Stretch marks These are light lines on the skin that are caused by sudden stretching of the skin. The most common causes of stretch marks are cyclical weight fluctuations, pregnancy, hormonal disturbances and body growth during puberty. Through the sudden need to fill the skin, collagen networks are formed. Their colour varies with the complexion. Stretch marks are red in the first phase and their colour fades over time.

Their disappearance depends on genetic predisposition - sometimes regular skin care is enough to get rid of stretch marks, sometimes it is necessary to aesthetic medicine treatments.
