Simple. Yes this is in the FAQ under subcision, top post of the scar solutions sub. You can overlap your pumps, the treatment head is small ... to cover the area. Your suctioning for the amount of seconds. You are creating a bruise so be aware of this, ... to develop tissue under the pit. Wear concealer or medical makeup like dermablend if need be (See skin section and makeup).

This is per scar 2-3 pumps on each scar for 4-6 seconds

Passes mean the passes of the whole skin, yes your right by time (4-8 passes). I could be wrong but I thought it was the times per day to do this not passes. Again read the FAQ top of the scar solutions sub, goto subcision section.

You don't know when you have done it enough, it's not a precise science.

You don't have to do that many passes. Read the FAQ, I forget the number but I have different instructions there. You can do less "times" and longer suction on the scars if you wish as well. It's hard for some people to do it this many times per day. If you can do it 3 times per day great.

Is there any video example of this procedure? That could be even more helpful than just plain text explanation.

Yes your creating a bruise, this is why you do cupping. To fill the space with blood that will hopefully make scar tissue under the skin for "natural" filler. Wear concealer if it's a issue. I was right It's not passes it's times per day. Do what you can 3 - 8 times.

No I do not believe there is a video on this. Feel free to make one and share!

There is no exact number to do this, you want to do it at least a few times a day or more for the seconds listed above.

Seriously in need of help, especially from @beautifulambition if you're still active on this site. Would greatly appreciate any advice!

I think I may have suctioned my scars too early after my subsision treatment and I am getting angry red DOT scars from the needle incision points. Do you know if this is an issue I should be worried about, and is there anything that I should do to remedy this?
