Photoaging
The main cause of skin ageing in 80% is the sun. The term photoaging refers to the changes in the skin from chronic exposure to sunlight.
Photoaged skin differs from normally aged skin. It shows dryness, pale yellow tint, rough nodular surface. It is loose, its wrinkles are loose and deep and causes melanchromatic lesions.
Repeated exposure to sunlight causes a variety of undesirable alterations in the collagen and elastin structures at the chorionic levels of the skin, which act cumulatively on the skin over the years.
The intensity of UVA radiation remains constant throughout the year, whether sunny or bad weather, penetrating even glass. It is this radiation that causes photo-aging in the skin.
This is why sun protection must be observed all year round. On the other hand, UVB radiation is more intense in the summer months and is mainly blamed for erythema and skin burns. Both rays are responsible for carcinogenesis.
Skin4sin's sunscreens, have high quality sun filters that protect against UVA and UVB radiation and powerful moisturizing agents that bind and retain moisture in the skin.
