What Causes Stretch Marks?

The skin contains collagen and elastin that help it resist tension and return to shape. When the deeper layer changes faster than it can adapt, linear marks may form. They can occur on the abdomen, breasts, hips, thighs, buttocks, upper arms, shoulders, or back. Newer marks may be red, purple, pink, or darker than nearby skin and may itch; older marks often become pale and less raised. They are not caused by poor hygiene, and they are not spread by contact.

Moisturiser may reduce dryness and friction, but it cannot fully replace altered deeper fibres. Avoid unregulated lightening products and do not scratch itchy areas. If you want cosmetic improvement, a dermatologist can review the mark’s colour, depth, location, and your skin tone before discussing fractional laser treatment, microneedling, RF microneedling, or carboxytherapy. Each option has different recovery needs and potential irritation or pigment effects.

Arrange a medical review when marks arise suddenly without an obvious growth or body-size change, cover a large new area, or occur with easy bruising, muscle weakness, facial changes, or prolonged use of steroid medicines. Pain, heat, discharge, or a separate rash also warrants assessment.

Ask what may have triggered your marks, whether any medicine or hormonal symptom needs review, whether prevention is possible in your situation, and which treatment is safest for your skin tone.
