Microblading, permanent make-up, and lip blush removal — and the one risk that makes the patch test non-negotiable
Eyebrow and cosmetic tattoo removal — microblading, permanent make-up, and lip blush — carries a specific risk that body tattoos do not: paradoxical darkening, where laser can oxidise iron oxide or titanium dioxide pigments and cause immediate permanent darkening instead of fading. At Dental & Wellness London every cosmetic tattoo removal begins with a free patch test, and we do not proceed with laser where darkening occurs.

The patch test is non-negotiable for cosmetic tattoo removal — it is the one step that tells us whether laser is safe for your specific pigment before any full-area treatment begins.
| Patch Test — free | A small discreet area is lasered to test pigment response. If clean lightening, we plan a course. If paradoxical darkening occurs, we do not proceed with laser or modify protocols. This is a genuine decision-making step. |
| Treatment course — from £750 for up to 10 appointments | Typically 4–8 sessions spaced several weeks apart. Each session uses a Q-switched laser, which fires in nanoseconds, to break down pigment. A written per-area plan is provided at consultation. |

It can, and this is the major risk we work to avoid. Some cosmetic pigments contain iron oxide or titanium dioxide that can oxidise when lasered, producing paradoxical darkening. That is exactly why we patch test before any full treatment. If the patch test shows a darkening response, we do not proceed with laser, or proceed only with modified protocols.
Typically four to eight if the pigment responds well to Q-switched laser. Modern microblading pigments often respond reasonably; older or low-quality pigments can resist or darken paradoxically. The free patch test determines whether full laser treatment makes sense.
For pigments at risk of paradoxical darkening, often yes. Saline removal uses no laser energy, so it does not trigger oxidation. It is slower — ten or more sessions — but safer for high-risk pigments, and we can refer you to a saline provider if that is the right route.
Because cosmetic pigments respond unpredictably — some lighten, some stay unchanged, some darken permanently. A patch test in a small area shows which response your specific pigment will have before you commit to treatment on a visible part of your face. Skipping it risks lasting disfigurement.
Sometimes, with careful protocols including eye shields, because of how close the pigment sits to the eye. Some clinics decline eyeliner removal due to the risk; we assess case by case at consultation and proceed only if it can be done safely. A patch test is essential, as with all cosmetic tattoo removal.
If you have microblading, permanent make-up, or another cosmetic tattoo you want removed, book a consultation and patch test. We will not proceed with laser if paradoxical darkening is a real risk — we will tell you honestly and, where needed, refer you to a saline provider instead.
