punctate melanin extending to the deep part, you can use VersaPulseQ switch 75nm or 1 064nm laser for treatment, the spot is 2-3mm, the energy is 4-8J/cm2, and several local repeats pulse.
2. Indications for laser mole removal
Laser mole removal is effective in treating various pigment disorders, such as Ota moles, pigmented moles, bad eyebrow tattoos, eyeliner tattoos, tattoos, age spots, port wine stains, red eyebrow tattoos, tattoos, varicose vein diseases, vascular diseases, etc. Laser mole removal has different treatment times for different moles, and some times require more times.
3. Laser mole removal process
1. Doctor's diagnosis: Laser mole removal is suitable for epidermal nevus, pigmented nevus, freckle-like nevus, etc. It can be treated in general body surface areas.
2. Treatment: Disinfection-adjust the laser intensity-laser fine vaporization of the lesion-check and clean the wound surface-bandaging (generally no bandaging is required, dry exposure is sufficient).
Four, different wavelength laser to remove moles
According to experts, lasers with different wavelengths can be used for different mole spots for better targeted treatment. Let's take a look at the effect of lasers with different wavelengths in removing moles.
1. Mole removal with 532nm wavelength laser: It is suitable for the removal of superficial pigment spots on the skin around the eyes, such as birthmarks, Ota moles, moles, coffee moles, freckles, various pigmentation, eyebrow tattoos, eyeliner, and various Kinds of port wine stains, vascular lesions, etc.
2. 585nm wavelength laser to remove moles: It is suitable for various port wine stains and vascular diseases. 585nm is the strongest absorption peak of red blood cells. It is the best wavelength for the treatment of various port wine stains and vascular diseases, such as spider -shaped. Telangiectasia, hemangioma, rosacea, deep erythema, etc.
3. Laser removal of moles with 650nm wavelength: It is suitable for removing tattoos and pigmented moles. Wavelength 650nm is the absorption peak of green dye. It is the most effective for removing green pigments in professional tattoos. It can also be used to remove general pigmented moles.
4. Mole removal with 694nm wavelength laser: It is suitable for removing Ota moles, stained spots, freckles, and blue-black, black, green, and brown tattoos.
5. Laser removal of moles with 1064nm wavelength: It is suitable for deep pigmented lesions and deep-colored tattoos. 1064nm has a strong penetrating ability to skin tissues and can reach the melanin in the deep layers of the skin.
6. Laser removal of moles with a wavelength of 2940nm: It is suitable for wrinkle removal of the skin around the eyes. Its thermal damage to the skin is very shallow, only 5-10μm. The skin heals quickly, and there is basically no pigmentation after the operation. It is especially suitable for Asians and people. Darker skin.
5. Precautions for laser removal of moles
1. The wound will not be stained with water for 7-10 days after laser mole removal;
2. During laser mole removal treatment, no makeup, no alcohol, no mask, no telangiectasia and no rubbing. Pay attention to sun protection, otherwise it will produce short-term pigmentation.
3. The scab on the wound surface will fall off from the 5th day after laser mole removal. After the scab is removed, the fresh tissue is relatively delicate and cannot withstand the sun, so pay attention to sun protection. It is recommended to apply sunscreen when going out, especially in summer.
4. After laser removal of moles, the pigmentation disappears is a slow biological process. Beauty lovers must go back to the hospital for review one and a half months after the operation.
5. After laser removal of moles, care should be taken to avoid excessive sweating. Also pay attention to sun protection, the whiter the skin, the more attention should be paid to sun protection to ensure the effect of removing moles.

11. People who are pregnant , breastfeeding, have immune diseases, and those who have a heart rhythm regulator should not be treated.
6. Laser treatment of port wine stains
Laser treatment of port wine stains uses the hemoglobin in the blood vessels to selectively absorb the energy released by the laser of a specific wavelength, resulting in damage and complete destruction of the blood vessels, while the surrounding normal skin tissue is rarely absorbed, so it can achieve both elimination The ideal effect of vascular skin lesions without leaving scars.
Experts pointed out that the effect of laser treatment of port wine stains is very significant. The treatment site of laser treatment of port wine stains should be kept clean to avoid infection and friction. If there are crusts, let them fall off on their own, do not lift them by hand, otherwise the pigmentation Severe and easy to leave scars. After the scab falls off, there may be short-term local pigmentation. In order to prevent or reduce this situation, reasonable use of sunscreen and freckle products can be used.
Port wine stains
PWS is a congenital malformation of the capillaries, it is also known telangiectasia nevi and grape wine nevus. Most showed dark red or blue color of the plaques, the edge is not sharp, is not higher than the leather, the pressure of discoloration , Sometimes there is some capillary dilation on it. It usually occurs at birth or shortly after birth. It usually occurs on the exposed parts of the head, face, neck, etc., generally unilateral. As the child grows up, it increases and can gradually thicken. The color darkens, and even local hyperplasia occurs and some nodules are formed, but malignant changes rarely occur. Therefore, the main effect of the harm of port wine stains is the appearance.
Can port wine stains be completely cured?
Experts say that the laser emitted by the pulsed dye laser specifically used to treat port wine stains can penetrate the epidermis on the lesion very smoothly and enter the lesion site. The hemoglobin inside the blood vessels in the lesion area is completely under the powerful laser. Coagulation, these coagulated hemoglobin seals the abnormal blood vessels, and as a result, the diseased blood vessels in port wine stains disappear and the disease can be cured. Since this kind of laser hardly damages the skin, it will not leave scars after treatment and can be close to the true color of the skin. The interval between each treatment needs more than two months.
Port wine stains can be greatly improved after multiple treatments, and can be close to the normal skin color. And the earlier the Port Wine Stain is treated, the better the treatment effect will be.
