Beginner’s Guide to Underarm Laser Hair Removal
Underarm laser hair removal is a method that eliminates hair from the root by delivering laser energy into the skin under the arms. The procedure is quick, and with consistent sessions, it helps achieve hair-free, smooth underarms. It also prevents issues like ingrown hairs and chicken skin bumps often caused by plucking, shaving, or waxing — giving you more confidence to raise your arms and reveal flawless skin.
For those who are new to laser hair removal, this article covers all the essentials — including preparation, pros and cons, cost, types of laser machines, expected results, aftercare, and real reviews — so you can make an informed choice and finally stop wasting time on repeated shaving or plucking.

How Does Underarm Laser Hair Removal Compare to Other Hair Removal Methods?
Laser hair removal is one of the most popular choices today for underarm care. Many people prefer laser treatment for several reasons:
- Longer-lasting results compared to shaving, plucking, or waxing, where hair regrows in just a few days or weeks
- Minimal discomfort, with no burning, stinging, or need for numbing cream
- Reduced skin irritation, lowering the risk of ingrown hairs (Keratosis Pilaris)
- Decreased risk of chicken skin bumps caused by frequent plucking, shaving, or waxing
- Reduced body odor from minimized moisture and bacterial buildup under the arms
- Safety and convenience, as each session typically takes only 10–15 minutes depending on hair density
- Time-saving benefits, eliminating the need for frequent shaving or plucking and reducing concern about regrowth
- Improved confidence, allowing you to dress freely with smoother, cleaner-looking underarms
Common Underarm Hair Removal Methods
Before deciding on laser hair removal, most people have already tried other options:
- Plucking : Slower regrowth but very painful; risks ingrown hairs and uneven skin texture
- Shaving : Quick and convenient but causes irritation; hair regrows within 1–3 days, often thicker and darker
- Waxing : Removes large amounts of hair quickly but is painful; frequent waxing may cause chicken skin or ingrown hairs
- Depilatory creams : Easy to use and fast results, but hair regrows quickly and may cause irritation or ingrown hairs
- IPL devices : Work similarly to lasers but are less effective; poor-quality devices may cause burns or leave dark marks
Each method has different steps, benefits, and limitations. The right choice depends on personal preference.
However, for those seeking convenience and long-lasting results, professional underarm laser hair removal at a certified clinic is the best option. With FDA-approved laser machines and treatments performed by trained practitioners, you can be confident in both safety and long-term effectiveness.

Feeling Shy About Your First Underarm Laser Hair Removal? How to Prepare
For many people who have never tried underarm laser hair removal, it’s completely normal to feel shy or a little anxious. However, there’s no need to worry — everyone experiences a first time.
The procedure is neither scary nor embarrassing, regardless of how much hair you have. The key is to stay relaxed, gather essential information, and prepare yourself properly. With the right mindset, you can confidently undergo your first laser session.
What to Know Before Getting Underarm Laser Hair Removal
When the laser targets the follicular stem cells in the dermis, the melanin pigment in the hair absorbs the laser energy and converts it into heat. This heat damages the follicle and prevents further growth, causing hair to gradually fall out. The results depend on the type and efficiency of the laser machine used.
Preparing for Your First Underarm Laser Hair Removal
When it comes to your first underarm laser treatment, preparation can be divided into two parts: gathering information and preparing yourself physically.
Gathering information before your first treatment
- Learn about the procedure, including methods, pros and cons, and expected results.
- Choose a clinic that is certified, trustworthy, and legally licensed
- Check which type of laser machine will be used to ensure effective and safe results
- Ensure that the procedure is performed by a qualified doctor or trained practitioner
- Compare promotions and prices across multiple clinics for the best value
Preparing yourself before the session
- Avoid plucking or waxing underarm hair for 1–2 weeks before treatment
- Stop using skincare products with alcohol, AHA, BHA, or retinoids at least 3 days before treatment
- Inform your doctor of any medical conditions or regular medications before treatment
Do Different Underarm Laser Machines Produce Different Results?
Different types of laser technologies are used for underarm hair removal, and each has unique characteristics that affect treatment effectiveness and overall results.
Types of Underarm Laser Machines
The most common technologies for underarm hair removal include IPL, Diode Laser, and YAG Laser. Before deciding which laser is best, let’s look at the key features of each:
- IPL (Intense Pulsed Light) → A high-intensity light source, not a true laser, but works similarly (sometimes referred to as “IPL Laser”). With wavelengths between 515–1,200 nm, IPL is less effective compared to true lasers. Results are slower, requiring multiple sessions before hair becomes finer and lighter. The advantage is its lower cost.
- Diode Laser → Offers a range of wavelengths from 800–1,350 nm, adjustable based on hair thickness and color. It gradually reduces and sheds underarm hair, though insufficient energy settings can sometimes cause hair to regrow thicker. Pricing is typically higher than IPL but lower than YAG.
- YAG Laser → Uses a 1,064 nm wavelength, penetrating deep into the follicle to destroy hair at the root. It provides smooth, clear underarms with high efficiency, though at a higher cost compared to other methods.
At V Square Clinic, we use the Cool Yag 1064 program, featuring the Long Pulse Nd: YAG laser (Light B Evo) imported from Italy and Germany. Certified under European standards and FDA-approved in the US, Europe, and Thailand, this laser is suitable for all skin types and hair colors. To maximize comfort, it is paired with the Cryo 7 cooling system, which delivers chilled air during treatment — ensuring the process is pain-free and gentle on the skin.
Which Underarm Laser Do Doctors Recommend as the Best Choice?
Many patients visit clinics after researching different laser options and comparing prices. However, it’s important not to base your decision solely on cost. While all laser devices are designed to remove underarm hair, their effectiveness can vary depending on the technology used.
Another key factor is the color and density of the hair. Darker hair tends to absorb laser energy more effectively than lighter hair. Therefore, selecting the most suitable laser depends on both skin tone and hair color.
At V Square Clinic, our doctors and practitioners carefully assess each patient’s skin tone and hair characteristics to recommend the most suitable laser for safe, effective, and lasting results.
Do Different Prices for Underarm Laser Hair Removal Affect the Results?
Pricing for underarm laser hair removal can vary across clinics, depending on factors such as the type of machine used, the provider’s experience and reputation, and available promotions. It’s important to note that higher prices do not always guarantee better results, and lower prices do not necessarily mean poor quality.
The most important considerations are that the clinic uses standard-certified laser devices and that the procedure is performed by experienced doctors or trained practitioners. This ensures effective results while minimizing potential side effects.

What to Know After Underarm Laser Hair Removal?
After underarm laser hair removal, the treated hair does not fall out immediately. Instead, it continues to grow for a short period before gradually shedding over the next 2–3 weeks. In some cases, temporary side effects such as redness, mild burning, or irritation may occur, which usually resolve within 1–2 days.
If you experience unusual symptoms such as swelling, pain, or rashes, consult your doctor promptly.
How Many Sessions of Underarm Laser Hair Removal Are Needed? How Long Do Results Last?
Visible results often appear after the first session, depending on hair thickness and growth. Most patients undergo a full course of 5–8 sessions to achieve optimal results. Hair regrowth becomes finer and less noticeable, though some strands may still appear. Repeated sessions are required for complete removal. Results generally last 1–2 years or longer.
How Long Should You Wait Between Underarm Laser Sessions?
It is recommended to wait about 4 weeks between treatments. This allows hair in different growth phases to reach the active stage, during which the laser can effectively target and destroy the follicle.
Are There Risks From Repeated Underarm Laser Hair Removal Sessions?
Repeated underarm laser sessions are safe and do not cause long-term damage. However, treatments should be spaced appropriately — usually about once a month — to align with the natural hair cycle.
Aftercare Instructions Following Underarm Laser Hair Removal
- Avoid deodorants or underarm skincare products for 3 days
- Refrain from hot showers or soaking in hot baths for 24 hours
- Avoid exfoliating products such as AHA, BHA, retinol, or vitamin C for 1 week
- Wear loose clothing to reduce friction and irritation
- Apply gentle creams or aloe vera gel to soothe redness and maintain hydration
- Avoid sun exposure or tanning of the underarms for at least 2 weeks
- Do not scrub, rub, or exfoliate the area for 1 week
- Avoid shaving, plucking, or waxing underarm hair for at least 2 weeks

What Else Can Underarm Laser Treatments Improve Besides Hair Removal?
In addition to effectively removing underarm hair, laser treatments can also address other common underarm concerns such as darkness, chicken skin texture, and underarm folds.
Types of Underarm Laser Treatments
- Laser for dark underarms → Targets melanin to gradually lighten pigmentation and reduce darkness caused by hair and friction
- Laser whitening → Brightens the skin tone, improves darkness caused by ingrown hairs or improper hair removal, enhancing confidence when raising your arms
- Laser for chicken skin texture → Also known as Yag Reju or skin rejuvenation laser, it stimulates collagen to smooth uneven skin and bumps from plucking, shaving, or waxing
- Laser for underarm folds → Rejuvenates skin creases and folds caused by friction or shaving by stimulating collagen and elastin, restoring smoothness
VSQ Tips! What Should You Consider When Seeing Underarm Laser Promotions?
If you come across attractive underarm laser promotions — such as new customer discounts, free first trials, loyalty packages, or 10–12 session bundle deals — don’t rush to sign up immediately.

How long is the waiting time for an appointment?
Checking these details beforehand ensures you make a safe, effective, and worthwhile choice.
How to Choose the Best Clinic for Underarm Laser Hair Removal?

Q&A – Underarm Laser Hair Removal
Does Laser Hair Removal Cause Excessive Underarm Sweating?
Excessive sweating after laser hair removal may occur temporarily as the body adjusts. This happens because some sweat glands are affected, prompting the remaining ones to work slightly harder. The condition is temporary and gradually improves on its own without long-term effects.
Can Underarm Laser Hair Removal Permanently Remove Hair?
Yes, underarm laser hair removal can lead to permanent reduction when done consistently. In most cases, hair regrowth decreases by 80–90%. Any regrown hair tends to be much finer, shorter, and significantly less noticeable.
Is It Safe to Use Different Types of Lasers in Each Session?
Yes, switching between laser machines is safe and has no harmful effects. For example, if one device provides limited results, a more advanced or suitable laser can be used in following sessions. At V Square Clinic, our doctors can recommend the most suitable laser based on your skin and hair type for the best outcome.
Is It Harmful to Shave or Wax After Laser Hair Removal?
After laser hair removal, you should avoid shaving, plucking, or waxing. These methods can interfere with the hair follicles that have already been weakened or destroyed by the laser, increasing the chance of regrowth. Instead, it is best to wait for your next scheduled session — our team will assess the remaining hair and adjust the energy level accordingly.
Conclusion – Underarm Laser Hair Removal for Smooth, Confident Skin
Compared with traditional methods such as shaving, plucking, or waxing, underarm laser hair removal delivers superior, longer-lasting results. It also helps reduce problems like ingrown hairs, chicken skin, and uneven texture, since the laser targets hair follicles directly and permanently weakens them.
For the best results, treatment should be performed at a certified clinic, under the supervision of experienced doctors or trained practitioners. Instead of focusing only on promotional prices, prioritize safety, effectiveness, and long-term outcomes. This ensures that your underarms remain smooth, hair-free, and confidently ready to reveal.
