Why Patch Testing Matters for Laser Tattoo Removal
GHB Clinic, Where knowledge meets advanced treatments for your best skin yet.

Before starting laser tattoo removal, it’s important to understand how your skin may respond. A patch test for laser tattoo removal helps confirm safety, especially for Fitzpatrick IV–VI skin tones, cosmetic tattoos (PMU/eyebrows/lips), or anyone with a history of sensitivity or post-inflammatory hyperpigmentation (PIH). This quick and low-risk step, lets your practitioner fine-tune wavelength, pulse duration, and energy for effective results.

What Is a Patch Test in Tattoo Removal?
A patch test involves treating a small area of your tattoo with the laser during your consultation. We then observe your skin’s reaction over the next 7–10 days before proceeding with full treatment. This allows us to:
- Identify any unusual skin responses
- Fine‑tune laser settings for maximum safety and effectiveness
- Ensure peace of mind before you commit to a full session
Why Do We Always Patch Test?
Laser tattoo removal is extremely safe when performed correctly. A patch test helps us make sure we’re using the right approach for your skin and ink. This is particularly important for delicate or pigment‑dense areas.
- Skin Safety – Confirms your skin tolerates laser energy without triggering blistering, scarring, or post‑inflammatory hyperpigmentation (PIH).
- Precision Settings – Helps select the most effective wavelength, pulse duration, and energy level based on your skin tone and ink colour/type.
- Medical Best Practice – Especially important for clients with Fitzpatrick IV–VI or a history of PIH or keloid scarring.
- Cosmetic Tattoo Safety – Essential for eyebrow tattoos, lip liner, and PMU, where certain pigments can react unpredictably. See our Cosmetic Tattoo Removal page.
Leading guidance from NHS laser services and the British Medical Laser Association supports a pre-treatment laser test patch to optimise parameters and reduce risks such as PIH or scarring, particularly in Fitzpatrick IV–VI and PMU pigments. (See: NHS patient info · BMLA on test patches)
Who Needs a Patch Test?
We recommend a patch test for:
- All first‑time tattoo removal clients
- Medium to dark skin tones (Fitzpatrick IV–VI)
- Coloured tattoos or cosmetic tattoos (eyebrows, lips, eyeliner)
- People with a history of eczema, sensitive skin, PIH, or keloid scars
How Long After a Patch Test Can I Start Treatment?
We typically wait 7–10 days to ensure your skin has healed and there are no unexpected reactions. Your practitioner will assess the area and give you the go‑ahead for your full laser session.

What Happens If There’s a Reaction?
Reactions are rare, but if your skin shows irritation, we will:
- Adjust the settings or laser type
- Delay treatment until the area has fully recovered
- Refer for dermatology review in very rare cases
This approach helps avoid long‑term risks like blistering, scarring, or discolouration, making your treatment safer and more predictable.
