The Evolution of Laser Hair Removal | Med Aesthetics Miami
Laser hair removal is a medical-grade treatment that uses concentrated light to disable hair follicles. It has evolved from slow, painful ruby-laser treatments in the 1990s into a fast, well-tolerated procedure that works across all skin tones.
Modern systems like the ones Med Aesthetics Miami uses combine Nd: YAG and Alexandrite technology with built-in cooling, so most clients describe treatment as mildly warm rather than painful.
Rosana Bermejo, ARNP, has led the practice’s laser protocols since founding Med Aesthetics Miami.

What Is Laser Hair Removal?
Laser hair removal is a medical-grade cosmetic treatment that uses concentrated light energy to target melanin, the pigment inside hair follicles. The laser converts light into heat at the follicle, damaging its ability to produce new hair while leaving the surrounding skin unaffected.
This selective targeting is what separates laser treatment from temporary methods like shaving or waxing, which remove only the visible hair shaft.
How Did Laser Hair Removal Begin?
Laser hair removal traces back to 1960, when physicist Theodore Maiman built the first working laser. Lasers existed for over two decades before hair removal became possible, because early devices couldn’t safely target hair without damaging the surrounding skin.
That changed in 1983, when Harvard researchers introduced the theory of selective photothermolysis in the journal Science — showing that brief, precisely timed light pulses could damage a specific pigmented target, like a hair follicle, without harming the surrounding skin.
This discovery became the scientific foundation for virtually every hair removal and dermatology laser developed since then.
The first laser device designed specifically for hair removal, an Nd: YAG system, received FDA clearance in 1995, with additional melanin-targeting laser types receiving FDA clearance in 1997.
New laser hair removal devices today still reach market primarily through the FDA’s 510(k) clearance pathway, the same regulatory process used since the technology’s earliest approvals.
Early devices had real limitations. The table below summarizes what those first-generation systems struggled with:
| Limitation | Why It Mattered |
| Slow treatment speed | Small areas took significantly longer to treat than modern sessions |
| High discomfort | Early devices lacked cooling technology, causing significant pain during treatment |
| Poor results on darker skin | Early lasers couldn’t reliably distinguish hair pigment from skin pigment, raising burn risk |
What Breakthroughs Improved Laser Hair Removal Technology?
Laser hair removal improved as manufacturers developed new wavelengths targeted to different hair and skin combinations, moving well beyond the original ruby laser. The table below traces that progression:
| Laser Type | Key Advancement |
| Ruby laser (1990s) | First commercially available system; limited to lighter skin tones |
| Alexandrite laser | Faster treatment speed; still better suited to lighter skin |
| Diode laser | Improved comfort and broader skin-tone compatibility |
| Nd: YAG laser | Safe and effective on darker skin tones; became the clinical standard for skin of color |
Cooling technology developed alongside these wavelength improvements, allowing modern devices to protect the skin surface during treatment rather than relying on numbing agents alone.
What Laser Systems Does Med Aesthetics Miami Use Today?
Med Aesthetics Miami operates four clinical laser systems across its three locations, each matched to a patient’s Fitzpatrick skin type and hair type during an initial assessment. The table below summarizes the current lineup:
| Laser System | Location | Best For |
| Apogee Elite | All locations | Fair to dark skin, dual Alexandrite/YAG capability |
| Syneron Candela GentleYAG | Aventura | Dark skin, deep ingrown hairs |
| Soprano ICE | Lauderdale-by-the-Sea | All skin types, including tanned skin |
| Aerolase Neo | All three locations | Folliculitis, dark skin, pain-sensitive patients |
This multi-platform approach reflects a significant change since the industry’s early days, when clinics typically offered a single laser type regardless of patient skin tone.
How Satisfied Are Patients With Modern Laser Hair Removal?
Peer-reviewed research supports high patient satisfaction with modern laser hair removal, particularly with Nd: YAG technology. A 2012 study published in the Journal of Drugs in Dermatology found that all surveyed patients with darker skin tones were satisfied with Nd: YAG laser hair removal, reporting a mean satisfaction score of 84.2 out of 100.
An earlier, broader 2003 study published in the Journal of Cosmetic Dermatology found 71% patient satisfaction across ruby, alexandrite, and Nd: YAG laser types, with laser treatment rated favorably compared with both electrolysis and waxing.
How Popular Is Laser Hair Removal Today?
Laser hair removal ranks among the top five most-considered cosmetic procedures in the United States, according to the American Society for Dermatologic Surgery’s 2025 Consumer Survey on Cosmetic Dermatologic Procedures, which also found that dermatologists achieve 95% or higher patient satisfaction in the majority of treatments surveyed.
Demand has grown substantially since the technology’s early years — ASDS-member procedure volume climbed more than 50% between 2012 and 2014 alone, reflecting broader adoption that followed the introduction of safer, more inclusive laser technology.
What’s Next for Laser Hair Removal Technology?
New laser hair removal devices continue to reach the market at a steady pace. A 2020 review published in Lasers in Surgery and Medicine found that laser and thermal devices make up the largest single category of dermatologic devices cleared through the FDA’s 510(k) pathway, ahead of wound-care and light-based devices.
This ongoing pace of clearance is what continues to bring refined wavelengths and improved cooling systems to market.

Frequently Asked Questions
When was laser hair removal first approved for use?
The FDA cleared the first laser device designed specifically for hair removal, an Nd: YAG system, in 1995. Additional laser types targeting melanin in hair received FDA clearance in 1997, including the alexandrite laser, as the technology matured.
How does modern laser hair removal compare to early devices?
Modern lasers use targeted wavelengths and built-in cooling technology, making treatment significantly more comfortable than early ruby lasers. Today’s systems also work safely across a much wider range of skin tones, unlike early devices that posed a higher risk for darker skin tones.
Why does laser hair removal target hair without damaging skin?
Laser hair removal relies on selective photothermolysis, a theory proposed by Harvard researchers in 1983 that shows that brief, precisely timed light pulses can damage a pigmented target, such as a hair follicle, without harming surrounding skin. This principle remains the scientific foundation for hair removal lasers.
How satisfied are patients with modern laser hair removal?
Peer-reviewed research reports patient satisfaction scores as high as 84.2 out of 100 for Nd: YAG laser hair removal in darker skin types. Broader studies across multiple laser types report satisfaction rates around 71%, with lasers rated favorably compared with waxing and electrolysis.
How popular is laser hair removal in the U.S. today?
Laser hair removal ranks among the top five most-considered cosmetic procedures nationally, according to the American Society for Dermatologic Surgery. Demand has grown substantially since the 1990s, with ASDS-member procedure volume climbing more than 50 percent between 2012 and 2014 alone.
Is laser hair removal safe for all skin tones today?
Yes. Modern Nd: YAG and diode lasers are considered the clinical standard for safe treatment of darker skin tones. Med Aesthetics Miami matches each patient to a specific laser system, such as the GentleYAG or Aerolase Neo, based on skin tone during the initial consultation.
Why do some laser systems work better on certain skin tones?
Lasers target melanin, the pigment in hair and skin. Wavelengths like Nd: YAG penetrate deeper and are less absorbed by surrounding skin pigment, making them safer for darker skin tones than shorter-wavelength lasers such as the original ruby laser.
What advances have been made to reduce laser hair removal pain?
Built-in cooling mechanisms and shorter, more targeted pulse durations have significantly reduced discomfort compared to early devices. Combined, these advances make modern laser hair removal considerably more comfortable than treatments from the 1990s.
How does laser hair removal pain compare to earlier methods, and why do some patients feel less discomfort than others?
Compared to early argon and ruby lasers, modern devices use more selective wavelengths and cooling technology that spare surrounding skin from excess heat exposure. Pain perception still varies by skin type, hair color, treatment area, and individual pain tolerance.
How many laser hair removal sessions does modern technology typically require?
Most patients require 6 to 10 sessions to achieve significant, permanent hair reduction, spaced 4 to 8 weeks apart, depending on the treatment area. Modern lasers target hair follicles more precisely than early devices, often requiring fewer touch-up sessions over time.
