Why the wavelength matters
Different tattoo colours absorb different wavelengths of light. Choosing the right wavelength helps us target the pigment while considering how your natural skin pigment will respond.
Our system offers two treatment wavelengths:
- 1064 nm: commonly used for black ink and some darker pigments. It is less strongly absorbed by melanin than shorter wavelengths, making it an important option when assessing darker skin tones.
- 532 nm: used for suitable red and some orange pigments. It interacts more strongly with natural skin pigment, so careful skin assessment and wavelength selection are essential.
Some colours respond less readily to these wavelengths. We will explain any limitations before you commit to treatment.
No single laser system is equally effective on every tattoo colour.
Why we use an actively Q-switched laser
“Q-switched” describes how the laser releases energy in a short, powerful pulse. Our British-made solid-state Nd:YAG system uses active Q-switching, with an externally controlled switch governing when that pulse is released.
The pulses last nanoseconds—billionths of a second. Delivering energy over this short period helps target pigment while limiting the time available for heat to spread into surrounding tissue.
However, the quality of treatment depends on more than pulse duration alone. Wavelength, energy, spot size, beam characteristics and practitioner technique all influence how the skin and tattoo respond.
At Remedi, we combine this technology with careful assessment and considered settings. We adjust treatment according to your tattoo’s response and how your skin has healed.
Why stronger treatment is not always better
Increasing the energy does not automatically produce a better result. Skin pigment also absorbs laser light, and excessive treatment can increase the risk of injury.
Before each session, we consider:
- Your skin tone and any recent sun exposure.
- The tattoo’s colours, density and layering.
- Its location and previous treatment history.
- Your skin’s recovery from the last appointment.
- Any changes in your health or medication.
- Whether the aim is removal or fading for a cover-up.
These details help us select appropriate settings and decide whether treatment should proceed, be adjusted or be postponed.
