Hyaluronic Acid Gel for Facia stretching

Anyone tried site shots to assist with facia stretching for lagging body parts? An alternative to SEO's which are clearly not ideal long term and just give you a fake look. I see some pros use it.

Never heard of it, I only see this in my face wash. How does it work?

So far it has a localized effect for a few days-workout pump with it in is intense and remains for tow days. The theory is this pressure will cause the fascia to stretch given the muscle room to grow.
