How Light Therapy Works to Penetrate the Skin

When you see visible colors of light, you actually see what is known as wavelengths of light. Each color is output based on certain wavelengths in nanometers. The following is a chart of these wavelengths and the colors of light they output.

What you’ll find in this post:

Wavelengths-in-nanometers

Notice the color violet has a wavelength of approximately 400 nanometers while the color red has a wavelength of 700 nanometers. Now take a look at the chart below showing the differences in wavelengths. Again, the color violet has 400 nanometers, making their wavelengths shorter than the color red, which has at least 700 nanometers.

Colors with longer wavelengths, such as the color red, will penetrate deeper into the skin. The following chart shows red light penetrating as deep as the subcutaneous layer.

How light therapy targets acne

As an Esthetician, you might have quite a few clients who would love their acne reduced. So you cleanse their skin, perhaps include a microdermabrasion.

After your skin is nice and clean, top off your session with a nice violet light therapy. Violet light penetrates right on the surface of the skin, killing off the bacteria before it can get any deeper into the skin. Violet light compliments microdermabrasions in that it can soothe the skin from any redness or possible irritation. further down.

At the end of the session, your client not only feels as though their skin is cleaner than it’s ever been, but leave your spa bed feeling more relaxed than they anticipated.

How light therapy targets aging skin

What if your client was concerned about age spots? How can light therapy help?

light therapy penetrates the skin

The skin consists of 3 major layers: the epidermis, the dermis, and the subcutaneous tissue layer. The above images shows you where the melanocytes are located. Melanin, the stuff that creates color on your skin, is formed in the melanocytes. It’s main function is to protect you from sun damage, which can eventually result in wrinkles, age spots, etc.

When you’re young, melanin typically spreads color evenly throughout your skin after some sun exposure, giving you the lovely golden tan you probably want. As you age, your skin gets thinner and melanin doesn’t always spread color the way you want it to. Sometimes they accidentally pop out brown spots, where they’re not really wanted.

So what can light therapy do for these age spots?

It reactivates your skin’s cells and gets the melanin to distribute color throughout your skin the way it used to when you were younger. It’s non-invasive, painless, and it works!
