What are ‘collarium’ sunbeds? Here’s why you should stay away
A collarium sunbed emits both UV radiation and a mix of visible wavelength colours to produce a pink or red light.
- A collarium sunbed emits both UV radiation and a mix of visible wavelength colours to produce a pink or red light.
- Like an old-school sunbed, the user lies in it for ten to 20 minute sessions to quickly develop a tan.
Why were sunbeds banned?
- Commercial sunbeds have been illegal across Australia since 2016 (except for in the Northern Territory) under state-based radiation safety laws.
- Their dangers were highlighted by young Australians including Clare Oliver who developed melanoma after using sunbeds.
- Research shows people who have used sunbeds at least once have a 41% increased risk of developing melanoma, while ten or more sunbed sessions led to a 100% increased risk.
How are collarium sunbeds supposed to be different?
- Australian sellers of collarium sunbeds imply they are safe, but their machine descriptions note the use of UV radiation, particularly UVA.
- UVA is one part of the spectrum of UV radiation.
- Evidence shows all types of sunbeds increase the risk of melanoma, including those that use only UVA.
Collagen claims
- One particularly odd claim about collarium sunbeds is that they stimulate collagen.
- Collagen is the main supportive tissue in our skin.
- The reactive oxygen species generated by UVA light damage existing collagen structures and kick off a molecular chain of events that downgrades collagen-producing enzymes and increases collagen-destroying enzymes.
- Over time, a build-up of degraded collagen fragments in the skin promotes even more destruction.
What about phototherapy?
- The anti-collagen effects of UVA can also be used to treat thickened scars and keloids.
- Side-effects of UV phototherapy include tanning, itchiness, dryness, cold sore virus reactivation and, notably, premature skin ageing.
So what happens now?
- It looks like many collariums are just sunbeds rebranded with red light.
- Queensland Health is currently investigating whether these salons are breaching the state’s Radiation Safety Act, and operators could face large fines.
