Fibroblast is the treatment people ask me about most once they see a friend's results, and the one they are most nervous about once they see the photos. Both reactions make sense. So let me walk you through it the way I do in a consultation.
What the plasma pen actually does
The pen never touches your skin. It creates a tiny arc of plasma that lands on the surface and makes a micro-point of controlled damage. Your body responds the way it always does to a small injury: it sends in collagen to repair the spot. Line those points up in a grid and the skin between them tightens as it heals. That is the whole trick, and it is why eyelids, crow's feet, and the neck respond so well.
About those dots
Right after the treatment you will have a grid of small brown dots, called carbon crusts, across the treated area. Some swelling is normal for the first two or three days, especially around the eyes. The dots flake off on their own between day five and day ten. Do not pick them. Picking is the one thing that can leave a mark, and patience is the one thing that guarantees it will not.
Stretch marks, scars, and tattoos
The same collagen response is why fibroblast helps soften stretch marks and scars, and why it is one of the options I use for lightening unwanted tattoos. Those treatments are planned differently than a lid lift, so they always start with a consultation where we look at the area together and set realistic expectations.
How many sessions, and when you see it
You will see some tightening as soon as the dots come off, but the real result shows up over eight to twelve weeks as collagen keeps rebuilding. Most areas need one to three sessions, spaced at least six weeks apart. We decide that at your consultation, and your aftercare guide covers everything for the healing week.
