Modern cosmetology actively uses a variety of instruments and apparatus to solve certain issues. Recently, laser technologies have been increasingly used in dermatocosmetology, as they are not only highly effective, but also provide a quick and fairly long-lasting result.
What is a neodymium laser
The neodymium device is a special device designed for use in dermatology and cosmetology, which allows you to effectively solve various skin problems. It is classified as a solid-state laser emitter that allows you to receive waves of various wavelengths - from 532 nm to 1064 nm, depending on the purpose of the application.
The active medium of a neodymium laser is an yttrium aluminum garnet crystal activated with neodymium ions.
The use of such an emitter, according to experts, can significantly optimize various methods of skin rejuvenation, epilation, acne and post-acne removal, scars, tattoos.
Operation principle
BasicThe difference between this type of laser and other similar devices is the penetration depth of the radiation. Such a laser allows you to act not on the pigment or other skin structures, but directly on the vessels, coagulating and destroying them. It is this feature that makes it possible to use neodymium lasers in cosmetology for the treatment of vascular pathologies and the elimination of their external manifestations.
Destruction of blood vessels leads to lack of nutrition of skin formations, hemangiomas, acne and other dermatological and cosmetic defects and the gradual elimination of the latter. In the case of neodymium lasers for tattoo removal, the radiation affects the dye even in the deep layers of the skin, allowing the pigment to be removed without compromising the integrity of the skin.
Benefits of using
The best lasers are neodymium, as these are modern devices with compact dimensions, convenient for the client and the specialist, and a wide range of settings for various types of procedures.
Unlike other laser emitters, neodymium has special advantages that allow it to be effectively used to solve cosmetic problems:
- It is capable of delivering both short and long pulsed radiation, allowing the cosmetologist to develop an individual approach to each patient, depending on his problem and the characteristics of the skin.
- Allows you to treat areas pointwise, which is especially effective when used to remove unwanted hair.
- Equipped with a built-in cooling system to prevent skin heating during treatmentand thermal burns.
- Can be used on any skin phototype, including dark and tanned.
- Technical characteristics allow for the most accurate control over the parameters of the radiation flux (energy density, length, frequency, number of pulses).
Epilation application
To remove unwanted hair on the face and body neodymium laser, judging by the reviews, is particularly effective. The maximum laser radiation length of 1064 nm is optimal for epilation, as it effectively removes hairs with minimal side effects. The beam of such a laser penetrates into tissues to a depth of 8 mm, reaching the hair follicle, but the radiation is practically not absorbed by melanin. This feature of the neodymium laser allows hair removal regardless of the patient's skin phototype.
The low degree of absorption creates conditions for the complete and targeted delivery of radiation energy to the affected area - the hair follicle - without dispersion and dangerous heating of the surrounding tissues (controlled photothermolysis).
At the same time, the energy of the laser beam is easily absorbed by water, hemoglobin and oxyhemoglobin, transforming into a thermal effect that coagulates and destroys the capillaries that feed the hair follicles. As a result of the procedure, the follicles die within 5-7 days, and hair growth in the treatment area stops.
The neodymium laser allows you to eliminate not only dark, but also red and even light hairs, while other devices with this task do notcoping.
Application for vascular removal and rejuvenation
The property of the neodymium laser beam to coagulate and empty the capillaries allows it to be successfully used in the removal of blood vessels in the presence of hemangiomas, spider veins and nets, manifestations of rosacea. According to reviews, after several sessions of laser treatment, the manifestations of such conditions disappear from the skin without a trace. At the same time, even deeply located vascular formations, including those of large diameter, can be removed due to the intense thermal effect on the affected area. A slight redness remains at the treatment site after the procedure, which disappears fairly quickly.
Effective neodymium laser and in the treatment of acne and acne, as it affects the protein structure of bacteria, reducing the secretion of sebum and the likelihood of comedones. Already existing inflammations under the influence of laser radiation mature much faster, their resorption is significantly accelerated. After a course of procedures (8-10 sessions, depending on the severity of the problem), a new rash ceases to form, the degree of oily skin normalizes, pores narrow.
In addition to solving cosmetic defects, neodymium laser also allows you to rejuvenate the skin.
Laser resurfacing with such a device helps to normalize its color and improve blood circulation, and new young fibroblasts begin to actively grow in the treatment area, in which collagen and elastin are synthesized, which are responsible for elasticityleather.
The formation of structures with elongated and filled fibers creates a lifting effect and leads to the complete elimination of fine wrinkles and a significant reduction in the severity of deeper wrinkles and signs of aging.
Laser scar removal
Scars, especially on visible areas of the body and face, do not adorn anyone, and the neodymium laser helps to make them less noticeable, and in many cases completely eliminates them. When exposed to laser radiation on scar tissue, vessels are emptied and blood circulation is disturbed in the affected area. Nutrients stop flowing with the blood, fibroblasts die, and old collagen fibers are destroyed.
As a result of such exposure, aseptic (non-infectious) inflammation occurs and the old destroyed scar tissue is replaced by fresh and complete connective tissue, the development of a new capillary bed is stimulated. Altered collagen proteins are replaced by new nascent elastin and collagen structures with optimized alignment.
This effect helps to tighten tissues, increase their turgor and elasticity, the scar turns pale and smoothes, and small scars dissolve completely. According to a similar principle, traces after acne and acne are also eliminated.
Neodymium lasers for tattoo removal
Often tattoos on the body are made in early youth and stupidity, and eventually you want to get rid of them. For many years, tattoos were removed by surgical excision, acids, cryodestruction, infrared coagulation, but a significant drawback of such procedures was the formation of scars and depigmented areas in the area of the former tattoo.
Neodymium laser for tattoo removal is more effective, as it does not cause trauma to the surface layer of the skin. The adjustable beam length allows you to remove both deep artistic tattoos and superficial permanent makeup, which is especially important when it turned out unsuccessfully.
Under the influence of radiation, pigment or dye granules are destroyed, after which they are removed from the skin and body with the natural flow of lymph. Unfortunately, one session is not enough to completely remove the tattoo, especially with a large treatment area, however, with each subsequent session, the tattoo brightens and becomes less noticeable.
After the elimination of tattoos, no traces or scars remain on the skin, which is a significant advantage of the procedure over other methods.
Preparation and efficiency of procedures
An important advantage of using a neodymium laser for cosmetic procedures is the lack of preparatory measures. During the consultation, the specialist examines the skin in the treatment area and may prescribe additional manipulations before the procedure only in case of an inflammatory process, herpetic eruptions or similar problems.
Immediately after laser treatment, you can go home, since the described technique is absolutely not traumatic and does not cause serious externalchanges. In some cases, after exposure to a neodymium laser, slight redness and swelling may be observed, but they quickly pass. The effect of the procedure will be noticeable immediately and will gradually increase over several days.
Contraindications for use
Like any cosmetic manipulation, the technique using a neodymium laser has its contraindications. So, it is not worth eliminating skin defects and tattoos, as well as carrying out anti-aging procedures:
- for acute or chronic inflammatory processes in the affected area;
- skin lesions or suspected malignancy;
- for herpes, psoriasis and eczema with rashes in the affected area.
- during pregnancy and breastfeeding;
- for bleeding disorders;
- mental disorders, especially epileptic;
- signs of a fresh tan (less than 7 days before treatment).
Reviews
Reviews of neodymium laser hair removal on the body and face confirm that the effect of this procedure lasts much longer compared to other hair removal methods.
In the case of using this type of laser for the treatment of acne and acne, as well as conditions of damaged skin, patients report good results after the first procedure. The passage of the full course, according to them, makes the skin close to ideal.
When removing neodymium laser tattoos in some casesthe process can take up to six months, but in general, the method provides good results without undesirable consequences.
In general, the laser is a modern and effective device that allows you to solve many cosmetic and dermatological problems. Its use in aesthetic medicine and cosmetology helps in many cases to avoid surgical intervention. Neodymium laser reviews claim that it will help restore beauty and youth.
