How was the Jubelook effect?

There are many skin boosters available these days, but I still consider Rejuran and Juvelook to be the top two. However, I tried Rejuran before and experienced an allergic reaction, so I am now considering Juvelook as my next treatment. For those who have received Juvelook, what were the results like? Do you definitely feel your skin becoming firmer? Since my skin is naturally thin and sensitive, I am looking for a skin booster that can make it firmer. I have also heard that nodules can occur as a side effect; were everyone who received Juvelook fine? I am curious if the effectiveness is good considering the cost and the potential for side effects.
