Dark spots on skin can take a toll on a person's self-esteem--and with cheeks, the upper lip, and the forehead being the most common areas, it's difficult to mask them. However, LED light therapy can help diminish the appearance of dark spots, which, in turn, will bolster self-confidence.

According to Hollywood Beauty Secrets, LED light therapy (also called photo rejuvenation) has been used by NASA, the U.S. Army and major athletes to encourage speedy healing. Today, LED is used for cosmetic purposes and is known for being an effective (and non-invasive) way to treat age spots and repair the skin overall.

LED uses various colors of light to create an anti-aging effect on the skin. These wavelengths of light stimulate cell activity and create collagen and elastin in the skin, which leads to healthier skin.

LED can help to fade age spots after approximately three to four weeks of daily exposure to LED light. A way to help speed up the fading process is to apply a fading cream daily while undergoing light therapy treatment.

LED therapy can be done at home with an LED light or in a spa or salon. Either way, the concept and the technology are basically the same.

While LED therapy has many advantages when it comes to eliminating brown spots, Light Sound Therapy states that too much light can damage skin, depleting the amount of vitamins A and C in the skin. For these reasons, LED is almost always safer when performed by a licensed practitioner.
