FAQ Q-Switched laser tattoo removal

FAQ Détatouage
- What is the best way to remove a tattoo?
Tattoos consist of successive layers of inks introduced into the skin. They are therefore supposed to be permanent. Nowadays, it is very common to meet people who are looking to have their tattoos removed for personal or professional reasons. The methods used 30 years ago left scars, were painful and ineffective. The development of the Q-Switched laser has really improved treatment results. This laser allows your doctor to remove the majority of tattoos successfully and without the risk of scarring.
- How does the laser erase tattoos?
Visible light is made up of several colors and therefore of several wavelengths. The laser will target the tattoo with the energy of light thanks to a specific wavelength. The laser beam safely enters the skin and acts as a targeted shock wave that will cause tattoo inks to explode into microparticles. These in turn will be eliminated naturally by the human body's immune system. Thanks to the precision of the laser beam, your doctor can easily follow the outline of your tattoo without damaging the surrounding healthy tissue.
- Are there any scars?
The Q-Switched laser uses PhotoAcoustic energy. The exposure time of the laser beam is around a nanosecond. These are the safest and most effective lasers for tattoo removal. If you follow your doctor's instructions concerning care after the session, the consequences of treatment are relatively light and the risk of scarring is low.
- How many sessions are needed to clear a tattoo?
Once the decision is made, time will be your ally. This question is complex because it is related to the work of the tattoo artist: in general, the number of sessions depends on the size of the tattoo, the density, the color of the type of ink used, the depth in the skin. We note, for example, that the inks and pigments used in France are more resistant than American inks. It usually takes 6 to 15 sessions for a professional tattoo, while amateur tattoos only require 4 or 5. Each session should be spaced at least 8 weeks apart to allow your immune system to operate effectively.
- Will the tattoo be completely erased?
After the first treatments, you will notice that some of the treated areas have lightened. Over time the tattoo fades, and the skin regains its natural color. However, there may sometimes remain “rebellious” areas: during the initial information consultation, the doctor will examine your tattoo and inform you of the risks of residual traces.
- Do all lasers erase multi-colored tattoos?
Most lasers have only two wavelengths to target dark inks and red inks. The Revlite Multilite System uses advanced technology that allows it to deliver up to four wavelengths and treat certain multi-colored tattoos, such as brown, orange, certain greens, and blue. Yellow, light green and sky blue inks are the most difficult to remove and may require additional treatment.
- Is it painful?
The Q-Switched laser uses PhotoAcoustic technology and emits ultra-short laser pulses. At each impact, patients feel like a rubber band hit, followed by a slight feeling of warmth. Some patients experience moderate discomfort. However, it is possible to use topical numbing creams, or skin cooling systems.
- What kind of aftercare will I need?
Antibiotic or moisturizer cream should be applied immediately after treatment, and the treated area should be kept clean. Follow your doctor's advice diligently. You can shower the next day without rubbing the treated area.
- What is the best tattoo removal laser?
The Revlite laser is among the best in the world France. It is a very safe technology, including for darker skins, which are the most fragile. While there are a number of centres that provide tattoo removal treatments, please keep in mind that in France only certified doctors are allowed to use Class 4 medical lasers.
