Laser hair removal is a medical procedure that uses targeted light energy to disable hair follicles at the root, delivering permanent hair reduction across the face and body. Performed under the medical supervision of Michael Nusbaum, MD FACS · FASMBS, at Nusbaum Medical Centers in Cedar Knolls, NJ, our 2026 protocols pair proven laser technology with the clinical safeguards that protect every skin type — the crucial difference between a spa treatment and true, lasting results.

Why Medical Oversight Matters in 2026
Laser hair removal is one of the most requested aesthetic treatments in the country — and one of the most uneven in quality. The device concentrates real energy into your skin, and in the wrong hands, or with the wrong settings for your complexion, that energy can cause burns, blistering, or lasting pigment changes.
That is the fundamental distinction between a walk-in spa and a medically supervised clinic. At Nusbaum Medical Centers, treatments are guided by clinical protocols and physician oversight. Your skin type is formally assessed on the Fitzpatrick scale, settings are matched to your complexion, and a trained provider manages every session. The American Academy of Dermatology emphasizes that laser hair removal is a medical procedure best performed by a qualified, supervised professional — precisely the standard we hold.
Laser hair removal fits naturally within our broader MedSpa & aesthetics offerings, alongside skin treatments like HydraFacial and Morpheus8.
How the Technology Works
The science behind laser hair removal is called selective photothermolysis. The laser emits a specific wavelength of light that is preferentially absorbed by melanin — the pigment in your hair. That light energy converts to heat inside the follicle, damaging the structures responsible for producing new hair while leaving the surrounding skin unharmed.
There are two keys to doing this safely and effectively:
- Wavelength matched to skin tone. Longer-wavelength lasers (such as Nd:YAG) can safely treat darker skin because they target follicle pigment while bypassing pigment in the skin. Choosing correctly is a clinical decision, not a preset button.
- Timing with the hair-growth cycle. Hair grows in phases, and only actively growing (anagen) follicles absorb enough energy to be disabled. Because follicles cycle at different times, a series of sessions is required to reach them all.
This is why most patients need 6 to 8 treatments spaced several weeks apart to achieve smooth, lasting results.
Laser vs. Traditional Methods: The Real Cost
Shaving, waxing, and depilatory creams share one flaw: they treat the surface and nothing else, so the hair is back within days or weeks. They also carry their own recurring costs — ingrown hairs, razor burn, folliculitis, and the endless expense of blades, wax, and appointments.
Laser is different because it addresses the follicle itself. The upfront investment is higher, but the math changes over time:
- Money: A lifetime of razors, wax appointments, and creams typically costs far more than a completed laser series.
- Time: The hours spent shaving and waxing over a lifetime add up to weeks; laser reclaims them.
- Skin health: Ending the cycle of shaving and waxing means fewer ingrown hairs and far less chronic irritation.
For those also dealing with unwanted vessels or spider veins, we offer complementary treatments like Asclera spider-vein removal as part of a complete aesthetic plan.
Preparing for Your Treatment
Good preparation makes laser hair removal safer and more effective. In the weeks before your series, avoid sun exposure and self-tanner — tanned skin raises the risk of pigment changes. Stop plucking, waxing, and threading for about four weeks, since the laser needs an intact follicle to target; shaving, however, is encouraged right before treatment.
Your journey begins with a consultation and often a small test spot to confirm the ideal settings for your skin. Afterward the treated area may feel like a mild sunburn for a day or two; diligent sunscreen protects your results between sessions. Because this is a medical procedure, we review your history, medications, and skin type first — a step consumer home devices simply skip.
