Red Light Therapy Masks: A Closer Look at Anti-Ageing Claims
Red light therapy, which involves using LED lights on the skin, has gained popularity in recent years, particularly with the rise of at-home devices like light-up masks. Afshin Mosahebi, a professor in plastic surgery at University College London, notes that while this treatment has been around for some time, its accessibility has expanded from professional clinics to consumer products.
Benefits and Limitations of Red Light Therapy
According to Mosahebi, there is reasonable evidence supporting red light therapy for wound-healing and inflammatory skin conditions such as acne, dermatitis, and psoriasis. This is due to its ability to increase circulation, reduce inflammation, and enhance cell regeneration. However, when it comes to preventing wrinkles, the proof is less convincing.
The theory suggests that red light might stimulate fibroblast cells to produce more collagen, which could lead to thicker, plumper skin with fewer wrinkles. Yet, Mosahebi emphasises that there is no substantial evidence to back up this claim. If the treatment does work, professional sessions are likely to be more effective because they use stronger light intensities compared to at-home masks.
Long-Term Risks and Safety Concerns
Mosahebi also highlights a significant gap in research regarding the long-term use of red light therapy, especially as manufacturers encourage repeated use with masks. We do not know the potential effects of prolonged exposure, including whether it might accelerate skin ageing—since light is a primary cause of ageing—or impact skin cancer risks.
While he believes red light therapy is generally safe, Mosahebi advises that the best strategies for delaying wrinkles involve basic skincare and lifestyle habits. These include maintaining a nutritious diet, drinking enough water, exercising regularly, and using a nourishing moisturiser along with high-protection sunscreen. Without these foundational practices, investing in a red light therapy mask may not be worthwhile.
Alternative Approaches to Anti-Ageing
For those seeking effective anti-ageing solutions, Mosahebi recommends focusing on proven methods rather than relying on unverified devices.
- Prioritise professional treatments for more reliable results.
- Adopt a holistic approach to skincare that includes sun protection and hydration.
- Consult with dermatologists or plastic surgeons for personalised advice.
