Laser hair removal has become one of the most sought-after cosmetic procedures for individuals looking to remove unwanted hair effectively and with long-term results. But is laser hair removal a good idea for everyone?
This comprehensive guide explores the benefits, drawbacks, and considerations of laser hair removal treatment, helping you determine if it’s the right choice for you.
What Is Laser Hair Removal?
Laser hair removal is a treatment that uses a high intensity beam of light to target and destroy hair follicles. It stops new hair growth and can result in long term hair reduction or in some cases permanent hair removal. This treatment is most effective on people with dark hair and light skin, but advancements in cosmetic dermatology have made it suitable for all skin tones and hair colours.
How Does Laser Hair Removal Work?
During the treatment the laser targets the melanin in the hair follicle, heating it up to a point where the follicle is damaged and can no longer support hair growth. The laser is very specific so the surrounding skin is left untouched. Modern devices including intense pulsed light (IPL) systems can do customised treatments for different skin types and areas of the body.
Benefits of Laser Hair Removal
- Long Term Hair Reduction
- Laser hair removal can result in significant and often permanent hair loss after a series of treatments. It’s most effective on areas like the bikini line, upper lip and legs.
- Reduces Ingrown Hairs
- Unlike other hair removal methods like waxing or shaving, laser hair removal targets the hair root so it can’t curl back into the skin.
- Precision
- The treatment targets specific hair follicles so it’s perfect for small or sensitive areas like the upper lip or underarms.
- Time Saving
- Sessions are only a few minutes for small areas, larger areas like the legs may take longer. Once the initial course is complete you only need top up treatments every now and then.
- Cost Effective in the Long Run
- Although the cost of laser hair removal is higher upfront than shaving cream or waxing kits, it’s a worthwhile investment.
Disadvantages of Laser Hair Removal
Initial Cost
- Cost varies depending on the area of the body and clinic but is more than temporary methods like waxing or shaving.
Temporary Discomfort
- The laser pulses feel like a rubber band snapping against the skin. For sensitive people this can be uncomfortable, but most clinics have cooling devices or cold gel to help with the sensation.
Skin Irritation
- Common side effects are redness, swelling or mild irritation in the treated areas. These usually subside within 24-48 hours and can be managed with anti-inflammatory creams.
Multiple Treatments Required
- To get optimal results you need to have several sessions 4-6 weeks apart. This allows the laser to target the hair when it’s in its growth phase.
Not Suitable for All Skin and Hair Types
- Although advancements in cosmetic dermatology have made it more inclusive, people with light hair colours or certain skin tones may not get results.
Treatment Areas
Laser hair removal is versatile and can be done on almost any area of the body:
- Face: Upper lip, chin, sideburns.
- Underarms: One of the most popular areas.
- Bikini Line: For smooth hair free skin in sensitive areas.
- Legs: For those tired of shaving.
- Back and Chest: Common areas for men to remove hair.
Before Laser Hair Removal
To get the most out of your laser treatments and minimize risks follow these steps before your session:
- Avoid Sun Exposure: Sunburnt or tanned skin increases the risk of skin irritation and pigmentation changes. Use sunscreen or don’t use tanning beds.
- Cleanly Shave the Area: The laser is most effective when the hair is short but the follicle is intact.
- Avoid Other Hair Removal Methods: Don’t wax or pluck as it removes the follicle the laser targets.
- Don’t Use: Skin bleaching cream or harsh exfoliants in the days leading up to your treatment.
The Treatment: What to Expect
During the treatment the technician will apply a cooling device or cold gel to the skin. You’ll wear protective goggles and the laser will emit a concentrated beam of light to the hair follicles. The sensation varies but is often described as a mild snapping feeling. Smaller areas like the upper lip take a few minutes, larger areas like the legs may take up to an hour.
Aftercare for Treated Skin
Proper aftercare is key to get optimal results and avoid complications:
- Avoid Sun Exposure: Keep the treated areas covered and use sunscreen.
- Use Anti-Inflammatory Creams: Soothe irritation with dermatologist recommended products.
- Avoid Hot Showers: Use lukewarm water to not irritate the treated skin.
- Don’t Use Harsh Products: Avoid exfoliants, retinoids and products with alcohol for a few days post treatment.
Other Options to Laser Hair Removal
While laser hair removal is effective, it’s not the only way to remove unwanted hair:
- Electrolysis: A medical procedure that uses electric currents to destroy individual follicles. Suitable for all hair colours but time consuming.
- Waxing and Sugaring: Removes body hair at the root but can cause ingrown hairs.
- Depilatory Creams: Temporarily dissolves surface hair but can irritate sensitive skin.
- Shaving: Quick and easy but requires frequent maintenance and can lead to more hair growth over time.
Is It Worth It?
Whether laser hair removal is for you depends on your goals, budget and skin type. Here are some to consider:
- Long Term Benefits: If you want permanent hair removal, laser treatments are one of the best options.
- Convenience: Fewer maintenance sessions means less time compared to other hair removal methods.
- Cost Effective: Although the initial cost is higher, it will save you money in the long run by not having to buy razors, waxes or shaving creams.
Choose the Right Clinic
To have a safe and effective experience choose a clinic that values quality and professionalism:
- Experienced Technicians: Choose certified practitioners like ClinicTwenty2, with experience in dermatologic surgery or cosmetic dermatology.
- Latest Technology: Modern lasers can treat a wider range of skin tones and hair colours.
How Laser Hair Removal Works
Laser hair removal is based on the principle of selective photo thermolysis which means the laser targets the pigment in the hair without damaging the surrounding skin. The laser’s energy is absorbed by the melanin in the hair shaft and follicle, generating heat that disables the follicle’s ability to produce hair. Since hair grows in cycles, the laser is most effective during the active growth phase (anagen phase) which is why multiple sessions are required to catch all hairs at the right stage.
Laser Types
Not all lasers are created equal and the type of laser used can affect the results. Here are the common lasers used in hair removal treatments:
- Alexandrite Laser: For lighter skin tones; fast and effective for large areas.
- Diode Laser: For all skin types including darker tones.
- Nd:YAG Laser: Safe for all skin types especially darker skin tones but may require more sessions.
- Ruby Laser: One of the oldest laser types; effective on light skin and fine hair.

Laser Hair Removal Myths
There are many myths surrounding laser hair removal that can scare some people off. Here are a few busted:
- Myth: Laser hair removal is permanent.
- Fact: While it reduces hair growth significantly, maintenance sessions may be required as some hair can grow back over time.
- Myth: It works on all hair colours.
- Fact: Best results for dark hair with fair skin as the contrast is needed for the laser to target the melanin effectively.
- Myth: It’s too painful.
- Fact: Most people describe it as mildly uncomfortable, like a rubber band snap. Cooling devices and numbing creams can help reduce the discomfort.
Customisation and Flexibility
One of the best things about laser hair removal is the customisation. Treatments can be tailored to address specific concerns, like targeting facial hair or delicate areas like the bikini line. With the latest technology, different skin tones and types can be treated, making it more accessible to more people.
Conclusion
Laser hair removal is a great option for those who want to remove hair and have long term hair reduction. It’s not without its challenges but the benefits far outweigh the drawbacks for those who want smoother skin with less effort. By choosing the right clinic, preparing well and following aftercare instructions you can get the most out of your laser hair removal treatment.
