I have worked for spas on cruise ships and have also worked with the above mentioned product...
Yes...It could be that the therapists you have had in the past have a specific way that they like to sell. Depending on the ship; pressure to "sell" can be high. So you may have been a victim of that!
And the product you speak of..."Musclease Active Body Concentrate". Hehe...Actually a great product! No...it's not going to get rid of your muscle tension forever...but in my opinion- it does help. There's Rosemary and Pine essential oils in it which are soothing for muscle tension and increase circulation. And it's organic.
Most people have had the same experience as you...but hopefully still had a relaxing effective massage!
