Once you have mastered one particular technique, keep learning, so one day, you can say that you are a specialist in micropigmentation.
In my opinion, the best technique to make permanent makeup is "the one you master, the one you prefer, with which you feel more comfortable working and with which your clients feel comfortable and satisfied".
Yes, if you work with a dermograph and you achieve all of the above, that is the best for you,
If you do microblading and just want to make eyebrows hair strokes and they look pretty, this is the best technique for you.
If you work with Softap and you master it, you achieve the different effects ,and the results you want, then that is the best technique for you.
