How does an erbium laser work and where is it used in cosmetology?

In aesthetic medicine of the twenty-first century, many methods of rejuvenating and improving the condition of the skin are practiced. Unfortunately, not all of them are safe, often interference with the body’s natural processes is accompanied by the development of complications and the need for lengthy rehabilitation. If your skin is hypersensitive, an erbium laser can be a real salvation thanks to its delicate and targeted effect on problem areas.

Operating principle

An erbium laser has a thermomechanical effect on the epidermis, due to which the water bound inside the cells goes into a vapor state. Due to the increase in pressure inside the cells, pathological areas are destroyed and are “ejected” from the laser exposure zone.

High temperature evaporates the surface areas of the dermis, destroys dead cells and impurities, and contributes to the launch of internal recovery processes. Thanks to aggressive external influences, cells regenerate faster and fibroblasts intensively produce collagen and elastin fibers. Such a reaction is protective and is triggered by the body in order to recover from damage. Skin rehabilitation takes 1 — 2 weeks, regeneration processes last about 2 — 4 months, and the final result is evaluated precisely at their completion.

Advantages of the technique

Erbium laser in cosmetology is considered one of the most delicate methods of exposure. Due to its insignificant wavelength (2,94 μm), it has the ability of point penetration and does not affect adjacent soft tissues. Compared to other types of laser, erbium acts as gently as possible, penetrating to a depth of 5 microns, being completely absorbed in the tissues. This property allows you to control the effect on the skin and reduce the risks of possible complications.

It should also be noted that laser resurfacing of the skin using an erbium laser is tolerated by most patients quite easily, and often does not even require local anesthesia. The fact is that the treatment is carried out in areas that do not have nerve endings, and the insignificant thickness of the heated skin allows the temperature to quickly decrease without causing discomfort for a person. The delicacy of exposure allows you to work with the most sensitive areas of the skin located around the mouth or eyes.

The main difference of this procedure is the impact on the problem area not with one broad pulse of light, but with a beam, broken into separate fractions, with a diameter of not more than a millimeter. The goal of photothermolysis is the destruction of damaged cells and collagen, stimulating their replacement with new healthy fibers.

Indications

Erbium laser is indicated for patients of young and middle age. Its light energy is successfully used to eliminate the following skin defects:

  • Fine wrinkles on the face.
  • Stretch marks.
  • Traces of acne.
  • Dark spots.
  • Scarring.
  • Flabbiness and reduced tone of the skin of the face, neck, chest and hands.
  • Small benign lesions.
  • Vascular stars.

Among other things, the effect is used to reduce tattoos, increase skin elasticity, prevent ptosis and early withering of the skin, to improve complexion.

Contraindications

The use of an erbium laser is far from justified in all cases. Before carrying out the procedure based on it, the cosmetologist must make sure that the following contraindications are absent in the patient:

  • Oncology.
  • Diabetes.
  • Pregnancy.
  • Lactation period.
  • Dark skin color (natural shade or fresh tan).
  • Herpes, pustules and inflammation, skin diseases in the acute stage in the problem area, subject to laser exposure.
  • Varicose veins (if you plan to treat your legs).
  • Violation of blood clotting.
  • Mental disorders.
  • Autoimmune diseases.
  • Exacerbation of chronic pathologies and a pronounced course of bacterial or viral infections.

The laser is not used for increased skin sensitivity and for six months after taking medications containing retinoids.

Side effects and care after the procedure

Neglect of contraindications and a violation of safety during and after the procedure can provoke side effects and complications. A typical negative reaction of the body to an intervention of this kind is swelling, redness, discomfort, as well as mild burns, blisters. Less commonly, a skin rash resembling an allergic reaction appears.

The listed side effects are temporary and last for 4 — 8 days without treatment. However, it should be remembered that as a result of the procedure, more serious complications, scars, age spots may appear. To avoid trouble, be careful in the period after the procedure. Use drugs that accelerate tissue regeneration, do not sunbathe and do not go outside without applying ultraviolet light to the skin.

Erbium laser is used to rejuvenate the skin of the body and face, increase their elasticity, eliminate defects (scars and stretch marks), and reduce tattoos. It differs from other lasers by a short wavelength and the ability to completely absorb at a depth of up to 5 microns. It does not provoke pain during use, rarely causes side effects.
