What Is Underarm Laser Hair Removal?
Underarm laser hair removal is a non-invasive treatment that uses concentrated beams of light to target and destroy hair follicles in the underarm area.
The pigment (melanin) in the hair absorbs the light, which then damages the follicle to slow or stop future hair growth.
Because hair grows in cycles, several sessions are needed to treat all hair effectively – but once you complete the recommended sessions, you’ll enjoy significantly reduced hair growth or even permanent hair removal.
Why People Love Laser Hair Removal for Underarms
Long-Lasting Results
Say goodbye to daily shaving or bi-weekly waxing. With laser treatments, you’ll notice a gradual thinning of the hair until many follicles stop producing hair altogether.
Fast and Convenient
Underarms are one of the smallest areas to treat, which makes this one of the quickest laser procedures available – typically around 5 to 10 minutes per session.
Less Irritation
No more razor burn, red bumps, or itchy regrowth. Laser hair removal leaves your skin smoother, cleaner, and less irritated than shaving or waxing.
Boosted Confidence
Whether you’re wearing a sleeveless top or hitting the beach, you’ll feel more confident without worrying about visible underarm hair or shadowing.
How Many Sessions Will You Need?
Hair grows in three phases: anagen (active), catagen (transition), and telogen (resting). Laser hair removal is only effective on hair in the active phase, which is why multiple sessions are necessary.
Most people need:
- 6 to 8 sessions, spaced 4 to 6 weeks apart, for optimal results
- Occasional maintenance sessions (1–2 times a year) to stay hair-free
Results can vary based on your hair color, skin tone, and hair thickness.
Is It Painful?
While not completely painless, many people describe the sensation as similar to a rubber band snapping against the skin.
Some modern devices come with cooling technology to make the experience more comfortable.
If you have sensitive skin, a topical numbing cream can be applied before treatment.
Good news: It’s still far less painful than waxing – and much quicker, too!
What to Expect Before, During, and After Treatment
Before Your Appointment:
- Shave the area 24 hours before treatment
- Avoid waxing, plucking, or bleaching for 4 weeks prior
- Stay out of the sun (no tanning) for at least 2 weeks
- Skip deodorant and skincare products on treatment day
During Your Session:
- The technician will clean the area and give you protective eyewear
- A cooling gel may be applied
- The laser will deliver pulses of light to your underarms – typically under 10 minutes
Aftercare:
- Avoid hot showers, saunas, and exercise for 24–48 hours
- Skip deodorant for 24 hours or until any redness subsides
- Apply aloe vera gel or a soothing lotion to reduce redness or swelling
- Use sunscreen if underarms will be exposed to sunlight
Is It Safe for All Skin Types?
Laser hair removal is generally safe for most skin types. However, newer laser technologies like Nd:YAG lasers are especially good for darker skin tones, reducing the risk of burns or discoloration.
Always choose a licensed professional or certified laser technician who understands how to match the right laser to your skin tone and hair type.
How Much Does It Cost?
Pricing can vary depending on your location and the clinic, but here’s a general idea:
- Per session: $50–$150
- Full package (6–8 sessions): $300–$800
Some clinics offer bundled deals or seasonal promotions, so be sure to ask!
Who Should Avoid It?
Laser hair removal may not be suitable for:
- Pregnant or breastfeeding individuals
- People with active skin infections or open wounds in the treatment area
- Those with very light, gray, or red hair, as the laser may not effectively target hair with little melanin
Always consult a professional before starting treatment to ensure it’s right for you.
Absolutely – if you’re ready to ditch the razor and embrace smooth, low-maintenance underarms, laser hair removal is a game-changer.
It’s quick, safe, and effective for most people, offering long-term results that leave you feeling fresh, clean, and more confident every day.
