As an aesthetician with over 10 years of experience in laser hair removal treatments, I am often asked “what is laser hair removal and how does it work?” In this comprehensive guide, I will explain the procedure, benefits, risks, and what to expect during a treatment.
Laser hair removal is a popular cosmetic procedure that uses a focused beam of light to selectively target and damage the roots of unwanted hair follicles. This disables the hair follicle’s ability to regrow, effectively achieving permanent hair reduction over time.
During a laser hair removal treatment, a handheld device is placed directly on the skin. The device emits a laser pulse that passes through the top layers of skin and is absorbed by the pigment located in the hair follicles. This creates heat damage and destroys the follicle’s ability to regenerate hair over time.
Treatments are spaced out every 4-6 weeks with most clients requiring 6-8 sessions for optimal long-lasting results. Touch up sessions may be required periodically to catch stray hairs. Overall about 80% permanent reduction can be expected when following the proper treatment regimen.
Delicate facial areas often treated with laser hair removal include the upper lip, chin, cheeks, neck, and sideburns. It is well suited for targeting stubborn dark terminal hairs that frequently grow on the face and is gentler compared to waxing or electrolysis.
When performed correctly by an experienced technician, facial laser hair removal effectively reduces hair growth without damaging the surrounding skin. For optimal safety and results, always look for FDA-cleared devices designed for use on facial regions.
Common treatment areas on women include upper lips and chin hair. Men often seek treatments for thicker hair on their neck, jawline, cheeks and sometimes the fuller beard area. Proper eye protection is absolutely mandatory when lasering facial hair to safeguard vision.
During a laser session, you will be provided with eye protection to shield your eyes from accidental laser exposure. The technician will use a handheld laser wand to deliver pulses of intense light to each treatment area, typically using a grid-like pattern to ensure full coverage.
You may experience a brief pinching or hot sensation as the laser pulses are delivered to your skin. Your technician can adjust settings as needed to make you more comfortable. The laser device will make a snapping sound each time it generates a pulse of light.
A typical session can take 15 minutes to an hour depending on the body part. Areas with coarser hair growth like the legs or back generally require longer treatments than smaller areas like the upper lip. After the procedure, soothe skin as needed with an ice pack, aloe vera gel, or hydrocortisone cream prescribed by your provider. Avoid sun exposure while undergoing treatments.
You can resume normal activities immediately, though some localized redness or swelling is common and usually resolves within 24 hours. Schedule a follow up 4 to 6 weeks later to continue the process until desired results are achieved. Most people require about 6 sessions but more may be needed for optimal long-term reduction.
Laser hair removal is used mainly for cosmetic purposes to reduce or eliminate unwanted hair in visible regions like the face, underarms, arms, legs, and bikini line. It is also sometimes used to treat excessive hair growth related to hormonal conditions.
This method provides a fast and semi-permanent solution for removing darker, coarse hairs from nearly any area of the body. It is not generally effective on very fine blond, red or white hairs. Best candidates have fair skin and dark hair due to the laser targeting pigment in the follicle.
Common treatment locations clients request include the chin, upper lip, chest, abdomen, back, buttocks, bikini line, legs and arms. Laser hair removal works similarly on men and women alike. Popular treatments for men focus on the neck, shoulders and back due to a predominance of dark rapid hair growth.
Some of the benefits and advantages of laser hair removal over other options include:
· Long lasting results with about 80% permanent reduction in active hair follicles following an initial treatment series. Continued periodic maintenance keeps regrowth at bay.
· Speed and precision treats only the pigmented hair and leaves surrounding skin intact. Large areas can be treated in one session.
· Less repetitive hassle than daily shaving or weekly waxing sessions. Reduces ingrown hairs associated with waxing or shaving.
· Confidence boosting - Most clients report laser hair removal drastically improves their self confidence and freedom to wear clothing without worrying about stubble regrowth.
While laser hair removal effectively provides permanent reduction, it does not guarantee 100% permanent hair loss in every client. The goal is to damage hair follicle tissues beyond repair to prevent future regrowth. For best outcomes, commit to the full initial clearance series plus follow up annually for touch up treatments.
On average, laser hair removal administered properly by an experienced technician can permanently reduce approximately 80% of unwanted hair after the initial treatment series. Remaining hair may continue to grow but will be finer, lighter and less dense. Continued maintenance keeps follicles disabled.
However bodies continually regenerate skin cells and hormones fluctuate, so periodic touch up sessions help disable newly woke up follicles. Diligent annual touch ups keeps reduction stable long term. For these reasons we advise laser provides semi-permanent or essentially permanent reduction rather than literal full permanence.
Laser hair removal devices produce a highly focused beam of intense pulsed light that selectively targets melanin pigment within hair follicles just below the surface of skin. Melanin provides color and also absorbs light. Laser energy reacts with hair follicle melanin, converts to heat and causes thermal damage at the base of hair.
This impairs the follicle's ability to regenerate itself. Damaging the actual stem cells that allow hairs to grow disables production of thick terminal hairs. The surrounding structures and skin are left unharmed. Over a treatment series, the cumulative destruction causes long lasting hair reduction in active follicles.
To safely and effectively treat patients, laser technicians adjust settings based on skin type, hair color and thickness in any given treatment area. Proper calibration helps destroy hair follicles while protecting the epidermis. When performed correctly by an expert, laser hair removal can permanently reduce hair growth without scarring or adverse effects.
If you are tired of daily shaving, waxing or plucking unwanted hair, laser hair removal is generally considered a good, safe option for most skin types when performed by a properly trained professional. This method often provides remarkable, confidence boosting results that keep clients returning annually for touch up sessions.
I typically advise laser hair removal for dark coarse hairs on fair to olive skin types. Clients with darker complexions require expert calibration to safely treat hair follicles without burning delicate melanin rich skin. Blond, red or white fine hairs lack sufficient pigment to absorb the laser light and do not respond as effectively.
Overall laser hair removal is generally considered a good option for those seeking semi-permanent reduction in darker unwanted hairs. When expectations are properly managed for the level of reduction possible (about 80% on average), most clients are extremely satisfied with the results. Just be sure to choose an experienced laser technician for optimal safety and outcomes.
When performed properly by an experienced, certified laser specialist side effects tend to be mild, temporary and localized. However it is important to understand the range of possible side effects before beginning treatment. These include:
· Local swelling, redness and minor irritation lasting 24 to 48 hours around treatment sites. Easily managed with over the counter hydrocortisone cream.
· Dryness or flaky skin that typically resolves within a week post treatment. Gentle moisturizer provides relief.
· Itching around treatment area for a few days afterward. Antihistamines can help relieve itching.
· Changes in natural skin pigmentation around treatment sites ranging from lightening (hypopigmentation) to darkening (hyperpigmentation) have been reported but are not common with today's advanced devices.
· Blistering or burns are rare but can result if laser technicians fail to properly calibrate based on individual skin type and hair thickness. Always confirm your provider has extensive experience using lasers safely across skin types.
When performed correctly laser hair removal side effects should be minimal, temporary redness and irritation around sites that typically resolves untreated within 24 hours. Call your provider promptly about any unusual or excessive reactions for evaluation.
In Conclusion, laser hair removal is an increasingly popular semi-permanent method for reducing unwanted facial and body hair growth. During treatments, laser energy is absorbed by pigment within hair follicles just below skin's surface which disables the follicle's ability to regenerate. Treatments precisely target hairs leaving surrounding tissue intact. Most clients require about 6 sessions for optimal results and continued annual touch up appointments keep new hair growth at bay. When performed properly by an experienced professional, laser hair removal is widely regarded as a safe, effective approach for long-term hair reduction.
