Why is there a sticker included with each item that indicates 30 washes?
The proprietary fluorescent pigments are bonded to the fibers of the material (nylon high affinity and Lycra lower affinity). Each washing removes some of these pigments over time it is natural and accepted. Testing by SunSoul has shown that for the first 30 washes the intensity of therapeutic light that is transmitted remains around 8mW/cm. After 30 washes the spectrometer (which measures light) still shows a high level of transmitted light, but the peak has lessened yet is still very high. What this means is that if we recommended 2 hours/week, you may have to wear it 2.1 hours a week for the same effect. Market analysis has shown that people are wearing SunSoul WAY more than 2 hours/week anyway. The more time in the sun wearing SunSoul products, the better the expected results will be.
