Why Do You Get Stretchmarks?

Question

a Little Confused..

My Friend Said That You Get Them When Your Fat.

But My Other Friend Said That You Get Them as You Grow and The Elasticy in Your Skin.

Why Do You Get Them?

Answer 1

Its simply just adusting to change. Like if ur fat the skin stretches so the body has to deal with it. Or when you grow up the body stretches so it causes stretch marks

Answer 2

either way...you get them when your skin has been stretched (either by growth, weight gain etc)
