Can Red Light Therapy Cause Melasma?: 1 Minute to Understanding the Connection Between Red Light Therapy and Melasma

Red light therapy (RLT) is increasingly popular for skin rejuvenation, wound healing, and easing inflammation. Unlike more intense light treatments such as lasers or IPL (Intense Pulsed Light), red light therapy uses low-level wavelengths of visible red light, making it generally safer for most skin types with fewer side effects. However, if you have melasma—a chronic skin condition characterized by brown or gray-brown patches, mostly on the face—you might worry about whether red light therapy could trigger or worsen it.

Current dermatological evidence suggests that red light therapy does not cause melasma. In fact, RLT is non-ablative (does not remove skin layers) and delivers energy in a way that is not known to stimulate excessive melanin production (which is what causes melasma). Melasma is mainly triggered by UV exposure, hormonal changes, heat, and inflammation. While intense heat or light can contribute to melasma, the gentle, cool approach of red light distinguishes it from treatments that might be riskier for someone with melasma.

That said, every skin is unique. If you have a history of melasma or hyperpigmentation, it’s wise to consult a dermatologist before starting any new light-based therapy—even ones considered “safe.” A professional can give personal recommendations, and if you’re incorporating RLT at home, follow guidelines closely regarding session time and distance from your skin.

As a designer, I always remind my clients that lighting plays a massive role not just in aesthetics but also in the perception and health of a space. Well-chosen lighting can enhance clarity and mood without harming your skin. The same principle applies: design solutions—whether for a home or your skincare routine—should always prioritize both beauty and safety. When considering new wellness tools for your home, like RLT panels, make sure your choices work harmoniously with your interiors and health goals. Tools such as the Room Planner can help you visualize how these devices fit into your space seamlessly, ensuring both functional and aesthetic alignment.

Tips 1:

If you’re incorporating skincare devices or wellness technology into your living space, consider the overall design narrative: hide cords, select colorways that complement your décor, and allocate placement where daily use won’t compromise the calming atmosphere you’ve curated in your home.

FAQ

Q: Can red light therapy trigger melasma or make it worse?

A: Most studies show red light therapy is unlikely to cause or worsen melasma since it doesn’t emit UV or significant heat. Always consult with a dermatologist for personalized advice.

Q: Is red light therapy safe for people with a history of hyperpigmentation?

A: Generally yes, but seek medical guidance, as every individual’s skin responds differently to light-based therapies.

Q: What are the main triggers for melasma?

A: Sun (UV) exposure, hormonal changes, and, to a lesser extent, heat and inflammation can trigger or worsen melasma.

Q: How can lighting impact wellness at home?

A: Thoughtful lighting design can set the mood, reduce eye strain, and create a soothing environment—important for both mental well-being and skincare routines.

Q: Should I use red light therapy devices at home or seek professional treatment?

A: Both options are available. If using at-home devices, follow instructions carefully and consult a professional if you have any skin concerns.
