Laser hair removal uses concentrated pulses of light energy from a laser or intense pulsed light (IPL) device to target hair follicles. These light-based treatments work by being selectively absorbed by melanin, the pigment that gives hair its color. 

The laser’s targeted light is absorbed by the melanin in the hair shaft underneath the skin’s surface. This heats and damages the hair follicle to destroy its ability to grow new hairs over time with repeat treatments, though it may take several sessions to see long-term hair reduction.

Common treatment areas for laser hair removal include the face, legs, underarms, bikini line and other body parts. Laser treatments are very effective on darker-pigmented, coarser hairs but may be less successful on fine, light-colored or gray hairs. Most patients see a 60-80% reduction in hair growth…

What is Laser Hair Removal?

Laser hair removal utilizes concentrated laser light energy to safely and effectively reduce unwanted hair. This FDA-cleared treatment works by targeting melanin, the pigment that gives hair its color. 

The laser’s specialized wavelength is selectively absorbed by the melanin within hair follicles beneath the skin’s surface.

Laser hair removal is a non-invasive solution that uses concentrated light energy to safely and effectively diminish unwanted hair growth over repeated treatments. Learn how this cutting-edge technology can transform your hair removal routine through the experts at Ethos Aesthetics + Wellness.

How Laser Hair Removal Works

Laser and intense pulsed light (IPL) devices emit specific wavelengths that are selectively absorbed by melanin, the pigment in hair. This process, known as photothermolysis, heats the melanin within hair follicles through targeted optical pulses delivered to the skin. 

The resulting thermal energy damages the hair follicle stem cells responsible for new hair production. With multiple spaced treatments, this thermal injury prevents regrowth. 

Treatment Effectiveness Varies 

Laser treatments are highly effective for coarse, dark hairs but may be less successful on fine, light or grey hairs. Individual results also depend on one’s Fitzpatrick skin type – the degree of melanin pigmentation affecting light absorption. While dark hair on fair skin absorbs laser energy best, our technicians can still achieve notable reduction for other hair and skin combinations with specialized protocols.

Customized Care Plans

Common areas like the legs, underarms and bikini typically see 5-8 sessions at 4-6 week intervals for holistic results. Less dense regions may need fewer treatments. At Ethos Spa, careful evaluation of each client’s individual traits allows customization of treatment parameters and schedules for optimal outcomes.

Frequently Asked Questions 

laser hair removal treatment on underarm

Does it Hurt?

Most feel no more than mild discomfort with our topical numbing cream

How Long Do Results Last?

After an average 6 treatments, many see permanent or 1-3 year hair reduction with annual touch-ups. 

Which Areas Can Be Treated?

We safely treat all body parts including delicate areas like the face.

How the Laser Treatment Functions

When the laser light energy contacts the hair follicle, it is transformed into thermal energy that heats and destroys the follicle’s hair-forming cells. 

The damaged follicles are then blocked from regrowing new hairs over time. Most patients will require multiple laser hair removal sessions spaced 4-6 weeks apart to effectively treat hair follicles in all growth phases.

Areas Commonly Treated

Some of the most popular areas for laser hair removal include the legs, underarms, bikini line, face and other body parts prone to unwanted hair growth. Laser treatments are highly effective on coarse, dark hairs but may be less successful for fine, light-colored or gray hairs.

Is it Effective?

Clinical studies have found laser hair removal reduces hair growth by 60-80% after an average of 6 treatments. Many clients see even greater hair reduction or permanent removal. Touch-up sessions are sometimes needed due to each follicle’s natural growth cycle, but maintenance appointments are typically further spaced over time.

Safety and Potential Side Effects

When performed by a licensed professional, laser hair removal is very safe for all skin types. Potential mild side effects may include temporary redness, mild discomfort or swelling but typically subside quickly. It’s non-invasive and carries no known long-term safety risks.

The Cost of Laser Hair Removal

Treatment costs vary depending on the number of body areas addressed and extent of the hair removal area. On average, complete body packages range from $300-1000 per treatment session. Over time, laser hair removal proves more affordable than repeated waxing or shaving.

How Does Laser Hair Removal Work

Laser hair removal efficiently reduces hair through selective photothermolysis. This non-invasive FDA-cleared treatment uses concentrated light to target melanin in hairs without harming surrounding skin.

The Science Behind Laser Hair Removal

Laser and intense pulsed light (IPL) devices emit specific wavelengths that dark pigments like melanin strongly absorb. During treatments, these optical pulses are delivered to the skin, heating melanin within hair follicles. The thermal energy damages hair follicle stem cells responsible for new hair regrowth over multiple, spaced treatments.

Effectiveness Varies by Hair & Skin Type

Laser is most effective on coarse, pigmented hairs. Individual results depend on one’s Fitzpatrick skin type – the degree of melanin pigmentation affecting light absorption. While dark hair on light skin absorbs laser energy best, technicians can still achieve notable hair reduction for other combinations with specialized protocols.

Customizing the Treatment Plan

Areas like face, legs and bikini line typically see 5-8 sessions at 4-6 week intervals for extensive, long-lasting results. Less dense regions may require fewer appointments. Technicians customize treatment parameters and schedules based on body site, hair characteristics and response to prior sessions.

Maintaining Results Requires Upkeep

After the recommended course, many find hair regrowth permanently ceases. However, some hair follicles remain dormant and may periodically produce hairs. Annual touch-ups can eliminate these, maintaining a smooth complexion long-term. Consistent measures reinforce optimal laser hair removal outcomes.
