630nm (Superficial Red Light) Features: Energy is concentrated in the epidermis and preferentially absorbed by hemoglobin. Benefits: Improves skin redness and redness (dilates capillaries, promotes blood circulation, and accelerates superficial wound healing (such as abrasions and post-laser skin repair). Intended for: Sensitive skin, rosacea sufferers.
660nm (Dermal Red Light) Features: Penetrates deep into the dermis and is efficiently absorbed by mitochondrial cytochrome C oxidase. Benefits: Stimulates collagen synthesis (a key anti-aging treatment, reduces fine lines). Inhibits Propionibacterium acnes (combined with blue light for enhanced results). Activates hair follicle stem cells (for the treatment of androgenic alopecia).
810nm (Superficial Near-Infrared Light) Features: Penetrates deep into the fascia, providing both anti-inflammatory and neuromodulatory effects. Benefits: Relieves arthritis pain (inhibits synovial inflammatory factors). Promotes peripheral nerve regeneration (relieves numbness in diabetic neuropathy). Improves cerebral blood flow (transcranial irradiation supports cognitive function). Research Support: FDA-approved for chronic pain management.
830nm (Mid-Range Near-Infrared) Features: Energy is concentrated in muscles and lymphatic vessels, suitable for metabolic issues. Benefits: Accelerates lactic acid clearance (relieves muscle soreness after exercise); Promotes lymphatic drainage (treats upper limb edema after breast cancer surgery); Softens deep scars (repairs adhesions after cesarean section).
850nm (Deep-Range Near-Infrared) Features: Deepest penetration, affects bones and visceral capsules. Benefits: Promotes callus formation (accelerates fracture healing after surgery); Relieves chronic visceral inflammation (such as pelvic inflammatory disease and prostatitis); Improves brain metabolism (adjunctive therapy for Alzheimer’s disease).
Golden Principles of Device Selection Accurate Wavelength: Reject false claims of “600-1000nm full spectrum” and aim for a ±10nm tolerance. Medical-Grade Certification: FDA/CE-certified devices are preferred.
Precautions ❌ Avoid prolonged (>20 minutes) high-power exposure to the same area. ✅ Protect the eye and thyroid areas. ⏳ Cumulative Effects: Continue use for 3-6 months, as cell repair requires cycles. ✨ Summary: 630-660nm: Specializes in skin issues, anti-aging and anti-inflammatory for the “face”; 810-850nm: Addresses deeper pain and repairs neuroskeletal issues for the “underlying”; Combination Use: Mix and match according to your needs; 1+1 is greater than 2!
