Stretch marks on bum cheeks: what to know

The buttock and upper thigh area can change during puberty, pregnancy, weight fluctuation, or glute-focused training. Early striae may be raised slightly, itchy, or red, purple, or brown; mature ones tend to be pale and softer. Genetics influence how easily the deeper skin support fibres show this change. Stretch marks are not caused by dirt, and scrubbing will not remove them.

Moisturise after bathing if the skin feels dry, choose clothing that limits friction, and avoid scratching. Gradual changes in training or weight may limit new rapid stretching, though they cannot control every mark. For cosmetic improvement, a dermatologist may evaluate [Microneedling](/treatments/aesthetic-procedures/microneedling/), [Fractional Laser Treatment](/treatments/laser-and-energy/fractional-laser-treatment/), [RF Microneedling](/treatments/laser-and-energy/rf-microneedling/), or [Carboxytherapy](/treatments/aesthetic-procedures/carboxytherapy/). Treatment choice depends on colour, texture, skin tone, and scar history.

Ask for an examination if the marks develop quickly without a clear change in body size, or if they appear with easy bruising, unusual weakness, or other new symptoms. Get care for a separate rash, intense pain, warmth, drainage, or swelling rather than assuming it is part of a stretch mark.

Ask whether the marks are active or mature, whether a procedure could worsen pigmentation or scarring, what aftercare is needed in a friction-prone area, and how progress will be judged.
