What does LED light therapy do?
LED light therapy helps treat a variety of skin concerns and conditions, including:
- Hair loss.
- Mild to moderate acne.
- Rough, scaly, precancerous spots on the skin (actinic keratosis).
- Sun damage.
In some cases, LED light therapy may treat small and superficial basal cell carcinoma (BCC). BCC, a skin cancer, is the most common type of cancer, affecting about 3.6 million Americans each year.
Are there different kinds of LED light therapy?
LED light therapy uses various wavelengths that correspond to different visible colors. Each color penetrates the skin at different depths.
- Blue light affects the uppermost layer of your skin.
- Yellow light penetrates deeper.
- Red light travels further into your skin.
- Near-infrared light penetrates deepest.
Different LED colors do different things. For example, experts believe:
Red LED light therapy may reduce inflammation and stimulate the production of collagen, a protein responsible for younger-looking skin that diminishes with age.
Blue LED light therapy may destroy acne-causing bacteria (P. acnes).
During treatment, skin specialists may use a combination of lights to treat your specific issue. At-home devices may also combine colors.
What are the benefits of LED light therapy?
LED light therapy might:
- Treat acne.
- Reduce fine lines.
- Help with wound healing.
