Can Red Light Therapy for Face Cause Hyperpigmentation?

Red light therapy (RLT) for face has gained popularity for its ability to rejuvenate skin, reduce inflammation, and promote healing. From at-home devices to professional treatments, it’s widely used to combat fine lines, acne, and uneven skin tone. But can this light-based treatment also cause unwanted skin darkening?

Since hyperpigmentation is often linked to sun exposure, it’s natural to wonder whether red light therapy could have a similar effect. In this article, our experts at Rojo Light Therapy US will dive into the science behind RLT and whether it poses a risk for hyperpigmentation or if it might actually help prevent it.

What is Hyperpigmentation?

Hyperpigmentation is a common skin condition in which certain areas of the skin become darker than the surrounding tissue. This occurs due to an overproduction of melanin, the natural pigment that determines skin, hair, and eye color. While hyperpigmentation itself is not harmful, it can be a beauty concern for many individuals.

Several factors can trigger excess melanin production, including:

• Sun Exposure – Ultraviolet (UV) radiation stimulates melanocytes (the cells that produce melanin), leading to sunspots or freckles.
• Hormonal Changes – Conditions like melasma are linked to hormonal fluctuations, particularly during pregnancy or with oral contraceptive use.
• Post-Inflammatory Hyperpigmentation (PIH) – Skin trauma from acne, burns, or irritation can leave behind darkened patches.
• Medications and Medical Conditions – Certain drugs such as antibiotics and chemotherapy agents and medical conditions like Addison’s disease can contribute to uneven pigmentation.

Can Red Light Therapy for Face Cause Hyperpigmentation?

Since excessive light exposure, especially from UV rays, is a well-known trigger for hyperpigmentation, it’s understandable why some may worry that light-based therapies, including red light therapy for face could have similar effects. However, not all light wavelengths interact with the skin in the same way. 

Unlike UV light, which penetrates the skin and damages DNA, red and near-infrared light work at a cellular level to support healing and regeneration.

So, the short answer to this query is no, red light therapy for face doesn’t cause hyperpigmentation. In fact, studies suggest it can actually help reduce existing pigmentation issues. Here’s why:

• Red light does not stimulate melanin overproduction

Unlike UV rays from the sun, red and near-infrared wavelengths do not trigger melanin production. Instead, the treatment increases the production of collagen and elastin, two essential proteins that maintain skin's firmness, elasticity, and overall health. 

• RLT can improve hyperpigmentation

Research has shown that red light therapy improves mitochondrial function, allowing a more efficient cell turnover process in the skin. Red light therapy also helps decrease inflammation. Together, these benefits can help fade dark spots caused by post-inflammatory hyperpigmentation (PIH), sun damage, and melasma. 

While red light therapy for face doesn’t cause hyperpigmentation, there is still a risk of experiencing adverse effects such as irritation, redness, and a slight tingling on the skin. 

Who Should be Cautious in Using Red Light Therapy for Face?

Certain individuals should exercise caution or consult with a healthcare professional before undergoing red light therapy for face. This includes those who are:

• Photosensitive Individuals: Those with heightened sensitivity to light, such as individuals with systemic lupus erythematosus or those taking photosensitizing medications (e.g., certain antibiotics, antipsychotics), may experience adverse reactions to light-based therapies.
• Pregnant Women: Although there's limited research on the effects of RLT during pregnancy, it's advisable for pregnant women to consult with their healthcare provider before starting treatment.
• Individuals with Active Skin Conditions: Those with conditions like eczema or psoriasis should seek medical advice prior to RLT to ensure they’re using the right devices and wavelengths for their treatment. 

How to Maximize Red Light Therapy Benefits for Your Skin While Avoiding Risks

To ensure safe and effective use of red light therapy, consider the following guidelines:

• Consult a Professional: Before starting RLT, especially if you have underlying health conditions or are on medication, consult with a dermatologist or healthcare provider to ensure it's appropriate for you.​
• Use Certified Devices: Opt for FDA-cleared or medically certified RLT devices to ensure safety and efficacy. ​
• Follow Manufacturer Guidelines: Adhere strictly to the recommended usage instructions, including session duration and frequency, to minimize potential risks.​
• Monitor Skin Response: Pay attention to how your skin reacts to RLT. If you notice any adverse effects, discontinue use and consult a healthcare professional.​
• Protect Your Eyes: Always use appropriate eye protection during RLT sessions to prevent potential eye damage.
