| Rejuvi "s"
Facial Sun Block is a unique product utilizing micronized titanium dioxide
and micronized zinc oxide - physical sunscreens - the latest in sun
protection technology. Modern research reveals that short wavelength UV rays
(UVB) are responsible for sun burn and sun tan and the traditional sun
protection factor (SPF) mainly refers to protection against UVB rays. In
contrast, long wavelength UV rays (UVA) penetrate deep into the skin and are
the main cause of premature skin aging and for skin cancer. Therefore, UVA
protection is critical when considering a good sun protection product. The
combination of two physical sunscreens as well as a PABA-free organic
sunscreen (low concentration) enables Rejuvi "s" Facial Sun Block
to provide superior protection from both UVB and UVA rays.
