LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue.
NASA originally developed it for plant growth experiments on shuttle missions and later found it to have promise for wound treatment. LED light therapy is now used by some aestheticians to help regenerate the skin from aging. It’s also used for acne.
Your healthcare provider uses red or blue light frequencies based on the skincare concern. Red is primarily used for anti-aging, while blue is used for acne treatment.
Safety
- Unlike other types of light therapy, LEDs do not contain ultraviolet rays. Therefore, they’re safe for regular use.
- LED light therapy doesn’t cause burns compared to other anti-aging treatments such as chemical peels, dermabrasion, and laser therapy. It may be safe for all skin colors and types.
- You shouldn’t use LED light therapy if you take Accutane for acne or if you’re experiencing skin rashes.
- Side effects are rare but may include increased inflammation, redness, and rashes.
Convenience
- Office procedures take 20 minutes at a time. You’ll need to go back once a week for up to 10 weeks, then only once every few months.
- At-home LED devices can be used at your convenience without having to go to any appointments. The downside is that the results may not be as dramatic.
Efficacy
- When used as directed, LED light therapy can improve your skin over time. You’ll need maintenance treatments to maintain your results.
- Home devices use lower frequencies and haven’t been proven as effective.
What is LED light therapy?
Light emitting diode (LED) light therapy is growing in popularity in both aesthetician offices and at home. Using varying LED wavelengths, this skincare technique purportedly helps:
- treat acne
- reduce inflammation
- promote anti-aging effects
You may be a candidate for LED light therapy if you have these types of skin care concerns and haven’t gotten the results you want from over-the-counter (OTC) skin products. LED therapy is also safe for all skin colors, and it doesn’t cause any burning.
However, there are a few potential drawbacks. Here are several:
- LED therapy can be expensive.
- The results aren’t guaranteed.
- It’s also not safe if you take certain medications or have an active skin disorder.
