Fractional photothermolysis and Fraxel: areas of application.
Fractional laser rejuvenation is used to address many cosmetic concerns:
- remove wrinkles, including deep ones;
- Repair healing tissue (including stretch marks, scars, acne scars);
- Restores skin pigmentation and improves skin tone;
- Improves skin elasticity and firmness (turgor), corrects blurred ovals on the face.
The advantage of fractional laser rejuvenation is undoubtedly the ability to work on the upper and lower eyelids, allowing you to firm your skin, restore its elasticity, firmness and a refreshed appearance.
The areas of application of both procedures are similar, so the final decision in favor of photothermal therapy or DOT regeneration should be made by the physician after an initial examination and consultation.
Characteristics of the photopyrolysis process
The fractional photothermolysis procedure does not require general anesthesia. The exposed skin is treated with a numbing cream to reduce discomfort.
The main difference between the DOT procedure and the Fraxel technique is the type of laser used. In the first case, carbon dioxide is used, and in the second, erbium. They differ in penetration depth, wavelength, and tissue absorption of optical radiation:
- With Fraxel, the beam penetrates to a depth of approximately 1. 5 mm without affecting deeper tissue. Laser rejuvenation on SmartXide devices also works on the superficial layer;
- The special technology of the Fraxel device allows you to achieve uniform radiation in all treatment areas, which completely excludes the possibility of overworking or conversely underworking certain areas;
- During Fraxel or DOT regeneration, each heat-acting microdomain is thinner than a human hair in diameter, and tissue damage does not exceed 20% in each specific area. The flexible adjustment of the SmartXide laser allows you to apply micro-damage meshes in layers at a given interval size or in continuous light spots.
It's important to note that the outcome of the surgery does not only depend on the type of laser. Part of the photothermal action in the before and after photos shows that the qualifications of the doctor play an equally important role: modern techniques in the hands of an untrained beautician can cause serious damage.
Which is more expensive: Fraxel or DOT revival?
The results after applying Fraxel technology and fractional laser rejuvenation (DOT) were evident from the first session. However, for best results, multiple treatments are recommended. The effect of the first DOT procedure is even more visible because the SmartXide laser, unlike Fraxel, affects the superficial layers of the skin, stimulating its active renewal.
After Fraxel, the results gradually increased, reaching a maximum within 2-3 months and then lasting up to 5 years. With the DOT technique, the results are immediate, but a second surgery may be required after 12-18 months.
One partial photothermal therapy costs less than Fraxel, but the final price can vary widely depending on the size of the treated area and the individual characteristics of the patient's skin.
Both of these techniques have become proven means of healing and rejuvenating the skin and eliminating cosmetic imperfections. The price of photothermal therapy wins in the context of other procedures that allow you to deal with the same drawbacks in an effective and safe way (especially compared to the price of cosmetic surgery).
