What should you know about bum stretch marks?

Stretch marks, also called striae, form when the deeper skin layers stretch faster than connective tissue can adapt. They may begin as pink, red, purple or darker streaks and gradually become lighter, slightly indented lines. Growth, muscle gain, weight change, pregnancy and medicines that affect the skin can contribute. Their presence does not indicate poor hygiene, and they are not contagious.

Moisturiser can reduce dryness and itch, although it does not remove established marks. Avoid harsh scrubbing and tanning, which can make colour differences more noticeable. A dermatologist can assess whether prescription creams, microneedling, fractional laser treatment, RF microneedling or carboxytherapy fit your skin tone, mark stage and expectations. These procedures work by encouraging controlled skin repair; several appointments may be suggested, and results vary.

Arrange a clinical assessment if marks appear suddenly over a wide area, become painful, bleed, or occur with easy bruising, muscle weakness or other unexplained changes. Seek advice before using a strong steroid cream, especially on thin or sensitive skin. A clinician can also check a new rash that resembles stretch marks but is scaly, swollen or intensely itchy.

Ask what type and stage of stretch mark you have, whether any medicine or health change may be contributing, which option suits your skin tone, and how aftercare and sun protection affect the outcome.
