By any chance, is the Elavie Rituo Skin Booster effective?

Hello. I am writing to the consultation board after looking into treatments due to concerns about my skin's elasticity and complexion, which have recently become noticeably dry and dull. As it is late Thursday afternoon, my skin looks even more dull due to fatigue, and home care alone is not resolving the internal dryness at all. ㅠㅠ So, I am planning to receive professional treatment!!

After researching Elavie Rituo and browsing online reviews, I became interested in the treatment, which is said to be good for strengthening the skin barrier and replenishing moisture. I would like to ask for your opinion on whether this treatment would be suitable for my dry skin condition...

Since this is an injection procedure administered directly to the face, I would like to know about the level of pain, the typical treatment cycle (how many consecutive sessions are usually required to feel tangible improvements with Ellavie Rituo), and the cost. I would also like to know if bruising or redness lasts a long time after the procedure. Thank you.
