Picosecond Laser Removal of Tattoos

What are the hazards of laser hair removal?

Nowadays, girls love beauty. Many girls often choose laser hair removal to remove excess and unsightly hair in order to have white skin. However, many people are worried that laser hair removal is harmful to the body and dare not use it. Is laser hair removal harmful?

The principle of laser hair removal is that by reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the surface of the skin to the root hair follicle of the hair. The light energy is absorbed and transformed into heat energy that destroys the hair follicle tissue, so as to make the hair lose the ability of regeneration. It is a safe and long-term hair removal technology.

In the process of laser hair removal, because the skin basically does not absorb laser energy, even if it does, it is very small. In addition, while laser hair removal, there will be corresponding devices to cool and protect the skin, which will not damage the skin.

Therefore, in theory, laser hair removal will not cause harm.

However, improper laser hair removal or improper postoperative care of the beauty seeker may lead to the following three side effects:

  1. The laser may cause damage to skin melanin, especially those with darker skin, and then form spots.
  2. After treatment, there may be red fever. The skin may harden within two or three days, and there may be traces of treatment left on the skin.
  3. If the laser energy used is too strong, it may burn the skin and leave scars.
  4. After treatment, some people’s skin, especially after laser irradiation, will have some brown thin scabs on local skin. Don’t tear them off by force. They will fall off in about a week.
