Fractional photothermolysis and Fraxel: field of application.
Fractional laser rejuvenation is used to solve many aesthetic problems:
- removal of wrinkles, even deep ones;
- correction of healed tissues (including stretch marks, scars, acne scars);
- restoration of skin pigmentation, improvement of complexion;
- improving the elasticity and tightness of the skin (turgor), correcting the blurred oval of the face.
The undoubted advantage of fractional laser rejuvenation is the ability to work on the upper and lower eyelids, which allows you to firm the skin, restore its elasticity, firmness and a fresh appearance.
Both procedures have similar areas of application, so the final decision in favor of photothermolysis or DOT rejuvenation should be made by a doctor after a preliminary examination and consultation.
Characteristics of photothermolysis procedures
Fractional photothermolysis procedures do not require general anesthesia. The skin at the site of exposure is treated with an anesthetic cream, which reduces the level of discomfort.
The main difference between the DOT procedure and the Fraxel technique lies in the type of laser used. In the first case, carbon dioxide is used, in the second erbium. They differ from each other in terms of depth of penetration, wavelength and degree of absorption of light radiation by tissues:
- when using Fraxel, the beam penetrates to a depth of approximately 1. 5 mm, without affecting the tissues located deeper. Laser rejuvenation on the SmartXide device also works with surface layers;
- the special technique of the Fraxel apparatus allows to obtain uniform radiation on all treated areas, which completely excludes the possibility of excessive or, conversely, insufficient work in certain areas;
- each micro-zone of thermal action during Fraxel or DOT rejuvenation has a diameter thinner than a human hair and no more than 20% of the tissues in each specific area are damaged. The flexible adjustment of the SmartXide laser allows you to apply a micro-damage network in layers, with a certain size of intervals or a continuous light spot.
It is important to note that the result of the procedure depends not only on the type of laser. With fractional photothermolysis in the before and after photo, it can be seen that the qualifications of the doctor play an equally important role - modern technology in the hands of an untrained cosmetologist can cause great harm.
Which is more expensive: Fraxel or DOT rejuvenation?
The result after applying the Fraxel technique and fractional laser rejuvenation (DOT) is evident from the first session. However, to get the best effect, multiple treatments are recommended. The effectiveness of the first DOT procedure is visually more pronounced, since the SmartXide laser, unlike Fraxel, acts on the surface layer of the skin, stimulating its active renewal.
After Fraxel, the results gradually increase, peaking in 2-3 months, after which they persist for up to 5 years. With DOT technology, the effect is pronounced immediately, but a second procedure may be required after 12-18 months.
The cost of a fractional photothermolysis session is lower than that of Fraxel, however the final prices can vary considerably depending on the size of the treated area and the individual characteristics of the patient's skin.
Both technologies have established themselves as a reliable means of healing and rejuvenating the skin, eliminating cosmetic defects. The price of photothermolysis wins against the background of other procedures that allow you to deal with the same disadvantages effectively and safely (especially compared to the prices of cosmetic surgery).
