The Wheal "TikTok Show"

What are hives and how do they arise?

A medical report based on some TikTok posts without any technical substance or knowledge.

How does it work?

They are looking for a girl who will read a script and has absolutely no idea about hair removal and medical procedures. Shake your body a little, smile a little, and you have a video that is designed to scare people off.

Of course, the professional beauticians laugh about it,
but all startups are deterred by this.

For this reason, we have created medical documentation of its effectiveness.

NISV Training Materials : Hives, also known as urticaria, are raised, itchy skin rashes that can often occur in response to laser hair removal treatment. These hives are caused by an inflammatory reaction of the skin. There are several mechanisms by which they can be caused:

Histamine release: Laser treatment can trigger the release of histamine from the mast cells in the skin. Histamine is a mediator that causes inflammation and swelling, resulting in the formation of hives.

Thermal reaction: The laser energy is converted into heat, which destroys the hair follicles. This heat can trigger a local inflammatory reaction in the skin, which can also lead to the formation of hives.

Mechanical irritation: The application of the laser and the associated manipulation of the skin can cause mechanical irritation that triggers an inflammatory reaction.

Are hives primary features of successful treatment?

No, hives are not a primary feature of a successful laser hair removal treatment. Rather, they are a temporary side effect that may occur in some patients. The success of laser hair removal is determined by other factors:

Reduction in hair density: A successful treatment is shown by a significant reduction in hair density in the treated area.

Sustainability of results: The long-term success is shown in the sustained reduction in hair growth after several treatments.

Minimal side effects: A successful treatment should have minimal and temporary side effects, including skin irritation that resolves quickly.

Other causes of hives:

Hives can also be caused by other factors that are not directly related to laser treatment:

Allergic reactions: Patients may have allergic reactions to the gel used during treatment or to other topical products.

Skin sensitivity: Some patients have more sensitive skin that reacts more strongly to laser treatment.

Improper use of the laser: Incorrect laser setting or improper use can result in an excessive thermal reaction that causes hives.


Hives are a possible side effect of laser hair removal, but they are not a sign of the success of the treatment. They usually result from the release of histamine and a local inflammatory reaction of the skin. Successful laser hair removal is characterized by the effective and lasting reduction of hair growth and by minimally invasive side effects.
