Is it safe?

To answer that question, we need to first define what "Safe" actually is.

There are many definitions and standards for something to be safe, based on a country's regulations, cultural beliefs and personal preferences.

There are many substances and activities that are poisonous and directly damage our bodies, with no actual benefit, and still millions of people either consider them safe, or still engage with them with the acceptance of risks. Things such as: Alcohol, sugar, fast food, smoking, solar beds, sun exposure for too long, and etc. 

Now that we understand, safety is subjective, we at Beautibeam, define something safe, as something that does not impose any extra risk than other day-to-day activates that 90% of the population engage with on a regular basis.

So in this case, because Beautibeam uses an Ultra-violet/ Blue light LED, we'd compare the safety to natural exposure to the sun, on a regular sunny day.

The light, as a form of energy or matter (scientists haven't decided on which one is the right answer), has a spectrum of wave lengths. The lights with the wavelength of 400 nano meter up to 700 nano meter, we call the visible light. One range below the visible light is called ultra violet, and one range above visible light is called inferred. The shorter the wavelengths of a light radiation is, the more powerful it will be. Now what is the ultra violet light, also known as UV?

Ultra violet lights, range from 100nm up to 400nm which a quite wide range, it will break down to 3 categories: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). When we talk about UV, it's crucial to be specific about which type of UV we're talking about. UVC is the strongest form UV which naturally is blocked by the earth atmosphere and doesn't reach us, UVB is weaker than UVC and it's associated with sun burn and skin cancer, and UVA is the weakest form UV, and it's associated with skin pigmentation.

What Beautibeam uses is a specific wave length of UVA, which is 395 nm, which is the weakest form of UV light, and it's almost blue light. For the reference, solar beds usually use a 365 nm wavelength, with typical 200W lamps. Which people usually need to use for 8-20 minutes straight for 3-5 sessions to be able to see visible results. What Beautibeam uses is 5 watt LED with 395nm wavelength, for only 2-3 seconds, then with an average gap of 3 seconds, for a maximum number of 240 seconds. Tho that the total exposure might be around 240 seconds, but because the gaps in between, it dramatically reduces the impact of the light on the skin.

To put things into perspective Lumina pro's impact during a full set lash appointment is 400 times less than a 10 minute tanning session, and 40 times less than a 10 minute direct exposure to sun. The FDA has approved the use of 395nm UV light for germicidal purposes. It also says that using UV lights below 400nm (the visible spectrum) does not pose a risk to humans. 

Health experts advise 10 minutes of daily low angle sunlight exposure for many health benefits, one of them being the aide in production of vitamin D.
