LED Light Therapy

LED light therapy is a widely accepted medical treatment with no side effects, originally invented by NASA to help wounded astronauts heal their wounds. Visible light, the seven-coloured segment in the picture below, is also the zone utilised by most existing LED light therapies (the latest technology is useful up to near infrared). The specific wavelengths of light are absorbed by the skin and converted into internal energy by the cells, boosting cell metabolism and synthesis and improving the condition of the skin.

  The role of the different bands

Blue Light：At a wavelength of around 420nm, it kills acne bacteria, balances oil and helps eliminate acne and blackhead problems. However, blue light penetrates to a depth of just 150 microns and does not reach the sebaceous glands.

Red Light：Red light with a wavelength of around 630nm is most commonly used and has a broad anti-ageing effect, acting on the mitochondria and activating cells to promote collagen production, eliminate sagging and restore elasticity. Red light penetrates well and also acts to heat microvessels and improve microcirculation in the skin.

Orange Light：It makes the skin firm and elastic and also lightens acne marks and prevents the formation of pits, making it perfect for fighting the first signs of ageing.

Green Light：It improves hyperpigmentation, relieves jaundice and calms the skin to even out skin tone.

LED light therapy safety：

Compared to other light of the same wavelength, LED's light is softer, the whole process is non-toxic, chemical-free, non-invasive, requires no recovery time, has no side effects and the skin feels warm and relaxed, so it can be considered very safe. Do not apply photosensitive skin care products before use.

Common types of LED beauty devices：

There are three main types of home beauty devices on the market today, the handheld type, the Large Diwali, and the face mask.

l Handheld - easy to carry, limited strength and time consuming, harder to hold on to with sore hands, suitable for topical use.

l Large Diwali - more expensive and more powerful, but there is a distance from the face and also a power dispersion. Generally when using it you can only lie in bed or on the sofa, nothing can be done and it is difficult to hold it in, and it is very bright and easily affects people in the same room.

l Face Mask - the most popular and easiest to use - is worn directly on the face and usually comes with its own eye protection like silicone, which blocks the LED light from entering the eyes while seeing out. You don't have to adjust the distance between yourself and the lamp, so you can swipe your phone and read a book while using it, which is very user-friendly.

What to look for when choosing an LED beauty device?

Firstly, quality.

The quality of the light beads is important, try to buy regular brands with certification and the wavelengths should meet the appropriate standards to be useful. It is best to have a narrow spectrum, with the wavelengths of each type of light written clearly.

Secondly, optical density.

To put it in a general way, the light output should be sufficient, which can be seen from the number of LED lights that have been distributed in the product.

Thirdly, insistence.

A home face mask beauty device means that in meeting the two conditions mentioned above, it is important to be persistent if you want outstanding results. Choose the one that suits you and use it consistently every day/week.
