I finished 6 weeks with Tashia and I really noticed the deeper lines on my forehead are lessoning. I go to a coffee shop after with no makeup on and a guy bought me a smoothie. So it must be working. She even said my skin is quite tight already. Did use tightening serums before I started going for years. It’s great to get feedback. You even get a skin journal you can write in for recording the improvement. She uses Korean Serums
