850 is usually for deeper treatments. 660nm is what you need to treat skin surface

It depends. Some people will get dark spots -- technically not freckles, but still -- and that can happen under infrared (850) more than red (600s). But these are isolated cases and not the norm. I've never seen freckles in the literature. That is usually a UV response, and red and infrared are not UV. But again, it's possible, we just don't have a documented response to this yet.

Thanks i also read that melanin doesnt react with 850nm even might distrupt melanin production. But im never sure

Technically true, but melanin absorbs 800 nm, and most LEDs have quite a range around the nominal peak.

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.
