Why LED in Skincare- LED Home Beauty Devices, Do they work?

LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue.
Light can be a powerful tool in skin care, whether it’s an LED facial or a laser for Acne. 
What is LED Light Therapy?
LED is basically a particular light wavelength that gives off colour. Different wavelengths produce different results. But the three most commonly used in skincare and beauty are RED, BLUE and near INFRA-RED.
The skin uses the light as a source of energy to fuel the repair and rejuvenation of damaged cells, or, in the case of treating acne, kill bacteria. The energy stimulates the production of collagen and elastin, boosts circulation and accelerates tissue repair.
What types of Light are there? What do they do?
Red Light
Red light basically increases natural hydration levels, reduced redness and inflammation, shrinks the appearance of pores ,regulates oil production, improves circulation, accelerates skin repair and is a medically-approved treatment for rosacea.
Red light is used for treating the epidermis, which is the outer layer of skin. When the light is applied to your skin, the epidermis absorbs it and then stimulates collagen protein
In theory, more collagen means that your skin will look smoother and fuller, which can reduce the appearance of fine lines and wrinkles. Red LED light is also thought to reduce inflammation while improving circulation, which can give you a healthier glow.


 Blue light has been scientifically proven to kill the P.acnes bacteria on the surface of the skin that’s most commonly responsible for breakouts. Therefor it has been advised for the treatment of acne prone skin.

Combining colours has been shown to be even more effective for optimising skin health across the board than LED light treatment in isolation, with a fusion of red and blue light producing the most successful outcomes in treating acne and inflammation in particular in a 2015 study conducted by researchers at the University of Chicago.

Near Infra-Red Light

This is the most deeply absorbed wavelength, it increases cell permeability and absorption, smooths lines and wrinkles, improves elasticity, reduces pain and inflammation, accelerates wound healing and heals cystic acne.
