How long do the effects of 'water glow injections' last?

My skin suffers from severe internal dryness, so I am seriously considering getting the "Water Glow Injection," which is said to be frequently received by celebrities. Whenever the seasons change or during the winter, my skin feels so tight that it dries out quickly, no matter how much high-quality skincare I apply. Many people around me recommend this injection, saying it makes the skin feel moisturized from within, as if honey has been applied. I am curious to hear from those who have actually received it. Advertisements and clinic promotional materials claim the effects last quite a long time, but I would like to know how long the actual effects last. Additionally, I would appreciate it if you could share your honest reviews regarding the level of pain associated with the procedure and whether the embossing effect that occurs immediately afterward interferes with daily life.
