What is LED?

LED’s (light emitting diodes) are encountered on a daily basis without even realizing it. Found in various types of electronics, such as traffic lights, cell phones, digital clocks and remote controls.  Just as plants absorb and convert sunlight into cellular building blocks, skin absorbs therapeutic light and uses it as a source of energy to stimulate cellular regeneration to produce collagen and elastin, kill Propioni­bacterium acnes (P. acnes) bacteria, reduce inflammation and speed healing.

The use of LED for esthetic purposes, works on a cellular level to initiate various processes that produce desired effects on the appearance of the skin.  LED therapy uses wavelengths of visible light to rejuvenate the skin. The light penetrates deep within the skin to boost radiance and treat a variety of issues, such as sun damage, acne, rosacea, eczema, psoriasis, and dermatitis. The color of the light chosen will always depend on the type of cells a professional hope to reach. Some LED devices are polychromatic, which means they utilize multiple wavelengths at the same time.

What are the benefits of LED?

Differing colors and wavelengths of light-emitting diode devices have many beneficial effects, including wound healing, acne treatment, sunburn prevention, phototherapy for wrinkles, and skin rejuvenation. LED therapy is noninvasive and an overall beneficial therapy for all skin types and conditions.

LED treatment is gentle and doesn’t involve any chemicals, involves no pain or downtime, can be used on all skin types and tones and doesn’t contain UV light, so there’s no risk of tanning, burning, or damage. Some benefits of LED light therapy include:

  • Minimize the appearance of wrinkles and fine lines.
  • Clear blemishes and minimize pores that are visible.
  • Reduce painful inflammation due to acne or extractions.
  • Improve the overall tone and texture of your skin.
  • Stimulate the naturally occurring functions in your skin like collagen.
  • Decrease the appearance of scarring, redness, and dry patches.
  • Reduce the effects of sun damage to your skin.
  • Reduce the appearance of brown spots by targeting melanin.
  • Increase the overall circulation and moisture of your skin.
  • Promote the body’s innate response of self-healing
  • Skin rejuvenation
  • Pain relief

What’s the role of Nitric oxide?

Light energy stimulates the release of nitric oxide from hemoglobin into the blood stream. When nitric oxide is released from hemoglobin, it enters the muscle cells in the walls of the blood vessels. The muscle cells relax as the blood vessel diameter enlarges, allowing more blood to flow through the vessels. As we age, the body’s ability to produce it diminishes. LED treatments as we age will assist with reducing that decline of nitric oxide.

Nitric oxide has the following three primary functions.

  • Is a neuro transmitter that plays an important role in cell signaling, allowing cells to coordinate and facilitate various processes.
  • Triggers dilatation of blood vessels and arteries to improve blood flow and discourage the formation of arterial plaques.
  • Helps regulate immune function to protect from harmful bacteria and other threats to the body.

There are many benefits that come with stimulating the release of nitric oxide into the blood stream.

  • Increases blood flow to injured or damaged tissue
  • Stimulates the production of collagen
  • Increases lymphatic system activity
  • Stimulates the production of adenosine triphosphate (ATP)
  • Increases RNA and DNA synthesis
  • Reduces the excitability of nervous tissue
  • Stimulates fibroblastic activity
  • Increases phagocytosis
  • Stimulates tissue granulation and connective tissue
  • Stimulates acetylcholine release

What’s the role of ATP?

Light based energy of specific wavelengths helps to stimulate adenosine triphosphate (ATP) production, the body’s fuel source.  LED creates cell energy for the cells to function correctly.  Over time, the human body generally becomes less efficient at producing ATP. In esthetics, we associate ATP with fibroblast cells and the synthesis of proteins like collagen and elastin to plump and firm the skin.  Human cells have so many important functions such as: breaking down molecules; producing a host of proteins, enzymes, growth factors and inflammatory mediators; synthesizing DNA and RNA; and cell signaling. Sufficient energy production is imperative to healthy cell function. Therefore, it is beneficial for LED treatments to recharge the ATP production of the all of the body’s cells.

How to incorporate LED in the treatment room?

Estheticians should recommend LED therapy as a way of attaining and maintaining healthy, collagen-rich skin. Most LED treatments are great for stand-alone purposes or can really enhance any facial treatments. Integrating LED into your spa menu will improve the existing services on your menu and provide you with a way to increase revenue. There are also many options for at home use of LED lights for the clients home regime that will also increase your retail sales.

Benefits in the treatment room include:

    • Promotes greater absorption of serums
    • Reduces redness and inflammation
    • Heals the skin after microdermabrasion, peels and laser treatments
    • Gives skin a natural glow
    • Relaxes your client with soothing warmth

Professionals can also consider treating another part of the body while treating the face for an additional fee or to introduce the technology to clients. LED therapy not only enhances clinical results and the client experience, but it also reduces social down time following breast augmentation, laser resurfacing, micro needling, injectable treatments, and cosmetic surgery.
