Freckle

Freckle is an inheritable skin defect. Usually symptoms are shown in the young age, the rash is round, oval and irregular brown pigment concentration. It’s usually under 0.5cm, around the size of a needlepoint or a granule of rice, distributed as points, the number varies. It’s most frequently shown on the face, especially on the nose and the cheeks, sometimes also seen on other body parts, but not shown on any unexposed region. The exposure to sunlight is a necessary factor for the occurrence of rash. Freckles impair a person’s appearance, but it does not yield a subject feeling or any other influence. For the treatment, other than reducing the over-exposure to sunlight, the traditional method of chemical shedding is also applied.

With the advancement of modern medical technology, some new techniques also evolve and are applied in the treatment of the freckles, and the photon method and laser method are the most frequently used techniques. The photon method is to apply wave of wavelength between 560 and 1200nm in the treatment , with interval of 3 months between treatments, one treatment course consists of 3-5 treatments. Compared to the traditional method, photon method has an edge in improving the general condition of the facial skin, but the method also has its defects.



Shanghai ConBlo Plastic and Laser Surgery utilizes the MEDLITE quadruple wavelength laser treatment device, which is the most advanced in the U.S.A., to treat many cases of freckle patient, from many years of clinical observation, not only the results are effective, the side-effect is also very small, it is mainly shown in the following aspects:

1) the range of choice is wide: although normally the number of freckles and rashes are large, they are isolated, not combined. Applying the laser treatment can avoid the impairment on the normal skin to the maximum extent

2) less frequency of treatment: normally after 1-2 laser treatments for the freckles, we can achieve the same result which requires much more times of photon treatment.

3) It has less impairment on the skin function: clinical observation shows that after many times of photon treatment, the patients’ skin is less endurable to the sunlight, coldness and cosmetics, and easier occurrences of the expansion of the blood capillary and the dermatitis are seen, however, using the laser treatment can avoid this side-effect.

But for the laser treatment for the freckles, whether every patient can achieve a satisfactory result also depends on the after-treatment care and maintenance. Usually after treatment, patient has to avoid sunlight, the scab part has to be kept away from water before shedding. Most of the patients can achieve a satisfactory result after a period of pigment precipitation. Besides, the difference between individuals also affects the result of treatment. If the patient has whiter skin, darker rashes, that means the contrast between the two is significant, the result of the laser treatment will be very good.
