LED light therapy has grown in popularity in the past several years. Its positive image has been boosted by celebrities like Kate Moss and the Kardashians who swear by its results. This skin improvement procedure is receiving plenty of favorable notoriety mainly due to its results – namely that it is typically successful against combating acne and signs of aging, using just light technology.
Combine this with the nifty, fancy gadgets that appear futuristic, and you have the makings for a fashionable beauty treatment. Skin light therapy is especially useful in treating sagging, wrinkling skin, and inflammation, along with acne.
You can choose to have LED light therapy at a dermatologist’s office or you can use a device at home.
You might be wondering how a device that transmits bright light helps you get a clearer and more radiant complexion?
In this blog article, we will explore how LED light therapy works and touch on its primary benefits.
What is LED Light Therapy?
LED stands for light-emitting diode. These types of lights have been used since the 1960s, however, they have only been applied for skin treatment in recent years. NASA originally developed LED lights for plant growth experiments in space.
Navy SEALS have used LED light therapy to help heal wounds. This treatment resulted in improvements of more than 40 percent of musculoskeletal injuries in team members. It also reduced healing time.
LED light therapy can help treat a variety of skin problems that include the following:
- Dull Skin
- Signs of aging, including wrinkles and age spots
- Sun Damage
- Wound Healing
- Other inflammatory skin conditions
LED light therapy has a good record for safety. Unlike chemical peels or laser therapy, LED light therapy does not cause burns. This treatment is also safe for all types and colors of skin. Because it does not contain UV rays, it is safe to undergo LED therapy regularly.
How Does LED Light Therapy Work
LED light therapy uses color wavelengths of visible light that have specific skin benefits. Aging tends to bring about skin disorders or trauma, healthy skin cells are compromised and unable to renew themselves normally.
“The skin uses the light as a source of energy to fuel the repair and rejuvenation of damaged cells, or, in the case of treating acne, kill bacteria,” says facialist to the stars, Teresa Tarmey. “The energy stimulates the production of collagen and elastin, boosts circulation and accelerates tissue repair. During the treatment, you’ll simply lie underneath a light screen while the device does all the work.”
Different wavelengths of light in LED lights, including blue and red, penetrate the skin at different depths. This penetration could trigger biological processes that help the skin rejuvenate and heal.
Medical experts believe that blue LED light reduces activity in the sebaceous glands, which are small oil-producing glands in the skin. This reduction in activity results in the glands producing less oil, possibly improving acne symptoms. The powerful antibacterial properties in this blue light are believed to provide a UV-free alternative for the treatment of eczema and psoriasis.
Blue light may also eliminate a type of bacteria that contributes to acne by causing inflammation. What’s more, animal research indicates that blue light can improve the healing of third-degree burns.
Red LED light has been shown to improve scarring and signs of aging, such as wrinkles. It likely accomplishes this by acting on fibroblasts, which are skin cells that are responsible for collagen production.
Collagen is a protein in the skin and other connective tissues. It also plays a role in skin healing. Your body produces less collagen as you get older. This is what causes wrinkles and other forms of skin aging.
The properties in the red light increase natural hydration levels, shrinks the appearance of pores, regulates oil production, improves circulation, and accelerates skin repair. It is also medically approved to treat rosacea.
Near Infra-Red Light
This is the most deeply absorbed wavelength. It is supposed to increase cell permeability and absorption, smooth lines and wrinkles, improve elasticity, reduce pain and inflammation, accelerate wound healing, and heal cystic acne.
When LED light therapy is used consistently over time, it is thought to penetrate your skin at different depths and cause various reactions in your skin, like fighting acne-causing bacteria, plumping skin, and reducing wrinkles.
Medical experts caution that you may not see results like this right away.
“You can see results from the first treatment, however, we would recommend a minimum course of six (Six what?),” says skincare expert Natali Kelly. “If you would like to supercharge your skin for specific skin concerns, an intensive course of twelve treatments is advised close together.”
For skin conditions like acne, results might not be realized until completing several sessions. People often see positive results at least several weeks after their last treatment. Follow-up sessions may also be necessary to maintain these results.
