the laser affects the skin affected by acne
The laser radiation is directed at the individual affected skin, thus it is very important, it does not hurt healthy tissue. At the same time laser treatment reduces the activity of the sebaceous glands, promotes rapid healing of wounds, improve blood circulation, normalization of sebum production.
In patients with acne, doctors put three tasks:
achieve complete clinical cure (disappearance of all the elements of acne);
prevent scarring (post-acne), or to improve the condition of existing scars;
develop an individual set of preventive measures to prevent the development of acne in the future.
In the struggle with inflammatory components used method of non-ablative effect on the bacterial flora of acne foci, based on the effect of a homogeneous photothermolysis provided by long-pulse Nd: YAG laser. The parameters of laser action:
pulse duration - 50-100-200 ms;
energy density - 15-50 J / cm2;
diameter of the spot - 4-6 mm.
The methodology used for the treatment of all forms of acne at any stage of development elements. It is based on the absorption of protein shell microflora wavelength of 1064 nm with the occurrence bacteriolysis effect; It is used both independently and in the treatment of acne. During the procedure used aiming handpiece to work on single items and the scanner S-II for the whole of the affected area in severe cases. The emission of a long Nd: YAG 100 laser beams is directed to sterilization of foci of acne. We must remember that laser treatment is not compatible with the use of medications that increase photosensitivity.
The choice of the 100 laser beams depends primarily on the stage of the disease:
Stage 1 - sufficient use of Nd: YAG laser, 1-2 treatments per week, course of 8-10 (number of passes - 1-2);
Stage 2 - the first place is the use of Nd: YAG laser, but the tactics vary: 3-4 procedures daily (number of passages 1-2), then a break in treatment for 3-5 days, followed by a second course of 8-12 procedures and after 2-4 weeks of use joins erbium or CO2 laser;
3rd stage - the first long-term treatment of papules, pustular rash course of 10-12 treatments: daily sessions, or with an interval of 3-7 days, which is determined by the physician as the patient's skin recovery (number of passages 3-4), and then resurfacing.
From the above it becomes clear that in the treatment of acne, regardless of the first stage is the type of laser applied combating inflammatory elements and then joined skin resurfacing. In men, skin is more dense than women, so they are used and higher parameters of laser exposure.
The basis is the use of laser resurfacing a laser beam, which penetrates into the surface layers of the skin (1-20 microns) and evaporation provides cells. Eliminates the old layers of the epidermis, the skin is regenerated, its complete update: subjected to laser exposure collagen fibers stimulate the emergence of new fibroblast cells, which in turn synthesize new fibers.
The following types of 100 laser beams are used to treat acne: neodymium, erbium, karbondioksidny (CO2), as well as factional. The radiation energy erbium laser is concentrated in a thin layer of the skin to a depth of about 1 micron radiation karbondioksidnogo laser penetrates deeper - up to 20 microns. The main effect in the first case is the evaporation cells is called second additional tissue coagulation. Given these differences in action karbondioksidny laser is used, if they want to achieve the maximum effect of skin renewal and aligns its relief, which, however, is associated with a higher risk of complications. Erbium laser has a "cautious".
In turn, the skin is heated fractional laser treatment zone is not in the entire area, and microfractions forming a coagulative necrosis area of about 0.2 mm and a depth of 1.5 mm. The heating in the epidermis and coagulation occurs in the lower layers, the stratum corneum of the epidermis is not substantially damaged. "Columns" of coagulation necrosis surrounded by burn shock zone. The final 1-3 hours after exposure to the laser emission takes place of heat shock proteins, growth factors, interleukins, processes that trigger proliferation in the epidermis and dermis, and activate intra- and extracellular proteolysis damage zone attract immune cells, primarily macrophages. Due to migration and division of the stem cells of the epidermis basal layer in the area affected is fully restored in 24 hours.
Do not forget that the use of laser karbondioksidnogo requires anesthesia, using erbium and fractional laser need only surface anesthesia, but with a neodymium laser procedure is almost painless and does not require any anesthesia. Selection of the type of laser depends on the flow of procedure of acne in an individual patient. Taken into account the amount of intervention required and the duration of the recovery period.
The advantages of laser acne treatment
The use of laser for all possible forms of acne, at any stage of its development: not only can clean the skin from pathogenic microorganisms, but also to relieve the patient from seals, inflammation and swelling of the skin. Moreover, it is laser therapy can restore metabolic processes in the skin, stimulate the synthesis of new cells and exfoliate dead skin.
Another advantage of laser treatment is that it provides stable, long-term remission of the acne manifestations and does not lead to addiction.
Laser can be used at any location eruptions of acne, the latter does not affect the choice of laser technique parameters.
Subject to the doctor's recommendations laser acne treatment can be performed at any time of the year. And this is very important, because often many patients exacerbation of acne are seasonal in nature: in the autumn-winter period of their provokes cold, summer - heat and UV radiation.
In most cases, laser treatment does not cause complications, exceptions are cases in which the wrong diagnosis or the patient fell into the hands of unqualified doctor has been put.
The energy released by the laser acts gentle way, so after the procedure does not remain scars.
With laser therapy appointment you need to keep in mind the contraindications and limitations, with which are:
diabetes in decompensation stage;
reception retinoids (synthetic drugs vitamin A) in the last 6 months; antibiotics tetracycline group or other medicines that increase the skin's sensitivity to light during the past month;
unusual skin formation and age spots, rashes non-inflammatory origin, overgrown scars in the areas of application of the treatment;
all types of herpesvirus, chronic dermatoses with impaired integrity of the skin (eczema, psoriasis, etc.) in the application of the treatment;
perform during the last 2 weeks of deep chemical or mechanical skin resurfacing (peeling) in the areas of intended use of the laser;
holding during the last 3 months of laser correction of wrinkles or laser skin rejuvenation in the areas of intended use of the laser;
injections of collagen or other filler within the last 2 weeks in the intended application areas laser;
intensive tan of less than 4 weeks.
Now that we have understood the nature of the therapeutic use of lasers for acne, I think, will be more clearly understood and answers to frequently asked questions relating to this topic.
Is it possible to combine laser acne treatment with taking Roaccutane?
I emphasize: not only can not be combined, and a period of 5-6 months after taking Roaccutane should be avoided deep chemical dermabrasion and laser treatment because of the possibility of pigmentation, as Roaccutane is a photosensitizer.
How to prevent the possible side effects of the treatments?
Laser treatment - this is primarily exposure to heat, so postprotsedurny period may develop side effects such as temporary redness and swelling in the treatment zone. For example, for 4 days after the treatment with the CO2 laser is necessary to avoid contact with the water formed crusts. Also, after the CO2 laser applications need three times a day to handle tough skin (5%) solution of potassium permanganate. After impact with Erbium laser polished site for 6-7 days is treated with an antibiotic ointment to the disappearance of peeling. Full recovery is from three to eight weeks, depending on the depth of grinding.
During this period it is necessary to exclude the impact of UV on the skin affected by the treatment. Of course, this should tell the patient before the procedure, as well as the possible feeling some discomfort in the treatment area, which will speed independently. And be sure to alert the patient that the appearance of such serious adverse effects such as blisters, ulcers, scars or scabs, skin discoloration (although very rare, but still found!), In no case be self-medicate, but should seek medical advice immediately.
Is there a cure for acne 1-2 treatments?
No. Requires a course of laser treatment that is chosen, dermatologist, depending on the nature of acne occurrence and characteristics of the patient. The average duration of treatment is from 4 to 10 weeks, 1-2 times a week.
If laser treatment, especially in severe forms of acne, you need to remember what caused the disease. To achieve full recovery and stable effect requires an integrated approach to the problem of providing for the elimination of both external and internal factors of acne development. The course of laser treatments - one of the components of complex treatment along with antibacterial and hormonal therapy, and after the end of this course is very important to prevent recurrence.
