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

are always selected individually.
Why Repeated Shaving Often Becomes a Problem in the Brazilian Area
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.
itching
visible irritation
razor bumps
ingrown hairs
a feeling of coarser new growth
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.
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.
808 nm Diode Laser: The Science Behind Hair Reduction
During treatment, the Quidion 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.
Professional Control for a Delicate Treatment Area
This course used 2 Hz, a low pulse duration, and medium energy, with power adjusted to control the thermal load. The Zemits Quidion supports this individualized treatment approach through several key technologies:
808 nm Diode Laser
Works with the melanin in pigmented hair structures for gradual hair reduction.
Individual Parameter Control
Energy, pulse duration, frequency, and cooling can be adapted to the individual client and treatment plan.
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.
Multi-Layer Cooling
Water cooling + TEC cooling + air cooling + sapphire contact cooling help control the surface temperature and maintain comfort during laser delivery.
The Quidion is a professional system where wavelength, parameters, energy delivery, and cooling work together around a specific treatment strategy.
What Changed Over the Course
After 3 sessions
Ingrown hairs were no longer observed.
After 8 sessions
- 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.
For at-home care, the client was recommended a specialized skincare routine and a moisturizer with SPF.
INDIVIDUALIZED LASER HAIR REDUCTION IN PRACTICE
This case shows how the Quidion works across different treatment plans: Fitzpatrick IV, individually selected parameters, an 8-session course, and a specific concern related to ingrown hairs.
