What is the difference between freckles freckles and melasma? Freckles are light brown or dark brown spots, small, scattered distribution and not fused, often onset in childhood, more common in adolescent females, obvious in summer, fade or disappear in winter. This kind of spots can be treated by Q-switched laser, which does not hurt the surrounding tissues and has positive efficacy. Melasma is mostly symmetrically distributed on the cheeks, yellowish, dark brown or dark coffee, with a patchy distribution, and the color shades are related to the season, sunlight and endocrine factors, sometimes also related to the patient’s rest and mental condition. This kind of spots usually need oral medication, and laser treatment is not effective. How do freckles occur? Freckles usually occur on the face, mainly on the bridge of the nose and cheeks, but also on the neck, back of the hands, chest and extremities. The rash is the size of a pinhead or a grain of rice, with light or dark brown round or oval spots, and is symmetrically distributed without fusing with each other, with a smooth surface. Patients usually have no conscious symptoms, and the rash is dark in summer and light in winter. The number of freckles increases with the age of the patient, and the color of freckles deepens after sun exposure, and excessive exposure to X-rays and ultraviolet rays can also promote and aggravate the disease. The color of freckles varies according to the amount of sunlight exposure, with a light brown color in winter and a dark brown color in summer. How can freckles be treated? There are many ways to treat freckles. At present, we mainly use multi-frequency Nd:YAG 532nm laser or photon treatment, which can penetrate to the pigment group in the basal layer of epidermis and dermis, so that it can be absorbed by pigment grains and make the pigment grains expand and rupture instantly and finally be eliminated from the body. The treatment process is safe, painless and does not affect study and work. What are the advantages of laser treatment for freckles? ①Strong selectivity: Although the number of freckle rashes is relatively large, most of them exist in isolation and do not fuse. By using laser treatment, we can avoid damage to normal skin to the maximum extent. ②Less times: Generally, after 1-2 laser treatments, freckles can achieve the effect of photon treatment. ③Less impact on skin function: Clinically, it is found that patients who have been treated by photon multiple times have lower tolerance to sunlight, cold and cosmetics, and are more likely to have capillary dilation and various dermatitis. This side effect can be avoided by using laser treatment. Why do age spots occur? Age spots are a kind of lipofuscin pigmentation on the skin of the face, hands, forearms and other parts of the elderly, which are caused by the oxidation of fat in the body due to the decrease of cell metabolism. It is generally irregular in shape, with clear boundaries with the surrounding tissues, and can be elevated or flush with the skin. There are many treatment methods for age spots, including laser, freezing and surgical removal. Freezing or surgery can leave more or less marks or scars, so the safe and effective laser has become the new favorite of clinical treatment. Eat more fresh vegetables and fruits, and reduce the fat content intake. Also pay attention to avoid long time strong sunlight exposure and abnormal stimulation, and use sunscreen appropriately, which will help the prevention and treatment of age spots. How to treat age spots with laser? Different lasers can be used depending on the manifestation of age spots. Age spots that are bulging, that is, bulging to the touch, can generally be treated with ultra-pulsed CO2 facial resurfacing. This method is somewhat destructive to the skin, but basically it can be healed and will leave no trace as long as the later care is strengthened. For age spots that are flush with the surrounding skin, we can use multi-frequency Nd:YAG 532nm laser to crush the pigment particles deposited in the epidermis and superficial layer of the dermis. How about the effect of laser spot removal? Laser cosmetic spot removal is the most popular spot removal surgery, laser cosmetic spot removal is not only effective, but also painless and will not leave scars, laser cosmetic is the best choice for women who love beauty to remove spots. Laser can treat freckles, age spots, sun spots, freckle-like nevus and so on. As to whether every patient can achieve satisfactory results after laser treatment, postoperative care is also very important. It is recommended to use physical sunscreen and not to touch water until the scab is removed. The majority of patients can achieve satisfactory results after a period of hyperpigmentation. In addition, individual difference is also a factor affecting the efficacy. If the patient’s skin color is whiter and the rash color is darker, and the contrast between the two is greater, the effect after laser treatment is very good. What is the process of laser blemish removal? Laser cosmetic spot removal is done by using a specific wavelength of light beam to act on the affected part of the skin, each beam produces a white skin of 0.2-0.3cm in diameter, and the pain is relatively mild. Since most of the sites of laser cosmetic blemish removal are located on the face, patients can choose a small piece of skin for trial first, and if the response is good, then do a large area of treatment. The treated skin is especially sensitive to sunlight and should be avoided. It is recommended to use physical sunscreen in order to achieve the best treatment effect. How long can freckles last after laser removal is characterized by dark rash in summer and lighter rash in winter. Generally, in order to avoid light and sunlight, we will advise patients to come to our department for treatment in winter, but with the strengthening of sunlight, the hidden freckles in winter will gradually appear, which gives us the illusion of freckle recurrence. Don’t be nervous at this time, just continue the treatment and knock off the revealed freckles in batches.
