Photoaging (US English)
Solar purpura or senile purpura. The fine blood vessels in overexposed skin rupture
quite easily, resulting in slow-
Skin freckles (also named liver spots or age spots) can occur at any age. They are
most common on the fair skin of children and of adults over the age of 55, particularly
on the sun-
Solar comedones. A little more annoying than freckles are solar comedones, pimples
that look like acne but are not related. The blemish is also known as Favre-
The effects accumulate over years and the result depends very much on the frequency and intensity of exposure to UV radiation. While heat, wind, and air pollutants also accelerate photoaging, UV radiation is to blame for about 90% of the symptoms.
Photoaged skin (dermatoheliosis)is the term for the signs and symptoms and photoaging describes the process. Too much sunshine changes the structure of the skin permanently and is responsible for premature skin blemishes such as:
Wrinkles. UV radiation damages collagen fibre. The repair process becomes rather disorganized and collagen fibres form where they shouldn’t, resulting in wrinkles.
Solar elastosis. Damage to collagen triggers additional production of elastin. Excess collagen elastin stretches the skin and forces it to sag and form furrows. The skin of the neck and the upper back are usually the least protected and suffer most.
Stellate or sun scars. Excessive exposure to the sun takes its toll on sweat and oil glands. They are no longer able to function efficiently, thus depriving the skin of moisture. The skin becomes dry, thick, scaly and scars easily. Wounds tend to heal slowly.
