With the continuous innovation of cosmetic technology and the continuous update of laser cosmetic equipment, advanced medical cosmetic laser equipment from various countries have now entered the Chinese cosmetic industry. Laser, photon, photon/intense light/IPL/OPT, RF, fractional laser, pixel laser, pixel RF and so on, even doctors are dazzled, beauty lovers will be more confused, right? For this laser beauty instrument selection and its adaptation to the symptoms of some confusion. The following is a detailed introduction with you. A, photon refers to the wavelength of 500-1200nm high-intensity pulsed light (i.e. intense pulsed light), because the thermal effect of its irradiation of the skin can stimulate collagen regeneration, to obtain the effect of wrinkle rejuvenation, which is commonly known as photorejuvenation. The most important thing is that it is not only the best way to get rid of wrinkles, but also the best way to get rid of them. DPL refers to the optimized intense pulsed light with wavelength of 500-600nm, which mainly targets facial redness and other vascular problems. 1.Mechanism: ①Destroy pigment, shrink blood vessels; ②Anti-inflammatory and sterilization, oil and lipid control; ③Increase epidermal thickness; ④Increase dermal thickness and elasticity. 2, the main treatment: ① acne-related problems: acne, acne marks, pore size, acne pits, acne scars, etc. ②Sensitivity-related problems: hormone-dependent dermatitis, seborrheic dermatitis, sensitive skin, etc. ③Vascular-related problems: various red spots (including post-laser red spots), red blood, spider nevus, etc. ④Pigmentation-related problems: uneven skin tone, freckles, post-inflammatory hyperpigmentation, chloasma, etc. ⑤Aging-related problems: fine lines, wrinkles, roughness, lack of luster, age spots, red blood, etc. 3. Advantages: ① easy to operate, slight pain, no need for anesthetic pain relief; ② no destruction of epidermis, skin care can be done on the same day of treatment under normal circumstances, without affecting daily life; ③ good at treating complex skin problems; ④ high safety, proper operation and care, almost no side effects; ⑤ can be done as a daily skin maintenance project for a long time. 4, cons: ① need multiple treatments, mostly more than 2 times to see the effect; ② although there are few side effects, but improper operation care or treatment timing is not appropriate, there will also be red spots, blisters, and even pigmentation (hypopigmentation), scars (rare), so photorejuvenation should not be too frequent, random, post-operative care to do a good job. The first thing you need to do is to get a good idea of what you are getting into. Radio frequency is a low side effects of skin photoaging treatment methods, and non-invasive, very safe. It gives electrical heating to the target tissues of the skin, but this electrical heating is completely controlled, and this controlled thermal damage to the skin can affect the structural changes of the skin, and also changes the length of collagen, and makes collagen regeneration. 1, the principle of radio frequency cosmetic positioning tissue heating, prompting the subcutaneous collagen contraction tightening, while the skin surface to take cooling measures, the dermis is heated while the epidermis to maintain the normal temperature, this time will produce two reactions: one is the skin dermis thickening, wrinkles followed by shallow or disappear; the second is the subcutaneous collagen form remodeling, the production of new collagen, the skin after a treatment to become more firm. 2, the main role ① improve wrinkles: forehead horizontal lines, frown lines, crow’s feet, nasal root horizontal lines, nasolabial folds, periorbital wrinkles, neck wrinkles, etc., especially for the forehead horizontal lines and periorbital wrinkles good effect. Stretch marks and other atrophy lines on the body can also be effectively eliminated. ② Skin tightening: RF beauty can be used for skin tightening after liposuction, etc., and effectively remove double chin. ③Thin muscle: used for muscle-type calf shaping, bite muscle hypertrophy thin face, etc. Three, laser laser is laser (laser), a specific wavelength of light in the spectrum, such as: dye laser is the wavelength of 595nm light, emerald laser is 755nm light. Laser is a monochromatic light with high energy, precise focus and certain penetrating power, which acts on human tissues and generates high heat locally to remove or destroy the target tissues. Various pulsed lasers with different wavelengths can treat various vascular skin diseases and pigmentation. Popular laser cosmetic surgery: (a) Laser mole “removal” refers to the removal of pigmented moles by laser cautery. At present, medical institutions with good conditions usually use pulsed carbon dioxide laser, especially when treating facial moles. 1.Mechanism: cauterize and destroy the mole cells. 2. Advantages: ① easy to operate, no need to bandage after treatment; ② safer and more effective than medicated mole spotting, with good controllability. 3.Disadvantages: ①There is slight pain during the treatment, sometimes numbing medicine is needed to relieve pain; ②It may recur, if it recurs, the laser can be used again, and if it recurs afterwards, it is not suitable for laser treatment again; ④The mole cells are completely burned by the laser, and the removed mole tissue cannot be sent for examination to determine whether the mole is malignant, as in the case of surgery, so laser “mole removal” is only suitable for Therefore, laser mole removal is only suitable for benign pigmented moles with no signs of malignancy (2) Laser spot removal refers to the destruction of pigment and/or pigment cells by strong pulsed light or laser to lighten and remove pigmentation. The specific treatment is more complicated and requires the in-person doctor to choose the appropriate instrument and parameters according to the type of spots. The commonly used ones are intense pulsed light, alexandrite laser, ruby laser, pixel (fractional) laser, skin purifying laser (such as C6, C10), etc. 1.Mechanism of action: destroy pigment and/or pigment cells. 2.Main treatment: freckles, chloasma, age spots, nevus of Ota, acquired nevus of Ota, coffee spots, etc. 3.Advantages: ① easy to operate, mild pain, most adults can tolerate; ② remarkable efficacy of freckles and age spots, laser can often remove them at once; ③ no damage to epidermis or only slightly damaged, simple and easy daily care, short recovery period; ④ proper operation and care, usually no scar (except scar treatment). 4. Disadvantages: ①Red spots, burning pain and other burn-like reactions will occur, especially when high energy and treatment area are large; ②In the early stage after treatment, the color of pigmentation will sometimes deepen and may last 1-3 months; ③Nevus of Ota and acquired nevus of Ota have remarkable efficacy, but the treatment period is long, so patience and persistence are needed; ④The causes of melasma are complex, and sometimes the treatment makes the pigmentation more obvious or the effect is not satisfactory, so special care is needed. It requires special care and caution, and the all-round cooperation of individuals is also very important; ⑤ The clearance rate of coffee spots is low, and individual differences are great. (3) Pulsed dye laser is a laser for vascular problems. The energy of this type of laser is easily absorbed by the hemoglobin in the blood vessels and is mainly used to treat skin vascular related problems. 1.Mechanism of action: destruction and contraction of blood vessels. 2.Main treatment: bright red nevus, red blood, spider nevus, rosacea, scars, etc. 3.Advantages: ① easy to operate, mild pain, most adults can tolerate; ② no damage to the epidermis or only slightly damaged, simple and easy daily care; ③ proper operation and care, generally do not leave scars (except for scar treatment). 4, disadvantages: ① there will be erythema, burning pain and other burn-like reactions, especially when the energy is high and the treatment area is large; ② there is purpura (blue-black treatment area) after treatment, which can last 1-3 weeks; ③ there will be pigmentation after purpura, which can last 1-6 months; ④ except for erythema and spider nevus which can be treated once, most others need more than 3 times. (iv) Fractional laser There are two types of fractional laser: exfoliative (i.e. vaporization) and non-exfoliative, which play a therapeutic role through the focal photothermal effect of laser. 1, the mechanism of action: ① peel off the epidermis, optimize the reconstruction of the epidermis (exfoliation type); ② stimulate the dermis, optimize the reconstruction of the dermis (exfoliation, non-exfoliation type). 2.Main treatment: ①All kinds of hyperplastic and atrophic scars, such as acne pits, acne scars, trauma scars; ②Aging-related problems, such as wrinkles, sagging, rough skin, uneven skin tone, etc.; ③Stretch marks, swelling lines, enlarged pores, blackheads, acne, pigmentation, etc. 3, Advantages: ① easy to operate, generally no scars after treatment; ② non-ablative laser does not destroy the epidermis, short recovery time (usually only 2-7 days). 4. Disadvantages: ① Pain is obvious during treatment, often need numbing medicine to relieve pain; ② There will be red spots, burning pain and other burn-like reactions, especially obvious when the energy is high and the area is large; ③ It can last for 2-6 months; ④ For safety reasons, it is often necessary to treat several times to obtain the desired effect through the cumulative effect. The difference between the three in wrinkle rejuvenation: 1, photon/intense light/IPL/OPT: remove spots, remove micro capillary dilation and stimulate collagen fiber regeneration, improve skin wrinkles and texture. 2, radio frequency: mainly stimulate collagen fiber regeneration, improve skin wrinkles and texture, depth and effect than photon. However, it is not effective for removing spots and microcapillary dilation. 3.Laser: Due to the difference of parameters such as wavelength and pulse width, different devices can remove spots, remove microcapillary dilation and stimulate collagen fiber regeneration, improve skin wrinkles and texture, but multiple laser devices are needed to match the treatment. Reminder: 1. All beauty modalities need to be decided by dermatological cosmetic physician interview. Choose a trustworthy and responsible professional physician interview, who will help you make the most suitable choice according to the instruments owned by this medical institution and its expertise, and it is not recommended to command the physician. 2, photoelectric beauty (including intense light, laser, radio frequency, sound waves, etc.) effect by a variety of factors, in addition to the doctor to help you choose the instrument, treatment timing and its parameter settings and other key factors, but also with your own skin metabolic force (including self-repair, waste removal, etc.), immunity, skin care, sleep, stress, diet and other multi-factor related. In addition, also with the instrument manufacturers, models, performance, etc., the same type of instrument, manufacturers or models are different, the beauty effect will be different, and sometimes even great differences; the same instrument, not timely maintenance, correction, will also affect the effect. 3, any beauty treatment, the effect is not necessarily permanent, especially for wrinkles, sagging, uneven skin tone, chloasma and other skin aging-related beauty treatment, because aging is an irresistible law of nature, beauty treatment is only to help you temporarily reverse and return to beauty, in order to maintain beauty, you need to repeat treatment regularly, but also need to eat well, sleep well, good mood!
