The fascia stretching is permanent (Exhibit A, Greg Valentino). Not sure if it can be undone through surgery. I’m interested in seeing how these synthol freaks hold up at age 80. I’m thinking soiled-diaper-type sagging. Eewh.
Of course your body will absorb the synthol over time. The muscle fascia will shrink MOSTLY back to its pre-synthol size, but will almost certainly lose some of its elasticity. Anyone else with real world experience?? (hopefully not on this site… )
