What should you know about red stretch marks on arms?

Arms can develop stretch marks during rapid growth, strength training, pregnancy or changes in body size. Early striae may be red or purple, slightly indented and itchy. They can occur on the upper arms, shoulders or near the armpits. Their presence does not tell you that a particular exercise or food caused them, and they are not contagious.

Keep the area comfortable with a bland moisturiser and avoid harsh scrubs or tanning. If the marks catch or itch, gentle clothing and regular moisturising may help. For cosmetic concerns, a dermatologist may consider [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/). The choice depends on the marks, skin tone, healing tendency and whether you are pregnant or breastfeeding.

Book a review if arm marks develop rapidly without growth or body change, or if they accompany easy bruising, weakness or prolonged use of steroid medicine. Arrange care for significant pain, persistent itch, bleeding or a separate rash around the lines.

Ask whether the marks are typical stretch marks, whether any medicine could be contributing, which option suits your arm skin, and how to reduce irritation or pigment changes after treatment.
