Aging

Collagen and elastin are proteins present in the body that ensure firmness, suppleness, cohesion, elasticity and hydration to the skin. From the age of 25, the natural production of these slows down gradually. The surface of the skin is weakened and loosens and regains its shape less and less after stretching. 

Lifestyle

Skin is exposed to various conditions that have great influence on the formation of wrinkles over time. Lack of hydration, as well as repeated sun exposure without protection, can have devastating effects on premature skin aging. It has also been shown that smoking, lack of sleep, poor diet and lack of antioxidants and essential fatty acids greatly accelerate the formation of fine lines.

Heredity

Some people are born with advantages or disadvantage in relation to the appearance of wrinkles. For example, people with darker skin are less affected due to their high levels of melanin, which protects them from ultraviolet rays. The thickness of the skin is also an important point: the thicker the skin, the less it will be affected by the weakening caused by aging.

Facial Movement

As the name implies, expression wrinkles are caused by facial expressions repeated every day, such as smiles and squinting of the eyes. As the skin ages, the resulting temporary folds fade away less and less, until they eventually become permanent.
