LED Light Therapy — Everything You Need To Know

Straight from a dermatologist

Have you heard of LED Light Therapy? Many claim it’s the key to clear, firm skin. We reached out to Dr. Joshua Zeicher the Director of Cosmetic and Clinical Research Department of Dermatology at Mount Sinai Hospital in NYC to get the low down and find out what exactly LED Light Therapy is and how it can improve your skin.

Keep reading to find out the answers to all of your most-asked questions.

What Is It?

“LED light stands for light-emitting diode. This is the technology used to generate specific wavelengths of light” says Zeichner. In dermatology, research has suggested that this type of light therapy can actually provide some beneficial effects to the skin. Different types of light actually help to target specific skin concerns “For example, blue light may help lower levels of acne-causing bacteria, while red light has anti-inflammatory and collagen-building benefits.”

But, how exactly does it work? When LED Light Therapy is used it works by triggering biological processes that work to rejuvenate and heal the skin. For example, the red light triggers collagen production which improves the firmness and elasticity of the skin. For acne-sufferers, it’s a great option as the blue light has been researched to trigger endogenous photodynamic therapy (PDT). This therapy destroys acne-causing bacteria and prevents acne from forming in the first place.

Are at-home devices worth it?

It’s important to remember that in order to reap the benefits of LED Light Therapy the light-source used needs to be at a specific wavelength. For example, extensive research has shown that the optimal wavelengths for skin improvement are blue (415nm), red (633nm), and near-infrared (830nm). If the device you’ve purchased doesn’t reach these wavelengths the reality is that it’s likely not doing much for the skin.

But, there is some hope! According to Dr. Zeichner “at home devices typically are not as powerful enough as those offered in the office setting. However, they are likely to provide some level of improvement and allow consumers to maintain their benefits at home.” So, if you’re looking to maintain then these devices might be worth it but be sure to research first before purchasing.

Here are some suggestions:

Looking to combat eye wrinkles? Try the Skin Inc. Optimizer Voyage Tri-Light Glasses LED Light Treatment for Eyes. It features an easy-to-wear glasses style design so you can treat the eye area effectively. — $175

For an at-home spa experience, try The LIGHT SALON Boost Advanced LED Light Therapy Face Mask. It comes in a soft, pliable silicone design and utilizes red 633nm light to boost collagen production, minimize redness, and even skin tone. — $495

Fight acne the painless way with the LightStim for Acne LED Light Therapy Device. The handheld device uses LightStim MultiWave® patented technology to kill acne-causing bacteria and soothe redness and inflammation. — $169

What skin types benefit the most from this procedure?

Dr. Zeichner suggests “LED light therapy is most beneficial in people who have early signs of skin aging or those with mild acne.” This is because “once the severity of the skin condition becomes worse, it is often difficult to achieve meaningful results without professional treatment.” This is unfortunately the case with a lot of at-home devices. It’s important to always remember that these tools should be seen as supplements to your already healthy skincare routine and not a replacement.

Is it safe?

Yes! LED Light Therapy tools are cleared by the FDA and approved as safe to use. Zeichner says his only concern “would be in a patient. However, as with any new topical or device, if you develop any sort of skin reaction including skin allergies or worsening of facial conditions like rosacea then you should discontinue using the device right away.” Always listen to your skin and take note of any new or adverse reactions.

Long Story Short

Yes, LED Light Therapy actually works! But, it truly depends on the health of your skin and what kind of goals you are trying to achieve. At-home devices can only do so much so make sure to research before splurging on pricey devices.
