LED light therapy for skin: Does it work?
LED light therapy is a popular non-invasive skin treatment for acne, sun damage, wounds, and other skin problems.
The treatment uses varying wavelengths of light to trigger the skin’s natural healing processes to repair the skin. Several treatments are necessary to see results.
What is it?
LED stands for light-emitting diode. These lights have been in use since the 1960’s but people have only recently begun to use them as a skin treatment.
However, since then, LEDs have shown promising results in wound healing and human tissue growth.
Different wavelengths of light in LED lights, including blue and red, penetrate the skin at different depths. This penetration may trigger biological processes that help the skin rejuvenate and heal.
Collagen is a protein in the skin and other connective tissues. It plays a role in skin healing. The body produces less collagen as a person ages, which causes the skin to show signs of aging.
Red light also reduces skin inflammation.
Uses and benefits
LED light therapy can help treat a variety of skin problems, including:
- dull skin
- signs of aging, including wrinkles and age spots
- sun damage
- wound healing
- other inflammatory skin conditions
One of the main benefits of LED light therapy is its safety record.LED light therapy has an excellent safety profile.
It does not contain UV rays, which can be harmful to the skin. Therefore, LED therapy is suitable for regular use.
Unlike chemical peels or laser therapy, LED light therapy does not cause burns. The treatment is also safe for all types and colours of skin.
How to use?
During a professional treatment, the dermatologist may ask the person to lie down under LED lights, or they may use an LED wand on the skin.
Each session lasts approximately 20 minutes and up to 10 sessions may be necessary.
After this, a person may need to return periodically for maintenance sessions.
LED light therapy is suitable for use on any body part, including the face, hands, neck, and chest.
