Blue light therapy is a skincare treatment that uses varying wavelengths of light, including blue, to treat certain conditions on or just under the skin. It is a noninvasive procedure that is considered pain-free and safe for regular use. Blue light therapy is primarily used for acne treatment, as it targets the sebaceous glands and kills acne-causing bacteria beneath the skin. It can also be used to treat sun damage and premalignant or malignant skin cancer growths. Blue light therapy devices are available for home use and are designed to be easy to use and safe for daily use to treat mild to moderate acne.
Here are some positive aspects of blue light therapy:
- Noninvasive and pain-free procedure
- Safe for regular use and does not contain ultraviolet rays
- Can be used to treat acne, sun damage, and premalignant or malignant skin cancer growths
- Blue light therapy devices for home use are easy to use and can be used daily to treat mild to moderate acne
Here are some negative aspects of blue light therapy:
- Blue light therapy can only treat areas that the light can reach, so it’s typically used to treat conditions present on, or just underneath, the surface of the skin
- To treat a condition, it takes one to four treatments for actinic keratosis (precancerous sun spots), with annual maintenance
There are no specific ingredients or materials associated with blue light therapy, as it is a noninvasive procedure that uses light to treat skin conditions.
