Light Therapy FAQ

What is purple light therapy used for?

Violet or purple light targets the upper layers of the skin i.e. dermis and epidermis to alleviate symptoms of acne and aging. Used in combination with other treatments, purple light therapy can help to kill acne-causing bacteria and to speed up the skin healing process. 

It can also soothe the skin, reduce redness, and minimize skin irritation caused by treatments such as microdermabrasion. 

Purple light reactivates skin cells and helps with melanin distribution to minimize the appearance of fine lines. 

Is LED light therapy the same as infrared therapy?

No. The different types of light therapy are often grouped together but they all have different characteristics and therapeutic benefits. 

LED light therapy utilizes visible light in the 400nm to 800nm wavelength and can help improve mood, regulate sleep patterns and hormones, and improve cognitive performance. Infrared wavelengths are in the invisible part of the light spectrum between 700 and 1200nm.

The longer the wavelengths, the deeper the light penetrates to heal and rejuvenate cells, and to relieve pain

How often should you do light therapy?

Most manufacturers recommend using a light therapy device daily for the first 12 weeks for best results. Depending on the initial results and your specific needs, you could later slow down the use to 3-4 times a week.

Is blue light therapy safe for the eyes?

Eye experts have found that long-term exposure to visible blue light can result in retinal stress, which increases the risk of age-related macular degeneration (AMD). Middle-aged people who are exposed to blue light are more prone to AMD than younger people are.

Is red light therapy safe while breastfeeding?

Red light therapy is considered safe while breastfeeding. Red light does not penetrate deep into your body and will not have any systemic effects on the production of oxytocin and prolactin hormones related with milk production. 

Is led light therapy safe during pregnancy?

LED light therapy is considered safe during pregnancy. LED light only affects the upper layers of the skin. Even if you were to apply the light to your abdomen, the light cannot penetrate deep into the uterus. You can safely use LED devices to control hormone-related acne common during pregnancy.

Is red light therapy good for scars?

Red light therapy is commonly used to treat skin conditions such as acne, acne scars, rosacea, psoriasis, and others. Exposure to visible light in the wavelength range of 400nm and 700nm has been found to be a gentle and effective way to heal and rejuvenate the skin. 

Heat and light encourage blood circulation and bring more nutrients to the skin, therefore improving skin appearance. 

Does light therapy work for sleep disorders?

Light therapy can help to ‘reset’ the body’s clock. Artificial light can be used to trigger the body’s circadian rhythm in the same way that sunlight does. Light therapy is typically used alongside other treatments to help with sleep disorders.

You should only use light therapy for sleep under the guidance of a doctor who is familiar with sleep disorders. 

What is light therapy for babies?

Light therapy for babies is commonly used to treat jaundice in newborns. In a light therapy session, your baby will lie in an incubator or bassinet and will be exposed to LED light. 

During this process, your baby’s body will absorb the LED light and the bilirubin in the body will be converted into a form that can be easily excreted in urine or stool.

A newborn with jaundice may need light therapy for several days. Light therapy does not damage a baby’s skin.
