Regarding the duration of the effects of the water-glow injection, does the hydration last for more than a month even with just one session?

I heard that water-glow injections are good for replenishing skin moisture, so I'm looking up reviews.

Some people say that the moisture lasts a long time even after just one treatment, while others say that you need to get it regularly to maintain the effects, so I was confused.

Assuming a single treatment, does the relief from inner skin tightness tend to last for more than a month? I would like to hear opinions from those who have received the treatment.
