The 'In Motion' process is a specific application technique designed to revolutionize how energy is delivered during Super Hair Removal (SHR) treatments. Rather than holding the device stationary and delivering a single high-intensity shot, the practitioner continuously slides the handpiece over the skin in smooth, sweeping movements. This dynamic method utilizes a high repetition rate of low-energy pulses to gradually heat the treatment area, ensuring uniform coverage without the sharp pain associated with traditional lasers.
The Core Concept: By replacing the traditional "blast and move" method with a continuous gliding motion, the 'In Motion' technique achieves permanent hair reduction through gradual heat accumulation. This approach targets both the hair follicle and the stem cells, making the procedure significantly safer and more comfortable than stationary application methods.
The Mechanics of the Gliding Technique
Continuous Movement vs. Stationary Stamping
In traditional laser or IPL (Intense Pulsed Light) therapies, the operator uses a "stamping" method: place the device, fire a high-energy pulse, lift, and move to the next spot.
The 'In Motion' process eliminates this stop-and-start approach. The practitioner glides the applicator over the skin, often passing over the same area 6 to 10 times. This ensures that energy is distributed evenly across the entire treatment zone, preventing the "checkerboard" effect of missed spots common in stationary treatments.
Gradual Heating of the Dermis
The most critical technical distinction of this process is how it handles heat. Instead of a sudden spike in temperature that shocks the nerve endings, 'In Motion' uses low fluence (energy) at high frequencies.
This creates a cumulative effect. The dermis is gradually heated to a target temperature of approximately 48 degrees Celsius. This temperature is sufficient to damage the hair follicle and prevent regrowth, but it is reached gently over a longer period (roughly 90 seconds per area) rather than instantly.
Dual Targeting Strategy
This process does not just burn the hair shaft. The technique is designed to split its effectiveness.
Approximately 50% of the energy targets the existing hair, while the other 50% is absorbed by the stem cells responsible for producing new hair. By targeting the stem cells with consistent, lower-intensity heat, the process effectively terminates hair growth while minimizing trauma to the surrounding tissue.
Why 'In Motion' Changes the Patient Experience
A Shift in Pain Perception
Because the energy is delivered via low-power pulses rather than a single high-power blast, the sensation is drastically different.
Patients rarely feel the "rubber band snap" associated with traditional lasers. Instead, the sensation is typically described as a mild warming of the skin. This makes the treatment virtually pain-free and viable for sensitive areas where traditional laser might be too painful.
Enhanced Safety for Melanin-Rich Skin
Traditional lasers target melanin aggressively, which poses a burn risk for darker skin tones where the skin competes with the hair for energy absorption.
The 'In Motion' technique bypasses this risk through its gradual heating profile. By keeping the energy intensity lower and moving constantly, the skin does not absorb dangerous levels of heat in a single moment. This makes the process safer for a wider variety of skin types, reducing the risk of burns, redness, and pigmentation issues.
Understanding the Trade-offs
The Necessity of Repetition
While the 'In Motion' process reduces pain, it changes the workflow of the session. The technician cannot simply zap a spot once and move on.
Success relies on the cumulative buildup of heat. If the practitioner moves too quickly or does not pass over the area enough times (typically 6 to 10 passes), the follicle may not reach the temperature required for permanent destruction. The technique requires a diligent and active operator to be effective.
Perception of Efficacy
Because the treatment is often painless, some patients may mistakenly believe it is not working.
Patients accustomed to the sharp sting of traditional lasers often associate pain with effectiveness. It is important to understand that the photothermolysis effect (destruction by heat) is still occurring, just through a different, more gradual thermodynamic pathway.
Making the Right Choice for Your Goals
The 'In Motion' process represents a shift from aggressive energy delivery to progressive heat accumulation. Here is how to decide if this method aligns with your needs:
- If your primary focus is Pain Management: The 'In Motion' method is the superior choice, as it eliminates the sharp "snapping" sensation of traditional lasers in favor of a warming sensation.
- If your primary focus is Safety on Darker Skin: This technique is highly recommended because the low-energy, gradual heating approach significantly minimizes the risk of burns and hyperpigmentation.
- If your primary focus is Treatment Speed: While the handpiece moves constantly, the total time may be similar to traditional methods due to the need for multiple passes; however, the lack of "recovery time" between painful snaps can make the overall session feel faster.
Ultimately, the 'In Motion' process offers a modern alternative that prioritizes patient comfort and safety without sacrificing the efficacy of permanent hair reduction.
