LED Phototherapy Skin Rejuvenation: How Does it Work?

LED light therapy is a well-known non-invasive treatment for acne, wounds, skin issues, sun damage, etc. You can either get this treatment by visiting a dermatologist or using a home device. However, how exactly does it work?

If you are interested in understanding more about how LED phototherapy skin rejuvenation works, then you are on the right page. This article will discuss how this light therapy works and whether or not it's the best option for you.

What is LED Light Therapy?

LED means light-emitting diode. And they've been around since the 1960s but are now used for treating the skin. Their original function was for space-based plant growth experiments.

Varying LED light wavelengths, such as red and blue, permeate the skin with varying depths. When this happens, it triggers biological functions to heal and restore the skin.

Blue Light

According to professionals, this light lowers sebaceous gland (oil-secreting glands) activity. This reduced activity results in lesser oil production, thereby reducing acne symptoms.

Blue light is bactericidal for acne-causing bacteria and, according to animal research, can accelerate third-degree burn healing.

Red Light

Red light is good for improving aging signs, scarring, and minimizing skin inflammation. It acts on fibroblasts- skin cells that produce collagen.

Collagen is a protein that is present in the skin as well as other connective tissues. It functions in skin healing. The older a person gets, the lower their collagen production - this is what causes aging signs.

LED Light Therapy Advantages

The main advantage of LED light therapy is safety. Research says that it has an incredible safety profile. It does not use UV rays so is acceptable for routine use.

Also, LED light therapy doesn't result in burns compared to laser therapy or a chemical peel. It is a safe treatment choice for all skin types and colors.

Aside from that, it is also useful for treating several skin conditions, including; acne, eczema, rosacea, dull skin, scarring, sun damage, psoriasis, wound healing, and other inflammatory skin problems.

Potential Side Effects of LED Light Therapy

Generally, LED light therapy is a safe procedure. It is non-invasive and doesn't cause burns or pains. However, experts are unsure of its long-term effects.

Short-term complications are rare. They include:

• Rashes
• tenderness
• skin redness
• inflammation

Persons taking medications like isotretinoin to treat acne, or other topical ointments that can increase light sensitivity, should stay away from LED light therapy.

If you have a skin condition, we advise that you consult your Dermatologist before using LED therapy.

How Does it Work?

You can either have your treatments at an expert's office or at your home by using a home device.

If you opt to have it done at a clinic, the dermatologist may either tell the person to lay down beneath LED lights or use an LED wand directly on the person's skin. Each session takes about 20 minutes, and you may require almost 10-sessions.

For convenience, you may want to consider at-home devices since no appointment is required; they may, however, be less efficacious. It is crucial to follow the instructions of the manufacturer when using these devices.

EvenSkyn has one of the most promising LED light therapy devices for home application. Opting for home treatments can significantly help you save time and money.
