The ink from the skin’s dermis layer must be removed in order to remove a tattoo. Due to the usage of some contaminated ink, inadequate skin cleaning, & dermis penetration, getting a tattoo can result in bacterial, fungal infections, allergies, an unfavorable immunological reaction, and tumors. In 2021, the size of the global tattoo removal market was $4.34 billion. By 2030, it is anticipated to reach $12.15 billion, reflecting a CAGR of 12.1% over the anticipated period of 2021–2030.
One may choose tattoo removal for a variety of reasons, including military duty, new employment, tattoo complications, stigma against the tattoo culture, and reversing a hasty tattoo decision.
People have used a variety of techniques, including a few home cures, to get rid of tattoos. Reaching the dermis layer and taking away the ink are necessary steps in tattoo removal. Several of the techniques are:
a.) Laser Tattoo Removal
b.) Non-Laser Tattoo Removal
a.) Laser Tattoo Removal
In the laser procedure, the tattoo is exposed to powerful light pulses that break down the pigments in the dermis layer. As the lymphatic system removes the ink and tattoo pieces, the tattoo starts to fade. Despite being the safest option, laser therapy can nevertheless result in blisters, bruising, and scabbing. Different types of laser therapy are employed.
The notion of selective photothermolysis, in which laser light of various wavelengths is absorbed by various chromophores, provides the foundation for quality-switched lasers (QSL). In the case of tattoos, the chromophore is the exogenously applied ink and is heated for no longer than its TRT (thermal relaxation time), which causes the pigment-containing cells to rupture, destroying the ink layer. The time required to transmit 50% of the heat energy away from the target tissue is known as the TRT.
Tattoo removal can be done with non-ablative or ablative fractional resurfacing (AFR) lasers, which are typically utilized for anti-aging procedures.
When using a fractional laser, tiny, light-filled columns are formed that extend through the epidermis and into the dermis. AFR that vaporizes the skin’s outer layers, like CO2 and Erbium, is more invasive and takes longer to recover from. The skin layers repair and rebuild (fenestrate) as a result of this process, which boosts the creation of collagen.
Picosure, CoolTouch, Fraxel Restore, and N-lite are examples of non-ablative fractional resurfacing (NBFR) techniques that are less invasive & take lesser time to heal. Although they too employ heat, the skin is not damaged.
b.) The Non-Laser Tattoo Removal Methods
Excision
To remove a tattoo using this approach, a scalpel must be used to cut away a section of the person’s skin. A surgeon performs it while under local anesthetic. Scarring and bruising are the outcomes.
Cryosurgery.
Cryo is the Greek term for freezing cold, and surgery is the word for manual labor. In this technique, a cold liquid that is around 196 °C (321 °F) is sprayed or rubbed on the skin area to break apart skin. Cryoneedles are furthermore used in several operations.
Dermabrasion
In order to see the immaculate skin layers behind the tattoo, the top layers of skin must first be removed using sandpaper after a numbing solution has been sprayed on them. To remove the skin, a rotating abrasion brush is employed. It needs local anesthetic and could result in bleeding and bruising. Although the tattoo may fade, it cannot be entirely removed. Before beginning the process, a freezing substance, such as liquid nitrogen or CO2, is applied to the skin where the tattoo is designed. Vasoconstrictors, such as epinephrine, are used to reduce bleeding after the procedure.
