How do LEDs work in skincare treatments?

LEDs, or Light Emitting Diodes, work in skincare treatments primarily by targeting chromophores, which are specific molecules in the skin that absorb light at particular wavelengths. Different wavelengths of light can produce various effects, depending on the chromophores they interact with. For instance, red light is often used to promote collagen production and improve skin texture, while blue light is effective for targeting acne-causing bacteria.

When LEDs emit light, they penetrate the skin and are absorbed by these chromophores, triggering various biological responses. This capability allows for treatments that can reduce inflammation, stimulate healing, and enhance overall skin appearance through mechanisms that range from improved circulation to increased cellular energy. Each type of LED treatment is designed to utilize specific wavelengths to achieve desired skincare results, underlining the importance of targeting these chromophores effectively.
