In This Safety Guide
1. Is Red Light Therapy Generally Safe?
Yes. Photobiomodulation is FDA-cleared and Health Canada-compliant for home and clinical use.
Unlike sunlight or tanning beds, Kala devices emit specific narrowband wavelengths (660nm Red and 850nm NIR) that contain zero ultraviolet (UVA/UVB) rays. They do not cause DNA damage, sunburns, or photo-aging.
2. Possible Mild & Temporary Side Effects
Side effects are rare and typically resolve within 15 to 30 minutes:
- Temporary Skin Redness (Erythema): Increased capillary microcirculation brings fresh blood flow to the skin's surface, creating a mild healthy flush similar to a brisk walk.
- Mild Detox / Purging (Rare): If using 415nm Blue Light for acne, minor initial blemish surfacing can occur as bacteria are eliminated.
- Slight Eyestrain: Staring directly into bright LED diodes without blinking or protective goggles can cause temporary light glare.
3. Eye Safety & When to Wear Goggles
* Kala Face Mask: Features integrated black medical-grade silicone eye shields that protect your retinas while allowing you to keep your eyes open. * Kala Panels (Pro, Elite, Quad): Kala includes blackout safety goggles with all panel orders. While ambient closed-eye exposure is generally safe, always wear protective eyewear when treating facial areas close to panels.
4. Medical Contraindications: When to Consult Your Doctor
Photosensitizing Medications
If taking Accutane, Tetracycline, Retin-A, or chemotherapy drugs that increase light sensitivity, consult your dermatologist before treatment.
Pregnancy
While red light on the face/limbs is safe, direct high-intensity NIR exposure over the developing abdomen is not clinically studied.
Active Thyroid Conditions
If you have untreated Hyperthyroidism, avoid holding high-intensity NIR panels directly against your neck without physician guidance.
