What is Light Therapy?
LED – which stands for light emitting diode – treatments use varying light wavelengths to target and treat skin issues. Originally developed by NASA as a part of plant growth experiments on shuttle missions, LED treatments were later discovered to be helpful in healing wounds. While they have been around for good thirty years, light therapy treatments were previously confined within the four walls of an aesthetician’s office. Recently, at-home light therapy masks and other beauty tools have brought this innovative skincare treatment (quite literally) into the palm of our hands.
Contemplating investing in an at-home light therapy tool? Here’s how to determine what colored light best suits your skin concern.
Blue light is most suitable to treat acne-prone skin. The antibacterial properties of blue light help kill acne-causing bacteria, thus treating and preventing breakouts. It also helps fight sun damage, diminish stubborn acne scars, and regulate oil glands.
Red light – the most commonly used LED color in at-home devices – helps soothe the skin of redness and scars, helps fight signs of aging by boosting cellular regeneration and circulation. Red light also helps retain moisture, resulting in healthy hydrated skin.
Known to penetrate deeper into the skin’s layers than any other LED color, infrared light helps combat signs of aging by boosting collagen and elastin production.
Green light not only helps calm the skin, but also reduces pigmentation and sunspots, and repairs broken capillaries. Green LED is usually found in combination with other colored lights in at-home beauty devices.
While light helps heal the skin on a deep cellular level, resulting in healthier and plumper skin.
Yellow light fights redness on the dermis and boosts circulation. It is considered ideal for those with sensitive skin.
