Laser against skin hyperpigmentation

Prior to the active introduction of laser technologies in cosmetology, the removal of excessive skin pigmentation was ineffective. Specialized creams and masks often could not provide the desired result in a relatively short period of time. In addition, the use of various gels and masks is fraught with the appearance of side effects, as they all have an impressive list of contraindications. Very often, the use of gels against causes severe allergic reactions, atrophy of the skin due to aggressive effects, acne-like rashes and dermatitis. Therefore, the high likelihood of complications and the inability to achieve the removal of hyperpigmentation (in the best case, lightening by several tones), leads to the fact that the use of creams and ointments for these purposes is becoming less and less popular. That is why laser technologies in cosmetology are so popular and in demand at present, because When using high-quality laser device, the result will be guaranteed and durable.

What is hyperpigmentation

Hyperpigmentation of the skin is a phenomenon associated with the uneven distribution of melanin (formed from the tyrosine amino acid under the influence of the tyrosinase enzyme) in human skin. In the absence of violations of skin pigmentation, melanin absorbs ultraviolet light and protects against the harmful effects of ultraviolet and infrared radiation. Thus, the skin is protected from burns and / or overheating. Most often, areas of the skin with a violation of the normal level of melanin are darker or lighter than healthy areas of the skin.

What types of hyperpigmentation are distinguished

Today there is a fairly stable classification of types of hyperpigmentation of the skin. Beauticians distinguish several main groups of hyperpigmentation:

1. Congenital (due to genetics). These include freckles, nevi, birthmarks.
2. Acquired (due to external factors). This group includes lentigo, melasma, post-inflammatory pigmentation, chloasm

Causes of skin hyperpigmentation

The most common causes of hyperpigmentation of the skin include the following factors:

1. Hereditary predisposition.
2. Hormonal disorders in the body.
3. Violation of the rules for skin care after some procedures.
4. Taking medications with a photosensitizing effect (increased sensitivity of the skin to sunlight).
5. Frequent and severe stress.
6. Excessive exposure to the sun (in a solarium).
7. Contact with pesticides.
8. Some diseases of the internal organs, etc.

The principle of laser treatment for hyperpigmentation of the skin

A directed laser beam penetrates the skin and is actively absorbed by melanin. As a result, melanin is heated and destroyed. The skin turns red, a protective crust appears on the area affected by the laser, which peels off in a few days.

Why is it worth choosing a laser to treat hyperpigmentation

To date, the laser method of treating hyperpigmentation is the most common and effective. Highlight the following advantages of using a laser:

1. The ability to vary the intensity and duration of the pulses.
2. Complete absence of scars or serious injuries after the procedure.
3. Lack of recovery period. After the procedure, the patient can live a normal life, only observing some post-procedural recommendations.
4. Ability to treat absolutely any area of the skin.

Contraindications for laser treatment of hyperpigmentation

Despite the large list of benefits, this procedure is not shown to everyone, taking into account the following factors:

1. Prolonged exposure to the sun less than a month before the procedure.
2. The acute stage of a chronic disease.
3. Pregnancy and lactation.
4. Taking photosensitizing drugs.
5. Diabetes.
6. A predisposition to the formation of keloid scars.

Stages of the procedure

As with any cosmetic procedure, in this case, the following stages of laser treatment of hyperpigmentation exist:

1. Before the procedure: abandon the solarium, prolonged exposure to the sun, use of sunscreen (about 1 month before the procedure).
2. Consultation with a specialist (determination of phototype and skin sensitivity, laser selection).
3. Procedure (from 15 to 60 minutes – depending on the size of the affected area): laser hyperpigmentation treatment.
4. Recovery period (several days): follow the doctor’s recommendations for skin care.

In some cases, the procedure should be repeated several times to achieve maximum effect.

What laser can cure hyperpigmentation of the skin

Today, it is possible to use several lasers to treat hyperpigmentation. Moreover, all of them must work in Q-Switch mode due to the very short times of VTR (thermal relaxation time) of melanin particles. The use of anti-pigment lasers in the free-running mode will lead to tissue overheating and complications.

1. Alexandrite in Q-Switch mode (wavelength – 755 nm) – heats and destroys melanin.
2. Nd: YAG KTP Q-switched laser (wavelength – 532 nm).
3. Ruby Q-Switch laser (wavelength – 694 nm).

Despite the huge number of systems that allow you to deal with pigments, it is preferable to choose a medical laser system LASEST. This system allows you to remove any pigment from the skin in a quality and painless manner thanks to the presence of all the above modules and finding the most effective solutions for each laser.
