How many days do the raised marks on the face last after the Libby Heal procedure?

I became interested in Livy Heal because I heard it is effective for skin regeneration and tone-up. I am curious how long the needle marks or raised bumps typically last immediately after the procedure. As a working professional who has to go to work right away, it would be inconvenient if the marks remained visible on my face for too long. I would like to know in advance the average time it takes for redness or marks to subside. I am also curious whether the Livy Heal procedure involves applying a machine across the entire face or if the injections are administered manually in a tight, detailed manner. Please let me know how painful the procedure is and whether it is tolerable if anesthetic cream is applied. How many Livy Heal injections are typically required to address overall dryness? It would also be helpful if you could share the average treatment cycle.
