Can I use a derma roller on breast reduction scars to reduce them?

Microneedling with a derma roller can potentially improve the appearance of scars, including those from a breast reduction surgery. The process involves rolling a device with small needles over the skin, creating microscopic punctures. This is believed to stimulate collagen production, which can help to fill in scars over time.
However, it's crucial to note that microneedling should only be considered once the scars are fully healed, which usually takes around one year after surgery. Also, this procedure should ideally be performed by a trained professional to reduce the risk of infection and further skin damage.
Before starting any treatment, it's recommended to consult with a healthcare provider or a dermatologist. They can provide personalized advice based on your skin type, the age and severity of your scars, and other factors. In some cases, other treatments such as laser therapy, scar gels, or silicone sheets may be more effective.
