An Erbium YAG laser peel is true ablative resurfacing. A 2940nm beam — absorbed almost entirely by the water in your skin — vaporizes the damaged outer layer and heats the dermis below to trigger new collagen. Let's be clear up front: this is a medical procedure, not a facial. There's numbing, there's real downtime, and the skin peels. It's intense because it works.
What if the damage of decades could be lifted away —
one controlled layer at a time?
Your skin is roughly two-thirds water, and the Erbium laser's 2940nm wavelength is absorbed by water faster than almost any other laser — about ten times faster than a CO2. When the beam hits the skin, it flashes that water to vapor in an instant, lifting off the outer layer. That's ablation. A measured amount of heat passes into the dermis underneath, and that controlled injury is what signals your body to rebuild with fresh collagen as it heals. Think of it as sanding and refinishing wood — you take off the scarred, weathered surface and let a smoother one grow back.
The beam fires in pulses, and the water in your skin absorbs it instantly — vaporizing the damaged top layer. This literally turns tissue to vapor, which is why a filtered smoke evacuator runs the entire time, pulling the plume out of the room. A faint "ash" is left on the surface, our cue that the energy landed where it should.
Below the surface, a controlled amount of heat diffuses into the papillary dermis. That measured thermal injury is the whole point — it's the signal that wakes up your fibroblasts and tells your skin to lay down new, organized collagen. We control exactly how deep that goes with energy and spot size.
Over the next several days the outer skin sloughs off and fresh skin re-grows — re-epithelialization usually finishes around day 5. Then the slow part: new collagen keeps building for the next four to six months, so your skin keeps improving in tone, texture, and firmness long after it has healed.
The system runs from a light surface polish to deep resurfacing. These aren't fixed "levels" you select — we set the energy, spot size, and lens to your skin type and your goal. The same number behaves differently on different skin: a gentle setting on fair skin can be the most we'd safely run on darker skin, which reacts more strongly and carries a higher risk of pigment change. So we read these as the starting points for a plan built around you.
The depth of tissue we remove is set mainly by the energy and spot size: with a full 6mm spot, drop a zero off the energy and that's roughly the depth in microns (1000 mJ ≈ 100 microns), and shrinking the spot to 1.5–3mm concentrates the energy to reach deeper into problem spots like crow's feet and the lines around the mouth. How aggressive — and how risky — that same setting is, though, depends on your skin. Darker skin reacts more strongly and is more prone to pigment change, so we run it more conservatively: a larger spot, a single pass, the fractional lens, and pigment-suppressing prep. Every number here is a decision we make for your skin, not a dial we set and forget.
The Erbium handpiece can deliver its energy two different ways, and choosing between them is a big part of tailoring the treatment to you. One resurfaces the entire surface; the other treats only a fraction of it at a time, leaving healthy tissue in between to speed healing.
The full-beam (telescopic) lens treats the entire surface of the area, with the spot size adjustable on the fly from 1.5 to 6mm. It's the most aggressive, most complete approach — the right call for full-field resurfacing, ablating benign pigmented lesions, and contouring scars. More power means more downtime, so we reserve it for the goals that need it.
The fractional lens fires an array of microscopic wounds — a honeycomb pattern at a 10mm spot and about 35% density — leaving healthy skin between each one to re-epithelialize the treated zones quickly. It's the gentlest, most comfortable option, with the least downtime and the fewest side effects, and it's the safest choice for darker skin tones and for feathering and blending into surrounding skin.
Because Erbium removes skin rather than just heating or fading it, it reaches things creams and gentler treatments can't. Pick what's on your mind — we'll tell you straight how the laser handles it, and where its limits are.
Because Erbium targets water rather than pigment, we can treat a broad range of skin tones — types I through V. But that doesn't mean there are no rules. Darker skin holds more pigment that can react to the heat, so types IV and V need pigment-suppressing prep, gentler settings, a single pass, and often the fractional lens. Type VI we don't treat with ablative Erbium — for the richest skin tones we turn to Pixel8 RF microneedling instead. Answer six quick questions for an estimate — we always confirm it in person.
This is the part no one should sugar-coat. After an Erbium peel your skin is genuinely raw, then it reddens, browns, and peels before the new surface arrives. None of that is a complication — it's the healing sequence. Plan your calendar around it: a mild micro-peel needs a couple of low-key days, a deeper treatment needs three to five. Tap through the stages to see exactly how it unfolds.
The laser itself takes about 20 minutes. The care around it — numbing, prep, the smoke evacuator, your aftercare plan — is what makes it safe and gets you the result. Here's exactly what an Erbium peel at Brains & Beauty looks like, with nothing left out.
We apply topical numbing cream and give it 45–60 minutes to work — this treatment needs it. Then we take before photos, put protective eyewear on everyone in the room, cleanse and degrease the skin, and switch on the filtered smoke evacuator. We fire a small test spot and check for the right light "ash" to confirm your settings before treating the full area.
The handpiece is held just off the skin and moved methodically across the area in small quadrants. With Erbium, a single pass is the standard — we cover the whole field once, not over and over. As it vaporizes tissue it creates a plume, so the smoke evacuator runs the whole time to clear it, and we check the "ash" as we go. You'll feel heat and a strong prickling even with numbing; this is an intense treatment, and we pace it to you. Deeper areas like around the mouth and eyes get a more focused, smaller spot within that pass.
We apply a generous layer of occlusive ointment and a cool compress, then send you home with written aftercare instructions. No makeup over raw skin. You'll keep the area moist with ointment, sleep elevated, and stay completely out of the sun. We schedule your follow-up and the next session if you're doing a series.
Expect raw, red skin that turns brown and peels over roughly 3–7 days, with tightness, sensitivity, and possible swelling early on. Keep it slathered in ointment, sleep with your head elevated, use Tylenol (not ibuprofen), and do not pick at the peeling — picking is how you get scars and discoloration. No makeup until you're healed (about day 5–7), no gym, sweating, hot tubs, or pools while healing, and strict zinc/titanium SPF with sun avoidance for 4–6 weeks. Plan a couple of quiet days for a micro-peel, 3–5 for an aggressive one.
An Erbium peel puts real energy into your skin and creates a real wound — done carelessly, it scars and discolors. That's why every patient is screened and cleared before anything is booked. The treatment is performed by an RN or NP certified on the Erbium YAG specifically, who preps your skin, runs a test spot, and controls every setting to your face. We'd rather talk you out of a treatment that isn't right for you than book it. And we'll always tell you the part most ads skip: this one comes with downtime, and it's worth it precisely because it's not casual.
Every patient is medically screened before a single pulse — skin type, sun history, medications, scarring history, and cold-sore risk — and any prep you need is arranged in advance.
We fire a small test pulse and read the "ash" to confirm your skin responds correctly before we treat the full area.
Your concern, skin type, and area set the energy, the spot size, the lens, and how deep we go. We never run a one-size template on your face.
If another modality on our Spectrum platform — like Pixel8 RF microneedling — would serve you better, or pair with Erbium, we'll tell you, because we have the full platform in-house.
The area drives the price — your hands sit at the low end, while the full face and neck run higher. This is a hands-on, time-intensive procedure, and for larger areas it sometimes takes a second set of hands, so it's priced as the medical resurfacing it is — not a quick facial. The face usually warrants a series, since results build with each session, so we offer that as a package. Your exact plan and price are set after we see your skin.
No marketing-speak. The real questions, with the real answers, from people considering an Erbium laser peel.
We'll look at your skin, talk you through the treatment, give you an honest depth-and-downtime estimate, and answer every question.
Book Now →The information on this page is for educational purposes only and does not constitute medical advice, diagnosis, or treatment. Erbium YAG is an ablative medical procedure that removes layers of skin and requires real downtime: expect raw, red skin followed by browning and peeling over roughly three to seven days, along with tightness, sensitivity, and possible swelling. Do not pick or exfoliate the peeling skin. Some concerns resolve in a single session while layered sun damage, scarring, and deeper wrinkles typically require a short series spaced about four weeks apart, with collagen remodeling continuing for four to six months. Risks include but are not limited to prolonged redness, swelling, milia, temporary acne flare, and temporary darkening or lightening of the skin — a greater risk in darker skin tones — and, less commonly, blistering, infection, and scarring, most often associated with picking, sun exposure, or skipped aftercare. Strict sun avoidance and adherence to aftercare instructions are required. Treatment is not performed during pregnancy or nursing, on recently tanned or sun-exposed skin, within one year of isotretinoin (Accutane), or on Fitzpatrick type VI skin for ablative resurfacing; we also screen for active infection or cold sores, keloid or hypertrophic scarring history, certain immune conditions, bleeding or clotting disorders and blood thinners, uncontrolled diabetes, untreated rosacea, and dermal melasma. Candidacy, treatment depth, session counts, and expected outcomes vary by individual and are determined only after an in-person clinical evaluation; individual results vary and no specific outcome is guaranteed.
