Who is not suitable for laser hair removal?

First of all, people with particularly dark skin color are not suitable for laser hair removal. Because laser hair removal uses the absorption of melanin in hair follicles to achieve the effect of hair removal.

Secondly, it is not suitable for laser hair removal under the following conditions:

  1. Patients with a history of keloid.
  2. Those who have infection in the depilation area or have a history of herpes simplex infection.

  2. Do not need to bandage, but apply antibiotic ointment locally;
  3. On the day of treatment, do not wash the treatment site with hot water;
  4. The exposed part should be kept away from light 4 weeks after operation to avoid pigmentation.
