What Are Stretch Marks?

Stretch marks, or striae, are long, narrow streaks or lines that develop on the skin when it is stretched rapidly. They commonly occur during periods of significant growth or weight changes, such as pregnancy, puberty, or rapid weight gain. Stretch marks can appear on various parts of the body, including the abdomen, thighs, hips, breasts, and arms. While they are not harmful, stretch marks can affect the skin’s appearance and lead to self-consciousness.

Characteristics

Stretch marks begin as red, purple, or pink streaks that may feel slightly raised or itchy. Over time, they fade to a silvery-white or skin-toned colour and become less prominent, though they may remain visible as indented lines. The severity of stretch marks can vary, with deeper or wider marks being more noticeable. They often appear in areas where the skin has undergone rapid stretching.

Causes

Stretch marks are caused by the skin’s inability to produce enough collagen and elastin to accommodate rapid changes in body size. This leads to tearing in the middle layer of the skin (dermis), which shows as visible lines on the surface. Factors such as genetics, hormonal changes, pregnancy, rapid muscle growth, or weight fluctuations can increase the likelihood of developing stretch marks. Dehydration and inadequate skin hydration can further compromise skin elasticity.

Our expert treatments target the deeper layers of the skin to stimulate collagen production, improve skin texture, and fade the appearance of stretch marks. By addressing both the colour and texture, we help you achieve smoother, more even-toned skin and renewed confidence in your appearance.
