If you lose weight, do stretch marks go away?

Stretch marks form when the deeper skin stretches or changes quickly, disrupting collagen and elastin. Weight gain can contribute, but growth, pregnancy, muscle development, hormonal changes and some medicines can also play a part. After weight loss, the marks remain as altered skin texture even when the surrounding volume changes. New marks may look red, purple or darker; older marks often become lighter and more silvery over time.

Aim for steady, sustainable weight changes and moisturise if dryness makes the area uncomfortable, while recognising that creams cannot rebuild deeper damaged skin. A dermatologist can assess the mark’s age, colour and texture before discussing procedures. Options may include microneedling, fractional laser treatment, RF microneedling or carboxytherapy. Results vary, and several appointments or recovery time may be needed depending on the method and skin type.

Seek medical advice if stretch-like lines appear suddenly without a clear change, cover large areas, bruise easily, or occur with muscle weakness or other new symptoms. A clinician can review medicines and health conditions that may affect collagen or hormone balance.

Ask which procedure suits your skin tone and mark type, what improvement is realistic, how many sessions may be considered, and what aftercare and pigment changes to expect.
