No matter what your body shape or type, most of us will fall victim to stretch marks throughout our lifetime.
Occuring during periods of skin growth, stretch marks are visible lines on the skin, usually the stomach, thighs, buttocks, breasts, and upper arms, that are dark red or purple at first appearance, fading to become white or silver over time.
The skin contains collagen and elastin, proteins that keep it healthy and supple and allow it to stretch and expand as we grow. However, the inner layer of the skin, known as the dermis, produces collagen and elastin at a lesser rate, and when it cannot keep up with the upper layers, this causes small tears in the skin. These tears eventually become stretch marks.
