What is Blue Light Therapy and How Does it Work?
Blue light therapy, also known as high-energy visible (HEV) light therapy, is a non-invasive treatment that uses blue wavelengths (405–470 nm) to target the top layers of skin. It works primarily by interacting with porphyrins produced by acne-causing bacteria, generating reactive oxygen species that eliminate P. acnes without damaging surrounding tissue. By modulating sebum production and reducing inflammation, blue light therapy not only clears existing breakouts but also helps prevent new ones. It’s frequently combined with red or infrared wavelengths, topical treatments, or in-office phototherapy to address multiple skin concerns at once.THE BLUE LIGHT DEVICE CAN BE USED FOR MANY SKIN PURPOSES. SOME OF THE COMMON BENEFITS INCLUDE:
- Acne clearance – destroys P. acnes bacteria
- Sebum regulation – balances oil production
- Reduces redness – calms inflamed skin
- Minimizes pore size – improves texture
- Enhances skin clarity – fades post-inflammatory marks
- Supports barrier health – promotes epidermal turnover
THE BLUE LIGHT DEVICE CAN ALSO BE USED TO HELP HEAL FROM WITHIN. SOME OF THE COMMON BENEFITS FOR THIS INCLUDE:
- Decreased inflammation – lowers pro-inflammatory cytokines
- Accelerated wound healing – stimulates keratinocytes & fibroblasts
- Improved lymphatic drainage – reduces puffiness
- Enhanced cellular repair – activates antioxidant pathways
MISC. BENEFITS FROM BLUE LIGHT THERAPY INCLUDE:
- Mood enhancement – supports circadian regulation
- Neonatal jaundice relief – breaks down bilirubin in newborns
- Scalp health – helps manage mild dermatitis
- Boosts efficacy of topical serums – complements acne-fighting treatments
