Tattoo removal itself is relatively simple and there are many accepted methods to remove unwanted pigment, however the difficulty is in attempting to minimise the damage to the surrounding skin while doing so. Unfortunately there is at this time no perfect system which can handle all possible circumstances without risk.
Laser.
Laser systems are expensive to run and maintain, problems of both scarring and incomplete removal are well documented. Lasers use very high energy, with very short pulses to superheat the ink particle causing it to explode in the skin, the ink particle sized is reduced and the bodies immune response can forage the particles, and the resultant small particle size becomes less visible. This particle detonation can damage surrounding skin cells leading to permanent scarring or pigmentation change. Even with the latest laser systems and multiple laser types certain ink particles reflect much of the laser light energy meaning the particle cannot be broken down sufficiently for removal. The skin only has capacity to withstand a certain amount of energy thus it becomes impossible to increase the amount of energy required to destroy difficult colours without causing severe skin damage. Certain pigments (permanent cosmetics) and areas are also not suitable for laser treatment.
Surgical or mechanical.
There are many surgical methods including excision, skin graft and abrasion techniques to remove the particles, however while these methods can guarantee complete colour removal they are very destructive to the skin and will nearly always lead to heavy scarring.
Chemical Removal.
Chemical removal has been used for centuries to effect tattoo removal, unfortunately many of the chemicals that have been used can be highly acidic or only partially effective. Most methods either attempt to destroy or bleach the pigments, or disrupt or destroy the skin tissue. However the ink pigments can be quite resultant to attack and are typically much tougher than skin cells and the damage to the surrounding skin is often excessive and permanent. As the particle builds up skin attachments over time they can also be difficult to dislodge.
There are other methods of chemical removal such as the use TriChloroacetic Acid (TCA) or Gylcolic Acids. These work by reacting with the the epidermis, weakening the binding properties of the lipids that hold the dead skin cells together. This allows the outer skin to dissolve or peel away revealing the underlying skin. TCA is usually applied to the surface of the skin while Glycolic is often applied with a tattoo or permanent makeup machine. While these methods can be successful they are not designed for the purpose of tattoo removal. The removal of the epidermis can pull ink upwards in the skin from the dermis which may get caught in the reforming epidermis. However there is no guarantee that the ink will raise sufficiently if at all. Incorrect use or poor formulations can be potentially harmful.
At home remedies, such as tattoo fade creams.
There are now also a number of systems that use home applied creams or devices to act upon the surface of the skin claiming to effect removal. Unfortunately the epidermis (top layer of skin) is extremely effective at preventing any substances from penetrating the skin especially into the dermis. Sometimes these are used with scrubbing or abrasion techniques or equipment to remove or thin the epidermis, however as with the mechanical techniques mentioned above to grind off the epidermis is potentially damaging. To then effect the actual pigment particles massive quantities or very strong chemical formulas would need to be utilised, which in reality would probably result in other adverse health effects first. There seems to be no independent research that substantiates the claimed results for these products.
By comparison Rejuvi Laboratory manufacture a wide range of cosmetic products utilising the latest technological and scientific research and development available, including pentapeptides etc. Rejuvi also have lactic acid based skin peels which can safely remove substantial layers of the epidermis (for professional use only). Thus if surface based products that could be applied at home were possible then we would already manufacture it. But we don't ! |
