I'm thinking of trying Rivicol. How long does the procedure take?

With the change of seasons, it seems my skin barrier has completely broken down. Even slathering on expensive moisturizer doesn't resolve the inner dryness at all, so I'm thinking of trying Revicol. Haha. As I get older, fine lines are increasing, and I can see my skin becoming dull and losing its firmness right before my eyes. It just makes me sigh every time I look in the mirror. I feel like home care has reached its limit, so I'm planning to get Revicol injections, which are said to directly replenish collagen. I'm curious how long the dewy glow effect from deep within the skin lasts, and how often I should schedule the treatments. Are there any people with extremely dry skin like mine who have definitely gotten rid of their inner dryness after getting Revicol?
