Permanent hair reduction with a diode laser

The benchmark of the field is now in Sibiu.

LightSheer® QUATTRO™ — the diode laser from Israel that works in clinics around the world and against which all others are compared in clinical studies. Not an import. Not a copy. The original — and full legs in around 20 minutes, in the hands of the same person who advises you: almost ten years at the laser.

The device

Lumenis LightSheer® QUATTRO™

Plenty of machines have “diode laser” written on the casing. LightSheer is the original: the line from the Israeli manufacturer Lumenis that others are measured against in clinical studies — cleared by the FDA in the United States for permanent hair reduction and CE-marked in the EU. No studio buys a device like this on a whim. At Adrett two handpieces are in use: one for speed across large areas, one for precision and power.

Technical values of the device. What is achievable on your skin is established during the consultation.

On the device
What that means for you
FDA-cleared and CE-marked
The LightSheer line is cleared by the FDA in the United States for permanent hair reduction and carries the CE mark in the EU. That is the difference between a vetted medical device and an import with a handsome brochure.
Vacuum that dampens the sensation
The vacuum draws the skin gently into the handpiece and activates the pressure receptors, which stop part of the heat sensation from being relayed at all. That is exactly why clients who know other devices notice the difference from the very first pulse.
Large handpiece, short sessions
A 22×35 mm spot covers the area in large steps. Underarms take a few minutes, full legs around 20 — a lunch break, not an afternoon.
No gel with the fast handpiece
You are not lying on a layer of cold gel and you do not leave sticky. We work directly on clean, dry skin.
XC handpiece with contact cooling
A chilled sapphire tip, a smaller spot and more concentrated energy. This is where small zones and thick, stubborn hairs belong — the ones for which the large handpiece would be too blunt.
Cooling before, during and after each pulse
The skin is protected continuously, not merely cooled at the end. That is precisely why a properly conducted session is comfortable and leaves no marks.
Its own settings for every zone
Hair on the calf, in the underarm and on the upper lip call for different values — and they get them. The device is not left on one middling setting “for everything”.
Class 4 device, accredited operator
This is not a home device. At Adrett the same person operates it every time — accredited for laser hair removal, with protective eyewear for both of you.

The principle

How the result builds

The laser beam is absorbed by melanin — the pigment that gives hair its colour. The energy becomes heat, the heat travels down the hair to the root, and the root loses its ability to produce a new hair. The surrounding skin, which holds far less pigment, stays cool thanks to the cooling.

The effect is strongest on hairs in their growth phase, because that is when the hair is connected to the root and carries heat to it. At any given moment a portion of the hairs in an area are in exactly that phase — and those are the ones we catch.

That is why sessions sit at calculated intervals: each time we catch a different wave of hairs, exactly when they are vulnerable. With every session the area stays smooth for longer, and what returns is less and finer.

The comfort

Why it is surprisingly easy to sit through

Most devices work with cooling alone: the skin stays where it is, and the energy has to cross the whole layer above the hair. The HS handpiece does something else — it draws the skin gently into the applicator and holds it there for as long as the pulse lasts.

Three things follow at once. The vacuum presses on the pressure receptors, and those block part of the pain signal before it arrives. The stretched skin becomes thinner, so the pigment in it spreads further apart and takes less of the energy away. And the hair root moves closer to the source.

The result: the same effect needs less energy. Less energy means less heat in the skin — a gentler session and a wider safety margin.

Step 1 · Suction The skin is drawn gently into the handpiece. Step 2 · Stretching Pigment spreads apart, the root moves upward. Step 3 · The pulse Less energy reaches exactly the root.

The session

Three steps, no surprises

The first appointment starts with a skin analysis. The settings we work with come out of it — which is why the result is not a matter of luck.

Step 01

Skin analysis and patch test

We establish your skin type and the actual colour of the hair, and go through medication, pregnancy, recent sun exposure and skin conditions. Then a test on a small area and a short pause to observe — only then is the full zone treated.

Step 02

The session itself

The area is shaved beforehand, not waxed. We work systematically, section by section, with the handpiece suited to the zone. Underarms take a few minutes, full legs around 20. Say whenever you would like a pause.

Step 03

Soothing and rules for home

We soothe the skin at the end and you receive the recommendations in writing. The rule that matters most: four weeks without sun or sunbeds, with sun protection on the treated area.

What you get

Why where you go matters

  • The original device from Israel, not a copyLumenis LightSheer® QUATTRO™ — the same device line used in the reference clinical studies, FDA-cleared and CE-marked. Not an unbranded import with the same description in the brochure.
  • Vacuum, not just coolingNot every laser has a vacuum — most devices work with cooling alone. It is the difference between “I gritted my teeth” and “that was surprisingly bearable”.
  • Two handpieces, not one universal tipA large spot for legs and back, a small spot with concentrated energy for the face, underarms and coarse hair.
  • Settings adjusted per zone, every sessionParameters are adjusted as the hair grows finer. A course is not the same button pressed ten times.
  • The analysis and test come before the courseYou learn how many sessions are realistic for your area and whether the laser suits your hair type — before you commit to a course and before you pay anything.
  • One studio, one clientNo crowded waiting room and no rush between appointments. Whoever advises you also treats you.

Who treats you

The device is one half. The experience is the other.

A laser of this class is only as good as the person setting it. The same area, the same client, two different settings — and the result is a different one entirely. So what matters is not only which device stands in the room, but who sits in front of it.

At Adrett the same person is at the device every time. She has worked with lasers for almost ten years and was among the first in Sibiu to do so. That means just about every skin and hair type in this city has already been under her device, long before there was a laser on every corner. That experience is the part no manufacturer ships in the box.

She does both herself: the skin analysis the settings come from, and the session. She is accredited for laser hair removal and takes one client at a time — no crowded waiting room, no rush between appointments, and nobody seeing your skin for the first time.

So you are not simply coming to a device. You are coming to someone who has mastered it — and the device she chose is the very one all others are compared against.

Who it suits

Who the laser is made for

The 805 nm wavelength is regarded as the gold standard for light to medium skin types: it works on the contrast between lighter skin and darker hair. The greater the contrast, the faster the result arrives.

Dark hair, lighter to medium skin

The ideal case — and the one most of our clients fall into. The hair absorbs the energy and the surrounding skin barely does, so we can work with power, effectively and comfortably.

Typical areas: lower legs and full legs, underarms, bikini line, arms, back, chest, nape, upper lip and chin.

Coarse, stubborn hair

Thick hair holds more pigment and, counterintuitively, responds better than fine hair. For it we use the contact-cooling handpiece, which works on a smaller spot with more concentrated energy.

This is where the difference between a properly configured device and one left on a middling preset shows most clearly.

Sensitive zones: face, underarms, bikini

These are the areas where most people give up on other methods. The small handpiece allows short passes and pauses, and the continuous cooling makes the difference exactly where the skin is thin.

We work more slowly and with breaks. You set the pace, and the session can stop at any point.

Darker or tanned skin

Our device works at 805 nm — the wavelength suited to lighter and medium skin tones. We do not treat very dark or freshly tanned skin.

A recent tan is the most common reason to postpone a session: four weeks without sun or sunbeds, before and after. Where you stand, we tell you at the consultation.

White, grey or light blond hair

Without pigment in the hair there is no absorption, so the laser has nothing to heat — with no device on the market, regardless of energy or number of sessions.

We tell you this at the consultation straight away. We would rather have an informed client than a course that cannot work.

When a session is postponed or not performed

Among others: pregnancy and breastfeeding, a recent tan or heavy sun exposure, wounds, infections or active herpes in the treated area, tattoos within the working area, recent isotretinoin treatment, medication that increases light sensitivity, and waxing or tweezing within the past four weeks.

We discuss all of this at the consultation. If you are on medication, please bring the details. Where there is medical doubt we send you to a doctor first — we do not improvise.

The result

What “permanent” really means

After a complete course the area stays smooth for a long time. The hairs that do return are fewer, finer and lighter — often barely visible. Most people hold that result with one or two maintenance sessions a year, and that is that.

The correct term, the one used in the professional literature, is permanent hair reduction: a long-term, stable decrease in the number of hairs that regrow, verified at 6, 9 and 12 months after the course is completed. We use it because it is honest — not because the result is modest.

What depends on you: the exact number of sessions only becomes clear once we have seen your skin and hair. Hormones, the area and hair thickness all change the arithmetic — which is why the first appointment starts with an assessment.

Frequently asked

What you want to know beforehand

Does it hurt?

It feels like a brief, warm snap, similar to an elastic band against the skin. With the vacuum-assisted handpiece the sensation is noticeably milder than with devices that have no vacuum, because the pressure masks part of the heat.

The sensitive areas are the underarm, the bikini line and the upper lip. There we work in shorter passes with pauses. Say at any point if you want us to stop.

How long does a session take?

Underarms a few minutes, the upper lip almost in passing, full legs around 20 minutes. The large 22×35 mm handpiece is the reason it goes so quickly.

In practice: a session for a large area fits into a lunch break.

How many sessions will I need?

Usually between 6 and 10, spaced 4–6 weeks apart on the face and 6–10 weeks on the body. The interval is not arbitrary: it follows the growth cycle of hair in that particular area.

The exact figure depends on the area, the thickness of the hair and your hormonal situation. You get a realistic estimate at the consultation, once we have seen your skin and hair.

How do I prepare?

The area is shaved the day before — the root must stay in the skin, the hair above the surface must not. No wax, tweezers or epilator for four weeks beforehand, because those remove precisely the root the laser needs to find.

No cream, deodorant or make-up on the working area on the day. And no sun or sunbeds in the four weeks before.

What do I do afterwards?

Mild redness and a feeling of warmth usually settle within a few hours. For the first two days, avoid saunas, swimming pools, the gym and very hot water.

Four weeks without sun or sunbeds on the treated area, with sun protection at every exposure. After 1–3 weeks you will see hairs that appear to be growing: these are treated hairs working their way out of the skin. Do not pull them, let them fall.

Does it work on blond or white hair?

No. The laser needs pigment in the hair to turn light into heat. White, grey and light blond hair does not have it and therefore does not respond — not with this device and not with any other on the market.

We tell you this at the consultation, before any booking.

Can it be done in summer?

Yes, provided the area is not tanned and stays covered or protected. In practice, areas covered by clothing are easier to schedule in summer than calves or arms.

If you have just come back from a beach holiday, the session is postponed by four weeks. That is the condition under which we can work safely.

Is it safe?

It is a Class 4 device, operated by the same accredited person who advises you, with protective eyewear for both parties and a patch test on a small area before the first full session.

The usual reactions are temporary redness and slight swelling around the follicles, which settles within hours. Following the rules about sun exposure is the part that rests with you.

What does it cost?

The price depends on the area and its size, and a course is calculated differently from a single session. You are told clearly and in full at the consultation, before deciding anything — with no costs appearing along the way.
