Laser Hair Removal in the Brazilian Area: A 10-Session Course for Coarse Hair
The client came in requesting removal of unwanted coarse hair in the Brazilian area. Tetiana Vasyliuk built the course around Fitzpatrick Skin Type I, the hair structure, and individually selected parameters.
10 sessions — and the coarse hair clearly visible in the "before" photo is barely noticeable in the final photo after the course.
Her approach is built on selecting parameters individually, based on skin type, hair structure, and each client's characteristics.
Tetiana Vasyliuk is a laser hair removal specialist with over 5 years of experience, founder of Laser Time studio in Ukraine and Austin, Texas, and a laser hair removal instructor.

Client Profile & Course Parameters
How the Quidion Lite Pro Supported the Result of This Course
In laser hair removal, the result depends largely on how precisely the settings are tailored to the individual client — energy delivery, pulse duration, frequency, and cooling. The Quidion Lite Pro gives the specialist independent control over each of these parameters, so they can be adapted to the individual characteristics of the skin and hair.
In this case, the specialist was working with coarse hair and Fitzpatrick I, so the parameters were selected individually, factoring in hair structure, skin response, and the dynamics of the course. Rather than working from preset modes alone, she could fine-tune every key parameter of the protocol.

QDC Technology: Control of Every Pulse
The multi-layer cooling system works in sync with laser delivery: the skin surface stays at a comfortable temperature while the energy does its work in the follicle. For the sensitive Brazilian area, this is especially important — the specialist can work at the selected parameters throughout the course while maintaining the balance between treatment efficiency and client comfort.
The technology works not only on energy delivery, but on how that energy feels during the actual treatment.

The Quidion Lite Pro combines water cooling, TEC cooling, air cooling, and sapphire contact cooling.
QDC — Quick Dynamic Control — is a Zemits technology developed for more precise control of laser delivery in the Quidion Lite Pro.
It synchronizes pulse timing, energy delivery, and cooling response, helping the system maintain the stable characteristics of consistent, predictable pulses within the parameters selected by the specialist — helping avoid unwanted energy fluctuations and maintaining consistency from treatment to treatment.
For the specialist, this means more controlled, consistent performance from pulse to pulse: the esthetician sets the treatment strategy, and QDC helps the system execute it precisely during the treatment.

Multi-Layer Cooling: Comfort as a Working Tool
Individual Parameters: A Range That Works for the Specialist
This case used 3 Hz, a longer pulse duration, and a customized energy level.
The value wasn't in the individual numbers, but in the Quidion Lite Pro's ability to adapt the parameters precisely to this particular client. The pulse duration was selected for the coarse hair structure, the 3 Hz frequency kept a steady working pace across the entire area, and the specialist set the energy level according to the skin's response and the goals of the treatment.
It's exactly this range of adjustment that lets a professional work with greater precision — accounting not only for the treatment area, but also for hair thickness, phototype, and skin response at every stage of the course.
Professional note: the parameters in this case are not a universal protocol. Settings are always selected individually for each client.

808 nm: Working with Pigmented Hair
The Quidion Lite Pro operates at the 808 nm diode wavelength — widely used in professional hair reduction systems.
The laser energy interacts with the melanin in the hair shaft and creates a controlled thermal effect, which is used to gradually reduce hair regrowth. For coarse, pigmented hair, this gives the specialist a reliable, predictable foundation — the parameter strategy is built around the client.

Technologies Behind Professional Results
What Changed After 10 Sessions
After 10 sessions:
- coarse hair is barely noticeable;
- the surface looks smooth and even;
- there is no noticeable redness or irritated look;
- the client was recommended supportive at-home care and maintenance treatments once a year.
