Red Light Therapy: The Complete Guide

The skin should benefit from treatments without side effects. Unlike other methods that may damage the skin, we believe in developing scientifically supported methods that are safe and natural. 

Light therapy treatments use light wavelengths to stimulate the skin tissue. This type of light is safe for the skin and it is not to be confused with UV light. Light therapy is as safe as regular indoor lighting.

This guide includes what red light therapy, how it works, and its benefits to the skin. This technology has a wide range of clinically-proven benefits and is super easy to add to your beauty routine. Celebrities even use this skin treatment to get ready for an event. 

What is Red Light Therapy?

Red light therapy is a type of therapeutic intervention or photo biomodulation that stimulates cellular activity with light-emitting diodes (LEDs) or low-level light treatment to repair and boost skin health. The correct red-light wavelength generates cellular responses that activate collagen and elastin production, the two vital proteins associated with skin firmness that prevents loose and saggy skin.

Treating the skin with any red light does not guarantee results; it must be the correct and most effective red-light wavelength to penetrate the skin at a cellular level. Photo rejuvenation,? LLLT (Low-Level Laser or Low-Level Light Therapy), LILT (Low-Intensity Light Therapy), bio stimulation and photo biomodulation can only happen under certain wavelengths.

Is Red Light Therapy Dangerous?

No, red light therapy is not dangerous. This beauty treatment is safe and gentle on the skin. The use of red light therapy has been studied for more than 50 years, and no risks or contraindications were reported. However, it is advised for you to consult your physician before using light therapy on your skin if you have concerns over pregnancy, medical conditions, or are taking medication that can cause light sensitivity.

Avoid using light therapy devices on areas of the skin that have sunburns, recently applied any topical solutions or agents like chemical peels, or if you are sensitive to light.

What Are the Benefits of Light Therapy Treatments?

Light therapy is a popular treatment with proven benefits helping to reduce the appearance of crow's feet, laugh lines, or wrinkles on the eye contour by stimulating and increasing collagen production. Additionally, the therapy evens out skin, repairs sun damage, aids in the reduction of redness, capillary breakage, and flushing. Most doctors use laser treatments to help fade scars and stretch marks, thus providing you with a natural glow from within. Light therapy treatment benefits are extensive and can be used to address different skin concerns. Discover below how skin can benefit from light therapy: 


Acne is frequently associated with inflammation. Red light therapy helps to reduce redness, oil production and inflammation. It's the ideal treatment for mild-to-moderate acne.

According to a study in 2018, acne and skin conditions are usually associated due to the influence of an impeded skin barrier from both states that could be further exacerbated by home topical acne treatments. Most acne solutions involve the use of chemical ingredients that can dry out and damage acne-prone. This is why we set out to create a chemical-free, non-topical treatment as not just a solution but a substitute for harsh chemicals.


Red light is a popular solution with anti-aging benefits that can help to reverse and delay signs of aging. In addition, it can help to reduce inflammation, accelerate wound healing, and provide pain relief.

Anti-aging is one of the most common reasons why people use laser treatments: numerous studies support its positive anti-aging impacts of blemish reduction and rejuvenating chemical production. Red light therapy stimulates collagen, hyaluronic acid, and elastin production in the skin as per a study in 2019 published in The Journal of The American Academy of Dermatology.

Low-level infrared light therapies, in turn, can aid with skin tolerance, fine lines, texture, pore size, and wrinkles, making them ideal "for every day, at-home treatment for individuals with photo-damaged and photo-ageing skin."

Blemish Removal

Red light increases blood circulation and oxygen levels in the treated area, helping aged and blemished skin to repair and renew itself quickly. By repairing tissue at a deeper level, it reduces scars and the visual appearance of marks.

Hair Loss

Some studies show that light therapy is an effective solution for alopecia—specifically, androgenetic alopecia referred to as female and male pattern hair loss

It is best used in the initial stages of losing hair to help strengthen the hair follicle and stimulate growth. Severe hair loss/thinning is not treatable with light therapy as the hair follicle is already damaged.

How does red light work?

Red light can easily penetrate the deeper layers of the skin to reach vital proteins, such as elastin and collagen. The cells absorb photons of red light and transform them into energy.

The energy is then used to stimulate elastin, collagen, and the production of adenosine triphosphate (ATP), resulting in more power for the cells to utilize. It improves blood circulation and oxygen supply to the skin while still regenerating damaged tissue, resulting in better skin texture due to higher collagen formation and oxygenation. Red light has the unique ability to reduce bacteria and inflammation and is reported to combat pre-cancerous lesions.

How often should I use red light?

While each device will have its recommended usage time, it is recommended to use red light therapy daily on the skin for 5-10 minutes.

Long-term regular use gives the best results and people that use it for four to six weeks see much more noticeable results. Light therapy requires multiple treatments to start getting the best benefits. A home device would work out to be much more cost-effective than going to a salon and is something that can be easily incorporated into your daily beauty routine.
