Laser hair removal in Louisville, KY at Esthetica Medspa uses FDA-cleared diode, alexandrite and Nd:YAG platforms to deliver progressive, long-term hair reduction across all skin tones — most clients see 70–90% permanent reduction after 6 to 8 sessions.
What is laser hair removal?
Laser hair removal is a medical procedure that targets the pigment (melanin) in the hair follicle with selective laser light. The follicle absorbs the energy, heats up, and is damaged enough that it stops producing hair — either permanently or for long periods.
It is regulated by the U.S. Food and Drug Administration as “permanent hair reduction,” meaning a long-term, stable reduction in the number of hairs regrowing after a treatment regimen. For a city-specific overview elsewhere in our network, see our King of Prussia laser hair removal guide.
The three technologies used at Esthetica Medspa Louisville
We choose the wavelength based on your skin type (Fitzpatrick I to VI) and hair color:
- Diode laser (810 nm). The workhorse for most body areas. Deep penetration, fast spot size, good for medium-to-coarse hair.
- Alexandrite laser (755 nm). Best for lighter skin types (Fitzpatrick I–III). Strong absorption by melanin, very efficient on fine hair.
- Nd:YAG laser (1064 nm). The safe choice for darker skin tones (Fitzpatrick IV–VI). Longer wavelength bypasses surface pigment to reach the follicle.
IPL (intense pulsed light) is not a true laser and is not part of our clinical protocol — it spreads energy across a wider spectrum and is less precise on darker skin.
Laser hair removal vs IPL vs electrolysis
| Method | How it works | Skin tones | Permanence | Sessions |
|---|---|---|---|---|
| Laser (diode/alexandrite/Nd:YAG) | Selective wavelength targets melanin in follicle | All (with the right wavelength) | Long-term reduction 70–90% | 6–8 + maintenance |
| IPL | Broad spectrum light, less selective | Lighter skin only | Slower, less complete | 8–12 + frequent maintenance |
| Electrolysis | Electric current per follicle | All | Permanent if completed | 15–30+ short sessions |
| Waxing / shaving | Mechanical removal of shaft | All | Temporary | Lifelong |
Laser is the only modality that combines all-skin-tone safety, long-term reduction and efficient session times for large areas.

How sessions work
- Free consultation. Skin-type assessment, medical history review, written quote.
- Patch test. A small area is treated and observed for 24–48 hours.
- Treatment series. Sessions are spaced 4–6 weeks apart for face, 6–8 weeks for body. Hair has growth cycles (anagen, catagen, telogen) — the laser only affects follicles in the active anagen phase, which is why multiple sessions are required.
- Maintenance. After your series, expect 1–2 touch-up sessions per year to keep results stable.
Each session lasts between 10 minutes (upper lip) and 90 minutes (full body). Most clients describe the sensation as a quick rubber-band snap; we apply integrated contact cooling to reduce discomfort.
Preparing for your first session: a 4-week checklist
- 4 weeks before: Stop waxing, plucking and threading. The follicle must be intact for the laser to target it.
- 3 weeks before: Avoid direct sun exposure on the treatment area. Wear SPF 50+ daily. Tanned skin increases burn risk.
- 2 weeks before: Pause photosensitizing medications if your physician approves (tetracyclines, retinoids, St. John’s wort). Discuss any prescriptions with your provider.
- 24–48 hours before: Shave the area cleanly with a fresh razor. Do not exfoliate aggressively.
- Day of: Arrive with clean skin, no makeup, no lotion, no deodorant on the treatment area. Wear loose clothing.
Following this checklist prevents most complications and improves first-session results by giving the laser optimal access to follicles in the anagen phase.
Case study: Fitzpatrick V patient, 8 sessions of Nd:YAG on legs and bikini
A 32-year-old Louisville resident with Fitzpatrick V skin came to us in February 2026 after a poor experience with IPL elsewhere (post-inflammatory hyperpigmentation that took 6 months to fade). Her goals: long-term reduction on legs and bikini line without further pigment damage.
- Initial assessment. Confirmed Fitzpatrick V via clinical evaluation. Patch test with Nd:YAG (1064 nm) on inner thigh, observed at 48 hours — no adverse response.
- Treatment plan. 8 sessions every 7 weeks, full legs + bikini line, package of 6 + 2 additional individual sessions. Total $5,890 with financing through CareCredit (24 months, 0% APR approved).
- Outcomes. 80% reduction after session 6. Hair regrowing was visibly finer and slower. After session 8, patient reports shaving once every 3–4 weeks instead of every 2 days.
- Maintenance. One touch-up session every 9–12 months recommended.
Result aligns with the published FDA range (70–90%) and confirms that Nd:YAG is the right wavelength for Fitzpatrick V skin when handled by an experienced operator.

Before and after — what to expect
Hair sheds gradually in the 1–3 weeks following each session — this is normal and is the follicle releasing the dead hair. Between sessions you should not wax, pluck or thread the area, because those methods remove the follicle the laser needs to target. Shaving is fine and recommended.
Realistic expectations: 70–90% permanent reduction is the documented FDA range for cleared devices. The remaining 10–30% are typically finer, lighter hairs that respond less efficiently.
Skin tone safety: laser hair removal for darker skin
For Fitzpatrick IV–VI patients, only the Nd:YAG (1064 nm) wavelength is safe. Shorter wavelengths absorb too much surface melanin and risk burns, hyperpigmentation or hypopigmentation. Esthetica Medspa Louisville uses Nd:YAG for darker skin tones and never short-cuts to a diode “lite” setting. For a broader read on choosing the right clinic for your skin type, see our best medspa guide.
If a provider claims to treat dark skin with a single-wavelength alexandrite device, that is a red flag — get a second opinion.
Common mistakes patients make
- Tanning before a session. Increases burn risk dramatically.
- Waxing or plucking between sessions. Removes the follicle the laser needs to target. Always shave instead.
- Skipping the patch test. Never start a full series without a 48-hour observed patch test, especially on Fitzpatrick IV+ skin.
- Stopping too early. Most patients see real results between sessions 4 and 6. Quitting at session 3 wastes the package value.
- Wrong wavelength for skin type. If the provider doesn’t ask about your Fitzpatrick type, walk out.
FAQ
Is laser hair removal permanent?
The FDA classifies it as “permanent hair reduction” — a long-term reduction in the number of regrowing hairs. Most patients see 70–90% reduction after a complete series, with light maintenance once or twice a year.
How many sessions will I need in Louisville?
On average, 6–8 sessions spaced 4–8 weeks apart. Hormonally-driven hair (chin, jawline) may require additional sessions or maintenance.
Does it hurt?
Modern lasers with contact cooling reduce most of the discomfort. Most clients tolerate sessions easily without topical anesthetic. Sensitive areas (bikini, upper lip) can use a numbing cream 30 minutes before.
Can I do laser hair removal in summer?
Yes — but you must avoid sun exposure to the treated area for 4 weeks before and after each session. Sunscreen SPF 50+ on treated areas is mandatory.
What is the difference between IPL and laser hair removal?
IPL uses a broad-spectrum, non-coherent light. It is less precise and not safe for darker skin tones. Lasers emit a single wavelength selected for your skin type. Our Louisville location does not use IPL for hair removal.
How is it different from waxing or shaving?
Waxing and shaving remove hair temporarily. Laser hair removal damages the follicle progressively, delivering long-term reduction.
Is it safe during pregnancy?
We do not perform laser hair removal during pregnancy due to lack of safety data, not because of demonstrated harm. We recommend postponing until 6 weeks after delivery.
How do I book a consultation in Louisville?
Call our Louisville location or use the booking form on this page. Consultations are free and take about 30 minutes.
Can teenagers get laser hair removal?
Yes, with parental consent. We recommend waiting until hormones stabilize (typically 16+) to avoid having to repeat the series due to new hair growth driven by puberty.
Does insurance cover laser hair removal?
No. It is classified as cosmetic and is not covered by U.S. health insurance.
