Key takeaways
- FDA-cleared lasers claim permanent hair reduction — fewer hairs regrowing — not the removal of every hair.
- It works best on dark hair; the AAD says dark skin and light hair can be treated, but very carefully.
- Treatment is a series: the AAD says to expect a 10% to 25% reduction in hair after the first session.
- Common side effects — discomfort, swelling, redness — last 1 to 3 days; some skin color changes are permanent.
- Insurance does not cover it, so get a written plan that states sessions and maintenance costs.
What is laser hair removal and how does it work?
Laser hair removal is a light-based cosmetic treatment that targets the pigment (melanin) inside the hair follicle.
That targeting is both the trick and the limitation: the American Academy of Dermatology (AAD) notes the treatment works best on dark-colored hair, because the laser targets pigment.
Hair-removal lasers are medical devices, cleared by the FDA through its 510(k) pathway rather than approved like a prescription drug.
Their cleared claim is permanent hair reduction, which FDA-cleared labeling defines as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9 and 12 months after completing a treatment regimen.
The wording matters: it does not mean all hair is gone for good.
Several laser types do this work.
Common devices use alexandrite (755 nm), Nd:YAG (1064 nm) or diode (for example 810 nm) lasers, and some machines combine two wavelengths — Candela's GentleMax Pro Plus, for example, pairs a 755 nm alexandrite laser with a 1064 nm Nd:YAG laser in one system.
The wavelength matters for which device suits which skin tone, as the candidate section below explains.
What does laser hair removal treat, and who is a good candidate (and who is not)?
The AAD lists the areas laser hair removal can treat as the armpits, back, bikini area, chest, face (especially the upper lip and chin), legs, neck and shoulders.
For facial areas, see laser hair removal on the face.
The profile that responds best is light skin with dark hair.
The AAD says advances now let people with dark skin — and people with light hair and light skin — be treated too, but that in these patients the treatment must be performed very carefully.
Device labels cut both ways here.
The cleared labeling for several hair-removal lasers — Candela GentleMax, the Alma Soprano Titanium diode and Lumenis LightSheer among them — lists use on all Fitzpatrick skin types I–VI, including tanned skin.
A label alone does not make every setting or device equally safe for dark skin.
The published evidence agrees with that caution.
A 2020 meta-analysis of 12 comparative trials in Fitzpatrick skin types III–VI found long-pulsed Nd:YAG laser was associated with less post-inflammatory hyperpigmentation than IPL, while alexandrite was superior to IPL for hair-count reduction; overall outcomes across the devices were broadly similar.
Before treatment, the AAD says to tell your provider about a tendency to scar or form keloids, a recent tan, cold sore or genital herpes outbreaks, and isotretinoin or any other medicines you take.
Its preparation guidance also says not to tan or use sunless tanners, and to use broad-spectrum sunscreen of SPF 30 or higher.
There is no single not-a-candidate list on this page, because the sources we reviewed do not give one; the disclosures above are what the AAD says to raise with a provider before treatment.
One gap to name plainly: we could not confirm from these sources how laser hair removal is handled in pregnancy or while breastfeeding, so put that question directly to a licensed provider.
How much does laser hair removal cost?
Laser hair removal has no single price list.
ASPS says laser hair removal prices may be based on the expertise and qualifications of the person performing the procedure, the type of procedure used, the time and effort the treatment requires and the geographic location of the office.
Time follows the area — the AAD notes an upper lip takes minutes, while large areas like the back or legs can take more than an hour.
Chain headline prices are promotional and package-based: LaserAway's own pricing page, read on October 16, 2026, was advertising 70% off select laser hair removal packages under its offer terms.
The American Society of Plastic Surgeons (ASPS) puts the average cost of laser skin treatments like laser hair removal at $697, according to its latest statistics.
Read that figure carefully: ASPS says it excludes other related expenses, the page does not say whether it is per session, and it is a plastic-surgeon fee rather than a med spa price.
One honest gap: we could not confirm a national average price per area for laser hair removal — our research found no tier-1 or tier-2 source that publishes one.
Local quotes are the numbers that matter, so ask providers for a written price for your areas that states how many sessions it assumes and what later maintenance sessions would cost.
Budget for the whole course rather than one visit: the AAD says insurance does not cover laser hair removal, and that keeping an area free of hair can require maintenance laser treatments after the initial series.

How many sessions do you need and how long do results last?
A first session gives a first result: the AAD says you can expect a 10% to 25% reduction in hair after the first treatment.
Sessions are spaced weeks apart, and the AAD says most patients can have a session once every 4 to 6 weeks.
On the count, the AAD's own pages give two figures: its FAQ says most patients need 2 to 6 laser treatments, while its overview says removing the unwanted hair can take 6 sessions or more.
Hold both — the count varies with the area, the hair and the device, which is also why package deals deserve scrutiny before you buy.
After a course, the AAD says most patients remain hair-free for months or even years, and that hair which regrows tends to be less noticeable — finer and lighter — though maintenance treatments may be needed to keep the area clear.
For more on results over time, see how long laser hair removal lasts.
The AAD's overview goes further, calling laser hair removal permanent on most areas of the body after treatment, while noting that because of hormones it is not permanent on a woman's face.
The FDA's wording is the more careful yardstick for any promise a clinic makes: cleared devices claim a long-term, stable reduction in regrowing hairs, not the removal of all hair.
The measured evidence sits below complete clearance.
A 2022 systematic review of 5 randomized trials (223 patients), each with follow-up of at least one full hair-growth cycle, found average long-term reduction of 30–73.6% for Nd:YAG, 35–84.3% for alexandrite, 32.5–69.2% for diode and 27–52.7% for IPL — greatest on the legs and lowest on the face.
Average long-term hair reduction by device
| Device | Long-term reduction |
|---|---|
| Nd:YAG | 30–73.6% |
| Alexandrite | 35–84.3% |
| Diode | 32.5–69.2% |
| IPL | 27–52.7% |
FDA-cleared labeling defines permanent hair reduction as the long-term, stable reduction in the number of hairs regrowing, measured at 6, 9 and 12 months after a treatment regimen. It counts what grows back — it is not a promise that every hair is gone.
Does laser hair removal hurt, and what is the downtime?
The pulses often feel like warm pinpricks or a rubber band snapping against the skin, in the AAD's description.
A numbing gel takes about 30 to 60 minutes to work.
Session length follows the area: minutes for an upper lip, more than an hour for large areas such as the back or legs.
Downtime is minimal in the AAD's account: laser hair removal generally requires no real downtime, treated skin turns red and swollen right afterward — often like a mild sunburn — and most people return to everyday activities.
Devices differ in comfort, too.
A 2023 review of laser and IPL hair removal reports pain varies by device: IPL scored less painful than alexandrite but more than diode, and Nd:YAG scored highest for pain.
What are the side effects and risks of laser hair removal?
The everyday effects are minor: discomfort, swelling and redness that last 1 to 3 days, in the AAD's summary.
Rarer effects include blistering, cold sore outbreaks, infection, scarring and skin lightening or darkening — and the AAD notes some skin color changes are permanent.
That last one is why the device-and-operator questions in the provider section below belong before you book, not after.
One risk surprises people: paradoxical hypertrichosis, meaning new or thicker hair growth after laser or IPL hair removal.
A 2021 meta-analysis of 22 studies and 9,733 patients found it in a pooled 3% of patients, mostly on the face or neck — it appeared in just 0.08% of non-face or neck cases — and in 3 of 4 studies it improved with continued treatment.
Rates are not uniform: a 2025 prospective study of women having alexandrite laser for facial hair in Jordan found it in 16.2%, with higher rates linked to PCOS, irregular periods, family history of hirsutism, Fitzpatrick types III–IV and lack of regular sunblock.
A 2023 review of laser and IPL hair removal reports eye injuries — uveitis, iris damage, pupil distortion, cataract — and skin complications including burns, pigment change, paradoxical hair growth and herpes flares. Most were linked to skin type, body area, device and settings, and the review says most are avoidable with proper training and eye protection. Ask how your eyes and skin will be protected, and contact your provider about blistering, color change or any eye symptom.
Laser hair removal vs alternatives: which is right for you?
The other light-based option is IPL, intense pulsed light.
IPL is not a laser: ASPS defines it as a non-laser light treatment that emits multiple wavelengths, whose energy is absorbed by target cells and converted to heat, aimed at pigment, blood vessels and hair follicles.
Devices such as the Lumenis Stellar M22 are FDA-cleared for permanent hair reduction, so this is a real competitor rather than a lesser category.
Two evidence points separate them.
In the 2020 meta-analysis in Fitzpatrick types III–VI, alexandrite was superior to IPL for hair-count reduction, and Nd:YAG caused less post-inflammatory hyperpigmentation than IPL.
The labels differ too: the Stellar M22's hair-reduction clearance covers Fitzpatrick skin types I–V, not VI, where several laser labels list I–VI.
Lasers
- Alexandrite was superior to IPL for hair-count reduction in Fitzpatrick types III–VI
- Nd:YAG caused less post-inflammatory hyperpigmentation than IPL
- Several laser labels list Fitzpatrick skin types I–VI
IPL
- Not a laser: emits multiple wavelengths of light
- Aimed at pigment, blood vessels and hair follicles
- Stellar M22 hair-reduction clearance covers Fitzpatrick types I–V, not VI
Against non-light methods — waxing, threading, electrolysis, prescription creams — we did not find a rigorous head-to-head comparison on cost or long-term results in the sources for this page, so we will not invent one.
What the evidence does support is a fit profile.
Lasers target melanin and work best on dark hair; light hair is the harder case — the AAD says people with light hair and light skin can be treated, but very carefully; and a woman's face is the area the AAD specifically flags as not permanent, because of hormones.
How do you choose a laser hair removal provider near you?
Once you have local options, the vetting is concrete.
Ask which laser the clinic would use for your skin tone and hair color — alexandrite, diode or Nd:YAG — and why.
In the 2020 meta-analysis above, the devices differed: Nd:YAG caused less post-inflammatory hyperpigmentation than IPL and alexandrite reduced more hair than IPL, even though overall outcomes were broadly similar.
Ask who operates the laser and what training they hold.
The 2023 adverse-event review ties most complications to skin type, body area, device and settings, and says most are avoidable with proper training and eye protection — so training and protective eyewear are direct, fair questions.
There is also no single federal legal definition of a med spa: whether one is regulated as a medical practice, and who may own it, is determined by each state's rules — so ask what license the person operating the laser holds in your state.
Use the consultation to hear the AAD's screening list read back to you: its preparation guidance tells patients to disclose a tendency to scar or form keloids, a recent tan, cold sore or genital herpes outbreaks, and medicines including isotretinoin.
Expect those questions in a thorough consultation, and volunteer them if they never come up.
On price, get the plan in writing: the price, the package terms, the areas included, the number of sessions assumed, and the cost of later maintenance sessions.
ASPS's price drivers — operator expertise, procedure type, time and effort, and location — are one reason two clinics can quote differently.
Read the marketing the way the FDA's wording reads: a promise of permanent removal is a red flag, because the cleared claim across these devices is permanent hair reduction — fewer hairs regrowing over the long term — not the removal of every hair.
A clinic promising more than reduction is promising more than the evidence holds.
Frequently asked questions
Is laser hair removal permanent?
The cleared wording is permanent hair reduction: a long-term, stable reduction in the number of hairs regrowing, measured at 6, 9 and 12 months after a treatment regimen.
It is not the removal of every hair.
The AAD says most patients remain hair-free for months or even years, with regrowth that tends to be finer and lighter, and it notes that because of hormones the results are not permanent on a woman's face.
Does laser hair removal hurt?
The AAD says the pulses often feel like warm pinpricks or a rubber band snapping against the skin, and a numbing gel needs 30 to 60 minutes to take effect beforehand.
A 2023 review found pain varies by device: IPL was less painful than alexandrite but more than diode, and Nd:YAG scored highest.
Treated skin is red and swollen afterward, often like a mild sunburn, before it settles.
Does insurance cover laser hair removal?
No — the AAD says insurance does not cover laser hair removal.
ASPS puts the average cost of laser skin treatments like laser hair removal at $697, excluding related expenses, and that figure is a plastic-surgeon fee rather than a med spa price.
Because a course means several sessions plus possible maintenance, ask providers for the total cost of your plan in writing.
Can dark skin tones get laser hair removal?
Yes.
The AAD says advances now let people with dark skin be treated, but that the treatment must be performed very carefully.
Several laser labels list all Fitzpatrick skin types I–VI, and a 2020 meta-analysis in skin types III–VI found Nd:YAG caused less post-inflammatory hyperpigmentation than IPL.
Ask which wavelength the clinic would use for your skin, and why.
How long does a laser hair removal session take?
It depends on the area.
The AAD says an upper lip takes minutes while large areas such as the back or legs can take more than an hour, and a numbing gel adds 30 to 60 minutes before treatment.
The AAD says most patients can space sessions 4 to 6 weeks apart, its FAQ gives 2 to 6 treatments, and its overview says removing the hair can take 6 sessions or more.
