Why the technology matters as much as the practice
Most patients researching tattoo removal focus on finding the right provider — which matters, but it's only half the equation. The laser technology used matters just as much, because Q-switched and picosecond lasers work differently at a physical level, and different ink colors respond better to one than the other. A practice that only owns one type of laser is, by definition, using the same approach on every tattoo regardless of what would actually work best.
At Plump Medical Spa, Dr. Mortazavi has both Q-switched and picosecond (PicoLazer) technology available, and selects — or combines — the right one based on your specific tattoo's ink composition.
The core difference: pulse duration
Both technologies work the same basic way — delivering a burst of laser energy that shatters tattoo ink into particles small enough for the body's immune system to clear. The difference is how long that burst of energy lasts, measured in almost incomprehensibly short units of time.
Picosecond
~1,000x shorter
A nanosecond is a billionth of a second. A picosecond is a trillionth of a second — roughly a thousand times shorter. The shorter the pulse, the smaller the ink particles it shatters ink into, and smaller particles clear from the body more efficiently. This is the entire basis for why picosecond technology has become the newer standard, without making Q-switched technology obsolete.
Q-switched vs. picosecond, side by side

Why owning both technologies matters
Most multi-colored tattoos don't have just one ink type — they have several, layered together. A practice with only one laser technology treats every color in the tattoo identically, regardless of how each color actually responds. At Plump, Dr. Mortazavi can select — or alternate between — Q-switched and picosecond technology within the same treatment series, matched to how each color in your specific tattoo is responding.
What this means for your treatment plan
In practice, most patients don't need to choose a technology themselves — Dr. Mortazavi assesses your tattoo's ink colors, density, and prior treatment history (if any) at consultation and determines the appropriate technology or combination. Patients who have had previous tattoo removal elsewhere with disappointing results, particularly on colored ink or after their fading plateaued, are often good candidates for adding picosecond technology to the plan.

Frequently asked questions
What is the difference between Q-switched and picosecond lasers?
Q-switched lasers deliver pulses lasting nanoseconds (billionths of a second), while picosecond lasers deliver pulses roughly a thousand times shorter, measured in trillionths of a second. The shorter pulse of picosecond technology shatters ink into smaller particles, which the body clears more efficiently, often improving results on colors and ink types that respond poorly to Q-switched treatment alone.
Is picosecond always better than Q-switched for tattoo removal?
Not universally. Q-switched lasers remain highly effective for black and dark ink, and are a proven, long-standing standard. Picosecond technology tends to outperform Q-switched specifically on stubborn or lighter ink colors, and on tattoos that have plateaued after multiple Q-switched sessions. Having both technologies allows the right one to be matched to the specific ink rather than assuming one is universally superior.
Which laser is better for colored tattoos?
Picosecond lasers generally perform better on a wider range of colors, including greens and blues that are traditionally difficult to treat with Q-switched technology alone. Black ink responds well to both technologies.
Can Q-switched and picosecond lasers be used together on the same tattoo?
Yes. Some tattoos respond well to alternating or combining both technologies across a treatment series, particularly multi-colored tattoos with a mix of ink types. Dr. Mortazavi assesses the ink composition at consultation and adjusts the technology used session to session as the tattoo responds.
Does having two laser technologies mean fewer sessions?
Not necessarily fewer sessions, but potentially more effective ones. Using the correct technology for a given ink color reduces the chance of a session producing minimal visible fading, which is a common frustration when a single-technology provider treats every tattoo the same way regardless of ink type.
