Laser hair removal has become a popular choice for those looking for a long-term solution to unwanted hair. Unlike temporary methods such as shaving or waxing, laser hair removal offers a reduction in hair growth that can last for years. Here’s everything you need to know about laser hair removal, from how it works to what to expect during and after treatment.
What is Laser Hair Removal?
Laser hair removal is a cosmetic procedure that uses concentrated light (laser) energy to target hair follicles. The pigment in each hair follicle absorbs the laser energy, which damages the follicle and inhibits future hair growth. It’s considered one of the most effective methods for reducing hair growth over time, and it works best for people with light skin and dark hair, although newer lasers have improved outcomes for a wider variety of skin tones. At Aeternum Aesthetics, we use the Lumiere Duo which is an advanced medical grade machine suitable for use on all skin tones.
How Does Laser Hair Removal Work?
Laser hair removal targets melanin, the pigment in hair, which absorbs light energy and heats up. This heat damages the hair follicle, putting it into a dormant state. Since hair grows in cycles, multiple treatments are needed to catch each follicle during its active growth phase (the anagen phase). This is why a series of laser treatments, usually spaced several weeks apart, is necessary to achieve the best results.
Benefits of Laser Hair Removal
Laser hair removal offers a range of benefits, especially for those tired of constant shaving or waxing:
Long-lasting Results
After a series of sessions, hair growth is significantly reduced, with many clients experiencing permanent hair reduction.
Precision
Laser technology can target dark, coarse hairs without affecting the surrounding skin, making it especially effective in treating specific areas.
Speed
Each laser pulse takes a fraction of a second and can treat many hairs at once, making the process quick. Small areas like the upper lip can be treated in minutes, while larger areas like the back or legs may take up to an hour.
Less Hair Over Time
With each session, hair grows back finer, lighter, and sparser, reducing the need for other hair removal methods.
What Areas Can Be Treated?
Laser hair removal is versatile and can be used on nearly every part of the body, including:
- Face: Upper lip, chin, sideburns, and neck
- Arms: Forearms and underarms
- Legs: Full legs or specific areas like calves
- Bikini Line: Including Brazilian or Hollywood laser hair removal
- Chest and Back: For men and women seeking smoother skin
- Abdomen: Targeting unwanted hair on the stomach or lower back
What to Expect During the Procedure
During your laser hair removal appointment, you’ll be asked to wear protective goggles, and the Practitioner will adjust the laser settings based on your skin and hair type. A cooling gel or device may be applied to your skin to minimise discomfort. Each pulse of the laser feels like a warm pinprick or rubber band snap. While some people experience more discomfort in sensitive areas, most find the treatment manageable.
Preparation for Laser Hair Removal
To ensure the best results, it’s important to prepare properly before each session:
Avoid Sun Exposure
Sunburned skin can increase the risk of side effects. Limit direct sun exposure for at least two weeks before and after treatment.
Shave Beforehand
Shave the treatment area 24 hours before your session. Avoid waxing or plucking, as these methods remove the hair root, which is necessary for the laser to target.
Skip Certain Skincare Products
Avoid retinoids, glycolic acid, and other potentially irritating products on the area to be treated for at least a week before your appointment.
Stay Hydrated
Proper hydration can improve your skin’s response to treatment, so be sure to drink plenty of water before your appointment.
Aftercare Tips
After each session, it’s important to take care of your skin to reduce any redness or sensitivity:
Apply a Cool Compress
If you experience redness or swelling, a cool compress can soothe the treated area.
Avoid Heat and Sweat
Stay away from hot showers, saunas, and exercise for 24 hours to reduce irritation.
Use SPF
Since your skin may be more sensitive after treatment, apply sunscreen to prevent pigmentation changes, especially if you’ve treated areas exposed to the sun.
Avoid Tanning and Exfoliation
Wait at least a week before using any scrubs, retinoids, or tanning products on the treated area.
How Many Sessions Do You Need?
Laser hair removal typically requires 6-8 sessions spaced 4-6 weeks apart to achieve the best results. Hair grows in cycles, and lasers are most effective on hair during the growth phase. After the initial series, some people may need touch-up sessions once or twice a year to maintain results, especially on hormonal areas like the face.
Does Laser Hair Removal Hurt?
Laser hair removal is often described as mildly uncomfortable, with some people comparing it to the sensation of a rubber band snapping against the skin. However, most modern lasers now incorporate cooling systems to make the experience more comfortable. At Aeternum Aesthetics, the Lumiere Duo device used is not uncomfortable at all. It has a built in cooling tip and the sensation felt tends to be mostly described as a tingling/warmth but definitely not painful.
Potential Side Effects and Risks
While laser hair removal is generally safe when performed by a trained professional, there are some potential side effects to consider:
- Redness and Swelling: It’s common to experience slight redness and swelling immediately after the session, which usually subsides within a few hours.
- Temporary Pigmentation Changes: Some people may experience temporary darkening or lightening of the skin, especially those with darker skin tones.
- Blisters and Scars: Rarely, blisters or scars may develop if the skin is particularly sensitive or sunburned.
- Ingrown Hairs:For some, laser hair removal reduces ingrown hairs, but others may still experience them as hair sheds.
Working with a licensed, experienced professional reduces the likelihood of complications and helps ensure safe and effective treatment.
How Much Does Laser Hair Removal Cost?
The cost of laser hair removal varies based on the area being treated, your location, and the clinic. Smaller areas like the upper lip are usually less expensive, ranging from £40 to £60 per session. Larger areas like the legs or back can cost £100 to £150 per session. At Aeternum Aesthetics we offer package deals for multiple sessions, making it more affordable if you’re committing to a series of treatments.
Is Laser Hair Removal Right for You?
Laser hair removal can be a great option for those tired of frequent shaving, waxing, or using depilatory creams. It’s ideal for people who:
Have dark, coarse hair (although it’s effective on other types with new laser technology)
Prefer longer-lasting results
Are willing to commit to multiple sessions for best results
However, it’s not suitable for everyone. Laser hair removal may not work well on white, grey, or very light blonde hair since these lack the pigment needed for the laser to be effective. Additionally, people with certain medical conditions or those who are pregnant may need to avoid laser treatments.
Final Thoughts
Laser hair removal is a convenient, long-lasting solution that can significantly reduce the amount of time spent on hair removal. It’s an investment in both time and money, but for many, the results are worth it. To get the best results, work with a qualified provider, follow preparation and aftercare instructions carefully, and be consistent with your treatment schedule. With proper planning and patience, laser hair removal can help you achieve smooth, low-maintenance skin for the long term.
