What does cupping and IASTM actually do? Well in order to explain this, we need to discuss what fascia is. Fascia is an intertwining web of connective tissue that connects literally everything. We use cupping and/ or IASTM to lift or compress the top tissue layers as well as incorporating movement to create heat or “controlled inflammation” in order to allow for the hyaluronic acid binding points to separate and collagen fibers to realign to parallel pieces that slide with each other in the appropriate movements rather than perpendicular pieces that fight and create further binding or disrupted smooth movement patterns. 

Here is a blog that discusses fascia as a living matrix, it’s pretty cool:
