Laser Hair Removal for Ingrown-Prone Skin: an 8-Session Course for Fitzpatrick Skin Type IV

Laser Hair Removal for Ingrown-Prone Skin: an 8-Session Course for Fitzpatrick Skin Type IV
The client came in requesting laser hair removal due to unwanted hair, ingrown hairs, and an irritated-looking skin.


Tetiana Vasyliuk built the course on the Zemits Quidion Lite Pro with parameters individually adapted for Fitzpatrick Skin Type IV.


8 sessions — and the ingrown hairs clearly visible before the course were no longer observed, while the skin in the Brazilian area looked smoother, softer, and calmer.
Her approach is built on selecting parameters individually, based on skin type, hair structure, and each client's characteristics.

Client Profile & Course Parameters
Why Repeated Shaving Often Becomes a Problem in the Brazilian Area
After shaving, the hair is cut close to the skin's surface. As it grows back, this can be accompanied by:
That's why the professional request here often goes beyond a simple "remove the hair." The client wants less regrowth, less need for shaving, and a more comfortable-looking skin condition between treatments.


In the Brazilian area, this is especially noticeable because shaving is often repeated regularly, and the area itself is in constant contact with underwear and exposed to friction.

The Brazilian area is regularly exposed to friction, close shaving, and repeated hair regrowth. Because of this, for many clients shaving becomes not just a routine procedure, but a source of constant discomfort.
808 nm Diode Laser: The Science Behind Hair Reduction
During treatment, the Quidion Lite Pro directs 808 nm laser energy at the pigmented structures of the hair. Melanin absorbs this energy, which is then converted into localized heat.

This heat affects the follicular structures involved in forming new hair, so with each treatment, the hair's capacity for regrowth gradually decreases.


Laser pulse → melanin absorbs energy → localized heat → follicular response → less regrowth over time
What Changed Over the Course
Professional Control for a Delicate Treatment Area
For at-home care, the client was recommended a specialized skincare routine and a moisturizer with SPF
The Quidion Lite Pro is a professional system where wavelength, parameters, energy delivery, and cooling work together around a specific treatment strategy.
This course used 2 Hz, a low pulse duration, and medium energy, with power adjusted to control the thermal load.
The Zemits Quidion Lite Pro supports this individualized treatment approach through several key technologies:
Multi-Layer Cooling
Water cooling + TEC cooling + air cooling + sapphire contact cooling help control the surface temperature and maintain comfort during laser delivery.



  • hair is barely noticeable;
  • ingrown hairs were no longer observed;
  • the skin looks smoother and softer;
  • the irritated, inflamed-looking condition of the area became significantly less noticeable.
After 8 sessions
After 3 sessions
Ingrown hairs were no longer observed
QDC Technology
QDC — Quick Dynamic Control — is Zemits' proprietary technology that coordinates pulse timing, energy delivery, and cooling response, helping maintain predictable performance from pulse to pulse without unwanted energy fluctuations.


Individual Parameter Control
Energy, pulse duration, frequency, and cooling can be adapted to the individual client and treatment plan.
808 nm Diode Laser
Works with the melanin in pigmented hair structures for gradual hair reduction.
