There are different types of tattoos and this gives rise to the probability of a single laser not being able to remove all the tattoos. Some of the major types of tattoos are:
- Professional tattoos: They are applied to the deeper layer of the dermis and require repeated treatment to remove
- Amateur tattoos: They are superficially applied by the use of handheld devices and can be removed easily. They also fade easily
- Cosmetic tattoos: These are also called permanent makeup and are difficult to remove due to the presence of iron oxides as well as titanium dioxides
- Traumatic tattoos: They are made to hide some injury and can also be hard to remove.
