What should you know about small stretch marks?

Stretch marks form when deeper skin structures change faster than the skin can adapt. They may occur during growth, pregnancy, muscle gain, or weight change, and some medicines or hormonal conditions can contribute. Early marks may feel slightly raised or itchy and look pink, red, purple, or brown; older marks are often lighter and indented. Their size does not reliably show why they formed.

They are not contagious and are not caused by poor hygiene. A sudden widespread change, especially with easy bruising or other new symptoms, deserves medical review to look for an underlying trigger.

Moisturiser can ease dryness or itch, but it does not rebuild stretched skin. Protect exposed areas from sun so colour contrast is less noticeable, and avoid unregulated lightening products. A dermatologist can discuss [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/) after examining the marks. Results vary, and several appointments may be considered.

Seek assessment if marks appear suddenly without an obvious change in body size, cover large areas quickly, itch intensely, or occur with unusual bruising, weakness, or other body changes. See a clinician before using prescription creams during pregnancy or breastfeeding. Cosmetic treatment should follow an examination, especially for darker skin tones where pigment changes can occur after procedures.

Ask whether the marks are typical stretch marks, which options match their colour and depth, what recovery involves, and how pigment changes or irritation will be prevented. Ask whether a medicine or health condition could be contributing.
