The laser should not be used directly on the cancer or tumor. The laser should not be used on the thyroid gland or on a pregnant uterus. Laser hair removal should generally be avoided while breastfeeding. Your hormones are likely to cause changes in hair growth, which means the procedure may not be as effective as you would have liked. These temporary contraindications allow permanent laser hair removal under certain conditions.
Herpes outbreaks in the treated area (s) must have been treated before permanent laser hair removal. For patients with cold sores, preventive treatment will be prescribed before the laser hair removal session. Allergic reactions such as bullous dermatitis, recent urticaria or recent allergic skin reactions are temporary contraindications, since the skin is in the midst of a reaction or regeneration phase, and this process should not be altered by the action of the laser. A laser class tells you how to protect yourself and others against laser light, so that you don't suffer accidental eye injuries or potential skin damage.
A laser whose power exceeds class 3R (5 mW but does not exceed 500 mW) is called a class 3B laser. In case of accidental direct eye exposure, Class 3B laser light can cause temporary eye damage and, in certain cases, minor skin damage. Therefore, it is advisable to always use the correct eye protection glasses (those supplied with our lasers), even if there is a slight risk that the eye will accidentally light up directly during treatment. It is advisable for the operator and the patient to wear eye protection goggles on a routine basis.
If these are animals, a small towel that covers their eyes during treatment will suffice. Treatment of pregnant patients is not a contraindication. The treatment of pregnant women, both for the mother and the child, is completely harmless. Direct treatment on or against the undeveloped fetus or pointing the laser at an embryo should be avoided, as laser light can inadvertently damage the baby's underdeveloped eyes.
Should any unintended incident or complication occur related to or soon after laser treatment, it's easy to blame laser therapy and, therefore, the burden of proof falls on the therapist. Tattoos, moles and other types of dark skin are not a clinical contraindication, but high-intensity laser light produces “maximum absorption”, often causing local pain. Pregnancy is a medical-legal contraindication for permanent laser hair removal (although no malformations have been observed to date)). In addition to the above contraindication and eye safety precautions, there are several other precautions that must be taken into account during treatment with a cold laser.
There are some health conditions that are generally considered contraindications for laser hair removal. The indications for the use of laser therapy are many, but there are some important contraindications and other points of attention that you should consider.
