Years ago, I was one of the first to adopt threadlifting and even performed it on television In those days, we used permanent threads and believed that the results would consequently be very long-lasting to make up for the procedure's expense and attendant downtime. Well, it wasn't long before we learned that the results were short-lived and, no longer being able to justify the expense and downtime involved, I stopped performing the threadlifts altogether. Soon after, threads were removed from the market. More recently, dissolving threads have reemerged. Unfortunately, again results are proving relatively short-lived (not surprising considering that permanent threads didn't last that long). So, moral of the story, be especially cautious when evaluating threadlifting and the claims for its purported benefits. Moreover, early studies were showing an uncomfortably large number of adverse reactions following treatment. Personally, I have been achieving quite gratifying results with the use of injectable bioremodeling agents, such as Profhilo, and skin boosters for the upper inner arms, upper inner thighs, and even crepey, crinkly necks. Best of luck to you.
