| Boosts collagen & elastin production |
A clinical study found that low-intensity red (640 nm) and near-infrared (830 nm) light therapy significantly increased collagen and elastin synthesis in human dermal fibroblasts.(Glamour, Lippincott Journals) |
|
| Stimulates skin rejuvenation |
Controlled LED phototherapy demonstrated effectiveness in skin rejuvenation through objective histologic and ultrastructural improvements.(ScienceDirect) |
|
| Increases hyaluronic acid and elastin |
Exposure to low-level red and infrared LED light boosted expression of hyaluronic acid synthase (HAS2) and elastin proteins in skin cells.(JAAD) |
|
| Promotes wound healing (cellular level) |
In an in vitro scratch wound model using fibroblasts, red light at 661 nm (within a dose range of 3–4.5 J/cm²) enhanced fibroblast proliferation, migration, and wound closure.(PMC) |
|
| Supports wound healing in skin |
A review of low-power LED and laser therapies noted increased collagen synthesis, fibroblast proliferation, angiogenesis, and granulation tissue formation—all key to wound repair.(PMC) |
|
| Accelerates wound healing & reduces scarring |
In a mouse model, red light (630 nm) significantly accelerated wound closure, promoted more collagen synthesis, and resulted in smaller scars compared to control.(Nature) |
|
| Improves circulation to hair follicles |
Stanford Medicine reports that red light causes vasodilation—expanding blood vessels—to deliver more blood and nutrients to hair follicles, supporting hair regrowth.(Stanford Medicine) |
|
| Stimulates collagen, fibroblasts & circulation |
Cleveland Clinic notes red light therapy stimulates collagen and fibroblast production and boosts blood circulation—all fundamental to skin repair and health.(Cleveland Clinic) |
