The average American woman will spend $10,000 to $23,000 on hair removal over her lifetime—razor cartridges, shaving cream, waxing appointments, ingrown-hair treatments. Men who groom regularly aren't far behind. The American Academy of Dermatology ranks laser hair removal as one of the most common nonsurgical cosmetic procedures in the country, and the math explains why.
At Millennium Skin and Laser in Clifton, NJ, we've performed thousands of treatments over 25 years. Here's an honest breakdown of the science, the costs, and what actually happens to your skin.
Is Laser Hair Removal Actually Permanent?
Let's get the terminology right. The FDA classifies laser hair removal as permanent hair reduction, not permanent removal. In practice, most clients see 80–90% less hair growth after completing their full treatment series. The hair that does come back tends to be finer, lighter, and slower-growing.
You'll likely need a maintenance session once or twice a year to catch dormant follicles that cycle into active growth. But compared to shaving every two or three days, or waxing every four to six weeks? The difference is dramatic.
The Science: How Laser Hair Removal Actually Works
Laser hair removal relies on selective photothermolysis, first described by Anderson and Parrish at Harvard in 1983: a specific wavelength of light gets absorbed by a specific target (a chromophore) without damaging the tissue around it.
In hair removal, the chromophore is melanin—the pigment in your hair follicle. When the laser pulse hits the follicle, melanin absorbs the energy and converts it to heat, damaging the dermal papilla (which feeds the hair) and the bulge region (where stem cells regenerate the hair). Damage both, and the follicle can't produce new hair.
This is why:
- Dark hair responds best — More melanin means stronger laser absorption
- Light, white, or gray hair doesn't respond — Not enough pigment to absorb the laser energy
- Darker skin needs the right laser — Some wavelengths can't tell the difference between melanin in skin and melanin in the follicle, which causes burns. Read our guide to laser treatments for dark skin for a full explanation
A 2013 study by Gan and Graber in the Journal of Clinical and Aesthetic Dermatology confirmed that the Nd:YAG 1064nm wavelength is the safest option for darker skin tones because its longer wavelength penetrates deeper past the epidermis, bypassing surface melanin to reach the follicle.
Why We Use the Aerolase Neo Elite
Not all lasers are equal. The Aerolase Neo Elite uses a 1064nm Nd:YAG laser with a 650-microsecond pulse duration. That pulse speed is the key: older alexandrite lasers fire at roughly 3 milliseconds, diode lasers at around 30 milliseconds. The Aerolase fires at 0.65 milliseconds—about 5 times faster than an alexandrite and 46 times faster than a diode.
A shorter pulse delivers energy to the follicle before heat spreads into surrounding skin. Less thermal spread means less pain, less redness, and a far lower burn risk—especially on darker skin tones (Fitzpatrick IV–VI).
For our clients across Northern NJ's diverse communities—Clifton, Paterson, Passaic, Garfield, and surrounding areas—this isn't a nice-to-have. It's the reason we chose this specific machine.
Treatment Areas: Realistic Session Counts and Expectations
Face (Upper Lip, Chin, Sideburns)
- Session time: 10–15 minutes
- Sessions needed: 6–10 (facial hair is hormonal and stubborn; women with PCOS often need the higher end)
- Frequency: Every 4 weeks
- What to expect: Upper lip is the most sensitive spot for most people. The Aerolase makes it tolerable without numbing cream for the majority of clients.
Underarms
- Session time: 10 minutes
- Sessions needed: 4–6
- Frequency: Every 4–6 weeks
- What to expect: One of the fastest-responding areas. Many clients see significant thinning after just two sessions.
Bikini Line vs. Full Brazilian
- Bikini line: 15 minutes, 4–6 sessions
- Full Brazilian: 20–30 minutes, 6–8 sessions
- Frequency: Every 4–6 weeks
- What to expect: The first Brazilian session is the most uncomfortable; each session after that gets easier as there's less hair to treat. We provide disposable underwear and keep the treatment room completely private.
Full Legs
- Session time: 45–60 minutes
- Sessions needed: 6–8
- Frequency: Every 6–8 weeks (leg hair has a longer growth cycle)
- What to expect: Lower legs respond faster than thighs. Coarse, dark hair on the calves often shows results first.
Back (Men)
- Session time: 30–45 minutes
- Sessions needed: 6–8
- Frequency: Every 6–8 weeks
- What to expect: Back hair is typically thick and deep-rooted, so plan for the full 8 sessions. Results are worth it—no more scheduling around pool season.

How Much Does Laser Hair Removal Cost in NJ?
Pricing depends on the treatment area and provider. At Millennium Skin and Laser, we price about 30% below what most Bergen County and Manhattan clinics charge. Here's a general range:
- Small areas (upper lip, chin): $75–$150 per session
- Medium areas (underarms, bikini): $150–$250 per session
- Large areas (full legs, back): $300–$500 per session
We offer package discounts when you prepay for a full treatment series. Schedule a free consultation for exact pricing based on your specific needs.
The Real Cost Comparison
The average woman spends $10,000–$11,000 on razors and shaving cream over a lifetime. Regular Brazilian waxing at $60–$75 every 4–6 weeks adds up to $23,000+ over 30 years.
Laser hair removal for full Brazilian plus underarms plus lower legs runs $3,000–$5,000 total. Add a maintenance session once or twice a year ($75–$150 each), and you're spending a fraction of the lifetime razor or wax budget—before factoring in time savings.
How to Prepare for Your Appointment
Two weeks before: Stop waxing, plucking, or threading (the follicle must be intact for the laser to target it—shaving is fine). Avoid sun exposure and tanning beds. Stop retinoids on the treatment area.
24 hours before: Shave the treatment area to stubble. Skip lotions, deodorants, and makeup on the area. Wear loose, comfortable clothing.
Common Mistakes I See Between Sessions
After 25 years, these are the errors that slow people's results:
Waxing or plucking between sessions. The number one mistake. The laser needs an intact follicle. Shaving is fine—it cuts hair at the surface—but waxing pulls the follicle out, leaving nothing for the laser to target at your next visit.
Spacing sessions too far apart. Hair grows in cycles (anagen, catagen, telogen). The laser only hits hairs in the active anagen phase. Correct spacing catches each wave of growth. Wait too long and you miss the window.
Sun exposure before treatment. A tan increases surface melanin, making it harder for the laser to distinguish your skin from the hair follicle. Higher burn risk, weaker results. If you get a tan, tell us—we'll adjust settings or reschedule.
Expecting results after one session. Your first session only targets the 20–25% of hairs in active growth. The rest are dormant. Full results take 6–8 sessions over several months.
What It Feels Like, and What Happens After
Most clients describe the Aerolase as a warm snap—less intense than a wax strip. The 650-microsecond pulse dissipates heat before you register much pain. Most don't need numbing cream.
Afterward, expect mild redness for a few hours and possibly tiny bumps around follicles (normal, fades in a day or two). For 48 hours, avoid hot showers, saunas, exercise, pools, and sun. Over the next 1–3 weeks, treated hairs will shed—they're falling out, not growing back. You can shave between sessions. Use SPF 30+ on treated areas.
Who Shouldn't Get Laser Hair Removal
- White, gray, or blonde hair — Not enough pigment for the laser to target
- Active tans — Increased burn risk; wait 2–4 weeks
- Pregnancy — We recommend waiting until after delivery
- Certain medications — Some antibiotics and isotretinoin (Accutane) increase photosensitivity
We review your full medical history during your consultation to confirm you're a good candidate.
Frequently Asked Questions
How many sessions will I actually need?
Most clients need 6–8 sessions. Hair grows in three phases, and the laser only affects hair in the active growth (anagen) phase. Spacing sessions 4–8 weeks apart (depending on body area) lets us catch each cycle.
Does hair grow back years later?
Some clients see minor regrowth after hormonal changes—pregnancy, menopause, PCOS. A maintenance session once or twice a year takes care of it.
Can I do laser hair removal on tattooed skin?
No. The laser would damage the tattoo ink and potentially burn your skin. We treat around tattoos but not over them.
Is it safe for dark skin?
Yes—with the right laser. Our Aerolase Neo Elite's 1064nm wavelength is specifically the safest for darker skin tones, backed by peer-reviewed research. We also welcome clients from all backgrounds—learn more about our LGBTQ-friendly med spa and our gender affirming laser hair removal services.
