An Overview Of Sun Damage
Your Skin And The Effects Of The Sun:
Sun damage of the skin, also known as photo damage can be either acute,
as in a sunburn or more commonly, chronic, seen as gradual changes in
the skin caused by an accumulation of sun exposure throughout one's life.
Chronic photo damage results in either a cosmetic change in the skin's
appearance called photo aging, or changes that are of medical and health
concerns such as pre-cancerous lesions and skin cancers. The evidence
is very strong that ultra-violet light is the cause of most of the changes
that we consider to be associated with aging of the skin.
Sunshine, although essential for health and well being, is certainly a
hazard for the skin. For many people it feels good to spend time outdoors
and this makes it difficult to avoid excessive exposure to the sun. Most
of the sun exposure we accumulate throughout our lives, is thought to
be the effect of multiple short periods of time outside. If the ozone
depletion continues this may also increase our lifetime exposure.
Those living in sunny areas are clearly at risk for photo damage, as are
those with occupations that require working outdoors. Activities such
as skiing, sailing, and gardening can contribute to chronic photo damage.
Even one-time sun exposure, causing a tan, results in damage to the skin.
There is no such thing as a 'safe' tan.
Individuals with fair skin are clearly at greater risk although sun damage
can occur in all skin types. Tanning studios are popular amongst many
and this also adds to an accumulation of photo damage.
Smoking is another environmental factor that contributes to premature
aging of the skin. Early recognition of sun damage will provide a better
chance of reversal of the cosmetic appearance as well as reducing the
number of skin cancers.
