You're halfway through laser PMU removal and the fading has stopped. The shape's better, but there's still a stubborn yellow or orange undertone that won't budge no matter how many sessions you do. That's when we shift to saline removal.
Laser works by shattering pigment particles so your body can clear them. But some PMU pigments - especially the ones with yellow or warm undertones - don't respond well to laser light. They either don't absorb the wavelength, or they've already been broken down as much as they're going to break. That's where saline comes in.
What saline removal actually does
Saline removal doesn't use energy. It uses a sterile saline solution and a technique similar to the original PMU application - we reopen the skin at the pigment layer and introduce saline, which draws the pigment up and out as the skin heals.
We use a tattoo machine or manual tool to create micro-channels in the brow area, saturate the channels with the saline solution, and let your body push the pigment out during the healing process. The result is a gradual fade over the next several weeks.
"Saline is slower than laser, but it works on pigments that laser can't touch," says Billy DeCola, Studio Kiku founder. "If you've been stuck at a certain level of fade for months, saline is usually the move."
When we recommend saline over laser
We don't start with saline. We start with laser PMU removal because it's faster, less invasive, and handles most pigments well. But we'll suggest saline when:
- You've done several laser sessions and the pigment has stopped responding
- There's a yellow, orange, or flesh-toned undertone that laser can't break down
- The remaining pigment is light enough that laser would risk heating the skin without shattering much pigment
- You want to remove the last traces after laser has done most of the work
Saline is the finishing tool. It's not usually the first option, but it's effective when laser reaches its limit.
What to expect during a saline removal session
The session feels similar to getting PMU done in the first place - we're working at the same depth in the skin. We numb the area first, then use a machine or manual tool to reopen the channels where the pigment sits. The saline solution is applied and worked into those channels.
You'll have some redness and swelling immediately after. The treated area will scab over the next few days as it heals, and the pigment gets pulled up with the scab. Don't pick at it - let it fall off naturally or you'll interfere with the lightening process.
Healing takes about two weeks. You'll see the most noticeable fade once the scabs are gone and the skin settles. Sessions are spaced 6-8 weeks apart to give your skin time to fully heal between treatments.
We cover the full process in detail on The Faded Podcast - Billy walks through the technique, what clients should expect, and how saline fits into a removal plan.
The honest part
Saline removal is more invasive than laser. You're reopening the skin, so there's a longer healing window and more aftercare involved. The treated area will look rough for about a week - plan around that if you have events coming up.
It also takes more sessions to see significant results compared to laser. Where laser might remove 30-40% of the pigment per session in ideal cases, saline is slower and more gradual. It's effective, but it's not fast.
And saline won't help if the pigment has migrated deep into the dermis or scarred in. If the PMU was applied too deep or if there's already scar tissue, saline has limits. We'll tell you during the consultation if we think it'll work for your situation.
If you're dealing with stubborn PMU brows that won't respond to laser, saline removal might be the solution. We'll look at your brows in person, assess what's left, and tell you whether saline is the right next step or if laser can still do more work. Book a free consultation at our Vancouver, Langley, or Vaughan studio and we'll walk you through the options.
