In the 1990s, LED technology was discovered by NASA as a way to grow living organisms, such as plants, in space, the LED lamp used was ten times brighter than the sun. Thus, it had the benefit to accelerate the cellular production of plants and the process of photosynthesis.

Few years later, LED technology was tested on the skin, which led to the discovery that LED light also stimulates the production of skin cells. This discovery introduced the use of LEDs to treat skin damage, acne, wrinkles, stretch marks, burns, etc in a painless, non-invasive, soothing, and relaxing way.
Someone might ask, what are the benefits of led light therapy?

A Non-Invasive Anti-Wrinkle Treatment

Red LED light acts simultaneously on two processes of skin aging:
First, it boosts fibroblast proliferation and activity, which results in increased production of natural collagen, elastin, and hyaluronic acid.
Secondly, it prevents aging by inhibiting the production of collagenase and hyaluronidase, enzymes responsible for the skin breakdown that occurs with age.
In 6 to 8 sessions, twice a week, the skin becomes smoother and more toned. Its texture refines, with tighter pores and a more radiant complexion.

Treats Acne and Oily Skin

Blue light targets the sebaceous glands (oil glands) located just under the hair follicle. The blue LED light makes the sebaceous glands less active. This means that they will produce less oil, hence fewer acne breakouts. The blue light is also known to have strong anti-bacterial properties that can benefit all acne-prone skins.
Comedones, blackheads, and pimples are greatly reduced.
Many studies report an improvement in inflammatory acne of more than 50% at a rate of 2 sessions per week for 6 weeks with blue LEDs alone.

Increases The Effect of Scrubs and Microdermabrasion

It is an ideal complement to surface treatments such as scrubs and microdermabrasion because it acts on the deepest layers. For example, a scrub, followed by a session of 15 to 20 minutes, helps to accentuate its lifting effect and boosts its deep anti-wrinkle activity.

Ideal as a Complement to Peeling

Combined with peeling, the LED optimizes the results. A 10-minute LED session followed by a peeling reduces the total remission time by more than 60% and strongly prevents the risk of hyperpigmentation after the session in darker skins. Never again will a peel be a source of stress!

Reduces Stretch Marks

Whether new or old, stretch marks can be treated thanks to the action of LED on fibroblasts located deep in the skin. Its action is perfectly complementary to techniques acting on the surface such as micro-needling, maximizing its benefits while reducing its side effects.
After 8 sessions, stretch marks are visibly reduced.

Calms and Prevents Post Cosmetic Treatments Side Effects

Cosmetic treatments (peeling, dermabrasion, fractionated laser or injection) have ephemeral side effects, such as redness, swelling, bruising, inflammation and irritation.
LED technology is a miracle solution to neutralize these rednesses or swellings! Indeed, less than 24 hours after a session, most of these effects will have disappeared.

Reduces The Appearance of Blood Vessels, Redness, and Chronic Inflammation

Due to the soft and non-invasive nature of LED light therapy, it presents an ideal treatment for skin suffering from redness or chronic sensitivities. The effects of yellow light on redness are recognized and highly appreciated.

Wound Healing and Muscle Recovery

Low-level therapy is used. It speeds up wound healing and also reduces the appearance of scars. It affects cells and controls their rejuvenation and production.

Helps Against Hair Loss

Multiple causes can trigger hair loss, including stress, pollution, seasonal or environmental changes, menopause, hormonal disorders, inflammation, aggressive dyes, etc.
The effects of LED treatment on hair loss are so remarkable that the FDA has approved it for alopecia treatment.
After 10 sessions, limited to one session per week, the hair is densified.

Therapy for Atopic Dermatitis

It is used as a monotherapy treatment for atopic dermatitis, which is an itchy inflammation on the skin. It develops mainly in childhood. LED light therapy is applied to patients who haven’t responded to other topical treatment procedures.

Treats Vitiligo

This is a disease that causes loss of skin color blotches when pigment-producing cells die. When exposed on the skin, red light stimulates melanocyte migration and multiplication leading to repigmentation of the patches.

Therapeutic Procedure for Led Light Therapy

Each LED treatment program takes less than thirty minutes. Averagely, the best results are achieved between eight to twelve weeks. You are, however, advised to take the therapy two to three times a week.

Some therapists require you to lie down under the lights directly while others use LED light-infused wands that are directly put on your skin.

You can still use LED light therapy at home. Some devices come in the form of masks that emit light at a specific wavelength that can penetrate the skin. It produces different light colors, and each color targets particular cells and hence producing different results.

To be precise, the red light stimulates collagen production while the blue light reduces the redness caused by inflammation. An LED facial uses clinically proven wavelengths and is, therefore, not a cause for any alarm. You are required to keenly read and follow the instructions in the manual of the device you purchase.

When used consistently, the reactions start becoming evident. Everyone reacts differently to this therapy according to their differences in skin condition. If you have lost weight in recent times, or you have spent too much time in the sun, the results may take longer but will eventually be visible.

Is Led Therapy Safe?

The LED light does not have contra-indications of any known kind. It is, therefore, suitable for all types of skins. LED’s do not contain ultraviolet rays and are therefore safe for regular use. It does not cause any burns like other skin care routines such as chemical peels.

Side effects are rare. If present they may include;

  • Increased inflammation.
  • Redness
  • Rashes
  • Hives
  • Tenderness
  • pain

It is crucial to follow all instructions given either by the therapist or the manufacturer of the therapy device.

After successful therapy, you will require maintenance products to ensure the skin remains with its acquired characteristics. You should, however, not use this light therapy if you are on Accutane for acne or if you are experiencing skin rashes.

Is LED Light Therapy Safe for The Eyes?

The use of eye protection during LED light treatments is extremely important for your eyes. Indeed, even if most light therapy devices on the market are designed to filter harmful ultraviolet (UV) rays, the light produced during treatments is generally extremely bright and intense, which is likely to damage the cells of the eyes.
The best solution to this problem is to wear special FDA approved goggles that have protection against UV rays.


Generally, it is evident that LED light therapy is suitable for use. When used as directed and all instructions and procedures followed, LED light therapy will leave your skin sparklingly spotless without blemishes. It is also a safe means of relaxing as it is non-invasive. It does not consume time because even after the therapy is done, there is no recovery time needed; therefore, you can go on with your day to day activities. It is a remedy to calm areas of irritation and brightens your skin.

Everyone loves a radiant skin without really struggling with pain and with zero downtime. This light therapy is the answer. What are the benefits of led light therapy? As proven above, they are numerous.
