Aerolase: Gentle, Effective Laser Treatment for Every Skin Type
Aerolase delivers laser energy in 650 microseconds, short enough to treat acne, redness and pigment safely on Fitzpatrick I to VI skin. Here is how it works.
If you have ever been told your skin is too dark for laser treatment, you were not being brushed off without reason. For decades the advice in aesthetics was that deeper skin tones carried too much risk of burns and lasting pigment change, so patients with Fitzpatrick type IV, V and VI skin were steered toward creams instead.
That was sound guidance for the lasers of the time. It is no longer the whole story.
The Aerolase Neo Elite changed the math with one specification: a pulse lasting 650 microseconds. It reads like a footnote on a spec sheet. It is actually the reason one device can treat active acne on a Fitzpatrick VI patient in the morning and Arizona sun damage on a Fitzpatrick II patient that afternoon, at the same wavelength, with no gel, no contact tip and no numbing cream.
The 650 Microsecond Pulse, Explained Without the Physics Degree
Every aesthetic laser delivers energy that a specific target absorbs: melanin in a brown spot, hemoglobin in a dilated vessel, the inflammation behind a breakout. Getting energy into skin was never the hard part. The hard part is heat that lingers. A target absorbs energy, heats up, and that heat spreads into nearby tissue.
If the pulse is still firing while heat spreads, the surrounding skin cooks along with the target. In melanin rich skin, where the whole epidermis absorbs energy readily, that is what produces burns and stubborn post inflammatory hyperpigmentation.
A microsecond is one millionth of a second. Aerolase delivers its energy in a 650 microsecond burst, shorter than the time surrounding tissue needs to carry heat away. The pulse is over before neighboring skin registers anything.
Older 1064nm systems spread the same wavelength across pulses hundreds of times longer, which is why they rely on cooling gels, chilled tips and cryogen spray. Aerolase needs none of it, and nothing touches your face.
What Fitzpatrick Type Means, and Why It Stopped Being a Wall
The Fitzpatrick scale sorts skin into six types by how it behaves in the sun, from type I, which always burns and never tans, through type VI, which is deeply pigmented and rarely burns. In laser medicine it has always doubled as a risk chart.
| Fitzpatrick Type | Typical Sun Response | Traditional Laser Concern |
|---|---|---|
| I and II | Burns easily, tans little | Low risk, widest device options |
| III | Sometimes burns, tans gradually | Low to moderate risk |
| IV | Rarely burns, tans easily | Moderate risk of pigment change |
| V and VI | Rarely or never burns, deeply pigmented | Historically high risk, often declined |
Aerolase is used across the full range, type I through type VI, which is precisely why we chose it. Many of the people who book Aerolase laser sessions in Lake Havasu City were turned away somewhere else, or were treated anyway and left with a darker patch that took months to fade.
Tone is still only one variable, so every first visit includes a test area. Recent sun exposure, self tanner and photosensitizing medication shape the plan more than your Fitzpatrick number does.
What Aerolase Is Actually Used For
The 1064nm wavelength reaches several targets at once, so one pass often does more than one job.
- Active acne. Energy targets the bacteria and inflamed oil glands behind breakouts, making it an option for stubborn adult acne that topicals and antibiotics have not settled.
- Redness and flushing. Hemoglobin absorbs this wavelength, so the small dilated vessels behind rosacea and persistent facial redness can be treated without contact.
- Melasma and dark spots. Pigment is broken up gradually rather than blasted, which matters most where aggressive removal backfires.
- Sun damage. Brown patches earned on the water respond well, usually darkening before they flake away.
- Fine lines and early laxity. Controlled dermal heating stimulates new collagen across a series.
- Unwanted hair. 1064nm is the wavelength most often chosen for hair removal on deeper skin tones.
- Texture and acne scarring. Here the Era Elite adds 2940nm fractional resurfacing when the surface needs remodeling.
What a Session Actually Feels Like
Most appointments run 15 to 30 minutes. You are given protective eyewear, the area is cleansed, and that is the entire preparation: no numbing cream, no waiting, no cold gel. The handpiece glides just above the skin without touching it, and the sensation almost everyone describes is a quick warm snap, closer to a rubber band flick than pain.
Afterward you look lightly flushed, and that settles within hours. There is no peeling to hide, so people come in on a lunch break and go back to work. Daily mineral sunscreen is non negotiable here, and skip the hot tub and hard workouts for 24 hours. Most plans run three to six sessions, three to four weeks apart.
Where Aerolase Fits, and Where It Does Not
Honesty is more useful than enthusiasm. Aerolase is excellent at clarity: acne, redness, pigment, tone and early textural change. It is not a facelift, it does not replace lost volume, and real laxity is better served by a tightening device.
Deep tethered scars usually need fractional resurfacing. Weighing it against the rest of the laser and light treatment options at Desert Oasis Wellness and Med Spa is what a consultation is for.
Some situations mean waiting: active infection or a cold sore in the area, isotretinoin within roughly six months, pregnancy, a fresh tan or sunburn, and photosensitizing medications. Bring your medication list. When cost is the sticking point, Cherry and CareCredit financing are available.
Frequently Asked Questions
Is Aerolase really safe for dark skin, or is that marketing?
It comes down to pulse duration, not a claim. Because energy is delivered in 650 microseconds, heat cannot spread from the target into surrounding epidermis, which is the mechanism behind burns and pigment change in melanin rich skin. A test area at your first visit confirms how your skin responds.
Does it hurt enough to need numbing cream?
Almost never. Most patients report brief warmth or a light snap, and no anesthetic, gel or contact tip is used. Era Elite resurfacing passes feel warmer, but most people tolerate both comfortably.
How soon will I see a difference, and how many sessions?
Redness often calms within three to seven days of the first session, and brown spots darken before flaking away over one to two weeks. Collagen changes build slowly, with the fullest result around eight to twelve weeks after a series of three to six visits. Individual results vary.
Can I have it done during an Arizona summer?
Yes, with discipline about sun. Treated skin is more sun sensitive, and a fresh tan or sunburn means postponing. Daily mineral sunscreen, a hat and shade for the first week or two make summer treatment reasonable rather than risky.
