In daily life, many women who love beauty like to go to beauty salons or on the streets to remove moles. In dermatology clinics, many patients will also encounter moles requesting removal. So, can "moles" be removed casually?

"Nevus" is medically called nevus cell or melanocytic nevus, which is a skin manifestation caused by an increase in melanocytes in the epidermis and dermis. If it is a rash that is higher than the skin surface, has a dome-like or nipple-like appearance, or has a peduncle, it is clinically called an intradermal nevus; those that are slightly higher than the skin surface are mostly mixed nevus; those that are not higher than the skin surface are junctional nevus .

As we all know, "mole" is a benign tumor that generally does not affect physical health. For cosmetic reasons, intradermal moles and mixed moles that are higher than the skin surface can receive laser or cryotherapy, and satisfactory results can be obtained. However, due to individual differences, some patients may leave slight scars after treatment; some people with specific physical constitutions may even develop keloids. This needs to be reminded.

Boundary moles that are no higher than the skin surface are sometimes difficult to remove with laser or freezing, and there are cases of recurrence. Special attention should be paid to the fact that most pigmented nevus growing on the palms, lipstick and vulva are junctional nevus. Junctional nevus in these areas that are often rubbed and pressured may become cancerous. Therefore, junctional nevus growing in these areas should be operated on. It should be completely removed to avoid future troubles. For junctional moles that grow on the face or other non-friction parts, there is generally no need to use drastic methods to harass them, such as laser, freezing, drug corrosion, etc., because repeated and inappropriate stimulation may also lead to cancer. .

If you want to use laser to remove tattoos, I can give you some suggestions:

Laser applications:

1. The most common tattoos and eyebrow tattoos

p>

Tattoos and eyebrow tattoos: Pigments are artificially implanted into the dermis, or pencil lead, iron powder, etc. are introduced into the skin due to accidental injuries. Generally, the problem can be solved with just a few laser treatments.

The 3045 Q-switched dual-wavelength medical laser beauty instrument outputs two wavelengths, 1064nm and 532 nm. The 1064nm Q-switched laser has strong penetrating power and can reach melanocytes or black and blue dye particles deep in the skin; The 532 nm Q-switched laser can be well absorbed by black and red pigments and can effectively remove black and red pigments. Achieve the purpose of completely removing pigment.

2. Laser treatment

The principle of laser treatment is that the laser instrument produces a high-intensity beam. Different types of lasers can produce different colors of light. The color of the laser is the key to treatment. Different colors of laser are absorbed by different colors of skin, and the laser energy is used to disintegrate and vaporize the dye particles, sealing blood vessels, and then the body absorbs the dye particles and eliminates them from the body, and the pigment disappears.

Because the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Only the diseased cells absorb the specific laser, while normal skin tissue is not damaged, so no scars will be left. Advanced laser technology can also control the skin depth that the laser reaches, and the adjustable pulse can minimize skin damage. Generally, the skin can return to normal within 7 to 10 days without affecting people's normal life. During the operation, the treatment time is only a few minutes at a time, no more than ten minutes at most. After each treatment, the skin must undergo a natural metabolism process of absorption, so the interval between treatments is generally 2 to 3 months. Depending on the size, number and depth of pigmented and vascular lesions, some treatments can achieve the desired effect in one or two treatments, but generally it takes 4 to 6 treatments to completely resolve the problem.

3. Characteristics of laser beauty treatment

1) It does not damage the skin or hair follicles, does not produce scars, and only removes pigment.

2) It can remove pigments that cannot be removed by drugs and other methods.

3) It is less painful and does not require anesthesia.

4) Recovery is fast and has little impact on normal work.

5) Cold light sterilization, no cross-infection, no special care required after surgery.

4. Preparation before laser treatment

1) There should be no inflammation in the treatment area.

2) Laser treatment is prohibited during menstruation and pregnancy.

3) Clean the treatment area, do deep cleaning if necessary, and then disinfect the treatment area.

4) Apply anesthetic to sensitive areas such as eyeliner and lips for 20 minutes before treatment. Shave and disinfect the affected area with hair.

5) Patients must take photos before laser treatment to facilitate comparison of the effects after laser treatment

5. Time and interval of laser treatment:

Pigment particles after laser treatment The subsidence and discharge time is generally about 3-6 months. Due to the different size, type, depth, and color of pigment granules in different pigmentary diseases, as well as individual differences in skin color, metabolic capacity, age, etc., the time and degree of fading and discharge of pigment granules after laser treatment are also different. The lighter the disease, the younger the patient, and the earlier the treatment, the better the effect. Generally speaking, superficial pigmented diseases such as freckles and sun spots require 1-2 treatments, wrong eyebrow tattoos require 3-4 treatments, and amateur tattoos require 4-6 treatments. Professional tattoos require 8-10 times, and deep pigmented diseases such as Ota nevus require 5-6 times, with an interval of 2-3 months between each time.

With laser treatment of spots, moles, etc., the skin will undergo a natural recovery process, just like normal pregnancy requires ten months of pregnancy before delivery. No one can overcome this.

After laser surgery, initially, the wound may be black and scorched. After 1-3 days, the wound may become slightly red, swollen and oozing (especially in the orbital area or wounds with large burn areas). A few may have blisters, and then become dry and inflamed. , 10 days to 2 weeks, the skin will fall off and heal. After healing, a small number of patients will have atrophic scars or hypertrophic scars. After healing from dye laser treatment, the skin surface may appear white, then rosy, or light brown. After 3-9 months, the pigment will gradually become closer to the skin color. The younger you are, the faster your skin will recover. Therefore, you must wait patiently after laser treatment and avoid being impatient or looking for trouble.

In principle, there is no need to scrub with water within two weeks of laser treatment. To keep the wound clean, some lubricating drugs can be used, and local antibiotic ointment can be used if necessary. It is forbidden to remove the scab early and let it fall off on its own. In addition, direct exposure to ultraviolet rays of the sun must be avoided. After treatment, some patients may have reddish skin and pigmentation. Depending on individual circumstances, the pigmentation will gradually subside after 1-6 months. 1-3 days after scar laser treatment, the treatment area and surrounding tissue will be red, swollen and have a small amount of exudate, and you may feel swelling and numbness. Afterwards, the redness and swelling gradually subsided, and the scabs healed in 1-2 weeks. Laser hair removal may be accompanied by a slight stinging or slight burning sensation. Most patients describe the feeling of being treated. Most patients describe the treatment as feeling like a rubber band snapping without the need for anesthesia to relieve pain. After treatment, the skin of the treated area may appear light red, as if it has been sunburned. Because laser treatment does not damage the skin, there is no need for bandaging and no special care.

Treatment Course Due to the complexity of various pigment problems, in order to protect normal skin, some pigments need to be treated in stages, such as nevus of Ota, chloasma and dermal spots, mixed color tattoos, etc., with an interval of 1 —Varies from 2 months.

6. Care after laser treatment

1) There may be slight pain during treatment, and there may also be temporary redness and swelling, which will disappear on its own.

2) The scab will fall off in 7-14 days and the wound will heal. Some patients may experience normal temporary pigmentation after surgery, which will be gradually absorbed. Oral vitamin C can reduce pigment reflux.

3) During the healing period, antibacterial ointment or oral anti-inflammatory drugs can be applied to prevent secondary infection. Avoid direct exposure to ultraviolet rays of the sun. Otherwise, temporary pigmentation will occur and scarring may occur after infection.

4) Before the scabs fall off, the treatment area should not be exposed to water, no makeup, no rubbing, and avoid spicy food, tobacco and alcohol. Do not eat dark-colored foods such as coffee, Pepsi, etc. in the near future. Let the scabs fall off on their own and do not peel them off by force. Do not participate in strenuous exercise to avoid infection caused by sweating.

5) After treatment of pigmented skin diseases, you must pay attention to sun protection. Pigment fading is a slow biological process, usually 1-3 months. During this period, you must continue to use sun protection. In order to obtain the best results, if repeated treatments are required, the interval should be more than 3 months.

6) Depending on the nature, pigmentation and location of the lesion, treatment for some diseases may require multiple treatments.

7) After treatment, if there are no special circumstances, you can come back for follow-up every 2-3 months. If infection or other conditions occur, please come to our center for follow-up in time.

It is advisable to raise the pillow when sleeping to reduce facial swelling (the treatment area is on the face). The treatment area is around the eyes. If the eyelids are swollen, you can apply ice to the affected area, or do forceful eyelid opening and closing movements to reduce the swelling. Do not use other drugs or cosmetics before the scabs on the treatment area fall off to avoid inflammation of the affected area. After the scabs fall off, you can wash your face normally. Areas that need to be recolored, such as eyebrows, can only be recolored after three months.

7. Precautions for treatment:

1) Pigment may disappear or lighten one or more times through laser treatment.

2) Laser treatment is performed on the superficial surface and generally does not cause scars.

3) Pigment changes may occur in the short term after laser treatment and will disappear after a few months.

4) Within two weeks of treatment, scrubbing is not advisable in principle.

5) Small area treatment only causes slight local swelling. When treating a large area, especially around the eyes, there will be significant swelling, which will disappear on its own after three to five days.

6) There may be mild redness, swelling, and light brown scabs after laser. Pay attention to wound protection and use some lubricating drugs for cleaning. It is forbidden to remove scabs early and allow them to fall off on their own.

7) A special facial mask treatment will be performed about half a month after the operation.

8) The treated area is sensitive to sunlight, so you should avoid sun exposure within three months after treatment. If necessary, use sunscreen lotion.

9) Try to avoid sun exposure for three weeks before treatment to avoid hindering the treatment effect.

10) Within one week before receiving laser treatment, you should avoid taking drugs such as aspirin to prevent easy bleeding.

In addition, there are two situations that require special attention:

① The patient has a scarring constitution and may leave unsightly scars. Be cautious when performing laser treatment. Once problems arise , go to your doctor for active treatment.

② If the patient's pigmentation spots are caused by endocrine factors, they may "reappear" after laser removal. Such patients need to combine other treatments, adjust endocrine disorders, use fading drugs, and take longer Take a large dose of vitamin C and eat more fruits every day.

After a period of time, most skin tissues can return to normal, superficial scars can heal, and pigment spots can fade. However, for some deeper and larger spots and moles, scars or pigmentation may remain after laser treatment. These are things that beauty lovers should carefully consider before undergoing laser treatment.
