I want to know the recommended dosage and price of collagen boosters.

I've noticed collagen booster treatments like Revicol quite often lately, and I'm curious about the price range. While I understand it varies by clinic, I'd like to know the typical cost for 1, 3, or 5 sessions. I'm also wondering how many sessions are usually required to feel the effects. If the goal is to improve skin texture, elasticity, or fine lines, I'd like to know the recommended interval between sessions and how long the results last. I'd also like to know if receiving just one session is sufficient, or if it's better to plan for at least three sessions from the start. I'm also curious about how long post-procedure reactions, such as swelling, last. Sharing reviews from actual patients or who this treatment is recommended for would be very helpful in making my decision.
