What is LED Light Therapy for Skin?
LED light therapy for skin, also known as photobiomodulation therapy or low-level light therapy (LLLT), is a non-invasive treatment that utilizes specific wavelengths of light for skin treatments to improve various skin conditions. LED stands for Light Emitting Diode.
LLT therapy works by emitting specific wavelengths of light, typically in the visible spectrum, which penetrate the skin at different depths and are absorbed by cells. Different wavelengths target different skin concerns:
-
Red LED light (620-750 nm): Stimulates collagen production, reduces inflammation, and promotes wound healing. It's often used for anti-aging purposes, to improve skin texture, and to reduce the appearance of signs of aging.
-
Blue LED light (405-495 nm): Targets acne-causing bacteria (Propionibacterium acnes) that contribute to acne breakouts. It helps to minimize acne lesions, prevent future breakouts, and reduce inflammation.
-
Amber light (590-620 nm): Stimulates collagen and elastin production, promotes circulation, and helps to improve skin tone and texture. It can also reduce redness and inflammation.
-
Green light (495-570 nm): Targets melanocytes, the cells that produce melanin, helping to reduce pigmentation and improve skin tone. It also has a calming effect on the skin and can help to reduce redness.
-
Yellow light (570-590 nm): Helps to reduce redness, inflammation, and swelling, making it beneficial for sensitive or rosacea-prone skin. It also promotes lymphatic drainage, improving circulation and detoxification.
LED light therapy is typically administered in sessions lasting from a few minutes to half an hour, depending on the device and the specific skin concern being addressed. It's a painless and non-invasive procedure with minimal risk of side effects, making it suitable for all skin types. LLT therapy can be performed as a standalone treatment or in combination with other skincare treatments for enhanced results.
How is Light Therapy Performed on the Skin?
