What should you know about getting stretch marks from working out?

Stretch marks, or striae distensae, are lines that form when deeper skin structures are stretched faster than they adapt. Strength training with quick muscle gain can make them visible on the shoulders, upper arms, chest, back, thighs, or hips. Early marks may look pink, red, purple, or brown before becoming lighter and less noticeable. Body growth, genetics, hormonal changes, and weight change can also contribute, so training is not the only possible factor.

Continue exercise at a pace that feels sustainable, moisturise if the skin feels dry, and protect exposed areas from sun so colour contrast is less noticeable. Creams cannot reliably erase established marks. If their appearance bothers you, 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/). These treatments aim to remodel skin, and improvement varies with mark age, colour, and skin type.

Arrange a review if marks appear suddenly without a clear body change, cover broad areas, or occur with easy bruising, unusual weakness, or other new symptoms. Seek advice before using a steroid cream for marks, because prolonged or unsupervised steroid use can thin the skin.

Ask whether the lines fit stretch marks, which option suits their colour and your skin type, how many sessions may be considered, and how to reduce pigment changes after treatment.
