Pigmentary Lesions Removal


Removal of pigmentary lesions with the Medlite IV Laser System

Melanin is the substance that provides color to your skin. Either with fair or dark skin, we all have melanin in different quantities. Pigmentary lesions are dark simply due to the abnormal concentration of melanin in that skin area. The high concentration of melanin is due to different factors. Some types are present at birth, but most of them occur with the lapse of time or as a result of an excessive exposure to sun rays.

The laser removes pigmentary lesions through light energy. These beams are designed to produce one or more specific wavelengths that are absorbed by the pigment. Pigmentary lesions may be lightened or removed when the laser light passes through the skin to be absorbed by the abnormal concentrations of melanin. The quick absorption of light energy destroys the melanin to the point of reducing concentration, thus causing a uniform color and texture in the skin treated.

Medlite IV Q-Switched Yag Laser

It is one of the world’s most advanced instruments to remove pigmentary lesions. It produces appropriate wavelengths for a better laser beam absorption through abnormal melanin concentrations. Medlite IV laser emits rays of light through very short and high-density pulses for a maximum melanin destruction. The combination of a specific wavelength and the short pulses of rays of light produces a minimum aggression to the skin while achieving a maximum removal of abnormal melanin concentrations.

Which types of brown marks or pigmentary lesions does Medlite IV remove?

Medlite IV laser beam is generally recommended to remove age and liver marks, freckles and numerous brown birth marks. The physician will identify the specific lesion type and will analyze the average success of the removal.

IMPORTANT: the laser may not be used to remove cancerous or presumable cancerous lesions. In case of any doubt, your physician will inform you about the best procedure to be followed.

Why doesn’t Medlite IV laser take off the normal skin pigmentation as well?

The Medlite IV laser beam emits light in very small “flashes” called pulses. The impact caused by the energy of a powerful light pulse is similar to that produced by a thin band. After the treatment, the patient will feel a smooth sunburn sensation. Usually, after one or two days, any type of discomfort will disappear. The area may remain red for two to four weeks. Once it begins to lighten, it regains its natural color and soft texture.

How many sessions are required to remove a pigmentary lesion?

Almost 80% of all common pigmentary lesions are removed in only one session. Should the lesion cover a large area, the physician may decide to treat it in two stages to avoid unnecessary discomfort.

Can the excess of pigmentation return?

Normal pigmentation lesions are not recurrent. Some birth marks may return after a few months and up to one year. However, the treatment may be repeated with similar results.

Which kind of post-treatment care is required?

To begin with, an antiseptic cream will be applied to the treated area. The patient may take a bath on the day after, and he/she should avoid rubbing the affected area. Considering that most pigmentary lesions are caused by the exposure to solar ultraviolet rays, it is essential to use solar filters. Should this warning be disregarded, sun rays could damage the skin again, with the subsequent pigmentation lesions. The physician will recommend the solar filter level that is appropriate for your specific type of skin.
