LED Therapy For Wrinkles

Reduces Signs of Old Age and Crow’s Feet

In this 4-week study, the following results were observed:

  • Reduced signs of aging in 90% of patients with smoother skin
  • Reduction of crow’s feet
  • Reduction of redness
  • Increased collagen levels in 100% of patients.

Reduces Wrinkles, Rejuvenates Skin and Reduces Pore Size

The stimulation of collagen and elastin production leads to the firming of the skin and thus a reduction of the appearance of wrinkles and the disappearance of fine lines.

Studies also confirm that a majority of people using red light see a reduction in the size of facial pores.

  • Pore size reduction in 90% of patients.
  • Increased skin clarity in 90% of patients.
  • Wrinkle reduction in 45% of patients.

Stimulates the Production of Collagen and Elastin

Light penetrates the skin to the dermis where collagen production takes place. Light stimulates the production of collagen and elastin to revive the skin’s healing process.

Improves Skin’s Ability to Heal

Red light helps reduce old age spots, sun spots and skin discolorations. By stimulating the production of collagen, the skin cells renew and the spots disappear.

At the end of the 4-week study, 74% of patients showed a visible improvement in the appearance of fine lines and wrinkles.

Red light has also been shown to reduce sebum secretion from the sebaceous glands, making your skin less oily.

Improves Moisture Retention, Skin Suppleness and Firmness

With increased collagen and elastin, your skin becomes firmer. Your skin’s moisture retention will improve.

Stimulates Skin Healing

Red light increases the rate of cell regeneration and thus accelerates the healing of the skin and the disappearance of scars.

Skin Oxygenation and Detoxification

Red light increases the transfer of energy between skin molecules that absorb this energy. These activated molecules cause the skin to oxygenate and detoxify.

LED Therapy For Acne

Effectively Treats Acne

Blue light helps reduce lesions. It combines the anti-bacterial and anti-inflammatory actions and thus allows to effectively treat acne, light and severe.

Studies by H.H Gold showed a 65% reduction in boils and a 62% reduction in whiteheads and blackheads.

Reduces Pore Size

Studies confirm that a majority of people using red light see a reduction in the size of facial pores.

Reduces Redness Due to Acne

This study showed an improvement of 77.93% in the appearance of inflammatory lesions due to acne.

Makes Skin Less Oily

It was shown in this study that red light reduced sebum secretion from the sebaceous glands and thus made the skin less oily.

Reduces Appearance of Scars

A 2004 study showed that the scars of patients treated with violet light, a combination of red and blue lights, were half as visible as those of patients not treated with light.

Kills Acne-Causing Bacteria

Bacteria are sensitive to light and it has been shown that blue light is the most effective at removing bacteria from your skin.

Makes Skin Smoother

Treatment with blue light reduces the size of lesions and erythema and allows a general improvement in the appearance of the skin. Your skin calms down and fewer pimples appear.

Increases Your Self-Confidence

Studies have shown that acne scars have a significant negative impact on the quality of life of young adults. Many people were complexed by their acne scars and felt that this had an impact on their social life. Blue light reduces acne outbreaks and thus reduces acne scarring.

LED Therapy For Eczema, Rosacea, Psoriasis & Redness

Reduces Symptoms of Psoriasis

During this study, patients with psoriasis were treated with red and infrared light for 4 weeks. At the end of treatment, the release rate for all patients was between 60% and 100%. Patients reported being very satisfied.

Reduces Inflammation and Redness

Blue light has anti-inflammatory properties and has demonstrated its ability to treat different types of skin inflammation.

Shnitkind, E. et al. – Anti-flammatory properties of narrow-band blue light.

Effectively Treats Psoriasis and Eczema

Several studies show that blue and red light are effective in treating psoriasis and eczema. They eliminate the cells that cause inflammation of the skin. After a few light therapy sessions, these cells calm down and the symptoms are much less visible.

Eczema is a skin condition that manifests as erythema or redness on the skin.

Exposure to red light helps remove hyperactive skin cells, which are the main cause of inflammatory skin. The red light penetrates deeply into your skin and chemically reacts with damaged tissue. Light helps heal signs of eczema over time.
