LED Light May Aid Skin

There was a time when no one thought about light bulbs — one blew, you screwed another one in. Nowadays, it’s more complicated, as energy efficiency concerns have given rise to a slew of options, including incandescent, compact fluorescent lights, and light emitting diodes. LEDs are the most expensive option, but they are also the most energy efficient, are getting more cost-efficient, and they are growing in popularity. With this increasing acceptance, concerns have arisen about long- or short-term direct skin exposure—especially since a 2012 SBU study found that contact fluorescent light (CFL) bulbs can harm skin cells due to UV-light emittance.
