Scientific Studies On LED Therapy
We are sharing with you the findings of some of the latest clinical trials for LED therapy and its results on a number of skin conditions.
LED Therapy for treating the signs of aging & wrinkles:
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.

LED Therapy for reducing wrinkles, rejuvenating skin and reducing 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.

LED Therapy for improving 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.

LED Therapy for firmer and smoother skin:
The study showed that after several sessions of light therapy, an improvement in the complexion, softness, smoothness and firmness of the patients’ skin was observed.

https://www.ncbi.nlm.nih.gov/pubmed/16414908
LED Therapy for stimulating 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.

LED Therapy for improving moisture retention, suppleness and firmness:
With increased collagen and elastin, your skin becomes firmer. Your skin’s moisture retention will improve.

LED Therapy for 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 stimulating skin healing and regeneration:
Red light increases the rate of cell regeneration and thus accelerates the healing of the skin and the disappearance of scars.

LED Therapy for effectively treating 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.

LED Therapy for reducing pore size:
Studies 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.

LED Therapy for killing acne bacteria:
Bacteria are sensitive to light and it has been shown that blue light is the most effective at removing bacteria from your skin.

LED Therapy for reducing the 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.

LED Therapy for making 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.

LED Therapy for reducing the 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.

LED Therapy for reducing melasma & hyperpigmentation:
Green light prevents the formation of pigment. The complexion of your skin will be smooth and clear. The study showed an 80% reduction in patients.
