What is LED light therapy?

LED stands for Light Emitting Diodes, which uses electromagnetic nonlaser light with different wavelengths to penetrate skin cells and treat skin concerns. Some light colors, like the near-infrared light, can penetrate beyond the skin to even the bones.  Although it was developed in the 1960s for green experiments in space, it gained cosmetic recognition in the 1990s and has since then been the saving grace of many.

Types of LED light

Depending on the color of the light, which emits varying degrees of wavelengths, there are different LED lights for various skin woes, and here they are in no particular order:

  • Red LED light which penetrates the skin deeper than other wavelengths and promotes collagen production.
  • Yellow LED light, which is ideal for improving skin texture and battling aging woes.
  • Blue LED light is known to fight acne symptoms and other health conditions like addiction, depression, lung malfunctions, and likes.
  • Purple LED light for anti-inflammatory and cell regeneration functions.
  • Green LED light for treating hyperpigmentation, dark circles, and black spots.

LED light therapy duration

The medically approved treatment period for LED light is a 10week period of 20 minutes sessions as well as follows up sessions and maintenance.

Skin benefits of using LED light therapy

LED light therapy is causing uproar in the cosmetic world for its numerous cell functions.

Keep reading for these functions as well as other benefits.

  1. Skin types and skin color friendly

Sensitive, white, light, dark, oily, combination, normal and dry; LED therapy can be done on all skin types and skin colors without the fear of damaging or hurting the skin.

  1. Excellent safety track record

Yes, LED light therapy uses electromagnetic lights, but these are non-harmful low lights, unlike UV rays from the sun, which are not safe for the skin.

  1. Accelerates wound healing

Collagen is a vital body protein essential for tissue repairs and cell renewal. Sadly the body produces less and less collagen as we age.  With increased collagen and elastin production, your body will regularly heal itself by collagen transportation to the wound beds, promoting skin elasticity.

Now, to how LED light accelerates wound healing.

LED light permeates the mitochondria (the energy source of skin cells) and stimulates ATP (Adenosine Triphosphate) production, vital for cell regeneration. It also works on the Fibroblast growth factors responsible for collagen production, making it the go-to to treat damaged skin and accelerate healing post-surgery.

  1. Improving skin appearance

Your skin is bound to appear younger, firmer, and more elastic with sufficient collagen and elastin. What’s more? Your skin will take on a more refreshed and rejuvenate d glow.

  1. Treats skin issues

From clearing acne, eczema, psoriasis, rosacea, spots, and other blemishes and improving wrinkles, fine lines to healing wounds, sunburns, and scarring, LED light therapy is one of the most effective ways of treating many skin problems.

  1. Available for private use

The great news about LED light therapy is that you do not necessarily have to visit your dermatologist to get the treatment. There are LED panels manufactured for home use by various brands, and you can get them in handheld wands or masks.

While there are high-quality panels out there, there are also substandard panels sold for less, which can be quite attractive. Avoid low-cost panels if you want to achieve your desired long term effect.

  1. Painless and noninvasive

Unlike surgeries and other invasive in-office skin-caring procedures, LED light therapy doesn’t introduce any instruments to the skin, inflicts no pain,


As they say, whatever has benefits will always have a few disadvantages. This is also true for LED light therapy on the skin. Notwithstanding its numerous beauty benefits, it also has its downsides – although they are usually rare and mild.  Due to these possible side effects (inflammation, redness, rashes, tenderness, etc.), ensure you have your dermatologist’s approval before going on with the therapy.
