Modern cosmetology actively uses a variety of devices and apparatuses to solve certain issues. Recently, in dermatocosmetology, laser technologies are increasingly being used, since they are not only highly effective, but also provide a quick and fairly long-lasting result.
What is a neodymium laser
Neodymium apparatus is a special device designed for use in dermatology and cosmetology and allows you to effectively solve various skin problems. It is referred to as solid-state laser emitters, which allows receiving waves of various lengths - from 532 nm to 1064 nm, depending on the application.
The active medium of a neodymium laser is a yttrium-aluminum garnet crystal activated by neodymium ions.
The use of such a radiator, according to experts, can significantly optimize various methods of skin rejuvenation, hair removal, removal of acne and post-acne, scars, tattoos.
Operating principle
The main difference between this type of laser and other similar devices is the penetration depth of 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 allows the use of neodymium lasers in cosmetology for the treatment of vascular pathologies and the elimination of their external manifestations.
The destruction of blood vessels leads to a 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 using neodymium lasers to remove tattoos, radiation affects the dye even in the deep layers of the skin, allowing you to remove pigment without violating the integrity of the skin.
Benefits of using
The best lasers are neodymium, as these are modern devices with compact sizes, convenient for the client and specialist, and a wide range of settings for various types of procedures.
Unlike other laser emitters, neodymium has special advantages that can be effectively used to solve cosmetic problems:
- He is able to deliver both short and long pulsed radiation, allowing the cosmetologist to develop an individual approach to each patient, depending on his problem and the features of the skin.
- Allows you to process the zone pointwise, which is especially effective when used to remove unwanted hair.
- It is equipped with a built-in cooling system to prevent skin heating during the procedure and thermal burns.
- It can be used on the skin of any phototype, including dark and tanned.
- Technical characteristics allow the most accurate control over the parameters of the radiation flux (energy density, length, frequency, number of pulses).
Hair Removal Application
Judging by the reviews, a neodymium laser is especially effective for removing unwanted hair on the face and body. A maximum laser length of 1064 nm is optimal for hair removal, as it effectively removes hairs with minimal side effects. The beam of such a laser penetrates the tissue to a depth of 8 mm, reaching the hair follicle, but the radiation is practically not absorbed by melanin. This feature of a neodymium laser allows hair removal regardless of the patient’s skin type.
A low degree of absorption creates the conditions for a complete and targeted delivery of radiation energy to the affected area — the hair follicle — without scattering and dangerous heating of surrounding tissues (controlled photothermolysis).
In this case, 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.
A neodymium laser allows you to eliminate not only dark, but also red and even light hairs, while other devices can not cope with this task.
Application for removal of blood vessels and rejuvenation
The property of a neodymium laser beam to coagulate and empty capillaries allows it to be successfully used in the removal of blood vessels in the presence of hemangiomas, spider veins and nets, and manifestations of rosacea. According to reviews, after several laser treatment sessions, the manifestations of such conditions disappear from the skin without a trace. In this case, even deeply located vascular formations, including large ones, can be removed due to the intense thermal effect on the affected area. At the treatment site after the procedure, there is a slight redness, which passes quickly enough.
A neodymium laser is also effective in treating acne and acne, as it affects the protein structure of bacteria, reducing the release of sebum and the likelihood of comedones. Existing inflammations under the influence of laser radiation ripen 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 is normalized, and the pores are narrowed.
In addition to solving cosmetic defects, a neodymium laser also allows you to rejuvenate your skin.
Laser resurfacing with such a device helps to normalize its color and improve blood circulation, and new young fibroblasts in which collagen and elastin are synthesized, which are responsible for skin elasticity, are actively growing in the treatment area.
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 folds and signs of aging.
Laser scar removal
Scars, especially in visible areas of the body and face, do not decorate anyone, and a neodymium laser helps to make them less noticeable, and in many cases completely eliminates them. When laser radiation is applied to scar tissue, vascular emptying and circulatory disturbance occur in the affected area. Nutrients stop flowing along with blood, fibroblasts die, and old collagen fibers are destroyed.
As a result of this effect, aseptic (non-infectious) inflammation occurs and the old destroyed scar tissue is replaced by fresh and full connective tissue, the development of a new capillary bed is stimulated. Modified collagen proteins are replaced by new forming elastin and collagen structures with an optimized arrangement.
This effect helps to tighten the tissues, enhance their turgor and elasticity, the scar fades and smoothes, and small scars dissolve completely. Traces after acne and acne are eliminated by a similar principle.
Neodymium Tattoo Removal Lasers
Often tattoos on the body are done in early youth and out of stupidity, and over time you want to get rid of them. For many years, the tattoo was removed by surgical excision, acids, cryodestruction, infrared coagulation, however, a significant drawback of such procedures was the formation of scars and depigmented areas in the area of the former tattoo.
A neodymium laser for tattoo removal is more effective, since it does not lead to trauma to the surface layer of the skin. Adjustable beam length allows you to remove both deep art tattoos and surface permanent makeup, which is especially important when it turned out unsuccessfully.
Under the influence of radiation, granules of a pigment or dye are destroyed, after which they are removed from the skin and body with the natural flow of lymph. Unfortunately, one session to completely remove the tattoo is not enough, especially with a large treatment area, however, with each subsequent session, the tattoo brightens and becomes less noticeable.
After the elimination of tattoos, no marks and scars remain on the skin, which is a significant advantage of the procedure over other methods.
Preparation and effectiveness of procedures
An important advantage of using a neodymium laser for cosmetic procedures is the lack of preparatory measures. At the consultation, a specialist examines the skin in the treatment area and can 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, as the described technique is absolutely not traumatic and does not cause serious external changes. In some cases, slight redness and swelling may occur after exposure to a neodymium laser, but they quickly pass. The effect of the procedure will be noticeable immediately and will gradually increase over several days.
Contraindications
Like any cosmetic manipulation, the technique using a neodymium laser has its contraindications. So, it is not worthwhile to eliminate skin defects and tattoos, as well as conduct anti-aging procedures:
- in acute or chronic inflammatory processes in the affected area;
- skin lesions or suspected malignant neoplasms;
- with herpes, psoriasis and eczema with rashes in the affected area.
- during pregnancy and breastfeeding;
- with bleeding disorders;
- mental disorders, especially epileptic;
- signs of fresh tanning (less than 7 days before the procedure).
Reviews
Reviews of the removal of hair on the body and face by a neodymium laser confirm that the effect of this procedure lasts much longer, in comparison with other methods of hair removal.
In the case of using this type of laser to treat acne and acne, as well as conditions of damaged skin, patients show good results after the first procedure. Passing the full course, according to them, makes the skin close to ideal.
When removing tattoos with a neodymium laser, in some cases the 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. Reviews of the neodymium laser claim that it will help return beauty and youth.
