Photo damaging is a time-lapsed process that begins during childhood.
It is the result of exposure to the sun's rays over both long and
short periods. It can be acute, as in the case of a serious sunburn,
or cumulative, leading to skin hyperpigmentation, (discoloration,
blotches or dark brown patches,) fine lines and wrinkles, loss of
elasticity and in some cases, skin cancer. All of the above are
characteristics generally described as photoaging.
But what to do…since most people find it difficult
to, (or choose not to) avoid the sun.
In point of fact, we all need sunlight to thrive. Light activates
the production of nutrients that we require and regulates mood as
well as the biochemical processes that are vital to maintaining
optimal health and a youthful appearance. However, 95% of the radiation
reaching the earth consists of UVA rays. It is the long lengths
of UVA waves that can penetrate deeper into both the epidermis and
dermis layers of the skin, causing severe structural damage right
down to our DNA. So the key becomes protection rather than deprivation.
