A controlled study on 137 participants using 633 nm and 830 nm LEDs twice weekly for 12 weeks showed a 31% reduction in periorbital wrinkles. This wavelength combination matches the output of our dual-wavelength devices.

Research involving near-infrared and red light demonstrated improvements in dark circles and under-eye puffiness, thanks to enhanced microcirculation and lymphatic drainage—mechanisms also activated by our under-eye LED panels. (Source: Nguyen et al., 2024, “LED therapy for periorbital aging”, PubMed, PMID: 39133416)
Gene expression studies revealed that skin cells exposed to 640 nm and 830 nm red/infrared light significantly upregulated collagen, elastin, and hyaluronic acid within 72 hours. This aligns with the photobiomodulation profile of our LED panels.

Watch as our EMS (Electrical Muscle Stimulation) technology works beneath the surface—gently yet powerfully activating facial muscles to stimulate ATP production and support cellular renewal. In trials using our EMS system, participants experienced revitalization of the under-eye area, including visible reductions in puffiness, eye bags, and signs of fatigue.

Our EMS devices deliver low-level electrical currents proven to enhance mitochondrial activity and boost adenosine triphosphate (ATP) production in skin and muscle cells. This fuels collagen synthesis, cellular repair, and visible skin rejuvenation.
(Source: Alon et al., 1992, “Electrical stimulation and ATP production in human muscle cells,” Physical Therapy Journal)
Consistent EMS use helped reduce fluid retention and increase lymphatic drainage in the periorbital region, leading to a visible decrease in under-eye puffiness and bags. These results mirror the outcomes observed with our proprietary under-eye EMS applicators.
(Source: Ghasemi et al., 2022, “Effects of facial EMS on skin condition and muscle toning,” Journal of Cosmetic Dermatology)
EMS stimulates micro-contractions in facial muscles, promoting tone and lift. In studies using similar EMS frequencies and intensities to our device, participants reported increased firmness and reduced sagging under the eyes after just 4–6 weeks.

Wrinkles

Traditional skincare primarily works on the surface, while light therapy penetrates deep
into the skin, activating cellular vitality at the source.Through photobiomodulation, light therapy stimulates collagen production essential for skin firmness and elasticity—helping to reduce wrinkles caused by sagging. It also enhances cellular energy, accelerates metabolism, and repairs aging tissue, naturally smoothing fine lines.

Additionally, light therapy improves nutrient absorption and strengthens the skin’s defense against environmental damage, restoring a youthful glow. Despite daily light
exposure, the skin still responds effectively to targeted wavelengths like red and near-infrared light.

Wound Healing

Wound healing involves inflammation control, cell proliferation, and tissue
remodeling. Light therapy accelerates this process by energizing cells,
stimulating blood vessel formation, and improving circulation, ensuring oxygen
and nutrients reach the damaged area for faster recovery. Additionally,
light therapy promotes collagen production, which is crucial for wound repair. Collagen strengthens the skin, enhances its toughness, and reduces scar formation. For a natural and effective solution to wound healing, light therapy is a proven, trusted option.

Pain Relief

Pain is a common symptom of various health issues and a leading cause of medical visits. While traditional treatments like medications and nerve blocks have limitations, light therapy offers a proven, non-invasive, and affordable alternative with minimal side effects and high safety. Light therapy alleviates pain by modulating neurotransmitter release, reducing pain
signals, and lowering brain excitability. It also promotes the release of pain-relieving substances, offering mild but lasting relief. Furthermore, light
therapy improves blood circulation, delivering oxygen and nutrients more
efficiently to the affected area, accelerating waste removal, and reducing inflammation-related pain.This makes light therapy effective not only for acute injuries, such as sports-related or
post-surgical pain, but also for chronic pain in joints and nerves. As a sustainable, healthy form of pain management, light therapy helps restore the body to its optimal state.

Acne

Acne results from excess oil production, clogged pores, and bacterial infection.
While antibiotics are a common treatment, their widespread use has led to antibiotic resistance. Light therapy offers a non-invasive alternative,
effectively targeting acne with blue and red wavelengths. Blue light
eliminates acne-causing bacteria, reducing inflammation at the source. Red
light penetrates deeper, promoting skin repair, calming redness, and regulating
the skin’s immune response. Unlike topical or oral treatments, light therapy is
non-irritating, free of side effects, and safe for most skin types, including
sensitive skin.

Hair Growth

Hair loss affects over half of the global population. As a drug-free solution, light
therapy is gaining recognition for its ability to stimulate hair follicles and
promote healthy hair growth through targeted red and near-infrared wavelengths. These wavelengths activate follicular stem cells, triggering the growth phase and “recharging” dormant follicles to resume hair production. Light therapy also
enhances ATP production, providing essential energy for follicular activity and accelerating cell proliferation. Additionally, it promotes vasodilation by
releasing nitric oxide (NO), improving scalp circulation and delivering more
oxygen and nutrients to the follicles.As a safe, non-invasive hair growth therapy, light therapy is an effective alternative for those seeking drug-free solutions.

Body

For effective health management and body shaping, exercise and diet are
fundamental. As a non-invasive approach, light therapy enhances fat metabolism at the cellular level, promoting more efficient fat breakdown and scientifically supported body contouring.Fat accumulation plays a key role in body shape changes. Light therapy utilizes specific wavelengths to target fat cells, increasing membrane permeability to facilitate fat release and metabolism. As lipids break down, fat cells shrink, leading to gradual fat reduction without the need for heat-based or invasive procedures, making it a safe complement to traditional weight management strategies. Metabolism is a critical factor in fat loss, directly influencing fat breakdown efficiency. Light therapy stimulates mitochondrial activity, boosting cellular energy production and enhancing the body’s ability to burn calories even at
rest.While light therapy offers a scientifically supported and gentle approach to body contouring, its effectiveness is maximized when combined with regular exercise
and a balanced diet.

Sleep

Sleep and mood are closely interconnected: chronic insomnia increases stress and depression risk, while poor mood disrupts sleep quality, creating a vicious cycle. Light therapy provides a natural, drug-free solution to improve both sleep and emotional well-being.

By regulating melatonin production, morning light exposure helps suppress melatonin during the day, promoting alertness and supporting a natural sleep-wake cycle. Additionally, light therapy boosts serotonin (5-HT), a neurotransmitter essential for mood regulation, with low levels often linked to depression. It also mimics natural light, making it particularly effective for alleviating seasonal affective disorder (SAD).

Consistent sleep patterns and proper light exposure are fundamental to emotional health. When sleep or mood disturbances occur, targeted light therapy can offer significant benefits.
