Less common reactions are classified as delayed reactions. The list includes: inflammation, infection, pigment changes, and systemic allergic reactions. How long these reactions last is not normal, but following proper care is still the customer’s first line of defense.
Inflammation is not synonymous with infection. Laser tattoos can remove infections, but they are rare. Pain, fever, redness, and functional changes at the tattoo site usually make customers think they are infected. The reaction of a certain part is considered to be a local acute inflammatory reaction. Inflammation is a complex reaction of the body caused by trauma, cell/skin damage or irritation. This is actually a protective response provided by the immune system. The body’s response to injury is to activate the immune system and vascular system. Inflammation occurs to eliminate the cause of cell damage, remove damaged cells, and initiate tissue repair. Therefore, inflammation is a positive response, indicating that a healthy individual has a healthy immune system.
Infections are more complicated and occur when bacteria have an inflammatory response. Customers will experience the same pain, fever, redness, and functional changes, accompanied by fever, and if severe, lymph nodes will be swollen. The infected person feels uncomfortable. It will affect your overall sense of health. Of course, if you think you have an infection (more serious complications), please contact your clinic.
Underpigmentation and hyperpigmentation.
Skin lightening (hypopigmentation) or skin darkening (hyperpigmentation) is also a delayed response to laser tattoo removal. Both are common reactions to laser tattoo removal. This risk occurs when the surrounding skin absorbs the heat and energy of the laser. Melanin provides us with pigment. The pigment exists in the skin/epidermis and will be affected by the laser, causing skin pigmentation to change. Melanin is produced by melanocytes located deep in the skin under the tattoo. The tattoo is located about 4 mm deep in the skin. The laser reaches and smashes the ink, but it does not reach and smash the melanocytes. The body responds to the loss of melanin in the skin/epidermis by replacing the lost pigment by producing melanin. After the last laser treatment, this process takes 3-12 months. Remind customers to be patient, especially those with dark skin. These pigment changes are rarely permanent because they are skin changes rather than deeper tissue changes.
Hyperpigmentation is caused by excessive laser irradiation in a certain place, and the broken ink will enter the surrounding tissues and stay there. This is common in cultures where the dermis is known to be thinner.
