PicoWay Tattoo Removal: Sessions by Ink Color?

Here's why the number of PicoWay tattoo removal sessions varies by ink color — including session intervals and what to know before you start.

PicoWay Tattoo Removal: Does the Number of Sessions Really Depend on Color?

If you've been researching tattoo removal, you've probably wondered: "Why does everyone need a different number of sessions? Does ink color actually make a difference?" You may have heard that black ink fades easily, while colors take much longer. So — does the number of PicoWay tattoo removal sessions truly vary depending on ink color?

The short answer is yes. The number of sessions depends on the ink color, depth, and volume — because each color responds best to a different laser wavelength*. That's why it's more accurate to assess your specific tattoo's color and condition first, rather than giving a one-size-fits-all answer like "it'll be done in X sessions."

Wavelength*: A property of laser light. Different pigments absorb different wavelengths, which directly affects how effectively the ink can be broken down and cleared.

  · What PicoWay is and how it works
  · Why the number of sessions varies by ink color
  · How many sessions are typically needed
  · What to know before starting your tattoo removal journey

What Is PicoWay?

PicoWay is a laser tattoo removal device that delivers powerful bursts of laser energy in ultra-short pulses. It works by shattering ink particles into tiny fragments, which your body then naturally eliminates over time.

The ink doesn't disappear all at once — instead, pigment is reduced gradually across multiple sessions. That's why tattoo removal is a process that requires both time and patience across several visits.

Why Does the Number of Sessions Vary by Ink Color?

Each ink color responds best to a different laser wavelength*. According to clinical data on laser tattoo removal, black and blue inks respond well to one wavelength, while red ink responds to a different wavelength — meaning each color absorbs light differently, which affects how efficiently it can be removed.

Research on picosecond lasers also notes that blue and black pigments require a different wavelength than red and yellow pigments. As a result, multi-colored tattoos often require more sessions since each color demands a different approach. Ink depth and volume also play a significant role in determining the total number of sessions needed.

How Many Sessions Are Typically Needed?

Tattoo removal is always performed across multiple sessions. The clinical data referenced above generally indicates that around 7–10 sessions are needed, while also noting that picosecond lasers may achieve visible fading in fewer sessions in some cases.

Sessions are typically spaced about 8 weeks apart to allow the skin adequate time to recover. The total number of sessions required varies considerably from person to person based on ink color, depth, volume, and skin condition — which is why a proper in-person consultation is the most reliable way to set realistic expectations from the start.

What to Know Before You Start

Tattoo removal is not a one-time procedure — it's a gradual process that takes time. Skipping the recommended interval between sessions can place unnecessary stress on the skin, so it's important to allow adequate recovery time between each visit.

Additionally, certain ink colors or formulations may be more resistant to removal, and some pigments may shift in color during the process. That's why it's strongly recommended to have a clinician evaluate your tattoo's color and depth before beginning treatment, so that a realistic session plan and interval schedule can be established safely.

Frequently Asked Questions

Q. Does the number of sessions really vary depending on tattoo color?

A. Yes, it can. Because each color responds best to a different laser wavelength, multi-colored tattoos may require more sessions. Ink depth and volume also have an impact on the total number of sessions needed.

Q. How many sessions does it typically take?

A. Clinical data generally indicates that around 7–10 sessions are needed. Picosecond lasers may achieve noticeable fading in fewer sessions in some cases. The exact number varies considerably depending on the ink color and overall tattoo condition.

Q. How much time should be left between sessions?

A. Clinical guidelines generally recommend spacing sessions approximately 8 weeks apart, as the skin needs time to recover between procedures. The interval may be adjusted based on your individual skin condition.

Q. Does every ink color respond equally well to laser removal?

A. No — response varies depending on the color and type of ink used. Some pigments may be more resistant, and color shifts can occur during the process. It's advisable to have your tattoo evaluated by a clinician before starting treatment.
