The underarms may be the smallest area most people treat with laser, but the quality-of-life impact is enormous. No more nightly shaving before a morning meeting. No more stubble by noon. No more irritation from repeated razor passes over sensitive skin. For thousands of New Yorkers, underarm laser hair removal has quietly become one of the best decisions they've made for their daily routine. At Laser and Me, our NYC medical spa at 347 5th Avenue, Suite 803A, underarm laser hair removal is one of our fastest and most requested treatments.
How Underarm Laser Hair Removal Works
Underarm hair removal by laser operates on the same fundamental principle as all laser hair removal: precise light energy is delivered into the hair follicle, where it is absorbed by melanin (the pigment in the hair shaft), converts to heat, and thermally disables the follicle from producing future hair growth.
What makes the underarm area particularly well-suited for laser treatment is that axillary hair tends to be dark, coarse, and densely packed, all characteristics that maximize laser effectiveness. The concentrated melanin in underarm follicles means each pulse of laser energy has a clear, high-contrast target to lock onto.
At Laser and Me, we use the Cynosure Elite+ system with either the 755nm Alexandrite wavelength (for lighter skin tones, Fitzpatrick I-III) or the 1064nm Nd:YAG wavelength (for medium to dark skin tones, Fitzpatrick IV-VI). Pavel Atamas assesses your skin tone before every session and calibrates the device accordingly. The system's integrated Dynamic Cooling Device chills the skin surface immediately before each laser pulse, protecting the epidermis and significantly reducing sensation during treatment.
A single underarm session at Laser and Me takes approximately 8-12 minutes for both underarms combined, making it one of the easiest treatments to fit into a busy Manhattan workday.
Who Is a Good Candidate for Underarm Laser Hair Removal?
Underarm laser hair removal at Laser and Me is appropriate for virtually all adults who want long-term reduction of underarm hair. Strong candidates include people with dark underarm hair and any skin tone. The Cynosure Elite+'s dual-wavelength capability makes safe treatment possible across Fitzpatrick skin types I through VI.
Anyone experiencing ingrown hairs or razor irritation is also an excellent candidate. The underarm area is particularly prone to ingrown hairs and contact dermatitis from frequent shaving. Laser hair removal eliminates both the hair and the need for daily shaving, resolving these issues for most clients within the first few sessions.
Clients who wax regularly will also benefit significantly. Waxing is effective but temporary, expensive over time, and irritating to sensitive underarm skin. Laser hair removal replaces the waxing cycle with permanent reduction.
Clients with very light, blonde, gray, or red underarm hair may see limited results since laser targets melanin. An honest assessment at consultation will clarify your candidacy.
What to Expect: Sessions, Timeline, and Results
For the underarm area, most clients achieve 80-90% permanent hair reduction after 6-8 sessions spaced 4-6 weeks apart. The spacing is important. It allows time for treated follicles to shed and for the next cycle of active-growth follicles to present themselves for the subsequent session.
Sessions 1-2: Treated hairs begin shedding 1-3 weeks after the first session. The underarm may appear stubbly during the shed phase. This is not regrowth; it's the treated shaft being expelled. Results from the first session alone may feel modest. That's normal.
Sessions 3-4: Significant thinning is typically visible by this point. Regrowth is noticeably finer and slower. Many clients stop daily shaving during this phase.
Sessions 5-8: For most clients, underarm hair is dramatically reduced, sparse, fine, and in many cases entirely absent between sessions. This is the phase where the quality-of-life change becomes undeniable.
Most clients rate underarm laser treatment as very tolerable. The underarm is moderately sensitive, but sessions are so brief, under 12 minutes, that any discomfort is short-lived. Downtime is essentially none. You may notice mild redness or slight puffiness in the underarm for a few hours.
The Long-Term Value: Laser vs. Daily Shaving in NYC
Consider the math. If you shave your underarms six days a week, that's roughly 300 shaving events per year. A quality razor blade lasts about a week, plus shaving cream, plus time.
The cumulative cost of razors, shaving cream, and ingrown hair treatments adds up to $300-$600 annually for many people. A complete 6-8 session underarm laser course at Laser and Me costs a fraction of that over a lifetime horizon, while eliminating the daily ritual entirely.
Beyond cost, there's skin health. Repeated shaving causes microtrauma to the skin, can increase hyperpigmentation in the underarm area over time, and is the primary driver of ingrown hairs. Many clients notice that within a few sessions, the skin texture of their underarm, including any darkening from chronic shaving, begins to improve noticeably as the follicle stimulation decreases.
What Does Underarm Laser Hair Removal Cost in NYC?
In New York City, underarm laser hair removal typically costs $75-$150 per session at established medspas. At Laser and Me, we offer competitive pricing relative to other Manhattan medical spas, with package deals that reduce the per-session cost when you commit to a full treatment course.
Given that 6-8 sessions are typical for full results, the total investment for a complete underarm course at Laser and Me is often less than a single year's worth of waxing appointments at a mid-range NYC salon. Visit our pricing page for current rates and package options.
Frequently Asked Questions
How many laser sessions are needed for permanent underarm hair removal?

Is underarm laser hair removal safe for dark skin?
Yes. Laser and Me uses the Cynosure Elite+ with a 1064nm Nd:YAG wavelength for clients with Fitzpatrick IV-VI skin types. This wavelength bypasses surface melanin and targets the follicle safely, reducing the risk of hyperpigmentation that can occur with the wrong device or settings.
Will laser hair removal reduce underarm darkening?
Many clients notice improvement in underarm skin tone after beginning laser treatment. Chronic shaving causes repeated microtrauma and can contribute to post-inflammatory hyperpigmentation (PIH) in the underarm area. As shaving decreases and eventually stops, the skin often responds by brightening and evening in tone over the course of treatment.
Can I use deodorant before my underarm laser session?
We ask clients to arrive at their session with clean, dry underarms, free of deodorant, antiperspirant, and any lotions. Deodorant residue can interfere with laser treatment and increase the risk of skin irritation. After the session, wait 24 hours before applying aluminum-based antiperspirants.
