In recent years, microneedle radiofrequency (MRF) method has been gradually replacing fractional laser treatments which were widely used due to their efficiency and lack of competitive treatments. The development of new technologies such as microneedle radiofrequency or Hifu brings spectacular effects while acting at greater depths without discomfort during the procedure.
The operating range of the fractional laser is smaller – it penetrates the skin to a depth of approx. 1.7 mm, while radiofrequency allows work to a depth of up to 3.5 mm, which enables the stimulation of repair processes in the deeper parts of the skin and gives a better lifting effect.
The treatment with the use of a fractional laser, unlike MRF, can be performed only in the autumn and winter seasons, when solar radiation is very low. Convalescence with the use of a laser is also twice as long (5-7 days vs 2-3 days using MRF).
Another advantage of the MRF method is that it is much less painful than laser treatments. The pain related to laser-based procedures deters some people and causes them to abandon the treatment after one session. MRF is performed using parameters that make it comfortable without sacrificing effectiveness.
Treatments using MRF provide better results when working with acne scars, stretch marks, and skin laxity compared to the fractional laser.
One possible drawback of the MRF technique is that it does not exfoliate the epidermis, as opposed to laser treatments which leave the skin with a fresh and bright look. This is not a big disadvantage – it shortens the recovery time and the exfoliation effect can be achieved with much less painful procedures such as chemical peels.
