UV Rays and Your Skin

UV Rays and Your Skin

Ultra-violet radiation consists of UVA, UVB and UVC rays, with UVC being the most harmful.  UVC rays are filtered, to a large extent, by the ozone layer of the atmosphere.

UVA RAYS are closely associated with SKIN AGEING.  They are constant from SUNRISE TO SUNSET and throughout the year.  They can also penetrate glass.  This explains why we don’t burn behind glass.  However our hands, for example, will develop age spots from having them on the steering wheel of a car.

UVB RAYS, on the other hand, are closely associated with BURNING.  These rays are strongest during the SUMMER MONTHS, especially from noon to 15h00.   UVB do not readily penetrate through glass.

85% of all skin ageing is caused by exposure to the sun.



There are two options available – chemical sunscreens and reflective sunscreens.

Chemical Sunscreens

Chemical sunscreens contain chemicals that are able to absorb and transmute the energy of the sun.  It is important to note that chemical sunscreens work within the outer epidermis, rather than on the surface of the skin.  Chemical sunscreens, such as spray-on products should therefore always be applied at least 20 minutes before venturing into the sun to allow the chemicals to enter into the outer epidermal layers.  There is growing concern amongst scientists that chemical sunscreens might be harmful in high doses.  It is therefore preferable to reapply a factor 25 when outdoors, than to use a factor 50 or 100.  Making use of a factor 50 on a daily basis is cause for concern, since we are exposing ourselves to a high concentration of chemicals unnecessarily.


Reflective Sunscreens

The more sensible approach to sun care is the use of a REFLECTIVE SUNSCREEN.   A reflective sun screen contains zinc oxide or titanium dioxide particles which act as reflective agents to disperse the sun’s rays off the surface of the skin.


Vitaderm makes use of a high concentration of non-micronized reflective pigments, with low concentrations of chemical ingredients to boost the sunscreen and ensure UVA and UVB protection.



Always apply before going outdoors, before the skin begins to perspire.

If following a skin care routine, always apply your day cream first, followed by the sunscreen.  If using makeup foundation, apply after the sunscreen.

If you are a person who spends much time outdoors, it is wise to visit the dermatologist every year to have any moles checked.  If you notice any changes in moles, such as itching, colour changes or sudden change in size, it is important to seek medical advice immediately.
