Tattoo removal is becoming more common, especially among younger people. In France, about 25% of those under 30 have tattoos, according to the French Society of Dermatology. Around 20% of tattooed individuals regret at least one of their tattoos, as reported by the High Council of Public Health. The global market for tattoo removal is growing quickly, with a value of 1.29 billion dollars in 2025 and expected to reach 4.87 billion dollars by 2034. Laser treatment is the most common and effective method for removing tattoos. It uses different wavelengths of light to target various tattoo colors. Each session can cost between 100 and 500 euros, and full removal may cost several thousand euros. For example, a health YouTuber named Julien Ménielle spent 5,250 euros on 21 sessions over three years. The process usually requires between five and twenty sessions, spaced one to two months apart, and can take several years to complete. The cost of laser tattoo removal is often ten times that of getting a tattoo. Some centers may use less effective or illegal methods, such as chemical tattoo removal, which involves injecting lactic acid into the skin. This method is cheaper and faster than laser removal but can cause serious skin damage, including necrosis and scarring. Dr. Nicolas Kluger, a dermatologist who specializes in tattoo complications, explains that this technique is an old method from the 19th century and can lead to permanent scars. Chemical tattoo removal is not currently banned in France because of unclear regulations, as the product is classified as a cosmetic rather than a drug or medical treatment. Companies like Skinial, which sell the lactic acid product, acknowledge the possibility of the practice being restricted or banned in the future. In addition to chemical methods, there are online products such as creams and laser pointers that are often ineffective or harmful. These products, which can be purchased for as little as 3.79 euros, are not registered in France as cosmetics or medical devices and may contain toxic substances. Experts recommend consulting a dermatologist who specializes in laser tattoo removal and choosing a practitioner with experience in the field. It is also advised to take time to consider getting a tattoo, as removal is a long and costly process.
