It is important to shave the area to be treated 24 hours before and avoid exposure to the sun or the use of self-tanners to ensure safe and effective results.

Using protocols with a lot of watts or with a lot of joules DOES NOT guarantee good hair removal, a good flow in joules is necessary for every square centimeter of skin and with the right pulse, taking into account the phenomenon of scattering and the type of skin and the number of the session (it is important to increase the fluency in each session).

It's a less damaging mode and, therefore, tends to be less efficient. It is more dependent on the person who practices it and if it is not used properly it tends to leave residual hair that ends up being very difficult to remove.

60 joules in 30 milliseconds is not the same as in 100 milliseconds. Being able to give short pulses helps improve the effectiveness of treatment, but it can also increase risks. Protocols must be followed.

More wavelengths don't mean more efficiency. Each wavelength has its benefits, but it has been proven that the lower wavelengths have a better melanin absorption factor helping the effectiveness of the treatment, while the higher lengths are deeper and can be absorbed by water, which helps darker skin phototypes. Using several lengths at the same time makes it necessary to give up part of the advantages of each of them.

It is very common to do sessions every 4 weeks, but it is INCORRECT since most of the hair will not have reached its anagen phase and, therefore, the treatment is inefficient.
