Stretch marks are a common skin concern that many experience at some point. Whether they appear after pregnancy, weight fluctuations, or growth spurts, these skin streaks can be difficult to fade. While they don’t pose any health risks, many people seek ways to improve their appearance and achieve smoother, more even-toned skin.
One treatment that has been gaining attention for its potential in skin rejuvenation is Red Light Therapy. Known for its ability to support collagen production and promote skin healing, Red Light Therapy is now being explored as an ideal alternative for reducing stretch marks. But does it work? How can it help improve the skin’s texture and tone?
Let’s examine Red Light Therapy in more detail and consider whether it effectively treats stretch marks.
Stretch marks, also known as striae, occur when the skin stretches or contracts too quickly. This change causes the collagen and elastin fibers in the skin to break, resulting in the formation of scars. Initially, stretch marks appear as red, purple, or dark streaks, but over time, they may fade into a lighter, silvery color.
Common causes of stretch marks include:
Since stretch marks form deep within the skin, they can be hard to treat. Many creams and topical treatments claim to help, but results are often minimal. This is where Red Light Therapy offers a non-invasive therapy to improve skin texture and elasticity.
Red Light Therapy uses low-wavelength Red and Near-Infrared Light to penetrate the skin and work at the cellular level. It enhances circulation, reduces inflammation, and promotes collagen production—an essential protein that keeps skin firm and elastic.
Initially developed for medical and NASA research, Red Light Therapy is now widely used in dermatology and aesthetics. It is recognized for its role in rejuvenation, helping to reduce fine lines, wrinkles, acne scars, and stretch marks.
According to Harvard Health Publishing (2020), Red Light Therapy promotes healing and skin renewal without damaging the skin’s surface. The Stanford Medicine blog (2025) also notes its rising popularity in aesthetic clinics due to its noninvasive nature and broad skin benefits.
The effectiveness of Red Light Therapy for stretch marks stems from its ability to support the skin’s natural healing and renewal processes. Unlike topical therapy, which only targets the surface, Red Light Therapy works from within, reaching deeper layers of the skin.
Collagen is the foundation of healthy, resilient skin. Stretch marks often result from the breakdown of collagen. Red Light Therapy stimulates collagen production, helping rebuild the skin’s structure and improve texture. A study in Lasers in Surgery and Medicine (Barolet & Boucher, 2010) found that low-level light therapy improved the appearance of scars by stimulating collagen production, suggesting a similar potential for reducing the appearance of stretch marks.
A loss of elasticity contributes to the appearance of stretch marks. Red Light Therapy promotes elastin production, which works in conjunction with collagen to maintain the skin’s suppleness and flexibility. As a result, treated areas may feel firmer and more even-toned.
Healthy blood flow is essential for delivering oxygen and nutrients to the skin. By increasing circulation, Red Light Therapy supports the body’s ability to repair damaged skin cells. This improved healing response can speed up the fading process of stretch marks.
The Cleveland Clinic (2022) notes that Red Light Therapy can improve blood flow and reduce inflammation, two essential processes for repairing skin and fading stretch marks.
Fresh stretch marks often appear red or purple due to inflammation in the skin. Red Light Therapy helps calm irritation and reduce redness, making stretch marks blend naturally with the surrounding skin.
Red Light Therapy is a painless and non-invasive treatment. Sessions typically last 10 to 60 minutes, during which a specialized light device is placed over the targeted area. The light is absorbed by skin cells, triggering a series of natural repair processes without causing any discomfort or damage.
Unlike more aggressive treatments, such as laser therapy or microneedling, Red Light Therapy does not damage the skin and does not require downtime. Many people find it relaxing, and since there’s no recovery period, you can go about your day as usual after each session.
While some people notice improvements after just a few sessions, long-term benefits of Red Light Therapy are achieved with consistent treatments over several weeks or months. The exact number of sessions needed depends on the severity of the stretch marks and the person’s skin response. Please don not expect them to disappear.
While Red Light Therapy significantly benefits stretch mark reduction, combining it with good skincare habits can enhance results. Here are a few ways to support your skin’s healing process:
Moisturizing regularly helps maintain skin elasticity and improves the appearance of stretch marks. Look for products containing ingredients such as hyaluronic acid, shea butter, or vitamin E. Consider our Deeply Vital Oil, which helps hydrate, moisturize, and nourish your skin.
Exfoliating removes dead skin cells and promotes a new cell turnover. A gentle body scrub or a dry brush a few times a week can help improve skin texture and allow treatments like Red Light Therapy to penetrate more effectively.
Since collagen production is influenced by nutrition, eating foods rich in vitamins C and A, zinc, and protein can support skin repair and renewal. Drinking plenty of water also helps keep skin nourished and resilient.
Stretch marks are more noticeable on skin that has been sun-damaged. Wearing sunscreen with an SPF of at least 30 helps prevent further discoloration and supports the skin’s healing process. Using a tinted SPF, such as EltaMD, can help prevent additional sun damage and reduce hyperpigmentation.
Red Light Therapy is safe and gentle for most skin types. Unlike harsher treatments that involve damaging the skin, peeling, or irritation, it supports the body’s natural functions rather than stressing the skin.
There are no significant side effects; however, it is always advisable to consult a professional before starting any new treatment. People with certain medical conditions or those who are pregnant should check with a healthcare provider to ensure Red Light Therapy is suitable for them.
As emphasized by Harvard Health Publishing, Red Light Therapy is generally safe for most people and offers a gentler alternative to invasive skin treatments.
