Is Laser Hair Removal Safe for Underarms? A Complete Guide by Perizia Aesthetics in Jupiter, FL
For many people, shaving or waxing underarms is a constant hassle that often leaves behind irritation, ingrown hairs, or dark shadows. But when patients consider laser treatments, one question comes up again and again: Is laser hair removal safe for underarms?
At Perizia Aesthetics, we specialize in safe and effective laser hair removal in Jupiter, Florida. Our physician-supervised team is trained to work with all skin types and uses advanced, FDA-cleared technology to deliver smooth, lasting results. If you’ve been debating whether to try underarm hair removal near you, this guide will give you the evidence, clinical data, and professional insight you need to make an informed choice.
What Is Underarm Laser Hair Removal?
Laser hair removal works by delivering non-ionizing light energy directly to the hair follicle. The pigment in the follicle absorbs the laser energy, which damages the follicle’s ability to grow hair without harming surrounding skin.
Because the underarm area has coarse, dark hair and a relatively fast growth cycle, it tends to respond especially well to this treatment. Unlike at-home devices, which are considered cosmetic, medical-grade lasers used in clinics like ours are FDA-cleared and operated by trained professionals under strict safety standards (U.S. FDA).
Is It Safe for Underarms?
Safety is one of the top concerns for anyone considering this procedure. The good news is that underarm laser hair removal is widely considered safe when performed in a licensed medical environment.
Typical, short-lived side effects include:
- Mild redness
- Slight swelling around hair follicles (perifollicular edema)
- Temporary discomfort that usually resolves within 24–48 hours
These are expected and show that the laser has effectively targeted the follicles. According to the American Academy of Dermatology, most patients recover quickly and return to normal activities the same day.
Rare but possible side effects may include: blistering, pigment changes, infection, or scarring. These complications are uncommon and typically linked to inexperienced providers or failure to follow aftercare instructions.
One of the most important safety facts: the lasers used for hair removal emit non-ionizing radiation. That means they do not carry the same risks as ionizing radiation (like X-rays) and have no association with cancer or lymph node damage (FDA on laser safety).
With trained providers, proper settings, and eye protection for everyone in the room, the procedure is not only safe but one of the most effective options available for long-term underarm hair reduction.
Clinical Effectiveness: What the Data Shows
The question patients often ask next is: does it really work? The answer is yes, and the evidence is strong.
In clinical studies, underarm laser hair removal consistently delivers measurable, lasting reductions:
- Split-axilla study comparing diode (810 nm) and Nd:YAG (1064 nm):
- At 1 month: 71% (diode) vs 82% (Nd:YAG) reduction
- At 6 months: 35.7% (diode) vs 54.2% (Nd:YAG)
- Pain was lower on the diode side (Wanitphakdeedecha et al., J Eur Acad Dermatol Venereol, 2012).
- At 1 month: 71% (diode) vs 82% (Nd:YAG) reduction
- Diode laser (805 nm) study on axilla with larger spot size: Showed ~29.5% improvement in effectiveness with no serious adverse events (Ann Dermatol, 2015).
- Cochrane evidence review: Found that alexandrite and diode lasers delivered up to 50% hair reduction for at least six months, with moderate-quality evidence.
At Perizia Aesthetics, most patients see 10–25% reduction after their first treatment and require 2–6 sessions spaced about 4–6 weeks apart for optimal, long-lasting results. Maintenance varies, but many remain smooth for months to years before touch-ups.
Tailoring Treatments for All Skin Types
A common myth is that laser hair removal only works on lighter skin. That may have been true when the technology was first developed, but today’s devices allow us to safely and effectively treat all Fitzpatrick skin types (I–VI).
- Light to medium tones (I–III): Alexandrite (755 nm) and diode (800–810 nm) lasers are highly effective.
- Medium to darker tones (IV–VI): Nd:YAG (1064 nm) is preferred because it penetrates deeper and is less absorbed by surface melanin, reducing risks of burns or pigment changes.
The AAD confirms that with the right laser and trained provider, people with every skin tone can benefit safely. At Perizia Aesthetics, we carefully select laser settings based on your skin and hair type, ensuring maximum safety and results.
What to Expect Before, During & After Treatment
Before Treatment
- Shave the underarm area the day before.
- Avoid plucking, waxing, or electrolysis for at least four weeks beforehand.
- Stay out of the sun and tanning beds, as tanned skin increases risks.
- Tell your provider if you are taking any photosensitizing medications, such as certain antibiotics or acne treatments (ASDS medication guidance).
During Treatment
- Protective eyewear will be provided.
- You may feel a snapping sensation, often compared to a rubber band.
- Cooling methods or numbing gels may be used to reduce discomfort.
After Treatment
- Expect temporary redness and swelling.
- Apply cool compresses if needed.
- Avoid direct sun exposure, and use broad-spectrum sunscreen.
- Follow the aftercare instructions given by your provider for best results.
This patient journey ensures that laser hair removal is safe, comfortable, and produces smooth, lasting results.
Benefits Beyond Hair Removal
While the main goal of underarm laser hair removal is smooth, hair-free skin, many patients discover added benefits that improve their daily comfort and confidence.
- Keratosis Pilaris Relief: For patients prone to “chicken skin” or keratosis pilaris, avoiding constant shaving and irritation can reduce flare-ups.
- Fewer Ingrown Hairs: Because the follicle is disabled, the risk of painful ingrowns is dramatically reduced compared to shaving or waxing.
- Hidradenitis Suppurativa Improvement: In some cases, patients with hidradenitis suppurativa (a condition that causes painful underarm flare-ups) experience fewer symptoms when hair follicles are minimized.
These added benefits make laser treatments a healthier choice for long-term skin wellness, not just cosmetic improvement.
Florida-Specific Safety & Licensing Standards
If you live in Florida, it’s natural to wonder about the standards and regulations that govern this type of treatment. Florida law requires that laser and light-based hair removal be performed only by licensed electrologists under the direct supervision of a Florida-licensed physician. This supervision can include oversight through telehealth.
Additionally, the Florida Department of Health requires:
- Active electrology facility license
- Board-approved curriculum and exams for electrologists (such as the IBEC Electrology, Laser & IPL Exam-FL)
- Continuing education requirements, including laser/light-specific training
At Perizia Aesthetics, we take these requirements seriously. Our facility, team, and physician supervision meet or exceed all Florida safety regulations, giving our Jupiter patients confidence that treatments are both compliant and secure.

FAQs About Underarm Laser Hair Removal
Does it hurt?
Most patients describe the feeling as a quick snap, similar to a rubber band. Cooling systems or numbing gels make the process more comfortable. In clinical studies, diode lasers were rated as less painful than Nd:YAG lasers, while both were effective.
How many sessions will I need?
Most patients see results after the very first session, with 10–25% hair reduction. On average, 2–6 sessions spaced 4–6 weeks apart are recommended for long-lasting results. Maintenance may be needed depending on hair type and growth cycles.
Is it permanent?
The FDA defines the results as “permanent hair reduction,” meaning that treated follicles don’t grow hair again. Many patients enjoy months to years of smooth underarms, with touch-ups required for best long-term results.
How safe is it for darker skin?
Today’s Nd:YAG lasers are highly effective and safe for darker skin tones. With the right device and experienced providers, people with all skin types (I–VI) can achieve safe, reliable results.
