The sun gives a sense of well-being and activates the synthesis of vitamin D in the body, but it also carries risks due to the effects of ultraviolet (UV), a component of the solar radiation that is particularly rich in energy and can damage the skin and eyes.
Besides the UV rays, there are some portions of the visible light that cause harmful effects on the skin.
The HEV (High Energy Visible) light is a high frequency light with a wavelength between 400 and 500 nm in the visible spectrum (blue / violet). At the epidermal tissue and dermal level it causes the formation of reactive oxygen species (ROS), responsible for DNA damage and activation of enzymes metalloproteases matrix (MMPs) that degrade the dermal fibres and can cause premature ageing.
High-Energy Visible (HEV) Light is a form of light believed to cause long-term skin damage as significant as UVA and UVB combined.
HEV damage is insidious and long-term. While there may be no immediate signs such as redness or swelling, repeated exposure over time can lead to premature ageing and even skin cancer.
While it is well known that sunlight can age and damage skin, not everyone is aware that sunscreens cannot provide complete protection against harmful UVA, UVB or HEV rays.
The new ZO Oclipse Smart Tone Broad Spectrum Sunscreen SPF 50 protect against harmful UVA and UVB rays and HEV light and help guard skin against photo damage and future signs of ageing.
