Laser cosmetology is an important part of modern cosmetic medicine, and the effective treatment of some cosmetically impaired diseases benefits from the progress and development of cosmetic laser medicine, such as some of the untreatable nevus of Ota in the past and vascular lesions and tattoos with limited therapeutic effect, etc., which can now be treated and is a cosmetic treatment of the real sense. What is more gratifying is that laser cosmetology can let beauty lovers fully display youth, retain youth, let beauty and life together. 2.What kind of skin diseases can be solved by laser cosmetic treatment? A, red lesions – skin vascular disease treatment: including bright red nevus, hemangioma, all kinds of capillary expansion, spider nevus and so on. Selectable lasers: 595nm, 585nm, pulsed dye laser, long pulse width 1064nm gentleYAG laser, adjustable pulse width 532nm laser, frequency-multiplied Nd:YAG laser, etc. Therapeutic principle: when specific wavelength laser acts on blood vessels, the energy is absorbed by oxygen and hemoglobin in the blood, hemoglobin coagulates to form thrombus, and at the same time the endothelial cells of blood vessels are damaged, resulting in the blockage of blood vessels. B. Black lesion-pigmentation increase disease: nevus of Ota, Ito nevus, brownish green nevus, freckle. Freckle-like nevus, moles, seborrheic keratosis, coffee spot, chloasma, pigmentation and tattoo. Optional lasers: Q-switched ruby laser, Q-switched Nd:YAG laser, Q-switched emerald green, intense pulsed light, etc. Treatment principle: the melanin particles of the lesion tissue selectively absorbs the specific wavelength laser, the pigment particles are burst, the neighboring normal tissues are not destroyed, and this pigment particles debris is phagocytosed by the macrophage cells through the metabolism and discharged from the body. C, white lesions – pigment loss disease: vitiligo, halo nevus, etc.. Optional lasers: narrow-wave UVB, high-energy ultraviolet light, 308nm excimer laser and so on. Treatment principle: UVB can inhibit the activation of T cells to reduce the destruction of melanocytes, stimulate the proliferation of melanocytes, migration, synthesis of melanin and melanosomes into the epidermal cells, with the cellular keratinization metabolism and discharge. 3, there is no skin disease, just want to be more beautiful, what can be done with laser? For more extensive beauty, the new laser technology can, icing on the cake.

Laser treatment is only a means of treatment, there are both advantages and defects, there may still be some complications during and after the operation, and the course of treatment is long, most of them need several times of treatment, and the cost is high, need to be objective evaluation and understanding of the patient or the seeker. Before the treatment, you need to sign an agreement and keep photos for your files. Common side effects include pain during treatment, fear of treatment, post-operative erythema, swelling and even blisters, skin tightness and dryness, hyperpigmentation, hypopigmentation, scar formation, capillary dilatation, skin sensitivity, and reduced barrier function. Some side effects can be relieved after symptomatic treatment, and there are some side effects that are difficult to subside. 5.Can laser bring 100% perfect effect? Often people ask, after the treatment can be as white as a certain person? In fact, the effect of whitening is relative. Laser achieves whitening effect by acting on melanin, and our skin color is related to heredity, and the skin type will not change. 6.The price of photorejuvenation in different laser centers varies, how to choose? In the current era of rapid development of laser technology, laser equipment of mixed quality, laser treatment practitioners also have high and low technical level, different quality of service, resulting in differences in the price of treatment, for example, some people in the beauty salon to do photon, the whole face only received a dozen or so light spot irradiation, the price is only a few hundred dollars, and in the formal medical place at least to do four or fifty light spots, the price is also higher, the two treatment The effect of the two treatments is definitely different. And any laser treatment has a course of treatment, photorejuvenation treatment for each course of 5-6 times, if the endless package of annual treatment is bound to lead to a number of side effects, causing irreparable losses to the patient. Therefore, we can not simply compare the price, it is recommended to choose the regular medical institutions for cosmetic treatment.
