Light therapy is a skin treatment that uses various wavelengths of light to activate the skin’s natural healing processes. It is capable of penetrating the skin at different depths which can cause various reactions within the skin including treating acne, wrinkles, sun damage, wounds and many other skin problems. The most common types of lights that are used are blue light and red light.
Blue light therapy is most commonly used to treat sun damage, rosacea, and acne. It is able to reduce activity in sebaceous glands (i.e. oil-producing glands in the skin), and kill off specific strains of acne-causing bacteria. Research also shows that blue light can improve the healing process of third degree burns. Blue light treatment sessions can be anywhere from 15 to 90 minutes long, depending on the area being treated and how large it is.
Red light therapy uses low-level wavelengths of light to treat skin issues such as stretch marks, wrinkles, scars and persistent wounds, among other conditions. This frequency of light penetrates deep into the body’s building blocks and boosts blood flow and collagen production. Research has demonstrated that red light therapy activates and stimulates ATP, which improves cellular function, revitalization and repair. Red light therapy helps to stimulate collagen production, increase fibroblast production, increase blood circulation, and reduce inflammation in cells.
Dual therapy involves the use of both blue and red light and is best for those who are looking to reap the benefits of both therapies. Although both red and blue light therapies are effective treatments for various skin conditions, it is important to remember that they are not a “miracle cure” and a holistic approach is recommended.
