Do the pain from the Rejuran Healer procedure and the embossing marks last a long time?

Hello

My skin is becoming severely dry deep down, so my makeup keeps caking and my skin texture looks rough. I am looking into skin booster treatments.

No matter how much nourishing cream I apply, the inner dryness of my skin doesn't go away, so I am considering getting Rejuran Healer. However, after searching online, I found many reviews stating that the pain is quite severe since it is an injection procedure, so I am having trouble making a decision.

I am curious if there is a significant difference in pain between receiving injections via hand and using a machine like a macro-projector. I would also like to know how many days it usually takes for the embossing marks or bruising on the face after the procedure to naturally disappear. Please share an honest review regarding the recovery period and the actual improvement in internal dryness.
