UVB is the “Bad or Burn ray” but it is also your tanning ray. It stimulates your melanocytes to release melanin, thus creating a tan.
UVA is your “Gentle ray”. It doesn’t create the tan, but maximizes the color in the skin.
Normal sunlight is 5% UVB and 95% UVA.
Te develop the perfect tan first stimulate and create your base tan in the 10 minute, 2% UVB Orbit Bed. Then maximize the color in the 20 minute, 99% UVA Omega Bed. (2% UVB is better. No burn. Just a gorgeous dark Bronze tan!)
