Laser Hair Removal is particularly suited to the Underarm / armpit area. That’s because it eliminates three problems commonly associated with temporary hair reduction methods for arms:

• Skin Sensitivity — The skin on the underarms is particularly sensitive. That’s why it’s prone to red rashes, razor bumps and ingrown hair that occur in the aftermath of shaving or creams.

• The Shadow Effect — The proverbial five o’clock shadow isn’t exclusive to the face. That goes for the armpit and underarm area as well. For most people, the hair follicle remains visible on the surface of the skin of the armpits even after shaving.

• The Stubble Effect — And, of course, temporary solutions mean that coarse, dark hair will grow back in. As a result, unsightly stubble appears without regular upkeep.

Laser hair removal for armpits or underarms works the same way it does for the rest of the face and body. Specifically, that laser machine targets the melanin, or pigment, in hair follicles with concentrated light energy.

The laser emits a specific wavelength of light that is selectively absorbed by the melanin within each hair. This absorption converts the light into heat, which damages the hair follicle and inhibits its ability to produce new hair.

Because the laser targets pigment, it is most effective on darker hair and lighter skin. The treatment is designed to damage hair follicles without harming the healthy surrounding skin on the armpits / underarms.

Hair grows in cycles, so multiple sessions are needed to catch hairs during their active growth phase (called the anagen phase). Over a series of treatments, this process results in significant and lasting reduction of hair growth in the treated area.

Laser hair removal is generally quick, with minimal discomfort and downtime, making it a popular choice for long-term hair reduction.

Temorary fixes, like waxing, shaving or depilatories, get rid of unwanted hair only at the surface level of the armpits.

On the other hand, the laser device goes underneath the skin to reach the hair follicle at its source on the underarm area

By destroying the hair follicle, the underarm hair either grows back softer and less coarse, or doesn’t grow back at all.

Bottom line: no razor bumps, no armpit irritation or skin rashes, no shadow, no maintenance on the underarms.

The procedure is actually quite simple on the underarms. Specifically, since the armpits are a small area of the body, they are typically done quickly — typically in around 15 minutes to under an hour.

First, a skincare professional will apply a numbing cream to the armpit.

Then, she will pass a handheld laser device over the treatment area to target thousands of hairs at the follicle. The sensation is usually described as like a light snap of a rubber band. 

Treatment times vary based on size of the area and hair density, with most clients reporting little to no pain.

Normal activities can typically be resumed immediately after treatment.

Lasers for armpits work best in a series, which can be determined by you and your practitioner.

This streamlined approach makes  laser sessions ideal for busy individuals seeking permanent hair reduction with minimal disruption — a key reason it consistently ranks as a top choice for laser hair removal Manhattan and best laser hair removal NYC searches.

Permanent armpit hair removal is possible with a series of sessions.

Hair typically grows in 4-6 weeks cycles, depending on the part of the body. During each session, Laser Hair Removal for arms will get about 80% of this actively growing hair on the underarms.

Therefore, it usually takes 5-8 treatments to effectively treat one area. We recommend that you return every 4-6 weeks to target new active growth.

Additional sessions for armpits may be needed after that. By adhering to scheduled treatments, you can achieve a permanent underarm hair removal solution.

When considering how many sessions are needed for effective laser hair removal on the armpits, several factors come into play:

1. Hair type and color: Darker, coarser hair responds faster and may require fewer sessions.

2. Treatment area: Smaller areas like the armpit or upper lip might need fewer sessions than larger areas like the back or legs.

3. Skin tone: Certain laser technologies are tailored for different skin tones, which can affect treatment duration.

4. Individual hair growth cycles: Since hair grows in phases, multiple sessions spaced 4-6 weeks apart are essential to catch hairs in the active growth phase.

Maintaining scheduled appointments and following post-treatment care guidelines will maximize results and ensure safe, effective, and lasting hair removal.

Armpit laser hair removal is considered one of the more affordable treatment areas due to its relatively small size. Because the underarm area doesn’t require as many laser pulses compared to larger regions like legs or back, sessions tend to be quicker and use less energy overall.

However, achieving optimal and lasting results typically requires multiple sessions spaced over several weeks to target hair during its active growth phases. This is why most medspas recommend purchasing treatment packages rather than single sessions. Packages not only provide the best value but also ensure consistency in your hair reduction journey.

Investing in a package allows you to lock in a better rate and receive a personalized treatment plan that addresses your specific hair removal needs. Whether you’re looking to eliminate razor bumps, reduce irritation, or enjoy smooth, hair-free underarms long-term, a package deal is usually the most effective and economical approach.

It’s best to speak with a Laser Hair Removal Specialist, in order to determine the specific Armpit Laser Cost for you.

At Smooth Synergy® Laser Center, we offer only the Candela GentleMax Pro — a dual-wavelength laser hair removal system, combining two of the most effective technologies in one device — the 755 nm Alexandrite Laser and the 1064 nm Nd:YAG Laser.

This pairing allows safe, effective, and permanent hair reduction on the armpits for all skin tones, from the lightest to the deepest, making it the gold standard in NYC medspas.

To understand why Candela stands out, it helps to compare it with other leading laser technologies on the market:

Candela Gentle Lase — Alexandrite Laser (755 nm)
The Alexandrite laser is well-known for its speed and precision. It targets melanin in the hair follicle, making it ideal for lighter to medium skin tones (Fitzpatrick Skin type I–III).

Treatments are quick, making it perfect for large areas like legs or back. The Candela Laser integrates this technology for clients with lighter skin tones who want maximum efficiency and lasting results.

Candela Gentle Yag — Nd:YAG Laser (1064 nm)
The Nd:YAG laser penetrates deeper into the skin and bypasses most of the pigment in the surface layers. This makes it safe and effective Laser Hair Removal for darker skin tones (Fitzpatrick IV–VI) and for permanently tanned skin.

While it may require slightly more sessions than Alexandrite for full results, its safety profile for pigmented skin is unmatched.

The GentleMax Pro’s Nd:YAG capability is why it’s trusted for laser hair removal Manhattan clients with deeper skin tones.

Diode Laser (~800–810 nm)
The Diode laser is a versatile single-wavelength system used in many clinics. It works well for a range of skin types and hair colors, but typically does not match the speed of Alexandrite or the safety of Nd:YAG for darker skin.

Some medspas choose Diode as a budget-friendly alternative, but it often requires more treatment sessions for the same level of hair reduction.

Ruby Laser (694 nm)
The Ruby laser was one of the first hair removal lasers ever developed. It’s highly effective for very fair skin but poses a high risk of pigmentation issues on medium to dark skin tones.

Because it’s slower and less versatile, it’s rarely used in professional Laser Centers — having been replaced by more advanced systems like the GentleMax Pro.

IPL (Intense Pulsed Light)
While technically not a laser, IPL uses broad-spectrum light to reduce hair growth. It’s common in at-home devices and some spas, but it’s less precise and usually requires more treatments for results.

IPL works best on light skin with dark hair, but it can’t match the customization, safety, and permanence of true laser systems like Candela.

Both Candela Systems, including the Gentle Yag and Alexandrite (Gentle Lase) offer these advantages:

• Top Laser Hair Removal Effectiveness

The Candela Laser operates at a higher wavelength of light than many competitors. As a result, it penetrates more deeply into the skin, targeting the hair follicle for destruction both more quickly and effectively.

• Unparalleled Laser Hair Removal Safety

The higher wavelength also reduces the amount of energy dispersed into healthy surrounding tissue. As a result, it minimizes the risk of laser burns.

Additionally, both the Alexandrite and Nd: YAG Laser device longer pulse duration or pulse width. This works to assure energy is delivered over a longer period of time. It’s simple: fewer pulses coming in contact with the epidermis translates into a safer treatment. 

• Advances in Laser Hair Removal Pain Reduction

Both Alexandrite (Gentle LASE) and Gentle YAG come with a dynamic cooling device (DCD). During treatment, it sprays the epidermis with a cooling burst of cryogen in adjustable durations — milliseconds before the laser pulse. DCD helps ensure more comfortable treatment, while minimizing damage to the skin.

• The Best Laser Hair Removal Results

Shaving, waxing, depilatories and cream are temporary solutions that leave the hair follicle intact. On the other hand, Laser Hair Removal works to destory the hair follicle — stopping hair growth at its source. As a result, it’s the long-lasting solution to get rid of unwanted hair. After a series of session, hair will either be significantly reduced or gone forever.
