LED Light Therapy for Skin Care

led light therapy skin careLight emitting diodes (LED) were first discovered by NASA to attempt to stimulate plant growth in space. Today, LED lights are used in different wavelengths for a wide range of issues, including to stimulate wound healing, treat acne, collagen stimulation, and several other skin related issues. As an approved FDA treatment, LED light therapy doesn’t have any risk for overexposure or for injuring the eye. As a result of the safety and effectiveness of LED light systems, LED light therapy is used in doctor’s office, salons, and spas. You can also find a growing number of LED light systems designed for use in your home. The following information explains your skin and how LED therapy can help your skin become more healthy.

Light Spectrum

With LED light therapy, different colors of LED light are used because each one penetrates the skin differently. To reduce inflammation, red light is used, while blue light is used as an antibacterial. At the same time, near-infrared light has a stimulating effect on cell activity and increases the production of elastin and collagen. Yellow light is effective at assisting the lymph system detoxify the body, while green light is used to reduce redness and increase melanin production.

The Layers of Your Skin

The ability of light to penetrate the different layers of skin is important because your skin is made up of the following three different layers.

  1. The epidermis is the outer and thinnest layer of skin. The epidermis front-line of defense for your organs against the environment.
  2. The subcutaneous layer is the deepest layer of skin and is made up of fatty tissue. The fatty tissue helps regulate temperature and also protects your internal organs.
  3. The dermis is the middle layer and contains the vital elastin and collagen. Elastin is an elastic tissue responsible for allowing skin to resume its shape after being stretched or contracted. On the other hand, collagen provides structure for the skin. The primary role of the dermis is to provide support and structure for your skin.

What Happens When You Age?

As you get older, the production of elastin and collagen slows down, which is called intrinsic aging. Starting at age 20, you’ll lose approximately 1 percent of the collagen in your skin each year. In addition, this process will speed up as you continue to age. As a result, you will begin to develop wrinkles and experience sagging skin. Although you can’t control intrinsic aging, you can effectively reduce the outside factors, such as sun exposure. In addition, you can use LED light to penetrate your epidermis and treat the dermis to reduce the effects of aging in the following ways.

Wrinkle Correction

To smooth out the fine lines on your face and reduce the appearance of wrinkles, red and infrared LED light is used. As the infrared and red LED light waves penetrate the skin, they stimulate the natural process of producing elastin and collagen. When LED light stimulates the production of collagen and elastin, the skin is plumped. Then the red light has an overall lifting effect by improving texture and tone of the skin.


LED light therapy is also an effective treatment for rosacea. Rosacea is a chronic vascular condition of the skin. With the anti-inflammatory effect of red LED light, it can effectively stop the rosacea from progressing. In addition, this therapy can restore collagen, which will thicken the skin and buffer blood vessels with protection.


When treating acne, two different colors of LED light are used. While the red light decreases inflammation, blue light’s antibacterial properties help kill the acne-causing bacteria.
