Microneedling for old stretch marks: what to know

Stretch marks are areas where the skin has changed after stretching, such as during growth, pregnancy, or changes in body size. Older marks are often lighter and flatter than newer marks. A pen with fine needles creates controlled micro-injuries in the surface layers, prompting a healing response that can gradually improve uneven texture and the contrast between the mark and nearby skin. The change is gradual, and the colour, depth, location, and age of the marks affect what can be achieved.

Arrange a skin assessment before treatment so the clinician can confirm that the marks are suitable and check for active irritation, infection, or a tendency to form raised scars. Discuss medicines, retinoids, recent tanning, and any history of slow healing. Afterward, follow the cleansing and moisturising instructions, protect the area from sunlight, and avoid picking or rubbing peeling skin. More than one session may be suggested, with time between sessions for recovery. You can read about [Microneedling](/treatments/aesthetic-procedures/microneedling/) and the [Microneedling Pen](/technology/microneedling-pen/) to understand the treatment and device.

Mild redness, warmth, sensitivity, or pinpoint bleeding can occur after treatment. Contact the treating clinic if pain is worsening, swelling spreads, the skin becomes increasingly hot, pus appears, or you develop fever. Seek prompt advice for blistering, marked darkening, or a new raised scar. These changes need assessment rather than another session.

Ask which areas and depths are appropriate, how many visits may be reasonable, what recovery usually looks like for your skin tone, and whether another option such as [Fractional Laser Treatment](/treatments/laser-and-energy/fractional-laser-treatment/) or [RF Microneedling](/treatments/laser-and-energy/rf-microneedling/) fits your goals.
