What does non-nano mean in a zinc sunblock?
A nano particle will enter the blood stream but a non-nano will not. For that reason, non-nano is safer. Nano comes from the Greek word “nanos” and means “Dwarf.” 1 nanometre = one billionth of a metre, meaning a nanoparticle is a particle smaller than 100 nanometers. Therefore a non-nano particle is larger than 100nm.
What is zinc oxide?
Zinc is a powered mineral that sits on top of the skin. It can stand alone as a sunblock because it is truly effective against UVA, UVB and even UVC rays. It has been widely used in diaper creams because of its safety and effectiveness.
Zinc Oxide Benefits:
According to Dr. Marilynn Syrett, zinc oxide is one of the safest ingredients for protecting the skin from the harmful effects of ultraviolet (UV) rays. UV rays penetrate the skin and damage tissue, speeding up the aging process and drying the skin out. These rays also increase the risk of skin cancer. Sunscreens containing zinc oxide filter out UV rays, keeping them from penetrating the skin and causing cell damage.
Zinc oxide is also effective for healing the skin. It can be used to heal wounds, reduce the tenderness associated with sunburns and soften chapped skin. Jonathan Moore, DPM, notes that people who are zinc deficient typically experience slower wound-healing times. When zinc oxide is applied to the wound area, it provides the body with the extra zinc it needs to repair skin cells. Zinc oxide helps keep the wound area moist and clean.
