How do you choose the right cosmetic device?
The key factors are your target group and the treatments you want to offer: for hair removal, diode lasers (DEWEON 4LD) or alexandrite/Nd:YAG (AlexDUAL UFO) are the first choice; for skin rejuvenation and tightening, RF microneedling (EUPHEUS) or BroadBandLight (DERMAFORCE BBL PRO); for pigmentation and melasma, the thulium laser TULIX. Under the NiSV, tattoo, pigment and ablative CO2 treatments are reserved for doctors. We will advise you free of charge on which device suits your studio or practice – simply request a quote.
Are your devices also suitable for smaller beauty studios?
Yes. Many of our customers are individual studios or start-ups. We provide financing ourselves through our house bank – with instalments from approx. €130/month (PICOLO S) or from approx. €470/month (DEWEON 4LD diode laser) over a 60-month term, plus VAT. Induction and training are included, so you can get started straight away.
How does the financing work?
You submit a no-obligation enquiry and we check financing, leasing or hire purchase directly through our house bank – on request with no down payment, also for new businesses. You will receive a response within 24 hours. 60-month term, plus VAT; terms depend on the credit check.
Do you offer training on how to use the devices?
Yes. Every device is delivered with an on-site introduction. Through our own SIAC Academy, we also offer training courses, masterclasses and NiSV certification – at a reduced rate for buyers of our devices.
Are the devices CE-certified and safe to use?
Our devices are developed and manufactured in Germany by SIACSKIN MEDICAL, are CE-certified and come with a 2-year warranty. Service, maintenance and spare parts come directly from the manufacturer in Düsseldorf.
DUAL ALEXANDRITE LASER
Who is the dual Alexandrite laser suitable for?
Our dual Alexandrite laser is ideal for all skin types (I–VI) – thanks to the combination of 755 nm (for light skin) and 1064 nm Nd:YAG (for dark skin). Particularly effective for light hair, fine hair structures and superficial pigment disorders.
Can blonde or fine hairs also be removed?
Yes! Thanks to the high light absorption at 755 nm, the laser is also excellent for blonde, reddish or very fine hair – a clear advantage over conventional diode or IPL systems.
What is the advantage over IPL or simple lasers?
The dual wavelength technology allows for individual adaptation to skin and hair type, increases treatment safety and achieves faster, more effective results – even with difficult skin and hair combinations.
VCL LED system (Vertical Contact Light)
What makes the VCL LED system special?
The VCL system uses innovative high-performance LED technology instead of classic laser sources. It was developed specifically for gentle, non-invasive applications – e.g. skin rejuvenation, acne treatment, collagen stimulation and, in particular, effective hair reduction for very light or fine hair.
Is the treatment painful?
No – the treatment is low‑pain, gentle on the skin, and involves no downtime. It is ideal for sensitive skin types or clients who do not want classic laser therapy.
How many sessions are needed?
Depending on your treatment goals and skin condition, 4–8 sessions at intervals of 2–4 weeks are generally recommended.
Which hair types can be treated?
The VCL LED system is the only device in our portfolio that has been specially developed for treating very fine, vellus-like or light-blonde hair – hair types that are difficult or impossible to target with classic lasers such as alexandrite or diode lasers.
Conclusion: If you want to permanently remove light or barely visible hair, the VCL LED system is the perfect solution – gentle, effective and safe. VCL LED is not suitable for dark hair.
PICOLO LASERS (Q-Switch & picosecond)
What are the PICOLO lasers particularly suitable for?
For tattoo removal, the treatment of pigmentation disorders and melasma, and skin rejuvenation. The PICOLO S and PICOLO L work as Q-Switch lasers with nanosecond pulses, the PICOLO XL with ultra-short picosecond pulses – this breaks color pigments down into fine particles that the body can then clear.
Is treatment with the PICOLO laser painful?
The treatment may be slightly uncomfortable, but is usually well tolerated with cooling or local anesthesia.
How many sessions are needed?
That depends on the treatment goal: for tattoos often 4–8 sessions, for pigment issues usually fewer.
BBL (BroadBand Light / IPL 2.0)
What exactly is BBL?
BBL (BroadBand Light) is an advanced form of IPL technology with precise temperature control – ideal for skin rejuvenation, pigmentation spots, rosacea and acne. Compared with standard IPL, BBL works with a more even energy distribution, shorter pulses and higher efficiency. BBL has been a proven technology in dermatology for many years; the DERMAFORCE BBL PRO implements it in modern device technology with 9 interchangeable filters and sapphire contact cooling.
What advantages does BBL offer over traditional IPL?
BBL is faster, safer and more effective thanks to more even energy distribution and individually adjustable pulse duration.
Is there any downtime?
The treatment is non-invasive – mild redness usually subsides after a few hours.
