Red Light Therapy Benefits
Red and near-infrared light is studied for skin quality and recovery; the research is promising in some areas and still early in others, so we don't promise specific results. At LIMFAERA, red light complements body treatments: Professional Red Light with a 45-minute body roller session ($70), and Celluma red light as a complimentary add-on to lymphatic drainage and body sculpting sessions.
How Red Light Therapy Works: Wavelengths
Red light therapy, also called photobiomodulation or low-level light therapy, uses LEDs or low-power lasers in two bands:
| Light | Typical wavelengths | How deep | Most studied for |
| Red | about 630–670 nm | Skin | Skin quality, fine lines, wound healing |
| Near-infrared | about 800–880 nm | Deeper tissue: muscle, joints | Muscle recovery, joint and muscle pain |
The light is absorbed by the mitochondria in your cells, where it may support energy production; that is the proposed reason for its effects on skin and tissue repair. It isn't UV light and doesn't tan or burn the skin.
What the Research Says
- Skin: small controlled trials report improvements in fine lines, skin texture and collagen density after several weeks of regular sessions.
- Recovery and pain: studies on muscle recovery and joint pain are encouraging but mixed in quality.
- Cellulite and fat loss: evidence is weak; we use red light alongside body treatments, not as a slimming treatment.
- How often: results in studies come from repeated sessions, usually several times a week for a few weeks, not from one visit.
Side Effects and Who Should Skip It
Side effects are uncommon and usually mild: temporary warmth or redness of the skin. Don't look directly into the light. Skip it, or ask your doctor first, if you are pregnant, have epilepsy triggered by light, a light-sensitive condition, active or past skin cancer in the area, or take photosensitizing medication such as isotretinoin or some antibiotics.
Is Red Light Therapy Safe?
Low-level red light is generally considered low-risk for healthy adults. Don't look directly into the light. Tell us before booking — and check with your doctor — if you are pregnant, sensitive to light, taking medication that makes you photosensitive, or have a history of skin cancer.
