Red and blue light therapy are forms of phototherapy using specific wavelengths of LED light to target different skin concerns: red light for anti-aging and inflammation, while blue light is often used for acne and acne-causing bacteria.

Red Light Therapy:

Benefits:

• Wavelength: Longer wavelengths, typically between 630 and 700 nanometers. 
• Uses: Addressing signs of aging, reducing redness, and improving skin texture. 

Blue Light Therapy:

• Benefits:
• Wavelength: Shorter wavelengths, around 415nm. 
• Uses: Primarily for treating acne and preventing breakouts. 

Combined Red and Blue Light Therapy:

• Many devices and treatments combine both red and blue light therapy to address a wider range of skin concerns, including acne, inflammation, and signs of aging.
• This approach can be particularly effective for treating acne while also addressing potential side effects like inflammation and redness.
