Tired of all the pricking, pinching, burning, or freezing involved in traditional skincare treatments? Maybe it’s time to learn about light stimulation and why this is the latest luxurious treatment for your skin.

Whether we talk about the full-body bed at the salon or at-home treatments, LED treatments have quickly risen to the status of “unsung heroes of non-invasive skincare.”

As part of light stimulation, LED (Light-Emitting Diode) lights are a surface-level way of treating several skin conditions. Depending on the various light treatment, this therapy can treat acne, reduce signs of aging, such as fine lines, age spots and wrinkles, or simply accelerate the healing of cuts or other superficial wounds.

What are LED lights?

Before we further explain the way LED lights work, we must mention that the process used for these light treatments is not only safe, but it also produces long lasting results.

When LEDs were first mass-produced in the 60s, their main usage was limited to camera or alarm clock battery alert lights. LEDs were restricted in their usability by the fact that they could only emit red, green, or yellow light.

However, a few years ago, NASA scientists noticed that plants would grow faster under a certain wavelength of light. It was a small step between applying light stimulation to plants and skin. Before it became a useful tool for skin cancer treatment and cosmetic rejuvenation, light therapy held NASA’s interest for their ability of speeding up the healing of wounds.

How does light stimulation work?

In simplest of words, skin cells are stimulated by light’s wavelengths (or colors). Collagen circulation and growth is encouraged by applying LED stimulation. This particular method of rejuvenating the skin has been proved effective and non-invasive in the repair of common skin damage.

Collagen – and elastin – helps the skin keep its strength and flexibility. LED lights can penetrate through the epidermis, which then has the effect of youthful-looking skin.

LEDs and skincare

Light has different wavelengths represented by each color of the spectrum. Given that each of these wavelengths penetrates the skin to a different degree, different colors will have different effects on the skin.

As far as skincare treatment is concerned, most LED devices use infrared, amber, red, and blue light. Even though some devices combine the colors to create an overall skin treatment, others use them exclusively to focus on certain concerns.

  • Infrared – accelerates skin recovery and wound healing
  • Amber – stimulates the production of new collagen and elastin
  • Red – promotes circulation, reduces inflammation, maximizes cellular structure
  • Blue – stimulates production of oxygen radicals to destroy acne-causing bacteria.

Main attraction

LED treatments present a high interest for their ability of treating the skin without damaging it. Unlike a tanning bed, LED therapy does not heat the skin, preventing any possible thermal damage to the dermis.

It also helps that with light stimulation, there’s no burning (like in the case of lasers), and no need to remove skin (like with painful acid peels). Instead, the magic happens completely painlessly with the power of light wavelenghts .

Professional treatments vs. LEDs at home

Let’s review what we’ve learned so far: light stimulation is painless, non-intrusive, doesn’t damage the skin, and has effective results. What’s the catch? To make this wonder treatment work for you, you need long-term dedication. In other words, it’s not enough to have one light therapy session.

  • Going to the aesthetician’s office

For substantial collagen building plus acne reduction, patients should follow an in-office regimen established by their dermatologist or aesthetician. Generally, you will need a two-week period of daily exposure, followed by bi-monthly visits. Depending on your needs and the light you use, the period might increase or decrease.

Light therapy session length: 15 minutes

Cost per light therapy session: $150-$300

  • Taking the matter into your own hands

Worried you won’t make it to the facialist as often as you’d like? It’s worth investing in an at-home LED device. However, dedication is still key, just like with in-office appointments.

At-home LED session: 20 minutes/1-2 times a week

Cost of at-home LED device: $120-$300
