What are the benefits of LDM, and do you recommend water-glow lifting?

I prefer comfortable treatments over overly stimulating procedures, so I am looking into lifting treatments that provide ample hydration. Among them, LDM caught my eye because there are so many positive reviews. I believe one of the key advantages of LDM is that it uses high-density ultrasound to draw moisture deep into the skin. Unlike other stimulating lasers, I was told during my consultation that LDM provides immediate results in skin soothing and hydration; is this true? I’ve heard that many people get this treatment before weddings or important appointments; how long should I expect the effects to last? I want to achieve smooth, hydrated skin without pain, so I would appreciate some real recommendations and advice from those who have experienced it firsthand!
