The face you are seeing below,is of a 69 year old man who has been consistently driving a truck for almost 28 years. The left side of his face is affected with asymptomatic thickening and wrinkling of the skin.
This affect is due to the Ultraviolet rays, which enter through the window glass and penetrate the epedermis and the upper layer of dermis.
The study was published in New England Journal of Medicine, according to which:
A 69-year-old man presented with a 25-year history of gradual, asymptomatic thickening and wrinkling of the skin on the left side of his face. The physical examination showed hyperkeratosis with accentuated ridging, multiple open comedones, and areas of nodular elastosis. Histopathological analysis showed an accumulation of elastolytic material in the dermis and the formation of milia within the vellus hair follicles. Findings were consistent with the Favre–Racouchot syndrome of photodamaged skin, known as dermatoheliosis.
The patient reported that he had driven a delivery truck for 28 years. Ultraviolet A (UVA) rays transmit through window glass, penetrating the epidermis and upper layers of dermis. Chronic UVA exposure can result in thickening of the epidermis and stratum corneum, as well as destruction of elastic fibers. This photoaging effect of UVA is contrasted with photocarcinogenesis.
Sun is always known to be a damage to your skin, making you age prematurely, but the affect seen on this man is more obvious because only one side of the man’s face is damaged.
Doctors are recommending use of sun protection and topical retinoids and periodic monitoring for skin cancer for curing the damage on this poor old man.
