The principle of pigment removal is to use the instantaneous high energy emitted by laser to make the irradiated pigment particles expand and rupture due to energy absorption, and some of them are split into smaller particles and excreted, and some of them are swallowed by the human body and excreted through the lymphatic system, thus removing pigment.
In the treatment of dark tissue, due to the strong absorption of laser energy by melanin, there may be a strong pigment explosion accompanied by a strong sound. Pigments in the superficial epidermis will generate out of the epidermis due to energy absorption, forming bleeding spots. Therefore, bleeding and redness are normal phenomena, which are manifestations of enhanced macrophage activity in the body and can accelerate the process of pigment metabolism. Washing the covered tattoo will cause bleeding, because the covered melanin layer will explode after being irradiated by laser, and destroying the covered layer will hurt capillaries. Practice has proved that eyebrow washing with bleeding or bleeding spots is better than that without bleeding. The main reason is that the larger pigment is discharged with the blood in the process of laser breaking the pigment group.
After the first laser treatment, the color of the tissue will become very pale, but after a period of time (ten minutes to dozens of minutes), the color will recover, which is also the normal reaction of the tissue. The phagocytosis and transport function of macrophages will last for a long time, during which the color of tissues will gradually become lighter. It is suggested that the second treatment should be carried out 1 ~ 2 months after the first treatment. Usually two treatments can achieve satisfactory results.
Possible postoperative appearance:
The treatment site has oozing blood and mild edema. After swelling, there may be itching and tissue hardening when touching, which are normal reactions of tissues. All the bad feelings will disappear completely within two weeks to a month or so, and the length of time varies from person to person.
If the pigment containing iron ions is used in eyebrow tattoo, black iron oxide ions that are not easy to fade will be produced after laser irradiation, and the color will be darker than before eyebrow removal, forming a hard ferrous oxide layer.
It is ok to wash your eyebrows, but washing your eyebrows will generally hurt your hair follicles, and your eyebrows will also get hurt and become less fond of growing.
