It sounds crazy, right? So why would light help with acne, wrinkled skin, pigmentation, and other skin ailments? To understand the foundation of this, we can start with a fun fact: Our skin absorbs light just like it absorbs toxins and moisture. When we expose our skin to sunlight for an extended period of time, it results in sunburn. This is because the skin absorbs damaging UV rays, inhibiting cellular activity and damaging the DNA, resulting in early signs of aging and even cancer.       So even though the process of light absorption is similar, LED light (Light Emitting Diode) does not produce UV. Instead, these lights are longer wavelengths that actually benefit the skin instead of damaging it. In fact, we can use certain wavelengths of light to target blood vessels or pigment, which have different effects on the skin.   So how do lights work?   Let's say you want to improve your sagging or wrinkled skin. Red light, which is probably the biggest player in light therapy, penetrates the deeper layers of the dermis, affecting specific cells, fibroblasts that produce collagen and elastin. Basically, red light goes directly to the source of the problema and ultimately, reversing signs of aging. Now, aging is definitely not the only skin concern these devices target. Blue light, for instance, which is arguably the second player in LED light treatments, is absorbed by the oil glands and stimulates a molecule called porphyrin. When this happens, these compounds kill bacteria that contribute to acne.   But you must be thinking, do these masks really work?   As long as you are consistent with your treatments, your skin will always absorb these lights and benefit from them. This is not a quick, doing it once and forget about it kind of thing. If you want to see results, you must schedule a 10 - 15 min a day regime for at least two consecutive weeks. Once you see what starts happening on your skin and how it improves it, you will most likely keep doing it a couple of times a week thereafter. And don't forget, avoid looking directly at the LEDs during your treatment, as this could cause damage to the eye. As always, I hope this has been helpful. We are always here to help :)
