These unstable molecules damage skin cells and accelerate ageing by breaking down collagen and elastin.

Studies have shown that blue light can affect the skin, primarily in people with melanized skin or dark spots. According to a study by the Journal of Investigative Dermatology, blue light causes more redness, swelling, and over-pigmentation when human volunteers are exposed to blue light and UVA light in the same proportions obtained from the sun. However, it occurred only in more profound subjects skin tone.
