Most people put off booking laser hair removal for one reason: they are convinced it is going to hurt. The word “laser” alone sounds intense. Add in stories from friends who had it done ten years ago on older machines, and it is easy to talk yourself out of it.
Does laser hair removal hurt? Most patients rate it 2 to 5 out of 10 on a pain scale. The sensation is commonly described as a rubber band snapping against the skin. It is brief, manageable, and significantly less painful than waxing. Modern laser technology with built-in cooling systems has made the experience far more comfortable than it was even five years ago.
And here is the part most people do not expect: it gets easier every single session. As the hair thins, the discomfort drops. By session 4 or 5, most patients barely notice it.
At Deep Aesthetics, we offer laser hair removal with modern cooling technology and trained specialists at our London Canary Wharf and Birmingham clinics. Underarms start from just £7, bikinis from £18.50, and full body and face at £89.
In this blog, we give you an honest breakdown of what laser hair removal actually feels like, which body areas hurt most, how it compares to waxing, and exactly how to make your sessions as comfortable as possible.
What Does Laser Hair Removal Actually Feel Like?
Forget what you have heard from someone who had treatment a decade ago on an old machine. Modern laser hair removal feels nothing like the horror stories suggest.
The most common description is a quick snap of warmth against the skin. Each laser pulse lasts a fraction of a second. It is not a constant burning sensation. It is a series of brief, sharp prickles with gaps between each one.
Think of it like this. Imagine someone lightly flicking a warm rubber band against your skin, once every second or so. That is roughly what it feels like on most body areas. Some areas feel like a mild warm tingle. Others feel like a sharper pinch. But each individual pulse is over almost instantly.
The first session is always the most uncomfortable. Your hair is at its thickest and densest, which means each follicle absorbs maximum laser energy. More energy absorbed equals more heat generated, which means more sensation.
But something interesting happens from session 2 onwards. The treated hair grows back finer and thinner. Finer hair absorbs less energy. Less energy means less heat. Less heat means less sensation. By the time you reach session 4 or 5, many patients say they can barely feel anything at all.
A typical underarm session takes about 10 minutes. A bikini session takes 15 to 20 minutes. During that time, you feel perhaps 50 to 100 individual pulses, each lasting less than a second. The total “uncomfortable” time is measured in seconds, not minutes.
Pain Levels by Body Area: What to Expect
Not every body area feels the same during laser treatment. The difference comes down to three things: how thin the skin is, how many nerve endings are concentrated in that area, and how coarse the hair is.
Face (Upper Lip, Chin, Jawline)
Pain level: 4 to 6 out of 10
The upper lip is the area most patients flag as uncomfortable. The skin is thin, the nerve endings are dense, and it sits close to the nose and teeth, which amplifies the sensation.
The good news? The treatment area is tiny. An upper lip session takes 5 to 10 minutes. The discomfort is real but extremely brief. Most patients describe it as a series of quick, sharp stings that are over before they have time to worry about it.
Chin and jawline are slightly less sensitive, typically sitting around 3 to 5 out of 10.
Underarms
Pain level: 3 to 5 out of 10
The skin under the arms is thin, which makes it a bit more sensitive than the legs or arms. But the treatment area is so small that each session takes about 10 minutes. Most patients tolerate it comfortably, especially from the second session onwards.
The first session can catch people off guard because underarm hair tends to be coarse and dark, which absorbs a lot of laser energy. Once that thick hair has been treated, subsequent sessions feel noticeably milder.
Bikini Line and Brazilian
Pain level: 5 to 7 out of 10
This is the area most patients worry about, and it is the most sensitive for most people. The skin is thin, the nerve endings are concentrated, and the hair is typically coarse and dark.
A standard bikini line treatment is less uncomfortable than a full Brazilian because the coverage area is smaller and stays at the edges. A Brazilian covers the entire area, including more sensitive inner zones.
Numbing cream is strongly recommended for this area. Applied 30 to 45 minutes before treatment, it can bring the pain level down to 2 to 3 out of 10 even in the most sensitive spots.
Legs
Pain level: 2 to 4 out of 10
Legs are one of the most comfortable areas for laser treatment. The skin is thicker, the nerve endings are more spread out, and most patients describe the sensation as a mild warmth or light prickling.
The lower legs can feel slightly sharper than the upper thighs, particularly around the ankles and knees where the skin sits closer to the bone. But even in those spots, the sensation is brief and very tolerable.
Arms, Back, Chest, Stomach
Pain level: 2 to 4 out of 10
These areas are generally very comfortable. The skin is thick enough to buffer the laser energy, and nerve density is lower than in the face or bikini area.
Male chest and back treatments may feel slightly more intense due to coarser, denser hair. But the sensation remains in the mild to moderate range for the vast majority of patients.
Here is a quick reference:
| Body Area | Pain Level (1-10) | What It Feels Like |
| Upper Lip | 4-6 | Sharp, quick stinging |
| Chin / Jawline | 3-5 | Mild snapping |
| Underarms | 3-5 | Warm prickling |
| Bikini Line | 4-6 | Moderate stinging |
| Brazilian | 5-7 | Sharp heat, most sensitive |
| Legs | 2-4 | Mild warmth |
| Arms | 2-3 | Very mild |
| Back / Chest | 2-4 | Mild warmth |
| Stomach | 3-4 | Moderate prickling |
Does Laser Hair Removal Hurt More Than Waxing?
This is the comparison most people want to know. And the answer is clear: laser is significantly less painful than waxing for the vast majority of patients.
Waxing works by ripping hair out from the root in one sharp pull. The pain is immediate, intense, and sustained for several seconds. Anyone who has had a bikini wax knows exactly what that feels like.
Laser works differently. Each pulse of light lasts a fraction of a second. There is no pulling, no tearing, no sustained pain. Just a brief snap of heat, then nothing until the next pulse.
But here is the difference that matters most. Waxing pain stays the same every single session. The hair grows back at full thickness every time, so the pain never decreases. Your 50th bikini wax hurts just as much as your first.
Laser pain decreases with every session. As the hair thins, each session becomes more comfortable. By the midpoint of your course, the sensation is noticeably milder. By the end, most patients barely register it.
| Method | Pain Level (1-10) | Pain Duration | Gets Less Painful? |
| Shaving | 1 (razor burn risk) | Seconds | No |
| Laser | 2-5 | Fraction of a second per pulse | Yes, each session easier |
| Waxing | 5-8 | Several seconds per strip | No, same every time |
| Electrolysis | 4-7 | Constant during treatment | Slightly |
Laser offers the best balance of effectiveness and comfort. It hurts less than waxing, delivers longer-lasting results, and gets easier over time.
Why Does Pain Decrease After Each Session?
This is the part that surprises most first-time patients.
After each laser session, the treated hair follicles are damaged. The hair that grows back is finer, thinner, and lighter than the original. This is a sign the treatment is working.
Finer hair contains less melanin. Less melanin means the follicle absorbs less laser energy. Less energy absorbed means less heat generated. And less heat means less sensation on your skin.
At the same time, the total number of active follicles decreases with each session. Fewer follicles being targeted per session means fewer pulses, less overall treatment time, and less cumulative discomfort.
By session 4 or 5, the difference is dramatic. Patients who rated their first session a 5 out of 10 often rate session 5 a 1 or 2. Some say they cannot feel it at all.
This is something unique to laser. Waxing pain never decreases because the hair grows back at full thickness every time. Shaving irritation does not improve with repetition. Only laser gets progressively more comfortable the more you do it.
What Affects How Much Laser Hair Removal Hurts?
Same treatment, same clinic, two different patients, two different experiences. Several factors explain why.
Skin Sensitivity and Pain Tolerance
Pain is subjective. One person’s 3 out of 10 is another person’s 5. Your natural pain threshold plays a significant role in how you experience laser treatment.
Skin sensitivity also varies. Some people have naturally more reactive skin that responds more intensely to heat and light. If you know your skin is sensitive to waxing, threading, or even hot water, you may feel laser slightly more than average.
One factor many people do not consider: the menstrual cycle. Skin sensitivity increases in the days leading up to and during your period. Some patients prefer to schedule sessions for the week after their period when sensitivity is lowest.
Hair Thickness and Colour
Coarser, darker hair absorbs more laser energy than fine, light hair. More energy absorbed means more heat in the follicle, which means more sensation on the surface.
This is why the first session, when hair is at its thickest and darkest, is always the most uncomfortable. As treatment progresses and hair thins, the sensation drops significantly.
Laser Technology
The machine your clinic uses has a direct impact on comfort.
Older laser systems deliver energy in single, powerful shots. Each pulse hits hard, which is why people who had treatment years ago often describe it as painful.
Modern diode and Nd:YAG lasers use advanced cooling systems including cold air, contact cooling tips, and cryogen sprays. These cool the skin surface before, during, and after each pulse, dramatically reducing the heat sensation.
IPL devices are not true lasers. They use broad-spectrum light that tends to spread more heat across the skin surface, which can feel hotter and less precise than a focused laser beam.
The technology matters. Always ask which laser your clinic uses. If they have modern cooling-integrated equipment, the experience will be significantly more comfortable.
Practitioner Skill
An experienced practitioner calibrates the laser settings specifically for your skin tone, hair type, and the body area being treated. Proper calibration means the laser is powerful enough to destroy the follicle but not so intense that it causes unnecessary discomfort.
An inexperienced operator may set the power too high, causing unnecessary pain. Or too low, which means less discomfort but also less effective treatment, requiring more sessions and ultimately more total discomfort overall.
Skill matters as much as the machine.
How to Make Laser Hair Removal Less Painful
You cannot eliminate sensation entirely, but you can reduce it significantly. These practical steps make a real difference.
Use Numbing Cream
Topical anaesthetic cream applied 30 to 45 minutes before treatment numbs the skin surface and can reduce pain to 1 to 3 out of 10 even on sensitive areas like the bikini line. Most clinics either provide numbing cream or recommend you apply your own before arriving.
This is the single most effective thing you can do to reduce discomfort, especially for your first session.
Avoid Caffeine Before Your Session
Caffeine heightens skin sensitivity and lowers your pain threshold. Skip coffee, tea, and energy drinks for 2 to 3 hours before your appointment. The difference is noticeable.
Stay Hydrated
Well-hydrated skin is less reactive to laser energy. Drink plenty of water in the 24 hours before your session. Dehydrated skin tends to feel more sensitive and can react more strongly to heat.
Avoid Tanning and Sun Exposure
Tanned or sunburned skin is significantly more sensitive to laser. The melanin in tanned skin absorbs more laser energy, increasing both discomfort and the risk of side effects. Stay out of direct sun for at least 2 weeks before your session.
Shave the Area Before Your Appointment
Most clinics ask you to shave the treatment area 24 hours before your session. Shaving removes the surface hair so the laser energy goes directly to the follicle rather than heating the hair shaft above the skin. Less surface hair means less heat, which means less discomfort.
Do not wax or pluck before treatment. The follicle root needs to be present for the laser to target it.
Choose a Clinic with Modern Cooling Technology
Built-in cooling systems, whether cold air, contact cooling, or cryogen spray, make a massive difference in comfort. If you are comparing clinics, ask whether their laser has integrated cooling. If it does not, seriously consider finding one that does.

Frequently Asked Questions
Question: Does laser hair removal hurt?
Answer: Most patients rate the pain 2 to 5 out of 10 depending on the body area. The sensation is commonly described as a rubber band snapping against the skin. Each pulse lasts a fraction of a second. Modern lasers with cooling technology have made treatment significantly more comfortable than older devices. Pain also decreases with each session as hair becomes finer.
Question: What does laser hair removal feel like?
Answer: Quick pulses of warm, prickling heat. Each pulse lasts a fraction of a second, followed by a brief pause before the next one. It is not a constant pain but a series of brief sensations. Most patients describe it as a mild snap or warm pinch. The experience varies by body area, with legs and arms feeling very mild and bikini area feeling more intense.
Question: Which body area hurts most during laser hair removal?
Answer: The bikini and Brazilian area is the most sensitive for most patients, rated 5 to 7 out of 10. The upper lip is also sensitive at 4 to 6 out of 10. Legs and arms are the least painful, typically 2 to 4 out of 10. Numbing cream applied 30 to 45 minutes before treatment can reduce discomfort significantly on all sensitive areas.
Question: Is laser hair removal more painful than waxing?
Answer: No. Most patients find laser significantly less painful than waxing. Waxing rips hair from the root causing sharp, intense, sustained pain that lasts several seconds per strip. Laser delivers brief pulses of heat lasting a fraction of a second each with no pulling or tearing sensation. Waxing pain stays the same every session, while laser pain decreases as hair thins over time.
Question: Does laser hair removal get less painful over time?
Answer: Yes. Pain decreases with each session because the treated hair grows back finer and thinner. Finer hair absorbs less laser energy, producing less heat and less sensation. The total number of active follicles also decreases, meaning fewer pulses per session. By session 4 or 5, most patients report feeling very little discomfort compared to their first session.
