Is the Q-switched laser freckle removal beauty instrument effective?
September 12, 2021

The effect is still relatively good.

1. Safety flat hat technology
The Q-switch laser uses the safety flat cap technology to output laser energy to ensure that the energy reaches the skin evenly, and there is no excessive heat scalding or uneven local heating of the skin.
2. Intelligent frequency doubling technology
The unique intelligent frequency doubling technology can automatically identify melanin of different depths, decompose pigment cells by double-layer gasification, and remove pigment spots across the dermis and epidermis at the same time.
3. Energy wrapping technology
The energy packaging technology of the Q-switched laser can package high-energy-density laser energy into clusters and act on the pigment cells in the dermis, so that it can release giant pulses in nanoseconds to blast the pigment cells. This energy wrapping technology greatly improves the treatment effect and shortens the treatment interval, from the original 28-day freckle-removing interval to a two-week interval.
4. Dual wavelength laser
The Q-switched laser has two laser wavelengths, 1064 and 532, which can be freely changed for treatment.
5. Intelligently adjust the spot size
The Q-switched laser has a good output spot pattern, the spot light intensity distribution is uniform, the size of the spot treatment head can be adjusted, and the band of the laser output energy can be adjusted to ensure that the laser output density remains unchanged.

Laser freckle removal is a laser device that produces a high-intensity beam, and different types of lasers can produce light of different colors. The eye color of the laser is the key to the treatment. Lasers of different colors are absorbed by the skin of different colors, and the laser energy is used to disintegrate and vaporize the dye particles to seal the blood vessels. When freckle is removed, as long as the frequency of freckle removal is selected according to your own situation, and the corresponding nursing work is done after the operation, generally speaking, there will be no recurrence.


Comprehensive judgment and treatment of facial pigmentation

Pigmentation refers to the unevenness and unevenness of facial tone caused by the local deepening of skin color. Its essence is the localized increase of pigment on the facial skin. The ultimate goal of pigmentation treatment is to make the complexion of the entire face look uniform. The diseases that cause pigmentation are different, and their treatment methods are completely different; in addition, the same patient often suffers from several different types of pigmentation, and the corresponding combination treatment should be carried out according to different symptoms. Therefore, the key to the treatment of pigmentation is correct diagnosis and appropriate treatment. There are 7 kinds of facial pigmentation common in plastic and cosmetic department: freckles, café au lait spots, inflammatory hyperpigmentation, age spots, chloasma, acquired nevus of Ota, and nevus of Ota.
1. Freckles (ephelis, ephelides, freckles)

Freckles are an autosomal dominant genetic disease. Most of the onset of freckles has been determined before birth. The symptoms are small yellow-brown spots on the face. The onset is in the school age, and the symptoms become obvious in adolescence, and turn into middle age. Not obvious. It is more common in women, and symptoms worsen during pregnancy, so it may be related to female hormones. The patient’s skin is mostly fair and dry. Freckles are often scattered on the cheeks, lower eyelid, and the root of the nose, and some patients involve the upper eyelid, forehead, nose, perioral, or even widely distributed on the entire face. Sun exposure can aggravate the symptoms of freckles, so freckles are more noticeable in summer, and people with freckles should use sunscreen in summer and on days with strong sunlight. The pigment changes of freckles are located in the epidermis, and the pathological manifestation is that the melanin in the basal layer of the epidermis increases, but the number of melanocytes does not increase significantly. The melanocytes in the lesion area are often larger, with more cell dendrites and hyperactivity.

Currently, the more effective treatments for freckles are intense pulsed light (photons) and Q-switched lasers. The photon treatment does not break the skin, so there is no need to take a vacation after the treatment, and since the treatment head is large, the entire face can be treated without any omission. The disadvantage is that the number of treatments is more, and it takes 3-5 treatments to achieve the effect of basic elimination. Q-switched laser (commonly used at 532nm, 755nm, 694nm) also has a very good effect on the treatment of freckles. Generally, it only takes 1-2 treatments to achieve the effect of complete removal. and recovery time, in addition, one-to-one treatment cannot be achieved for very small and illegible freckles. It is worth noting that most freckles will recur to varying degrees after treatment, and so far it is difficult to find a long-term cure.

2. Cafe au lait spots

Café-au-lait spots are an autosomal dominant hereditary disease. They are congenital coffee-stained spots on the skin surface. They vary in size and shape, with clear boundaries and uniform color, just like coffee with milk. The texture is completely normal and can appear on all parts of the face or body. These spots are not affected by UV exposure like freckles. A café-au-lait spot alone is just a birthmark and has no adverse health effects. If more lesions appear at the same time, it is necessary to pay attention to whether there is a “neurofibroma”. The pathological changes of café-au-lait spots are similar to those of freckles. They are also pigmented changes in the epidermis. The congenital local pigment cells are active, but the total number of local pigment cells does not increase.

Q-switched laser is the first choice for the treatment of café-au-lait spots. The commonly used wavelengths are 532nm (frequency-doubled Nd:YAG), 755nm (Alexandrite) and 694nm (ruby). The treatment is safe and does not cause scarring, but the effects vary greatly. Some patients can achieve obvious curative effect with one treatment, but the recurrence rate of some patients is beyond imagination. For some young children, if the Q-switched laser treatment cannot be performed due to pain, multiple treatments with intense pulsed light can be used, and certain effects can also be obtained.
