Stretch Marks and Red Light Therapy: A New Approach

Stretch Marks and Red Light Therapy: A New Approach


Stretch marks, known medically as striae, are a common skin concern for many individuals. These marks appear when the skin stretches or shrinks quickly, causing the collagen and elastin, which support our skin, to rupture. As the skin heals, stretch marks may appear. While not harmful, they can be a cosmetic concern for some.

The Emergence of Red Light Therapy

Red light therapy (RLT), also referred to as low-level laser therapy (LLLT), has gained attention as a potential treatment for various skin issues, including stretch marks. RLT uses low wavelength red light to penetrate deep into the skin layers, purportedly enhancing the skin's healing process and improving its appearance.

How Does Red Light Therapy Work for Stretch Marks?

  1. Collagen Production: RLT is believed to stimulate collagen production, which is crucial in improving the skin’s elasticity and overall texture. Increased collagen may help in reducing the appearance of stretch marks.

  2. Skin Repair and Renewal: By enhancing cellular activity and blood circulation, RLT may aid in repairing and rejuvenating the skin, thereby diminishing the visibility of stretch marks.

  3. Reducing Inflammation: RLT can have anti-inflammatory effects, which might be beneficial in managing the redness and inflammation often associated with newer stretch marks.

Research and Effectiveness

Scientific studies into the effectiveness of RLT for stretch marks have shown promising results. Some research indicates that RLT can improve skin texture and reduce the appearance of stretch marks, particularly newer, red-colored ones. However, it's important to note that results can vary, and the therapy might be more effective on certain types of stretch marks than others.

Safety and Accessibility

RLT is generally considered safe, with minimal side effects, making it an attractive option for those looking for non-invasive treatments. However, accessibility can be a concern, as professional RLT sessions can be costly, and the effectiveness of at-home devices varies.

Red light therapy presents an innovative approach to managing stretch marks, offering a non-invasive, pain-free option with promising results. While it may not completely eliminate stretch marks, it can significantly improve their appearance. Individuals interested in RLT for stretch marks should consult with a dermatologist or skincare professional to understand its suitability for their specific skin type and condition.


Scientific research on the effectiveness of red light therapy (RLT) for stretch marks has shown promising results. Clinical studies suggest that light therapy, including red light and infrared light applied using a laser beam, can significantly improve the appearance of stretch marks. This improvement is attributed to various factors such as increased cellular energy, promotion of collagen production, better lymphatic drainage, reduced swelling and inflammation, improved blood circulation, enhanced healing response, and restored elastin fibers​.
