Eight association-certified dermatologists with more than 10 years of experience using 1550nm and 1927nm laser systems completed an online clinical survey on dual-wavelength skin laser treatment systems to share their clinical experience. After discussion, the 1550nm and 1927nm dual wavelength laser systems can be widely used in the fields of beauty and skin treatment.
Non-ablative fractional lasers (NFLs) for facial rejuvenation are mid-infrared lasers with water as a chromophore and wavelengths ranging from 1320nm to 1940nm. Fractional laser treatment produces a series of thermally damaged microscopic treatment zones (MTZ) on the skin, thereby inducing a wound repair response in the dermis without damaging the epidermis.
1550nm erbium lasers are suitable for cosmetic procedures requiring soft tissue coagulation and skin rejuvenation, and can also be used to treat epidermal lesions such as freckles and actinic keratoses [AK], pigmentary abnormalities (such as melasma), periorbital wrinkles, acne scars, and surgical scars. The 1927nm thulium laser is suitable for dermatological surgeries that require soft tissue coagulation and for the treatment of AK and pigmentary abnormalities.
1550nm/1927nm dual wavelength non-ablative fractional laser.
1550 nm & 1927 nm dual wavelength non-ablative fractional laser, the heat energy of the laser pulse triggers collagen coagulation (not vaporization), which is safe and effective. The treatment process keeps the stratum corneum structure intact, and thousands of micro-wounds are surrounded by healthy tissue growth, which accelerates healing and shortens the recovery period and downtime. The treatment is equipped with a synchronous cooling system to reduce pain and improve comfort during treatment.
1550 nm and 1927 nm dual wavelength equipment: 1550nm is good at deep skin problems, 1927nm is good at superficial skin pigmentation problems, deep and shallow synergy, full-layer effect, comprehensive treatment for skin problems at different levels, so as to achieve the effect of skin tissue reconstruction and anti-aging.
1550 nm Erbium laser non-ablative fractional machine.
The 1550nm erbium laser non-ablative fractional treatment system combines the characteristics of deep penetration, strong thermal stimulation, less damage, relative mildness, few side effects and rapid recovery of non-gasified fractional lasers, creating the gold standard for non-ablative treatments such as skin rejuvenation, wrinkle removal, scar repair and stretch mark repair. Once the product came out, it received widespread attention from medical cosmetologists at home and abroad and was hailed as the gold standard technology for non-surgical beauty.
At present, most of the laser technologies used in domestic hospitals are ablative lasers, which will cause certain damage to the skin. For example, fractional ablative lasers, pixel lasers, etc., use the gas-heat effect to peel off the epidermal tissue, vaporize it, and then enter the dermis to activate collagen regeneration. Because its heat stays more in the epidermis, it decreases rapidly downwards. In order to allow more heat to enter the dermis, it will peel off the epidermis as much as possible.
Compared with the previous carbon dioxide laser, pixel laser, and fractional laser, the 1550nm erbium laser non-ablative fractional laser treatment system uses non-ablative technology, which is less irritating to the skin, less traumatic, and less painful than other lasers in treating skin problems. It is easier for patients to adhere to the treatment, and the risk of pigmentation after treatment is very low. Each treatment of the 1550nm erbium laser non-ablative fractional laser treatment system takes about tens of minutes, and the treatment does not affect normal study and work. Compared with traditional lasers, it greatly shortens the treatment course and the time to see results.
Fractional 1927 nm Thulium laser non-ablative machine.
1927nm fractional thulium laser is a long-pulse infrared laser. It uses selective photothermal effect to act on melanin, water molecules, and hemoglobin in the skin. The skin absorbs laser energy and produces a thermal effect, which causes the melanin particles to heat up and inactivate; it stimulates the skin to start the regeneration and repair mechanism, stimulates the proliferation of collagen fibers, and stimulates the skin to produce more hyaluronic acid, thereby playing a role in mesodermal care, whitening and lightening, lifting and wrinkle removal, oil control and acne removal and other beauty effects.
The skin thermal effect will have a slight epidermal micro-exfoliation (which can be controlled with energy), which can continuously stimulate collagen hyperplasia for 1-2 months; there is almost no downtime, and the interval between the project and treatment is short, which is easier to accept.
Full face treatment: It can treat the upper and lower eyelids, smooth crow’s feet, and tighten and lift the upper eyelids. The effect is obvious. Because it belongs to the range of non-exfoliation-micro-exfoliation, the repair is relatively simple.
The 1927nm treatment handle has a unique feature, which is that it forms micropores on the skin surface and opens the skin channel. Each micropore is an independent three-dimensional structure, which can act as a container and continuously transmit the function.
These micropores are left by the vaporization of water after the photothermal effect, so after the 1927nm laser treatment, it is best to apply a layer of essence or water light product in time to fill the micropores and allow the essence to penetrate deeper into the skin faster. After the epidermal melanin is crushed, these melanin are also metabolized through the micropores.
Why is melasma so difficult to cure?
The essence of melasma is actually acquired pigmentation. Its cure is a difficult problem in medicine. There are three main reasons for this:
The causes are complex.
Sun exposure, sex hormones, endocrine, systemic diseases, emotions, dermatitis, aging, lack of sleep, genetic factors, improper skin care, etc. may all lead to the formation of melasma.
Melanin is complex.
Abnormal melanin is the cause of melasma. The melanin of melasma is distributed in different skin tissue layers, which makes the treatment very complicated.
Unpredictable.
The causes of melasma are very complex. Even if the treatment achieves a certain effect of lightening the spots, new melasma may occur due to certain factors.
Dual wavelength laser treatment for melasma.
Due to the principle of fractional laser, non-ablative laser, 1927 thulium laser and 1550 erbium laser may be more suitable for mixed melasma, melasma with limited skin lesions and surrounded by normal unaffected skin. In general, non-ablative fractional laser treatment of melasma has less risk, better effect and fewer adverse reactions than ablative fractional laser treatment, but when using it, attention should still be paid to the individualized setting of parameters such as dose, spot coverage, number of treatments, and treatment cycle, so as to achieve better clinical efficacy.
Fractional lasers use the principle of focal photothermal action to generate array-like tiny beams of light that act on the skin, forming multiple micro-treatment areas with columnar structures, without damaging surrounding tissues. Fractional 1550 and 1927 nm dual-wavelength lasers have been shown to have a certain effect in the treatment of melasma.
Treatment principle.
The generated micro-laser beam can also directly act on the melanocytes, melanin granules and keratinocytes in the chloasma lesion area, causing the target tissue to produce photothermal effects and necrosis and disintegration.
The columnar necrotic tissue is replaced by the surrounding regenerative tissue, so that the skin heals quickly, and the new tissue replaces the damaged tissue to achieve dermal collagen reorganization and proliferation.
Treatment plan.
1927nm thulium laser and 1550nm erbium laser combined with tranexamic acid
The specific wavelengths of 1927 and 1550 nm thulium lasers can accurately hit the melasma patches, breaking them into pigment particles and then excreting them with metabolism;
At the same time, oral tranexamic acid and external application of tranexamic acid essence can resist inflammation, repair the barrier, relieve dryness after laser surgery, reduce the activity of melanocytes caused by free radicals, and reduce the production of melanin.
How to prevent melasma from recurring?
There are many factors causing chloasma. To prevent the recurrence of chloasma, we need to start with the common factors.
Repair the skin barrier in time.
Melasma is usually accompanied by impaired skin barrier function. If the damaged skin barrier is not repaired in time after the treatment of melasma, it will induce new melasma. Therefore, after laser treatment of melasma, you must strictly follow the doctor’s advice and carefully perform barrier repairs such as moisturizing and sun protection.
Do daily skin care and sun protection.
Ultraviolet radiation can induce inflammatory reactions, lead to the accumulation of free radicals, damage the skin barrier, and directly stimulate the synthesis and transportation of melanin, so sun protection is very important to prevent the occurrence of chloasma.
Have a healthy lifestyle.
Unhealthy lifestyles such as smoking, drinking, staying up late, and stress are detrimental to physical health and skin beauty. Studies have shown that these factors can induce skin barrier damage and abnormal melanin synthesis.
