Stretch Marks — Conditions

What is Stretch Marks?

Linear scars caused by collagen rupture in the dermis due to rapid body changes

Occur during pregnancy, growth spurts, or rapid weight changes. Initially red or purple, they gradually fade to white over time.

Main causes & characteristics

When skin expands rapidly over a short period — as during pregnancy, growth spurts, or sudden weight changes — the collagen and elastic fibers of the dermis are known to be unable to withstand the tension and rupture, resulting in linear marks. Hormonal changes are also cited as a factor that affects the elasticity of the dermis. They tend to appear red or purple initially, then gradually fade to white over time.

How to manage

Management is known to be comparatively easier during the early stage when the marks are still red, so consistent moisturization and skincare are recommended. Products containing ingredients known to support dermal elasticity are sometimes used as supplementary care. If the marks are extensive or a concern, consulting a dermatologist to determine the appropriate course of management is advisable.

Good to know alongside

Is frequently discussed alongside collagen, the dermis, elastic fibers, and scarring. Early-stage care while the marks are still red tends to be more commonly discussed than care after they have faded to white.

Everyday care tips

During periods of rapid weight or body shape change, applying ample moisturizer to the affected areas to maintain skin suppleness may be helpful.
