Red light therapy has taken the skincare world by storm, with celebrities, dermatologists, and beauty enthusiasts swearing by its benefits. Whether used in LED face masks or handheld wands, this non-invasive treatment is known to stimulate collagen production, reduce inflammation, and improve overall skin texture.

But how effective is it really, and what should you consider before incorporating it into your routine? Dr. Kiran Mian, a board-certified dermatologist at Hudson Dermatology and Laser Surgery, breaks down everything you need to know about red light therapy in a recent online article.

How Does Red Light Therapy Work?

“Red light therapy helps to stimulate collagen and rejuvenate the skin without causing thermal damage,” explains Dr. Mian. “It also has anti-inflammatory properties, which can be beneficial for acne-prone and rosacea-prone skin.”

This technology relies on low-wavelength red light to penetrate the skin at a cellular level, triggering mitochondrial activity and boosting the production of adenosine triphosphate (ATP), the molecule responsible for energy in skin cells. This increased energy supports cell regeneration, reduces redness, and promotes a more youthful appearance.

Red Light Wands vs. LED Masks: Which One is Better?

Many skincare devices use red light therapy, but they come in different forms. The two most common options are red light wands and LED face masks. So which one should you choose?

“Both offer similar benefits, but the key difference lies in treatment area and application method,” says Dr. Mian.

• LED masks provide broad-spectrum coverage, making them ideal for treating the entire face in one session.
• Red light wands, on the other hand, offer targeted treatments, making them particularly effective for fine lines, breakouts, and specific problem areas.

“If you’re looking for all-over skin rejuvenation, a mask might be the better option. But if you prefer a more precise, controlled treatment, a red light wand allows for more customization in your routine.”

How Long Does It Take to See Results?

The key to effective red light therapy is consistency. According to Dr. Mian, most people will notice visible improvements in their skin after 8 to 12 weeks of regular use.

“Most red light devices recommend use three to five times per week for about 15 minutes per session,” she explains. “While some people may see subtle changes in as little as four weeks, significant improvements in fine lines, texture, and inflammation tend to develop over two to three months.”

Are There Any Risks?

Red light therapy is considered safe for most skin types, but overuse or improper application can lead to potential issues.

“One of the main concerns is using inappropriate or unregulated devices that may emit excessive heat,” says Dr. Mian. “Red light itself does not produce heat, but some devices incorporate additional heat therapy that can aggravate conditions like melasma or trigger skin sensitivity.”

For safe use, she recommends:

1. Following the manufacturer’s instructions on frequency and duration.
2. Avoiding excessive heat exposure if you have melasma or sensitive skin.
3. Wearing protective goggles if using a high-intensity device near the eyes.

Which Red Light Devices Are Worth the Investment?

With countless red light wands and LED masks on the market, choosing the right device can feel overwhelming. Some of the most dermatologist-approved options include:

• Best Multi-Use: Medicube Age-R Booster Pro – Features six LED light options for different skin concerns, including red light for collagen production.
• Best for Fine Lines: LightStim for Wrinkles – FDA-approved with a wider head for faster treatment and built-in eye protection.
• Best for Travel: SolaWave Advanced Skincare Wand – A celebrity favorite that combines red light therapy with microcurrent technology for on-the-go skincare.

Final Thoughts

Red light therapy is more than just a social media trend—it’s a scientifically backed treatment with real skin benefits. Whether you’re looking to boost collagen, reduce fine lines, or calm inflammation, Dr. Mian emphasizes that choosing the right device and maintaining a consistent routine is essential for achieving the best results.

“While red light therapy can be a powerful addition to your skincare routine, it’s important to set realistic expectations and understand that results take time,” she says. “Pairing it with a well-balanced skincare regimen and professional guidance will ensure you’re getting the most out of your device.”
