What are the theories about the causes of stretch marks?
I- Mechanical stretching theory suggests that the excessive stretching of the skin beyond its limit causes the rupture of the elastic and collagen fibers, leading to the formation of stretch marks.
II- The infectious theory suggests that infectious processes could cause stretch marks.
III- The genetic predisposition theory suggests that certain genes that are determinants for the formation of collagen, elastin, and fibronectin proteins are decreased in people with stretch marks, causing a change in the fibroblast mechanism.

As teorias sobre as causas das estrias são: I - A teoria do estiramento mecânico sugere que o estiramento excessivo da pele além de seu limite causa a ruptura das fibras elásticas e de colágeno, levando à formação de estrias. II - A teoria infecciosa sugere que processos infecciosos podem causar estrias. III - A teoria da predisposição genética sugere que certos genes que são determinantes para a formação de proteínas de colágeno, elastina e fibronectina são diminuídos em pessoas com estrias, causando uma alteração no mecanismo dos fibroblastos.
