TULIX: FAQs on the Thulium and Erbium Fractional Laser
The TULIX is the non-ablative fractional laser from SIACSKIN: 1927 nm thulium for pigment and the skin surface and 1550 nm erbium glass for collagen in the dermis, individually or combined, in one device without consumables and without a shot limit.
Here you will find the answers to the questions practices and studios ask before buying: wavelengths, power, galvo scanner, scan fields, safety in the handpiece, acne, dark circles and scars, software, training, service and monthly installment.
What is the TULIX and which treatments is it designed for?
The TULIX is a non-ablative fractional laser from SIACSKIN that combines 1927 nm thulium and 1550 nm erbium glass in one device. It is intended for melasma, hyperpigmentation, age spots, sun-damaged skin, acne scars, surgical scars, stretch marks, fine lines, enlarged pores and dark circles. Because it does not remove the skin surface, downtime stays low.
The TULIX is aimed at practices, clinics and professional studios that want to cover pigmentation, scars and anti-aging with one device. It works without consumables and without a shot limit, and cloud software documents every treatment.
What wavelengths does the TULIX have and when do you use 1927 nm or 1550 nm?
The TULIX works with 1927 nm from a thulium fiber and 1550 nm from erbium glass, individually or combined. 1927 nm is strongly absorbed by water and acts superficially in the epidermis, where melasma, age spots and a dull complexion arise. 1550 nm penetrates deeper into the dermis and stimulates new collagen formation there, which suits acne scars, wrinkles and stretch marks.
Combined, you treat both skin layers in one session, for example sun-damaged skin with spots and fine lines. On the TULIX you choose the wavelength according to the findings, and the protocol library by Fitzpatrick type helps you get started.
What power, pulse energy and pulse duration does the TULIX deliver?
The TULIX delivers 5 to 30 W of laser power, a pulse energy of 0.5 to 300 mJ and pulse durations of 1 to 25 ms. The fine lower limit allows very gentle settings, for example for melasma or sensitive skin. With higher energies, 1550 nm reaches the deeper layers that matter for scars.
What counts is not the maximum value but the interplay of energy, spot size and density. With a fractional laser, these values determine how deep each microzone reaches and how much area is treated per pass. The TULIX protocol library is organized by Fitzpatrick type, which makes choosing starting values easier.
How fast is a facial treatment with the TULIX and what does the galvo scanner do?
A full face is treated with the TULIX in under 8 minutes. This is made possible by a galvo scanner that places at least 500 spots per second. A galvo scanner steers the beam over movable mirrors and distributes the microzones evenly across the chosen field, instead of each point being placed individually by hand.
For you, that means short appointments and an even pattern without gaps caused by unsteady working. Still allow time in the appointment for cleansing, consultation and, if needed, a numbing cream, because the laser time itself is only part of it.
What spot sizes, scan fields and scan modes does the TULIX offer?
The TULIX works with spot diameters of 50 to 200 µm, scan fields from 1 × 1 to 20 × 20 mm and a scan spacing of 0.1 to 2.0 mm. There are also three scan modes: Line, Random Single and Random Continuous.
Small fields suit the nasal wings, the eye area or individual scars, large fields suit cheeks, neck and décolleté. With the scan spacing you control the density, that is, how much skin is treated per pass. The random modes place the points in a changing order so that neighboring zones are not heated one right after another. This is gentler on the skin, especially in darker skin types.
How do motion tracking and the thermal sensor in the TULIX handpiece prevent overheating?
On the TULIX, motion tracking registers the movement of the handpiece, and an infrared thermal sensor monitors the temperature. Together they prevent the same spot from being treated twice or the skin from overheating.
Double treatment is a common cause of excessive redness, crusting or pigment shifts with fractional lasers, especially at the transitions between two scan fields. Temperature control is particularly valuable in darker skin types and in melasma, because even a little extra heat can trigger new pigment there. The technology does not replace the practitioner's experience, but it catches typical errors in the workflow.
Yes, acne is among the applications of the TULIX, using both wavelengths in combination. On blemish-prone skin, fractional lasers can stimulate surface renewal, refine the skin texture and visually reduce pores. They do not cure the acne itself, and inflammatory or severe acne belongs in medical hands first.
The TULIX is especially strong with the aftermath of acne: with 1550 nm you treat acne scars, with 1927 nm dark marks after healed pimples. Usually expect 3 to 5 sessions at intervals of 4 to 6 weeks.
Can the TULIX improve dark circles and dark shadows under the eyes?
Yes, dark circles are among the applications of the TULIX, treated with both wavelengths combined. 1927 nm brightens pigment-related shadows at the surface, 1550 nm stimulates collagen and can make thin, crepey skin under the eyes look firmer. How much improves depends on the cause: pigment and thin skin respond well, while visible blood vessels and shadows from volume loss respond only to a limited extent.
On the TULIX you use small scan fields and cautious energies for the eye area. The eyes are protected with suitable laser eye shields, and several sessions at intervals of 4 to 6 weeks usually make sense.
Which scars and skin textures does the TULIX improve with 1550 nm?
With 1550 nm, the TULIX treats acne scars, surgical scars, stretch marks, fine lines, wrinkles and enlarged pores. The wavelength penetrates into the dermis, creates fine zones of heat there and stimulates the formation of new collagen. Scars can become flatter and softer as a result, but they do not disappear completely.
Shallow, rolling acne scars and fresh, still red scars respond best. Deep, depressed scars need more sessions or a combination with RF microneedling or an ablative laser. With the TULIX, 3 to 5 sessions at intervals of 4 to 6 weeks are usually standard, and the final result only shows a few months later.
Can I order the TULIX in my studio color, and are there software updates?
Yes, SIACSKIN paints the TULIX on request in one of over 2,000 Pantone colors, at no extra charge. This way the device matches the furnishings and the branding of your practice or studio, which makes a visible difference in the treatment room and in social media photos.
The device also keeps evolving after purchase: software and AI updates are provided free of charge every 14 days. The cloud software with patient records and protocol library thus stays up to date. It is best to clarify your color wish right when you order.
How much does the TULIX cost per month and how can it be financed?
The TULIX is available with financing from approx. €600/month. As a rule of thumb, the monthly installment is around 1% of the net device price over a 60-month term, depending on creditworthiness. Besides purchase, financing, leasing or hire purchase through SIACSKIN's principal bank are possible, also for start-ups.
For your calculation, what counts with the TULIX is that there are neither consumables nor a shot limit. Without material costs per appointment, more of each treatment is left over for the installment. With the SIACSKIN price calculator you can check in advance, using your own figures, from which month the device pays for itself.
What software and documentation does the TULIX offer?
The TULIX comes with cloud software that combines a patient record, automatic documentation of every pulse and a protocol library by Fitzpatrick type. Every session stays traceably saved.
This helps you in several ways: you continue a series with the same or deliberately adjusted values, even when a colleague takes over. You can compare progress in melasma or scars cleanly. And if questions come up, you have complete proof of what was treated and when. The protocol library also makes the first settings easier for beginners, but it does not replace looking at the skin during the session.
Is training included with the purchase of the TULIX and what happens afterwards?
Yes, the TULIX includes on-site training by experts who work on the devices themselves, not by sales staff. You learn the wavelengths, the scan modes and the protocols for typical indications.
Afterwards you deepen your knowledge at the SIAC Academy, for example on pigment treatments, resurfacing protocols and combination therapies. This is especially worthwhile for melasma and darker skin types, because cautious settings and the right sequence of sessions decide the result. For the first treatments, plan test areas and invite your clients back for a check-up.
What warranty, service and approval does the TULIX have?
SIACSKIN gives a 2-year warranty for the TULIX. Maintenance, spare parts and support come directly from Düsseldorf, and a worldwide technician network offers on-site help. The TULIX bears the CE marking under the MDR, and FDA is additionally stated in the device data.
With any laser device, pay attention to who supplies maintenance and spare parts in the long term. With the TULIX both come from the manufacturer itself, so in a service case you do not deal with an intermediary. That shortens the distances when a question about settings arises or a part has to be replaced, and helps keep the device ready for use for a long time.
Which practice or studio is the TULIX worthwhile for?
The TULIX is worthwhile for practices, clinics and professional studios that want to offer pigment treatments and anti-aging profitably, especially for clients with melasma, age spots, acne scars or large pores. Because it is designed for all skin types and causes only low downtime, it also suits clients who want to get back to work quickly after a treatment.
As a complement to an ablative system such as the FRACO CO2 XL, the TULIX handles the gentler treatments while the CO2 laser covers the intensive ones. Those who have mainly worked with IPL or hair removal lasers so far expand their offering with the TULIX to include melasma, pigment and acne scars.
