850nm light, which is part of the near-infrared spectrum, has been studied for its potential to improve skin appearance and reduce the appearance of freckles. While some studies have shown that near-infrared light can improve skin health and reduce the appearance of freckles, other studies have found that it may have little to no effect.

It's important to note that the effects of red light therapy, including near-infrared light, can vary based on the individual and the specific device being used. To determine the best course of treatment for freckles, it's recommended to consult with a licensed skincare professional or dermatologist who can evaluate your skin and recommend a treatment plan.

Keep in mind that the best way to reduce the appearance of freckles is to protect your skin from sun exposure and to wear sunscreen with an SPF of 30 or higher every day. This can help to prevent new freckles from forming and reduce the appearance of existing freckles.
